Time of rehabilitation admission and severity of trauma: effect on brain injury outcome.
Outcome after traumatic brain injury, defined by the Glasgow Outcome Scale (GOS) and length of stay in acute rehabilitation, was measured in 59 patients admitted to an intensive rehabilitation program to examine the effects of severity of the initial brain injury, severity of multiple trauma, and length of stay in the acute care hospital. Severity of initial brain injury, best measured by length of coma, was the most significant predictor of GOS outcome. ⋯ Severity of initial brain injury, length of acute hospitalization, and gender emerged as predictors of length of rehabilitation hospital stay. Although length of acute hospitalization is apparently affected by severity of brain injury, it adds significantly--more than severity of brain injury--to the prediction of length of rehabilitation.

ReviewManagement of head injury. Treatment of abnormal intracranial pressure.
Intracranial hypertension is recognized as a fundamental pathophysiologic process in brain injury. Although the exact pressure level defining intracranial hypertension remains to be firmly established, the majority of evidence available currently suggests that ICP should generally be treated when it exceeds 20 mm Hg. We suggest that lesions in the temporal lobe be treated at 15 mm Hg owing to the special relationship of this region to the brain stem. ⋯ The basic mechanisms of raised ICP are slowly becoming elucidated. Clinical clues with which to subdivide patients with intracranial hypertension are being defined. New agents with efficacy in lowering raised ICP are appearing, and determination of their mechanisms of action may provide insight into the underlying disorder.

ReviewManagement of head injury. Intracranial pressure monitoring.
The role of intracranial pressure monitoring as an adjunct to the clinical examination, CT scanning, and other diagnostic modalities has become increasingly recognized. This article presents a brief overview of the present status of this technique and touches on prospects for further developments.

ReviewNeurophysiologic monitoring of patients with head injuries.
Despite new technologic developments designed to analyze the brain's electrical activity, monitoring the electroencephalogram or evoked potentials has not yet provided important information with regard to acute management of patients with head injury. Measurement of cerebral blood flow as well as jugular oxygen saturation is of more practical importance. Particularly when monitored continuously, these measures can provide useful information about the use of hyperventilation and control of elevated systemic arterial pressure.
