Intraoperative Intracranial Pressure Monitoring as an Intraoperative Guide During Operations for Relieving Elevated Intracranial Pressure.

Background: Intracranial pressure (ICP) is a well-established measure in managing not only traumatic brain injury but also nontraumatic intracranial bleeding or edema. When ICP increases despite nursing or medical management, ICP may be reduced via surgical measures. Deciding whether to perform a craniotomy vs. craniectomy (whether the bone flap is replaced or not, respectively) is commonly made intraoperatively following preoperative planning. While ICP monitoring (ICPm) is standard pre- and postoperatively, its intraoperative utility remains understudied.
Methods: We conducted a study utilizing prospectively gathered and retrospectively analyzed data from 25 traumatic brain injury surgical decompression cases at a single center. All cases had intraoperative ICPm throughout surgery.
Results: Our findings indicate that ICPm significantly influenced real-time intraoperative decision-making, diverging from preoperative.
Conclusions: These results bring forward the potential pivotal role of intraoperative ICPm in guiding surgical strategies for elevated ICP, suggesting a novel data-driven approach to intraoperative management of decompression surgery.
