Using Ambu Aura-i Laryngeal Mask Airway in Cranial Surgery

Cairo University120 enrolled

Overview

the investigators hypothesize that Ambu aura-i LMA can be used safely in patients undergoing craniotomies and are effective in reducing the incidence of emergence hypertension.

In this study the investigators want to assess the safety of using SGA devices in cranial surgery and comparing the effect of these devices with ETT regarding hemodynamics stability throughout the procedure and intracranial tension.
