Modification of the Richmond subarachnoid screw for monitoring intracranial pressure. Technical note.
The authors describe a modification of a subarachnoid screw for monitoring intracranial pressure by hydrostatic coupling of the subarachnoid space to an external transducer. The device can be used in both children and adults and features more assured placement of the distal tip, increased stability, and enhanced safety on insertion.
