Abstract
An increase in intracranial pressure (ICP) during induction of general anesthesia is potentially hazardous in patients with cerebral pathology. When the intracranial compliance curve is at the inflection point, a small increase in intracranial volume will cause a disproportionate rise in ICP, thus reducing cerebral perfusion 1. Elevation of systemic blood pressure and subsequent increase in ICP during rigid laryngoscopy for tracheal intubation may occur in patients with intracranial pathology 2. We describe a patient undergoing craniotomy for resection of a posterior fossa tumor, in whom the laryngeal mask airway (LMA) was used. The ICP changes were monitored continuously during LMA insertion and tracheal intubation.
