Answer 1a
Answer 1b
• Head injury is defined as blunt &/or penetrating injury to the head (above the neck) &/or brain due to external force* with temporary or permanent impairment in brain function which may or may not result in underlying structural changes in the brain.
*The external forces may include any of the following events: ▫ the head being struck by an object▫ the head striking an object▫ the brain undergoing an acceleration/deceleration movement
without direct external trauma to the head▫ a foreign body penetrating the brain▫ forces generated from events such as blast or explosion

Answer 6
• The score is the cumulative sum of the scale in each component.
• The levels of head injury severity are classified as:
24
Management at KK (2nd visit)• Patient was attended immediately:
▫ Vital signs & GCS scoring done▫ O2 via oxygen mask given▫ IVD normal saline commenced▫ Cervical collar to immobilise cervical spine put on
• Patient was sent to the radiology unit for skull X-ray in view of occipital haematoma & it was done within half an hour.
• He was then immediately sent to the nearby hospital & accompanied by a medical officer.
Q7. Is skull X-ray indicated in this patient?
25
Answer 7
• The plain skull x-ray is ineffective screening tool in predicting ICH in MHI with a mean sensitivity of 50.0% (ranges from 13.0% to 75.0%) & a mean specificity of 97.0% (ranges from 91.0% to 99.5%).55
Thus,1. The patient should be sent immediately to hospital without
wasting time doing skull X-ray.2. The skull X-ray has no value on further management.

Answer 11
34
What are the pitfalls in the management
of this patient?
Patient should be admitted in the first scene as…1. Patient was 68 years old (>65 years) & had history
of falling from a motorbike.
2. The history of medication for heart disease e.g. aspirin & warfarin was not elicited in the first visit
3. The social history was not properly taken• Patient was staying alone - nobody to supervise him• Patient had difficulty to read without a reading glasses
4. Verbal explanation regarding discharge advicewas not given• Patient misunderstood that he should come to clinic only
when headache is severe
35
What are the pitfalls in the
management of this patient?-2
• In those aged ≥60 years, irrespective of motor scale component of GCS, total GCS score & head AIS score, is an independent risk factor for the mortality.13
• Patients with pre-injury use of antiplatelet agents (e.g. clopidogrel & aspirin) are at an increased risk for mortality with blunt traumatic ICH.76

Answer 1
44
Answer 1
• The purpose of triage is to ensure the right patient receives appropriate timely treatment in the right place before he/she deteriorates.34
• A systematic method ensures quick work flow process.34
34. Pearson WS, et al. Prehospital Emergency Care. 2012;16(3):323- 328
45
Answer 1
46
History (cont.)
• Patient was triaged as Green & attended by a medical officer.
• On examination:• GCS 15/15, BP 180/90 mmHg, HR 65, RR 16• L/W over right temporal parietal region (6 x 1 x 0.5) cm
• Management:• T&S• Allow discharge home with cap. mefenamic acid 500
mg PRN
Q2. Is the management adequate? Documentation?
47
Issues:1. Not following 4-step triage algorithm
(co-morbidities & age 65 year old)
2. GCS 15/15 (was documentation sufficient?)
3. BP 180/90 mmHg (any action or treatment required?)
4. L/W at right temporal parietal region of (6 x 1 x 0.5) cm in dimension (any underlying skull fracture?)
5. Discharge home (any care giver?)
48
Answer 2. Management Issues
49
• MHI is in danger of being underdiagnosed in ED.
• A study of patients who had a HI suggested that patients with a low risk of dying i.e. patients with MHI are at the greatest risk of inadequate diagnosis & treatment.
Answer 2. Underdiagnosis of MHI
in ED
50
51
Answer 3. Performing GCS
Answer 3. Documentation of GCS
• Documentation of GCS has 3 parts
1. What is the individual score?
2. Explanation (what did you see?)
3. What is the total score ?
• Example:
E2 eye open to pain, V3 response with sound,
M5 localising pain
GCS 10/15
52
History (cont.)
• Further history from neighbour:
▫ Patient stays alone & has history of DM, MR secondary to rheumatic heart disease & hypertension.
▫ He is on atenolol, glibenclamide & aspirin.
Q4. State your triage category & give your
reasons.
53
Answer 4
54
Triage category:
Yellow Zone
Reasons:1. Older adults
• Risk of injury/death increases after age 65
2. Anticoagulation & bleeding risk
55
Answer 5
• Initial management of patients with HI should be
performed according to primary survey of
trauma patients as recommended by Advanced
Trauma Life Support guidelines:• Airway patency & cervical spine protection
• Breathing
• Circulation & haemorrhage control
• Disability
• Exposure

SAFE TRANSFER
Dr. Tony Yong Yee Khong
General Surgeon, Hospital Sultanah Aminah, Johor
Dr. Mohd. Sofan Zenian
Neurosurgeon, Hospital Queen Elizabeth, Sabah
Dr. Zarina Yakof
Radiologist, Hospital Sungai Buloh, Selangor
78
History
• An 18-years-old motorcyclist, with h/o bikeskidded & fell, & was brought to hospital lessthan half an hour later▫ helmet was not buckled, sustained brief LOC, could
obey simple command, opened eye spontaneously &disorientated towards place
• He had scalp laceration on right frontal region,which was sutured.
• Vital signs - BP 122/80, PR 76• Primary survey showed no life threatening
injuries.
79
Question 1
• What is the initial GCS?
• What other important history should be taken/clinical signs to be noted?
• Does he need an immediate CT scan on presentation?
80
Answer 1• Initial GCS - 14 (E4V4M6)
• Medical/drug history whether he is on antiplatelet/anticoagulant.
• Whether he has been vomiting repeatedly or has other signs of increase ICP.
• Assess that he did not have focal neurological deficit, including cranial nerve deficit & no signs of base of skull fracture.
• No he does not need an immediate CT scan.• Based on CCHTR
▫ he needs to be observed until 2 hours post-injury
▫ if GCS is still <15 for head CT
81
Answer 1
82
History (cont.)
• He was seen in a district hospital without CT scan.
• GCS was still 14/15 at 2 hours post-injury.
• A CT head was indicated based on CCTHR
Q2. What should the attending doctor do?
83
Answer 2
• The doctor should call up the neurosurgical/surgical doctor of the receiving hospital with CT & neurosurgical/surgical service to transfer the patient with hospital ambulance & escorted by a doctor/paramedic.
84
History (cont.)
• This patient with GCS 14/15 had been put on cervical collar since pre-hospital management. Neck tenderness could not be elicited on examination.
Q3. Should you image the cervical spine?
What imaging modality would you
choose?
85
Answer 3
• Cervical collar should be kept because cervical injury cannot be cleared without a full GCS. In this case, since there is an indication for CT head, CT cervical is the imaging modality of choice.
86
History (cont.)
• On arrival to hospital with CT, BP dropped to 80/40 mm Hg with PR 110 just before head CT.
• Abdomen was soft, non tender.
• FAST scan revealed positive free fluid.
• Patient did not respond to resuscitation.
• GCS dropped to 10/15.
Q4. What should you do?
87
Answer 4
• Proceed to laparotomy
• CT scan can be performed later.
• CT scan brain/cervical should be done immediately after all source of life threatening bleed has been addressed & patient adequately resuscitated.
88
History (cont.)
• CT brain showed a frontoparietal SDH (thickness 1 cm) with midline shift.
• Definite neurosurgical intervention is required.
• While waiting for transfer, the staff nurse noticed patient’s pupils were unequal (Rt: 2 mm & reactive, Lt: 4 mm & sluggish to light).
• BP remained stable & no signs of Cushing’s reflex.
Q5. What should be done while
waiting transfer?
89
Answer 5
90
91
Answer 6
• Safe transfer practice include:▫ Ensure haemodynamic optimisation
▫ Secure ongoing bleeding prior to transfer
▫ Intubation
▫ Cervical immobilisation
▫ Necessary investigation results
▫ Transfer team should be trained in neuro-trauma management
▫ Reliable communication equipment
▫ Complete transfer checklist for neurosurgical patients
92
93
Answer 7• Transfer monitoring will include pupil size & reaction to
light, cardiac monitoring, BP, pulse oximetry, capnography (if available) ± urine output.
• Targeted parameters:▫ MAP >80 mmHg, PaO2 >97.5 mmHg, PaCO2 35 to 40 mmHg,
SpO2 > 90%
94
95
Answer 8
• Effective communication between referring hospital & neurosurgical centre plays very important role in managing this patient:▫ Allows accurate & reliable information to be conveyed,
& patient worsening clinical condition continuously updated during transfer
▫ Minimises the transit time in ED▫ Allows anaesthetist & OT to be ready & prepared
earlier▫ Allows operation to be executed ASAP once patient
reach the neurosurgical centre

management?a. Skull x-ray (KIV discharge)
b. CT Scan brain (KIV discharge)
c. Admission with or without imaging
d. No imaging
e. ……?
103
• Skull X-ray in a patient with HI on antiplatelet therapy▫ A normal skull x-ray does not exclude ICH & may miss
a fracture.
104
Answer 1. Pitfall 1
Answer 1. Pitfall 2• CT scan in a patient with injury on antiplatelet
therapy▫ Risk factors for urgent scan
Age >65 years old
A history of bleeding/clotting disorder or on anticoagulant &/or antiplatelet (Algorithm 3)
105
History (cont.)
• CT scan brain showed small punctate haemorrhage. Othwersie rest of the findings were normal.
• The patient has a good caregiver, stays 5 minute drive from the hospital with transportation available.
Q2. Do you admit or discharge the
patient?
106
Answer 2
107
History (cont.)
• He was referred to the neurosurgeon & physician for further input & management.
• Ix reviewed:▫ Hb 12 gm/dL, platelet 250,000, PT - 12 secs, PTT 0 -
35, INR - 1.2
• Attending doctor ordered:▫ Continued antiplatelet
▫ Allowed discharge
Q3. What are your comments?
108
Answer 3. Pitfall 3
109
• To continue or withhold antiplatelet therapy in a patient with HI on antiplatelet therapy▫ Physician advised to continue.
• Patients with pre-injury use of antiplatelet agents (e.g. clopidogrel & aspirin) are at an increased risk for mortality with blunt traumatic ICH.76
• Achieving rapid control of haemorrhage is important as the haemorrhagic expansion in traumatic ICH occurs within the first 24 hours after injury77 & is an independent predictor of mortality.78
• Conclusion:▫ Antiplatelet need to be withold if any abnormal CT findings
present.

History (cont.)
• Attending doctor ordered:▫ Withold antiplatelet
▫ To transfuse 4 units of platelets & discharge after platelets transfusion
Q4. What are your comments?
110
Answer 4. Pitfall 4
• Transfusion of platelet concentrates in a patient with HI on antiplatelet therapy.▫ Attending doctor asked to transfuse platelets.
• Platelet transfusion in adults with pre-injury aspirin & traumatic ICH showed inadequate evidence to support the routine use of platelet transfusion in the ED. There was higher mortality among these patients.80
80. Nishijima DK, et al. J Trauma Acute Care Surg. 2012;72(6):1658-1663
111
History (cont.)
• No bed available in ward. Patient was observed in ED.
Q5. How long should the patient be
observed?
112
Answer 5.Pitfall 5
• Duration of observation in ED of patient with HI on antiplatelet therapy.▫ Patients with MHI (GCS 15), >65 years old, on low
dose aspirin with systolic BP <150 mmHg & presenting with initial negative primary head CT, should have a routine repeat head CT within 12 - 24 hours to accurately identify HI or such patients should be subjected to a prolonged hospital observation for at least 48 hours.45
45. Tauber M, et al. J Trauma. 2009 ;67(3):521-5
113
114
Answer 6. Pitfall 6
115
• Discharge criteria in a patient with HI on antiplatelet therapy.
• Antiplatelet therapy has to be sorted out.• Brain CT imaging has to be done.• Adequate observation in hospital.• Presence of responsible adult to monitor at home.
• Discharge instructions to patients & care giver should highlight the following alarming features:99
▫ GCS <15 (unable to open eye spontaneously, disorientated or unable to obey command)
▫ vomiting
▫ headache
▫ amnesia
▫ seizure
▫ neurological deficit 99. Fung M, et al. Brain Inj. 2006;20(9):889-894
History (cont.)
• If the same patient came in to hospital, had a drop of GCS & a positive Brain CT finding of a ICH requiring surgery.
Q7. What should you do?
116
Answer 7
• Antiplatelet therapy would have to be stopped.
• Transfusion of platelets pre-operative procedure should commence.
• Further ordering of platelets in OT.
