Treatment for severe head injury.

Difficulties in establishing the value of certain treatments for head injury are reviewed. An analysis of 1000 severely head injured patients, managed by varying methods in three different countries, showed that certain treatments were more often used in the most severely injured patients. Even when the severity of injury was taken account of, it appeared that the use of steroids and tracheostomy did not affect outcome; but that patients undergoing mechanical ventilation had outcomes which were worse than expected. The value of treatments proposed for severe head injury needs rigorous scrutiny.

Head injuries in three Scottish neurosurgical units. Scottish head injury management study.

The organisation of care for patients with head injuries in Scotland was investigated by studying retrospectively 785 patients admitted in 1974 and 1975 to neurosurgical units in Glasgow, Aberdeen, and Dundee. The reasons for the injuries and the patients' clinical conditions were similar in each unit. The referral practices at the hospitals containing the units were compared and found to be different from that of the unit in Edinburgh. It is concluded that patients in the Glasgow, Aberdeen, and Dundee units, which operate a similar policy for head-injured patients, are in general similar. Transferring to a neurosurgical unit only selected patients rather than all patients with head injuries is safe practice only if policies are agreed with primary surgeons and patients can be transferred without delay.

How many specialists?

The need for specialists cannot be adequately assessed on the basis of current practice and an estimated case-load (based on prevalence/population ratio). Specialists should declare which patients can or cannot be expected to benefit from their treatment, and they should consider the consequences of underprovision of specialist services. Specialists should also decide how much of what they normally do might equally well be carried out by generalists using the knowledge of specialists. Only then can the appropriate level of provision for various specialties be assessed, and effective deployment of the resources provided ensured.

Computerised tomography after recent severe head injury in patients without acute intracranial haematoma.

Sixty patients with severe head injury who did not have an acute intracranial haematoma on CAT scanning are reviewed. The scans are correlated with the level of consciousness at the time of scanning and with the outcome six months after injury. The initial scan was interpreted as being normal in 38% of the cases. In the remainder the most common abnormalities were small ventricles and areas of mixed increased and decreased density interpreted as contusions. All the patients with small ventricles were under 20 years of age. Postmortem examinations were undertaken on 15 of the 19 fatal cases. There was evidence of a high intracranial pressure in 12, cerebral contusions were absent or minimal in 10, there was diffuse immediate impact damage to white matter in six, and there was moderate or severe hypoxic damage in four.

Prognosis of patients with severe head injury.

The relationship between clinical features of brain dysfunction in the first week after severe head injury and outcome 6 months later has been analyzed for 1000 patients. Depth of coma, pupil reaction, eye movements, and motor response pattern, and patient age prove to be the most reliable predictors. The degree of brain dysfunction changes markedly soon after injury, and more reliable predictions of outcome result when assessment is based on the best level of functioning recorded in each early epoch. Predictions based on very early assessment are, therefore, often unduly pessimistic. Individual predictions of outcome, based on a large data bank, provide a powerful tool for assessing the relative efficacy of alternative treatments.
