A new miniaturized system for monitoring the epidural pressure in children and adults.
A new miniaturized epidural pressure transducing system for monitoring intracranial pressure (ICP) has been developed. The system is of the as yet smallest known dimensions. The transducer is implanted automatically coplanar to the dura via a burr hole of 4 mm diameter in the conscious patient without special surgical equipment. Application is possible in adults, children and infants. We have achieved a maximal resolution of 10(-3) mm of Hg. At a full scale range of 100 mm of Hg the zero-point drift is less than 1 mm of Hg/24 h.
