Lung Recruitment and PEEP Effects on Intracranial Pressure in Cranial Surgery

Sponsor: University of Chile

View on ClinicalTrials.gov

Summary

High positive end-expiratory pressure (PEEP) levels required to achieve clinical benefits may increase ICP and reduce cerebral perfusion pressure (CPP) in patients at risk of intracranial hypertension. However, individualizing ventilation parameters is essential for each patient. Among protective ventilation strategies, PEEP is key to preventing alveolar collapse. The PEEP level that minimizes alveolar collapse while avoiding overdistension of the pulmonary parenchyma is known as the Best PEEP. This study aims to evaluate the application of Best PEEP in cranial neurosurgery.

PROCEDURE

Subdural pressure measurement

Subdural intracranial pressure (SDIP) will observed during an alveolar recruitment maneuver and best PEEP titatration. SDIP will be measured while mechanical ventilation is maintained using the identified best PEEP.
