Abstract
A retrospective survey of head injuries in NSW in 1977 and 1978 was conducted by the Trauma Subcommittee of the Neurosurgical Society of Australasia. This paper describes the findings for 129 patients who had more than one significant intracranial haematoma. Overall, the case fatality rate for these patients was 85%. The presence of low or fluctuating blood pressure was associated with a significantly higher mortality than in the rest of the group. Bilateral reacting pupils or an improvement in level of consciousness following decompressive surgery carried a more favourable prognosis. There was 100% fatality if surgery was not carried out or if the bleeding was not found at operation. A subset of patients who died was selected on the basis of a calculated prognostic variable, and compared with a similar subset of survivors. A higher proportion of patients who died had a delay in the provision of definitive treatment and failure to correct shock. This comparison was made on two criteria. Using the first accepted optimal treatment in 1984, nearly all cases were treated suboptimally, as might be expected. Using the second, acceptable treatment in 1977-78, it was calculated that between nine and 12 patients died with MIH in NSW in the 2 years of the survey, whose deaths might have been prevented.
