Contribution of raised ICP and hypotension to CPP reduction in severe brain injury: correlation to outcome
The aim of this study was to determine to what degree hypotension and ICP contribute to the reduction of cerebral perfusion pressure (CPP), particularly in light of the shift in emphasis to CPP management by t...

Mortality from traumatic brain injury
It is the general sense that mortality has been decreasing in recent years compared to earlier studies described by the NIH traumatic coma data bank. We studied mortality during the period of 1984 to 1996 to d...
