Abstract
Subdural pressure (SDP) was measured in 25 patients with head injury and intracerebral hematoma, by a subtemporaly placed Gaeltec catheter-tip pressure transducer. The SDP was well correlated with the ventricular fluid pressure. Correct and prompt responses to SDP and pulse wave were observed during head elevation, hyperventilation, and intravascular administration of the osmo-diuretic agents.
This transducer seemed to be beneficial in measuring SDP of various portions, and calibrating zero-point repeatedly during measurement. As intracranial pressure (ICP) is said to be variable in the different intracranial portions, the importance of measuring subtemporal ICP of the ipsilateral hemisphere to the lesion is discussed.
