1. Management of Head Injuries

2. Dealing with the life saving priorities: (ABC)
Protection of the AIRWAY. (Cleaning and putting airway tube or endotracheal tube).
Maintenance of adequate BREATHING.Prevention of Hypoventilation.
CIRCULATION: arrest of haemorrhage,correction of shock, and maintaining adequate blood pressure The presence of shock in a patient with a head injury is most likely due to internal haemorrhage in the thorax or abdomen.
Care must be taken to secure the neck and spine (by putting collar around the neck

3. Oropharyngeal Airway

4. Endotracheal tube

5. Secure the neck (Rigid Collar)

6. II. Initial evaluation and examination
A. Important points in the History B. Initial examination C. Indications for admission

7. A. Important points in the History
Cause, Circumstance and Mechanism of injury.
Period of loss of consciousness.
Period of post-traumatic amnesia.
Presence of headache and vomiting.
Level of consciousness at scene and on transfer.
Evidence of seizures.
Pre-existing medical conditions.
Medications (especially anticoagulants)

8. B. Initial examination
Vital signs.
Scalp.
Skull.
Level of Consciousness: The Glasgow Coma Score
Pupils: size and reaction to light:
Immediately dilated pupil : direct trauma of the orbit or the oculomotor nerve.
Pupil dilated later : lateralization due to supratentorial haematoma.

10. B. Initial examination
6. Lateralising signs: Hemiplegia in the acute phase is more likely due to primary cerebral injury rather than due to a compressing intracranial haematoma.
7. Signs of base of skull fracture.
8. Full neurological examination: tone, power, sensation and reflexes.
9. Limbs: for any fracture or vascular injury.
10. Chest: examine for fractured ribs, pneumothorax or haemothorax.
11. Abdomen: examine for internal haemorrhage or peritonitis.
12. Back: for the possibility of fractures or dislocations of spines.

13. C. Indications for admission to the hospital
depression of level of consciousness (esp.> 5 minutes).
Skull fracture.
Focal neurological sign.
Persistent and progresive headache or vomiting.
Patients who are difficult to assess - for example, those who are also intoxicated.
Concomitant diseases or medications that pose increased risk (for example, coagulopathies and anticoagulants).
Absence of responsible relatives who can observe the patient for the first 24 hours.

14. b. Cervical spinal x-ray c. CT scan
III. INVESTIGATIONS
a. Plain skull x-ray:
b. Cervical spinal x-ray
c. CT scan

15. a. Plain skull x-ray
1. Can demonstrate the site and type of a skull fracture.
2. A foreign body can also be seen.

16. Skull Fracture

18. Indications for skull x-ray in head injury
Impaired consciousness or neurological signs.
History of loss of consciousness, amnesia, or fits.
High speed injury or suspected penetrating injury.
Scalp laceration to bone, large haematoma, or suspected fracture on palpation.
Persisting vomiting or headache.
Loss of cerebrospinal fluid or blood from ear or nose.
Difficulty in assessing the patient (children, drug or alcohol intoxication).

19. b. Cervical spinal x-ray
To exclude fracture or dislocation of spines

20. Done immediately and sometimes need to be repeated.
c. CT scan
Done immediately and sometimes need to be repeated.

21. Indications for immediate CT scan in head injury
Glasgow Coma Score (GCS) <13 at any point.
Progressive headache
Focal neurological deficit.
depressed, or basal skull fracture.
Seizure.
Repeated vomiting

22. Indications for immediate CT scan in head injury
7. Age more than 65.
8. Coagulopathy (e.g. on warfarin).
9. Dangerous mechanism of injury
10. Antegrade amnesia more than 30 minutes (CT within 8 hours).

23. Indications to repeat CT scanning
Delayed deterioration in the mental state.
A persistent rise in intracranial pressure (ICP).
Failure to improve over 24 hours.

24. IV. Continuing Care and Observations
The aims of conservative treatment are:
To give the patient the maximum care until spontaneous recovery occurs.
To detect and prevent complications that may need surgical interference.

25. a. Continuous care Attention to the airway.
A Foley’s catheter: to facilitate the nursing care and to estimate the urine output.
Frequent change of posture to avoid bed sores.
Physiotherapy of the joints and massage to the muscles.
Intravenous isotonic maintenance fluids should be given (crystalloids) until nasogastric feeding.
Nasogastric tube feeding.
Measures to decrease the intracranial pressure, pay good attention to the following points:
Mannitol after excluding EDH and patient should have normal renal function..
Steroids in severe head injury are associated with increased mortality and should not be used.

26. b. Repeated observations
Level of consciousness using the Glasgow Coma Scale.
Vital signs Pulse, blood pressure, and temperature and UOP.
Respiration.
Pupils.
5. Reflexes.

27. c. Causes of deterioration of the patient:
BRAIN OEDEMA .
Airway obstruction and/or hypoventilation leading to brain swelling .
Intracranial haematoma.
FEVER due to respiratory infection or meningitis.
Overtransfusion by hypotonic fluid or dehydration.
Epilepsy
