Abstract

Intracranial pressure was monitored in 23 patients, either who exhibited an increase in pressure or who were considered at risk for the developement of intracranial hypertention. The intracranial pressure was measured while the patient was in the position from supine to 50 degree of head elevation. The intracranial pressure was decreased during head elevation, but 8 cases(34.8%) were not changed. The maximal cerebral perfusion pressure was seen at 50 degree of head elevation(52.2%), next 30 degree(21.7%) and 40 degree(7.4%) in orders. The changes of vital sign were not significant during head elevation. To control the intracranial pressure, the patient who were managed in the position of 30degrees and 50degrees head elevation showed most effective cerebral perfusion pressure without any significant changes of the vital sign and central venous pressure.
