  NEUROSURGERY
  
  CHAPTER II  
  ACTIVITIES  OF THE AMERICAN FIRST ARMY HOSPITAL AT DEUXNOUDS a 
  
  On  September 26, 1918. Casual Team No. 538 was ordered to proceed to  Deuxnouds and  to take over the French ambulance in that village, it being the  intention of the chief surgeon, First  Army, to convert this ambulance into ahead hospital.  
  
  At  noon of the 28th the first portion of the equipment of Mobile Hospital  No. 6 arrived  and continued to do so during the 29th and 30th. Because of the haste  in opening, the taking over  of the French hospital, and the functioning for the first time of a  mobile unit fresh from its  assembling point, many improvisations were necessary, and as complete  records as might be  desirable were not at all times obtained, especially in the first few  days.  
  
  In  the triage all lightly wounded were dressed and such as were  non-operative  immediately marked for evacuation. Operative cases were undressed,  bathed, and placed on  stretchers pending operation. About 90 per cent of the neurosurgical  work was lone during the  first two weeks.  
  
  Inasmuch  as no systems of permanent records in evacuation hospitals had been  established, it was necessary to improvise some method of keeping track  of at least the most  important cases received at this hospital. Each team was asked to keep  a record in a duplicating  book provided for them, of which one copy was placed with the field  medical card or its  equivalent. When a patient was evacuated, the records were passed  through the office of the surgical chief, who abstracted the more  essential points upon the patient's field medical card and  saved the complete record to turn into the consulting surgeon's office.  Unfortunately, when  teams were ordered away, records were left in the hands of men who,  although able and willing,  had had no experience previously with the system of keeping them.  
  
  The  total number of admissions up to the morning of October 15 was 815. Of  these, 403  underwent operation. leaving 412 which were dressed in the triage at  once and marked for  evacuation. These cases then had passed through, in the majority of  instances, triage at the field  hospitals and evacuation hospitals without their dressings being  changed and had come through  to Deuxnouds before being recognized as nonoperable and evacuated. Of  the 403 operations, 106  were craniotomies.  
  
  The  operative capacity of the Deuxnouds hospital was, roughly, 100 cases  per 24 hours,  of which, from the experience gained there, one would expect 25 to be  craniotomies and 15 dural  penetrations. In addition, on the above basis,100 cases would be passed  through the triage with a  dressing and for immediate evacuation. If, as is generally estimated,  10 percent of the total  casualties

  involve the head,  face, and neck, then this hospital was caring for its proportion of  2,000  casualties in 24 hours.  
  
  With  the equipment the personnel could be expanded at least 50 percent, and  in that case  such a unit could handle 200 operations, admit 400 casualties, and  handle its proportion of 4,000  in the 24 hours. This would make a total of 28,000 a week or, roughly,  100,000 a month, which  perhaps is approximately the casualty rate for the fighting at this  time in the First Army; that is  to say, one well-developed unit of this type or two smaller ones should  be able to handle wounds  above the clavicle for one army as at present organized.  
  
  Frequently  it is assumed that the retention of head cases will soon choke the bed  capacity  of a hospital. The normal intakes of this hospital estimated at 15  dural penetrations per day  (these being the only cases retained) would provide at the maximum an  accumulation of 100 per  week. In two weeks this type of case is evacuated, so that at no time  would more than 2,000 beds  be occupied.  
  
  As  a matter of experience, during the second week of function of this  hospital, the beds  occupied reached 290, but this was chiefly because of lack of  evacuation, and in spite of this  there was no choking of the hospital by retention of head cases. 
  
  CLINICAL  DATA   
  
  Deaths.- In so far as neurosurgical  conditions are concerned, the deaths from the opening  of the hospital until its evacuation by Mobile Hospital No. 8.that is  until about November 8,  numbered 67, of which 25 died without operation and 42 following  operation. These have been  classified according to Cushing's classification, as follows: 
  
  DEATHS UNOPERATED
  
  Cranial:  Group I (general shock and  sepsis from other  wouiids).............................................1  
   II (previously  operated)..................................................................................................1 
       IV (previously  operated).................................................................................................1 
       V (all moribund on  entrance)..........................................................................................5 
       VI (4 meningitis; 3 moribund on  entrance)....................................................................7 
  Wounds of head (no data; moribund on  entrance)....................................................................4 
  Dead on entrance (dural penetration; no  further  data)...............................................................1  
  Spinal cord  ------------------------------------------------------------------------------------1  
  Total-------------------------------------------------------------------------------------------21   
  
  Of  these, it may be noted that two (Group II and Group IV,  respectively)previously had  undergone operation. The records of these are as follows:  
   
  CASE  1.- A. I. J. F., No. 3270146. Wounded October 5, 1918. Field hospital  (?).Copy of  note: " (1) G. S. W. left arm; compound fracture. (2) G. S. W. head,  left. Compound fracture of  skull. 36 hours. Operation October 7: Cleaning, partial suture of  scalp; no evidence of depression  of skull. Amputation left arm after consultation. Hold." Entered Mobile  Hospital No. 6, October  12. Amputation left forearm. Suture lacerated scalpwound, left  occipital. Neurological  examination negative; X ray negative. Dressing. One suture removed from  scalp. Patient  profoundly unconscious; manifestly moribund. Died October 13. Autopsy:  Depressed fracture of  the inner plate, left occipitoparietal, with large extradural  hemorrhage; no dural penetration.  Brain saved for section.
 761  
  
  This  patient arrived profoundly unconscious, with notes of operation  performed  elsewhere and revealing no fracture. A negative X-ray and neurological  examination of the  patient confused the picture still further. In view of the moribund  condition of the patient and the  negative findings, it was not thought worth while to do an exploration.  The surgeon who  operated upon him would have been in a better position to judge of his  condition and the  advisability of further operative action. Consequently this case should  not have been evacuated.  
  
  CASE 2.- J. G., No. 1624243. 79th Div. 314th Machine  Gun Battery, B  Co.,admitted to A. R. C. Hospital No. 114  with following note: "X-ray: F. B. 1 cm.right side of head, 4 cm. under  skin mark, right temple. Large depressed  fracture of skull; left parietal region. 22 hours after injury.  Operation: Removal of depressed parts of bone.Brain  irrigated and macerated brain tissue removed. F. B. not removed. Hold."  Admitted to Mobile Hospital No. 6,  October 6, 1918, 11.30 p. m. A. T. S. given. October 7:Unconscious;  delirious; tosses about with left arm and hand.  Incontinence of feces and urine. Complete right-sided hemiplegia. Right  facial palsy. Large postoperative wound,  left parietal region; crow-foot incision; sutures infected; spinal  fluid oozing out. Three central sutures removed. Skin  edges infected; decompressed area size of half dollar in left parietal;  there has been considerable brain injury. No  rigidity of neck; no Kernig; left Babinski plus. October 8, 1918.  Considerable foul discharge. Neck rigidity marked.  October 9, 1918. Meningitis. Foul discharge from wound; opened more;  fragments of inner table which were loose,  removed. October 10, 1918. Died 12.40 p. m. No autopsy. 
  
  It  is impossible to convey by notes, especially such as can be placed on  a field card, the  completeness of an operation and the history of a case such as this.  Any dural penetrations  should always stay under the care of the man operating until either  evacuated to the base or dead. 
  
  Of the five  cases in Group V dying without operation, in three the foreign body had  traversed or lodged in the region of the basal ganglia. In the  remaining two the cranial damage  was extensive, partly direct laceration of brain tissue and partly  extensive "commotion" of the  brain, such as is seen in profound concussion. They were all moribund  on entrance. The  following case is typical of this group: 
  
  CASE 3.- W. H., Pvt., No. 542269, 7th Inf.,  Co. H. Field Hospital No. 27, October 8, 1918. G. S. W. skull.  Field Hospital No. 26, October 8, redressed, morphia, external heat,  small piece of high explosive taken from right  knee. Wound of thigh dressed. Mobile Hospital No. 6, October 8. Patient  entered hospital in unconscious condition.  No history other than above. Pulse 144; respiration rapid and with  apparent beginning edema of lung. Wound: G. S.  W. right anterior quadrant skull, about 4 cm. in length. Multiple C. S.  W. right leg. X ray; foreign body 1 by 1½ 2  cm. inside skull, 7½ cm. under skin mark right anterior frontal  region head on left side; 8 cm. under skin  mark on middle anterior frontal region; plane passing on the line drawn  will meet at a point giving the position of  foreign body 1 by 1½ cm., 6 cm. under skin mark on upper inner surface  of thigh, right. Foreign body A by A  under skin mark on point of heel, right. October 9, 4.15 a. m. patient  died. Autopsy: Penetrating wound right  frontoparietal region. Extensive comminution of cerebrum with softening  opposite side. Brain saved for section.  
  
  In  Group VI, three patients entered in a moribund condition, the missile  having, judging  from its course, reached or traversed the ventricle. Four died of  meningitis, one having a foreign  body traversing the lateral horn of the left ventricle, unconscious on  entering and developing  infection in 24 hours; a second entering, unconscious, with foreign  body localized in such a  position
 762 
  
  as to indicate that it  had traversed the ventricle, developed signs of meningitis in 24 hours  and  died on the seventh day after admission; a third had outspoken signs of  meningitis; and the  fourth, the foreign body had traversed one hemisphere from pole to  pole, passing through the  ventricle, while the man was profoundly unconscious and developed  meningitis in 24 hours. A  typical case is as follows:  
  
  CASE 4.- 145th Inf., Co. B, 37th Div. No notes  from field hospital. Admitted to Mobile Hospital No. 6,  September 30. Unconscious, with diagnosis of G. S. W., left parietal  region. Condition good. Entrance wound in  front of left ear just above zygoma. X ray: Foreign body 1/4 by 1 cm.  lying below mark on right ear, right  side of head to the table. Neurological examination: Complete right  hemiplegia. October 1, 4 p. m.: Temperature,  100.6; pulse, 94; deeply unconscious. Fundus examination: Disks  blurred; fields distended. Operation not considered  advisable. October 3: Symptoms of meningitis. October 4: Semiconscious.  October 7: Semiconscious; marked  symptoms of meningitis. October 8: Died from meningitis. October 9:  Autopsy. Penetrating wound left temporal  region, entering tip of temporal lobe, entrance measuring 2 cm. in  diameter, exuding quantity of pus and  disorganized brain. Acute purulent meningitis especially marked over  the base. 
  
  DEATHS OPERATED

  VII................................................2 
  VIII...............................................2
  IX  ................................................2
  Sinus (venous)  ..............................1 
  Total...........................................35
  
  The  death in Group II was due to lobar pneumonia, shown at autopsy. There  was also a  linear fracture of the skull down to the right, but with no evidence of  depression. A small and  unimportant extradural clot was present. This fracture was not  recognized at operation, and the  skull consequently was not trephined. 
  
  The records of the  patients in Group III who died are as follows:
  
  CASE 5.- G. H. P., No. 65331, 103d Inf., Co.  H. Admitted to Mobile Hospital No. 8, October 25, 5 p. m.  Wounded 7 a. m., October 24. A. T. S. given. Unconscious 15 to 20  minutes after accident, with immediate paralysis  left side of body. G. S. W., 12 by 3 cm., right parietal region, dirty  and inflamed. G. S. W. right arm and elbow,  outer surface, above and below knee, foul-smelling discharge suggesting  gas infection. X ray head: Penetrating  skull, right parietal. Numerous foreign bodies ½ by ¾ cm. in length  in wound in skull. One foreign body 1 cm.  long projects from the wound, to inner surface of the skull. No foreign  body in brain. Right arm, leg, and thigh  negative. Neurological examination: Paralysis left side of face, left  arm, and left leg. Loss of sensation to touch and  pin prick left arm and hand. Touch sensation in left hand present. Deep  reflexes left arm, left leg hyperactive. Left  epigastric, left cremasteric absent; right present. Spasticity left leg  and left arm. Left Babinski. Pulse rate 100.  October 25, 10.20 p. m.: Blood pressure, systolic 120, diastolic 80.  Operation: Excision of scalp. Block removal  decompressed skull fracture 3 cm. in diameter; dural penetration.  Subdural blood clot and contused brain
 763
  
  removed by  suction. Dural wound left open. Partial closure of scalp. Local  anesthesia, under  primary ether. Arm and leg wounds excised for drainage. Pulse 150 and  very weak, so that more  extensive procedure could not be done. October 26, 8.45 a. m.:  Convulsion, Jacksonian type, left  side of face, left hand, duration 10 minutes. Dressings changed. Pulse  120. During the next 12  hours, patient had 6 of the localized convulsions. October 30:  Continued and increasingly severe  convulsions since operation, always involving left arm and left side of  face. Left leg paralyzed;  leg wound dirty and foul-smelling. General condition never good and  became steadily worse.  Right leg shows evidence of gas infection. Died at 7.30 p. m. 
     
  The severe  shock and the sepsis  resulting from wounds other than that of the skull seemed to preclude  as extensive an operative  procedure as was advisable in the first place, and also a secondary  exploration to ascertain the  cause of the irritative phenomena, which might otherwise have been  done. A similar case with  Jacksonian attacks, on secondary operation showed a tract in the cortex  about 2 cm. deep under  considerable pressure and tension. On relief of this, the convulsion  subsided. No autopsy. 
  
  CASE 6.- H. P., No. 2257218, 361st  Inf., Co. C, Pvt. Admitted to Mobile Hospital No. 6, October 4, 1918.  Wounded October 3, 3 p. m. Was not rendered unconscious and was able  to walk. X-ray examination: Foreign body  8 by 5 cm., 20 mm. from mark on posterior surface of right thigh.  Forehead shows no foreign body. Wound of head  3 cm. above right eyebrow, 1 cm. in diameter. Neurological examination:  Right pupil greater than left; pupils react  to light, otherwise negative. Operation: October 4, 5.50 p. m. Block  excision of block and bone. Internal plate, 2 by  1½ cm., which had been driven inward and striking into dura, removed.  Escape of large amount of clear,  cerebrospinal fluid. No contusion of underlying brain noted. Dura and  scalp closed with silk. October 7: Scalp  wound infected; opened. October 8: Kernig positive. Neck stiff; lumbar  puncture done, 20 c. c. cloudy fluid  removed. October 9: Lumbar puncture, with removal of cloudy fluid.  October 10: At midnight patient died of  meningitis. Autopsy: Scalp wound only slightly infected. Dura tight.  Spreading from this is an acute, purulent  meningitis, most marked over the right cerebrum and base.  
  
  In  Group IV, there were 17 deaths, of which 1 had signs of meningitis on  admission; 1  died of severe and generalized gas burns; 3 of meningitis; 8  encephalitis; and 4 directly as a  result of very extensive intracranial damage, although this in some  cases may have been  complicated by infection. In other words. 11 out of the 17 cases were  amenable to operative  treatment.  
  
  In  the cases of meningitis, two showed signs in 24 hours, making it seem  possible that  the meninges were infected previous to operation, while the third  flared tip on the fifth day  following a very extensive herniation and encephalitis. In the first  two, the scalp was closed  tightly and not opened at any time. The third was leit open because of  the size of the scalp  defect.  
  
  Four  of the eight cases classified as dying of encephalitis had such an ex  tensive  intracranial damage that their condition was obviously practically  hopeless for operation. One of  these died of a gas infection of the brain.  
  
  The  following is a typical case:  
  
  CASE 7.- M. K., Pvt., No. 1630902, 30th Inf.,  Co. I. Evacuation Hospital (A. R. C.) No. 114, October 11.  G. S. W. head. Admitted to Mobile Hospital No. 6, October 12, A. T. S.  given. History: G. S. W. head, October 11, 4  p. m. Conscious, no vomiting. Paralysis, left; spastic. Condition fair.  Wound 2½ by 6 cm., right parietal,  parallel with sagittal suture to the right of mid line over parietal  region. Ragged, dirty, depressed fragment 1 by ½  cm. Stellate fracture radiating from depression. X-ray examination: No 
 764 
  
  foreign body. Fracture of skull through inner  table beneath wound. Neurological examination: Spastic left  hemiplegia, arm and face; arm less than lower limb. Knee jerks  diminished, left. Ankle-clonus, left. Operation: De bridement, two  sutures in the dura; closure with no drainage. October 13: Wound  dressed; considerable discharge.  Patient stuporous October 14: Wound shown increasing sanguinio-purulent  discharge. No rigidity marked.  Unconscious. October 15: Condition serious. Much foul discharge from  wound. Unconscious; no rigidity; Kernig.  October 16: Nystagmus to the left. Condition worse. Convulsion this  morning at 9; this afternoon at 1.30. Died at  5.30 p. m. Autopsy, October,17: Wound, vertex, of the skull, right  parietal region, softened brain substance exuding--Three radiating  lines  of fracture from bone defect. Opening in the dura measures 3 by 5cm.  Brain is so softened that  its removal intact is almost impossible. Right parietal lobe entirely  replaced by softened hemorrhagic mass.  
  
  The  remaining four cases represent errors of treatment, and these are  reported in detail:  
  
  CASE 8.- F. S., Pvt., No. 2965964, .314th F.  A., Co. E. Wounded October 7, 1918. French field hospital,  October 7, 1918. A. T. S. given. G. S. W. head. Entered Mobile Hospital  No. 6, October 7, midnight. History  indefinite; patient's statements uncontrolled and unreliable. Given his  name, organization, State, etc., but readily  forgets and repeats. Recognizes objects and names; knows he is in  hospital and has been wounded. Wound: Small  penetrating, left posterio-parietal,  measuring 2½ by ¼ cm. X-ray examination negative, for foreign  body. Area  of increased density size of nickel, suggestive of intracranial  hemorrhage under wound. Operation: De bridement of  scalp; fractured bone 6 by 5 cm. had been driven into the dura and  brain. Removal of bone fragments, enlarging the  opening to the size of a dollar, under local anesthesia. October 10:  Visual fields somewhat limited, homonomously  to the right. October 11: Patient much more alert. Visual fields  probably normal. October 17: Sutures removed.  Slight amount of sero-purulent material. October 24: Died at 7.15 p. m.  Progressive cerebral herniation and signs of  encephalitis.  
  
  The  condition of this patient previous to the operation seemed quite  favorable, but for  some unknown reason the block operation with wide exposure was not  done, consequently  thorough d ebridement was not accomplished. Intection ensued in the  presence of inadequate  drainage, followed by1 progressive encephalitis and death.  
  
  CASE 9.- F. D., No. 2557608, 138th Reg.  Admitted to Mobile Hospital No. 6 September 30, 1918. Unable  to talk. Slip with him says wounded in action: Day not known. Marked  S. W. of skull. Condition: Unconcious on  admission. An hour later could be rouse. Could not speak, but some  attempts to obey simple orders, such as moving  arm and leg. Wound: Severe, penetrating, over left parietal region.  Bone fragments driven inwards and down  outwards. Neurological examination: Complete right hemiplegia. Right  pupil larger than left. Right ankle-clonus.  Right knee jerks greater than left. No Babinski. X-ray findings  negative. Operation: Déebridement ; removal  of shattered bone. No foreign body. October 2: Dressing, some  herniation. October 3: Dressing; herniation increased;  slight hemorrhage. October 4: Severe hemorrhage. Herniation of almost  entire left lobe. Discharge of blood spinal  fluid on slightest cough. Died at 1.30 p. m., October 4.  
  
  CASE 10.- Pvt. No. 17X1329, Co. L, 313th Inf.  Wounded, October 1, 1918. G. S. W. head: (1)  frontoparietal; no foreign body or fracture. (2) G. S. W. 5 cm. in  length, left Rolandic area; indriven bone. Admitted  to Mobile Hospital No. 6 October 2, 1918. Neurological examination:  Spastic paralysis right side. Right facial  paralysis. Operation: De bridement. No foreign body found. Subdural  clots. Bone fragments removed. Closure  incomplete. October 3: Slight hemorrhage from dural vessels; brain  hernia. Vessel cauterized; actual cautery.  October 4: Patient died, 5.45 a. m.  
  
  In  both of these cases, the dressings were carelessly done, with  compression and damage  to the herniating cerebral tissue, followed by hemorrhage. This was  controlled only after further  rough usage, resulting in the shutting 
 765
  
  off of blood supply to  considerable areas of herniating cerebrum. Such a condition so handled  is,  of course, always progressive and followed by death.  
  
  CASE 11.- F. C., Sgt. No. 2307026, Co. G,  127th Inf. G. S. W. head. Wounded October 4, 4.30 p. m. Hit by  piece of high explosive. Unconscious for hour and a half. Vomited  directly on regaining consciousness, but not  since. At Field Hospital No. 27. A. T. S. given. Entered Mobile  Hospital No. 6 October 6, 1918, midnight. Wound:  Gutter wound over right median frontal, apparently tangential. Dirty  and protruding cranial tissue. General condition  good. Pulse 60. Weakness of arm and hand. Positive Babinski, left;  cremasteric, left; less than right. No other signs.  Operation: Wound in bone removed en bloc. Three bone fragments removed,  completing half mosaic. Cortical  bleeding started by an attempt to remove bone fragment; controlled by  cotton and finally by a small facial slip. Scalp  sutured. October 6, 3.10 p. m.: Left lower fascialis weak. Pupils equal  and react to light and accommodation. Left  arm paralyzed except for very slight movement of forearm. Left leg very  weak; no Babinski or Oppenheim.  Reflexes: Knee jerks, left greater than right; no clonus. Vomiting.  Wound dressed; blood under scalp expressed;  seems clean. Pulse rapid. October 7: Neck stiff. Optic neuritis.  Unconscious. Pulse 116.Temperature 100.6;  respiration 30. October 8: Condition much worse this morning; com-plete  left hemiplegia; stuporous. Died at 10.05  a. m.  
  
  The  tearing of the deep cortical vessel, and the consequent hematoma along  the tract,  destroyed what small chance of recovery this patient had. Examination  of wound post mortem  showed a gas infection involving the greater part of the right frontal  lobe, patient having died of  a gas encephalitis.  
  
  In  Group V, three eases died following operation. One of these entered  with a foreign  body 5 by 3 cm. in left parietal region and a herniation already  present measuring 6 by 8 by 4  cm. Patient was unconscious and hemiplegic. An unsuccessful attempt at  removal of foreign  body was made. Wound was dressed; patient died within 48 hours.  
  
  The  records of the remaining two cases are given in detail.  
  
  CASE 12.- J. E., Pvt. No. 2256961, 361st Inf.,  Co. A. Wounded October 1, 191g. Entered Mobile Hospital  No. 6, October 3, 1918, 10.45 a. m. Penetrating wound right occipital  region. X-ray examination: Penetrating  wound: Foreign body 1 1/cm. in the brain. Mid  line 7 cm. back of  external auditory meatus. No localizing  neurological sign. Operation: Block removal of fracture area through  tripod incision. Foreign body lying about 8 cm.  under the surface removed; several bone fragments also. Scalp closed  tightly. October 5: Incontinence of urine;  temperature 100?F.; no nausea or headache. Deep reflexes  very sluggish; drowsy. Disorientated for time and place.  Knows he was in 361st. Inf., does not remember any circumstances of  accident. October 7: Temperature ranged to  102? F. Patient vomiting to-day. Fungus formation, with  broken-down wound. Scalp resutured, with anterior drain.  October 8: Bloody discharge but wound holding. Opisthotonos; positive  Kernig; patient has developed meningitis.  October 9: Died at 7.40 a. m.   
  
  CASE 13.- Pvt. No. 1458990, 152d Inf. G. S. W.  head. Entered Mobile Hospital No. 61 October 1, 1918,  12.05 a. m. Extensive gutter wound of left side of head from above left  orbit upward and outward to left external  auditory meatus. No neurological signs except for motor aphasia.  
  Operation:  Local anesthesia. D bridement: Removal of bone fragments and pieces of  shrapnel from brain. Closed in layers. October 7: Lower end of wound  incision opened. Brain  irrigated with saline. Fungus cleaned away. Scalp wound sutured  tightly. October 10: Wound  suppurating; dressed daily and irrigated with sterile salt solution.  Draining profusely. Condition  fair. October 12: Redressed. Free drainage, with suppuration of wound.  Condition improved.  October 13: Redressed. Some improvement. Temperature normal. Draining  freely. October 14:  Redressed. Wound condition same; still draining freely. Temperature  102.6? F. Suspicious  Kernig. No opisthotonos. October 16: Died 4.30 p. m.

  These  cases are of special interest because once having been sutured and  having broken  down, they were again closed over the hernia. The conception in the  operator's mind of the  condition being that it was a purely mechanical thing, it was not  appreciated that while cranial  herniation is due to increased intracranial pressure, this may be  either the result of edema from  mechanical disturbances, or, what is more important in war injuries,  from infection. If the  herniation is due to a purely mechanical cause, under proper dressing  itwill shortly subside even  if the scalp is left open. If, however, it is due to infection, as in  any other region of the body, the  infected area must be adequately drained. Both of these cases, as might  have been expected  under the treatment used, did badly. 
  
  Of  the five deaths in Group VI, three were instances where the projectiles  traversed the  entire hemisphere passing through the ventricle in its course. Such  injury-according to Cushing's  experience, confirmed by this data-results uniformly in death. In time  of rush such cases should  be marked inoper-able. An instance of this class is the following:  
   
  CASE  14.- E. W., Pvt. No. 1937561, 26th Inf., Co. G. G. S. W. right side of  head, severe.  Entered Mobile Hospital No. 6 October 11. History of being wounded  October 9, 4.55 p. m.  States that he was struck by shrapnel. Not unconscious. Helmet broken.  Very severe headache,  and nauseated. Left hand has been weak since injury. No speech  difficulty. Wound: Right frontal  region, just back of hair line. Brain substance oozing. X ray shows  machine-gun bullet lying  near junction of temporal and occipital lobes on the right.  Neurological signs: Left facial  weakness. Left arm and hand extremely weak; left leg somewhat so.  Slight diminution of  sensation left. No astereognosis: Complete left homonymous hemianopsia.  Reflexes, biceps,  more lively right than left. Knee jerks, present right, absent left.  Few clonic jerks each side.  Operation: Novocaine and morphia. Complete removal of fractured skull.  Débridement of scalp  and track; through irrigation. Foreign body, machine-gun bullet;  removal of right hemisphere,  location 4½ cm. from point just above right external auditory canal  and about 9 cmn. from the  point of entrance in the right frontal lobe. Irrigated with sterile  saline. Bone fragments removed;  scalp sutured; patient's condition good. October 13: Dressed, wound  clean. Temperature 101.4? F.;delirious; stiff neck and double Kernig. Left hemiplegia present.  October 14: Died 2.15 a. m.  Autopsy: Penetrating wound, deep, right frontal lobe. Brain saved for  section.
  
  The  two remaining cases were instances of indriven bone fragments reaching  the  ventricle, and they died of meningitis. About one in four of such  wounds recover and they are,  therefore, distinctly operable.  
  
  In  Group VII, two cases died, both having a wound involving the orbital  contents, frontal  sinus, and frontal lobe. The extensive mortality accompanying this type  of injury suggests more  radical measures, which were not under-taken in this hospital, namely,  evisceration of the orbit  and establishing wide and thorough drainage.  
  
  Two  cases with traversing wounds of Group VIII died following operation,  one of the  cerebellum and one of an occipital lobe, the latter dying from a  generalized gas infection,  apparently arising from the foreign body which lodged deeply in the  neck muscles and was not  removed. In the former the foreign body traversed the right lobe of the  cerebellum, almost  completely destroying it, encephalitis of the cerebellum resulting in  death in six days.  
  
  Two  deaths are recorded in Group IX, one being the type of basal fracture  commonly  seen in civil life, and the other a fracture of the petrous portion of  the temporal bone, with  cerebrospinal fluid from the ear. 
 767 
  
  Of  these crises involving a venous sinus, one died. In this case the  approach was made  with an inadequate exposure resulting in profuse hemorrhage, packing,  and death on the fifth  day, which, however, was probably due to the effect of the missile  ranging forward and inward  to the basal ganglia. 
  
  PATIENTS  EVACUATED   
  
  The  following records are of cases that were evacuated in good condition:  Cranial-Group  I, 69; Group II, 32: Group III, 14; Group IV, 6; Group V, 11; Group VI,  1; Group VII, 1; Group  VIII, 2. Sinus (venous): 4. Total: 140. 
  
  CRANIAL  
   
    Group    1.- The majority of cases in this group were scalp wounds in which  the injury had  extended to the bone. In a few, however, the pericranium was not  lacerated. It would seem,  particularly in times of rush, that the patients in whom the laceration  did not extend to the bone  might be evacuated without operation. It is realized that there might  well be a depressed fracture  underneath such a lesion, but with the absence of neurological symptoms  and the lack of a tract  leading from the external wound to the depressed fracture, there would  be few if any cases which  would afterward show either neurological signs or infection of the  fracture and the underlying  cranial structures. In other words, in proper hands, a more  conservative position might be taken  as regards the operating on scalp wounds.
   
    Group    11.- Every case of this group should be explored and  trephined.  Experience with  this hospital confirmed what already was well known, that is, that even  the simplest linear  fracture or even abrasion of the skull may overlie serious intracranial  damage. If the pathway  from the external wound to the fracture is continuous, then infection  will in many cases--even  with the simple depressed fracture without dural penetration-lead to a  meningitis or an abscess in  the contused adjacent cortex.
   
  Group  III.- The majority of cases reported in this group showed only a small  puncture of  the dura or slight laceration. An occasional one, however, had a short  tract of contused tissue.  The question always arises as to whether the best procedure is to close  the dura at once with silk  sutures, thus hoping to avoid infection of the underlying tissues, or  to leave it open, arranging for  drainage. From a study of the cases in this hospital, as well as  experience elsewhere, it seems  that every patient in whom the dura is sutured does badly. There is a  tendency to the damming  back of the infection in the subdural tissues, leading to meningitis or  cortical abscess. Where the  dura has been left open, such infected material evacuates itself  beneath the scalp, and if the scalp  is drained into the dressing no progressive infection arises and the  wound heals with little  reaction. As a general policy it would seem advisable in cases of this  type to leave the dura open  and, in addition, to drain the scalp with a small rubber-tissue wick. A  case of this type is as  follows:
  
  CASE 15.- S. D. Pvt., No. 552003, 38th Inf.,  Co. K. Wounded: October 9, 10 a. m. machine-gun bullet,  which made two holes in his helmet. Unconscious five minutes after  injury. Wound 10 by 2 cm. over the right  parietal eminence, the large diameter being 
 768  
  
  anteposterior. X-ray examination showed metallic dust in the wound.  Shadow suggesting fracture of the inner table.  Admitted, Mobile Hospital No. 6, October 9, 6.30 p. m. A. T. S. given.  Neurological symptoms: Right pupil larger  than the left. Right cremasteric reflex present, more sluggish than  left. Left knee jerk more active than right. Left  Babinski. Pulse 80. Operation: Tripod incision, with wide incision of  wound. Scalp wound did not extend down to  skull, but upon examining skull a line of fracture extending backward  toward the occipital lobe was present, with no  depression of the external plate. Upon opening the skull, two pieces of  internal plate measuring 1½ cm. in diameter  were found pressing deeply against the dura. One of these lay partially  through a small tear in the dura. These were  removed. The exposed dura pulsated and there seemed to be no undue  tension. It was, therefore, not opened further.  The scalp was now closed with S. W. G. sutures. Local anesthesia.  October 11: Wound dressed. Looks all right.  Pupils equal No Babinski. Diminished sensation left hand and left  forearm. Perception of pin prick. Loss of muscle  sense and astereognosis. October 13: Stitches removed. Wound healed.  October 17: Both pupils dilated equally .  React to light. No neurological symptoms. Evacuated sitting. 
  
  This  case was evacuated to Base Hospital No. 56-A. His condition upon  arrival was  good, and from there he left on November 14. Wound healed; no.  symptoms; recommended for  convalescent camp.  
  
  In  some eases, classified as Group III, there was no penetration of dura  from the original  injury, but there were marked neurological signs, and the appearance of  the dura at time of  operation indicated hemorrhage and contusion in the adjacent cortex. In  three such cases the  dura was opened and the damaged tissue beneath evacuated by irrigation  and by having the  patient cough, and the dura subsequently sutured. These cases did very  well. It seems that with a  relatively clean external wound excised thoroughly with a block removal  of the bone, carried out  with the necessary technique, a sufficiently clean operation field can  be obtained, so that the dura  may be safely opened and sutured.  
  
  In  contradistinction to the type of cases referred to above, where the  original injury, has  punctured the dura, the contused cortex beneath the intact dura is  sterile and if the technique is  good, after the evacuation of this contused tissue, the dura may  logically be sutured over what is  a sterile field. Drainage may be advisable down to the dura to take  care of the oozing and any  possible contamination of the scalp incision. A case of this type is as  follows: 
  
  Case 16.- L.F., No. 2255444, 347th Reg.  Machine Gun Bat., Co. D. Wounded: September 29. 4 p. m.  Gunshot, wound head and left buttocks. A. T. S. given. X-ray  examination: Head negative. Admitted to Mobile  Hospital No. 6, October 3, 12 p. m. Wound on vertex of skull lying in  direction of Rolandic fissure, 8 by 1 cm. On  left side. The inne angle of the wound extended 20 mm. to the left of  median line. Neurological examination: Unable  to move ankles and toes, right and left. Right cremasteric sluggish;  left active. Right leg rather spastic; deep reflexes  right leg hyperactive. Sustained right ankle-clonus. Right Babinski.  Operation: Isle-of-Man incision; block removal  of bone. Dura injured but not penetrated. There was evidence of  underlying contusion of the bone. Dura opened just  to the right of the longitudinal sinus, and upon having patient cough a  quantity of softened contused brain substance  and a clot size of the thumb was expressed. This seemed to be in the  leg area. Dura closenl. Scalp wound sutured.  October 11: Convalescence uneventful. Neurological examination shows  equal pupils, the left eve perhaps a shade  smaller. Both react to light and accommodation but right more slowly.  Visual field normal; retina normal. October  24: Patient can move toes and feet of both legs. Motions limited in  power in toe and ankle-joint . Knee motions of  both legs normal. Right ankle-clonus; none on left. Babinski is present  on neither side. Evacuated. 
 769  
   
  This  case is of particular interest from the neurological standpoint,  because the clinical  pictures correspond to the longitudinal sinus syndrome described by  Sargent and Holmes. The  damage to the cortex was so apparent that the dura was incised and the  blood clots evacuated.  The subsequent history showed a very distinct improvement in the  neurological signs.  
  
  Group IV.- The treatment carried out  at this hospital in cases of this group in which there  was extensive damage of the cortex with indriven bone fragments, was  less successful than that  in any other group. There were several factors which accounted for  this. The great majority--one  might, say practically all of these cases--were the result of  tangential  wounds in which the damage to the brain was not only direct from  laceration by the indriven bone, but also in many  cases from the concussion and general commotion of the adjacent area of  the cerebrum. If one  could have a blow of the same intensity delivered without any fracture  of the skull, there would  undoubtedly be severe concussion and in some instances a fatal issue  from the intensity of the  intracranial damage by "commotion"; secondly, it is in these cases that  the pathway of infection  from the scalp to the intracranial contents is most widely open. Almost  without exception, they  arrived with gutter wounds, funnel-shaped; and with cranial contents  extruding and overflowing  the scalp. In such a case-as was the rule at this hospital--if from 24  to 48 hours was taken from the time of the wound to reach the operating  table, there is almost sure to be infection in the  scalp, in the extruding cranial contents and within the cerebrum  itself, about the indriven  fragments of bone. It is, then, nearly as important that this  particular type of cranial injury should  reach the surgeon's hands in a few hours. Unfortunately, the general  idea that all head cases  travel well before operation has led to the opinion that there is no  urgency in forwarding these  cases to their operative destination. 
  
  If  one were fortunate enough to be so situated as to receive these cases  in three or four  hours after injury then any who would die after operation would in any  event have died of the  severity of the intracranial damage. If one waited 10 hours, the  majority perhaps of these could  be ruled out. Their condition would be very apparently moribund, or  they would have begun to improve sufficiently to justify operation. On  the other hand, if one waited longer than 15 hours,  the danger of propagation of infection in the intracranial structures  increases rapidly. It, would  seem, then, that the optimum time for operation, reasoning purely from  the clinical side, would  be between 10 and 15 hours after the injury.  
  
  It  is in this group that the most detailed and careful technique is  necessary. It would  hardly seem necessary to emphasize the fact that the cerebral tissue  must be treated with care,  but from observation of the work done at this hospital bv teams which  had had some  neurological training only two operators were among these teams who had  a proper respect for  the tissues upon which they were working. It is impossible--contrary to  the general opinion-to  train the average surgeon, however good he may be in general work, in  the space of one or two  weeks to the necessary fastidious reflexes which are so essential to  the successful treatment of  these cases. Of six patients evacuated in good
 770 
  
  condition three had been  operated upon by one team, the operator of which was most  conservative in his method of handling the brain tissue.  
  
  It  would seem that greater emphasis should be laid upon the steps  necessary in cleaning  up this type of wound. After the preliminary de bridement of the  superficial structures,  repeated coughing and straining of the patient will, as suggested by  Cushing, evacuate the  contused tract of fragments of bone and sometimes a foreign body,  without any further  manipulation. It is only after this procedure has been carried to the  point where no further results  are obtained that one should introduce the catheter. Often it will be  found if this is done that the  catheter's most important use is as a probe for the discovery of  fragments of bone still remaining  in the tract. Again, it can not be too strongly emphasized that the  catheter in the hands of many  without a wholesome fear of the brain tissue may lead to irreparable  damage. Indeed in some  hands it is as dangerous as the finger and may be thrust very readily  into the ventricle,  converting the chances of recovery from 60 to 70 percent to about 20  percent.  
  
  One  feels very definitely, after an experience with cases of the type and  age received at  this hospital, in which infection of the scalp or its intracranial  contents is very problematical, that  such wounds should be left open for free drainage. It might almost be  stated as an axiom that a  herniating wound is an infected wound and no amount of mechanical  operative manipulation  will control such a herniation. The only possible control is drainage,  which from the time of  operative procedure will in many cases prevent the extension of  infection and sometimes even  the formation of a hernia. Without drainage there would be an initial  herniation and blocking off  of the septic material, encephalitis, and the progressive picture which  is all too familiar to the  cranial surgeon.  
  
  The  dogmatic statement arising early in the war of 1914-1918, that a  cranial wound must  be sutured, arose at least in part from the fact that drainage with  glass or rubber tubes and  dressing of exposed cranial contents with gauze or other adherent  material led to fungus  formation. A quite different treatment, in which the extruding cranial  contents are carefully  protected from compression by a "dough-nut" and from adhesion and the  tearing of the blood  vessels by protective tissues led to the impression that a great number  of herniae will subside in  the course of two weeks, and that a still greater number, if this type  of dressing is used as a  preventive measure, will never occur at all. 
  
  The  following case is typical of those which recovered in Group IV:  
  
  CASE 17.- F.  S., Pvt., 127th Inf., Co. F. G.  S. W. head. Admitted to Mobile Hospital No. 6, October 5.  History: Wounded October 4, 9 a. m., by shrapnel. Remembers  getting hit; was unconscious for a few minutes. Has  suffered since from very severe headaches. Has not vomited. Noticed he saw things double, that he could  not see to  the left, has been drowsy, has been unable to walk alone. Admitted  about 10 p. m. Punctured overtip of left occipital  lobe.

 771 
  
  ceased; temperature 7S, pulse 80; diplopia also present. October  11: Wound dressed. Clean; no  leak; temperature normal. Right hemianopsia possilbly less complete.  October 16: Fundi normal.  Oetober 18: Dressed. Stitches out. Small area of necrosis in center of  wound. No discharge.  Hemianopsia as before. October 20: Dressed. Slight granulation of  wound. Condition good.  October 21: Granulating area practically closed and dry. Wound clean.  Right hemianopsia niow  incoImpletc and improved. Reflexes normal Evacuated.
   
  Group  V.-It is a surprising fact that in this group of cases, where  the  foreign body was  retained within the cranium, the results were distinctly better than in  the preceding group. A  missile striking the skull at an angle, especially after penetrating  the helmet, is frequently  deflected and does not penetrate, but by its implact drives hone  fragments into the cranium over  a large area with great laceration. If, on the other hand, it strikes  at an approximate right angle  and penetrates, especially if it is of small size, the greater part of  the damage is produced by the  missile itself, the number of bone fragments is small, and consequently  the sum total of the  damage done is less than in the tangential blow. Then, too, the  penetrating wound frequently  produces a punctate wound of entrance with infection; this infection,  however, from thescalp  surface is not as rapid as through the gutter-shaped wound of the Group  IV class.
  
  As  regards treatment the same procedures apply as noted under the  preceding group. A  word should be added, however, in respect to the extraction of foreign  bodies. The first reaction  on the part of an inexperienced operator is that every foreign body  should be removed or an  attempt made at its removal. This was the experienee in this hospital.  One should have definitely  in mind the course of the missile, the anatomical structures it has  crossed and their function, and  above all the relation of the tract and the missile to the ventricle.  It is obvious that a tract  crossing the neighborhood of the basal ganglia and the internal  capsules can be probed or  explored with safety in few if any cases. The slight increase in damage  produced by the  exploratory instrument, no matter how careful one is, may lead to  hemorrhage or edemia, or  introduce infection in areas where encephalitis will be at once fatal.  
  
  On  the other hand, where the tract passes through cortical or immediately  subcortical  areas or through the so-called "silent areas," more extensive  exploration can be attempted. The  danger of opening the ventricle is perhaps the greater one and can not  be too strongly  emphasized. It should be constantly reiterated that the opening of the  ventricle changes the  mortality from 30 to 40 percent to 70 to 80 percent at least. The  employment of special localization methods, such as a Hirtz compass, in  the experience gained at this hospital is only a  temptation to excess of exploration, and the same to a lesser degree  may be true of the use of the  magnet. Such procedures in the hands of experienced and conservative  operators in some cases  would be invaluable, but in the hands of the average operator would be  more dangerous than  useful. Illustrative cases of this group are the following:

  The  advantage of such a specialized unit as this may be summarized as  follows: 1.  Refinement of technique, approximating that really necessary to do even  fairly satisfactory work,  is possible. 2. Changes in technique, and the adoption of adjuncts,  such as X ray are rapidly  possible in a group with a centralized control, such as this. 3. The  training of surgical teams, and  the insistence upon the most fastidious technique can be accomplished  readily only in such a  hospital. 4. It is possible to get "team play'" between the

  ophthalmologists,  maxillofacial surgeons, X-ray department, pathologists, etc.,in one  hospital; it  is exceedingly difficult to do so in all of a dozen or more hospitals.
  
  The disadvantages, as they  appear in this experience, were principally those of transportation and  triage. This hospital was  situated at such a distance from the front that during a major portion  of the fighting, cases  reached it upon an average of 36 hours after injury. In addition, there  were too many steps in  transportation; that is, all cases would be evacuated through one and  sometimes through two  hospitals, at which points there would be a delay of sometimes 12 or  even 24 hours. These cases  did not suffer from length of transportation to any great degree, but  they did suffer, as shown by  data, especially those under Group IV, by the prolonging of the  preoperative period, during  which infection was uncontrolled. It should always be stated as a  corollary to the axiom, "Head  cases bear transportation well before operation," that a delay of 24  hours increases the chances of  infection and decreases the chances of survival almost as markedly as  it does in penetrating  wounds of the abdomen. This is shown by the high mortality in Group IV,  where the wounds  were open, cranial contents extruding, and infection had a wide pathway  of entrance, whereas in  the other groups in which the point of penetration was smaller, and the  path of infection more  devious, the mortality was as low, and even lower, than the ideal  figure given in "Instructions to  the Neurological Surgical Teams."
