Surgical therapy for intracranial extracerebral haemorrhages is one of the oldest surgical techniques. The low mortality and morbidity in recent years have come about through of the emergency service, modern neurosurgical techniques, widespread use of the CT scanner, and adequate intensive care. The treatment target in the case of head injuries is to provide the optimal milieu for recovery from the primary injury and to prevent secondary damage to the brain. ⋯ Twist drill evacuation of the fluid (= chronic haematoma) in local anaesthesia is now accepted as the treatment of choice. An extradural haematoma is a potentially lethal lesion with a mortality rate of 5%. Emergency surgical intervention is appropriate before neurological signs appear.

ReviewFatal cerebral gunshot wounds: factors influencing organ donation.
Patients with clinical brain death following head injury are important potential cadaveric organ donors. We analyzed our series of cranial gunshot wounds with particular attention to the frequency and patterns of organ donation after fatal injuries. Sixty-six patients with gunshot wounds to the head, including 59 with intracranial involvement (43 male, average age 26 years) were seen during a 4-year period. ⋯ Of the 39 patients who died, 28 met standard criteria for brain death, and nine of these went on to organ procurement. Thirteen families refused donation, and six patients were not harvested for reasons including old age, pregnancy, suspicion of AIDS, coroner refusal, and failure to pursue consent. Principles essential to maximal organ retrieval include: 1) Recognition that patients suffering cerebral gunshot wounds represent potential organ donors and that certain factors are predictive of mortality; 2) Critical care/trauma team approach with standardized management and timely declaration of brain death; 3) Early search for family members and prompt notification of organ procurement agencies; 4) Sensitivity to cultural issues influencing donation; and 5) Programs to increase public awareness of organ donation.

The officially appointed external expert needs a precise documentation of the initial clinical findings and the findings at follow-up of the patient with craniocerebral trauma. The next step in preparation of the expert report consists in a pathophysiological and a neurological examination, including CT scan and EEG repeated at intervals; a stable condition can be expected after 1-2 years. In the case of reversible closed head syndrome (brain concussion) the expert should certify a disability for about 6 months; a degree of 20% for over 3 months should not be certified unless there are massive vegetative signs and symptoms. ⋯ Adults who are unconscious for up to 5 days can be expected to make a complete recovery, while a longer duration of coma and more advanced age are associated with a worse outcome. The degree of functional impairment is thus important in the expert's decision on the level of disability. A flow chart is presented for guidance in the preparation of expert reports.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative StudyA comparison of the Glasgow Coma Scale and the Swedish Reaction Level Scale.
The Glasgow Coma Scale (GCS) and the Swedish Reaction Level Scale (RLS85), two level-of-consciousness scales used in the assessment of patients with head injury, were compared in a prospective study of 239 patients admitted to a regional head injury unit over a 4-month period. Assessments were made by nine staff members ranging from house officer to registrar, after briefing about the two scales. Data were also collected on age, nature of injuries, surgical treatment, and condition at discharge or transfer using the Glasgow Outcome Scale. ⋯ The RLS85 was reported by all users to be simpler to use than the GCS, but the latter is much more widespread in use. Both scales function well in cases of severe and minor head injury, but have weaknesses when defining moderate head injury. Level-of-consciousness scales are only an aid to assessment and the final choice between the two scales must remain a matter of personal or departmental preference.
