The hypothesis that cerebral arteriovenous difference of oxygen content (AVDO2) can be used to predict cerebral blood flow (CBF) was tested in patients who were comatose due to head injury, subarachnoid hemorrhage, or cerebrovascular disease. In 51 patients CBF was measured daily for 3 to 5 days, and in 49 patients CBF was measured every 8 hours for 5 to 10(More)
The authors report 144 cases in which acute subdural hematomas resulting from closed head injury were surgically treated. The mortality rate was 48% for those treated within 24 hours of injury and 45% for those treated within 72 hours. Patients under 10 years of age had a 33% mortality, while 69% of those over 60 years died. In the first 6 years of the(More)
Intracranial compliance, as estimated from a computerized frequency analysis of the intracranial pressure (ICP) waveform, was continuously monitored during the acute postinjury phase in 55 head-injured patients. In previous studies, the high-frequency centroid (HFC), which was defined as the power-weighted average frequency within the 4- to 15-Hz band of(More)
