Summary
Neuroendoscopic procedures can increase intracranial pressure due to irrigation fluid. Monitoring intracranial pressure during these procedures is crucial to assess and manage potential adverse effects on cerebral perfusion pressure.
Area of Science:
- Neurosurgery
- Medical Devices
- Physiology
Background:
- Intracranial pressure monitoring is not standard during neuroendoscopic procedures.
- Irrigation without drainage during endoscopy can lead to increased intracranial pressure.
Purpose of the Study:
- To measure and monitor intracranial pressure changes during the irrigation phase of neuroendoscopic procedures.
- To assess the impact of irrigation on intracranial pressure and cerebral perfusion pressure.
Main Methods:
- Intracranial pressure was monitored in 13 patients using a Codman catheter.
- Standardized anesthesia was used, with recordings of heart rate, mean arterial pressure, intracranial pressure, and cerebral perfusion pressure.
- Measurements were taken at baseline and during the irrigation phase.
Main Results:
- Mean arterial pressure increased by 7 mmHg during irrigation (P=0.02).
- Intracranial pressure significantly increased by an average of 34 mmHg (P<0.001).
- Cerebral perfusion pressure decreased by an average of 26 mmHg (P<0.001), with four episodes of ICP >25 mmHg per patient.
Conclusions:
- Neuroendoscopic irrigation significantly increases intracranial pressure and decreases cerebral perfusion pressure.
- Routine intracranial pressure monitoring during neuroendoscopic procedures is recommended.
- Monitoring allows for assessment of adverse effects and informed clinical management.
