PROTOCOLS FOR THE MANAGEMENT OF HEAD INJURIES
This protocol is designed for use with the general protocol for management
of trauma patients (and presumes that it has been followed in relation to
airway and haemodynamic management). It presumes a brisk clinical examination
and appropriate history. If operation is required for other reasons, head
injury management may become more difficult.
Consult the duty neurosurgeon.
A. GCS 8 OR LESS.
Action: Call Neurosurgeon.
- Sedate, paralyse and intubate patient

- Peritoneal lavage all patients in this category.
B. GCS 9 -14 WITH FOCAL SIGNS.

- Half hourly neuro observations.
- If decreased GCS go to A above.
- Urgent CT scan ~,vit:n 2 hours.
C. GCS 9 -14 WITHOUT FOCAL SIGNS BUT FRACTURE ON SKULL X-RAY.
Action:
- Half hourly neuro observation for 6 hours.

- At 24 hours if GCS 15 and if home environment supervised, discharge with head injury card.
D. GCS 9 -14 WITHOUT FOCAL SIGNS, NO FRACTURE ON SKULL X-RAY
