Abstract

OBJECTIVE
Measurement of intracranial pressure(ICP) is important in patients at risk of raised ICP. To evaluate the usefulness of measuring epidural pressure measurements for the estimation of intracranial pressure, we studied the relationship between epidural pressure and ventricular pressure. PATIENTS AND METHODS: From Nov. '97 to Jul. '98, 10 patients of extraventricular drainage(Group A) and 12 patients of decompressive craniectomy(Group B) are included in this study. Simultaneous recording of intracranial pressure (ICP) from an air-pouch epidural pressure monitoring system and a ventricular catheter was compared. RESULTS: The epidural pressure group(Group A) showed marked high epidural pressure(32.6+/-13.4mmHg) compared with those of intraventricular pressure, but in decompressive craniectomy group(Group B) shows nearly the same values(2.1+/-6.9mmHg). CONCLUSIONS: On the basis of the available comparison between these two methods of measuring intracranial pressure, in the light of the data we had established and the importance of ICP monitoring in neurosurgical critical care, intradural monitoring technique appears to be our measuring method of choice.
