Evaluation of a subdural pressure transducer. Technical note.

✓ A simple practical method for monitoring intracranial pressure has been developed; it is based on a diaphragm-type, full-bridge, absolute-pressure gauge that is stable. The transducer is calibrated to absolute pressure at body temperature. It is placed in a trephine opening where it is in contact with the subdural space. The transducer is contained in a self-threading case that will fit in a 14 mm trephine opening. Its use in 30 patients with acute head injury is reported.
