Effect of Propofol Midazolam on Cerebral Oxygenation and Metabolism During Clipping of Ruptured Cerebral Aneurysm

Ruptured Cerebral Aneurysm Clinical Trial

Official title: Cerebral Oxygenation and Metabolism in Patients Undergoing Clipping of Cerebral Aneurysm: A Comparative Study Between Propofol-based Total Intravenous Anesthesia and Sevoflurane-based Inhalational Anesthesia

Status Completed

Clinical Trial Summary

Despite the theoretical benefits of i.v. agents, volatile agents remain popular. In a study comparing desflurane, isoflurane, and sevoflurane in a porcine model of intracranial hypertension, at equipotent doses and normocapnia, cerebral blood flow (CBF) and ICP were least with sevoflurane.

Propofol is the most commonly used intravenous anesthetic. It has many theoretical advantages by reducing cerebral blood volume (CBV) and ICP and preserving both autoregulation and vascular reactivity. Neurosurgical patients anaesthetized with propofol were found to have lower ICP and higher CPP than those anaesthetized with isoflurane or sevoflurane.

The well known pharmacodynamic advantages of intravenous anesthetics may give this group of drugs superior cerebral effects when compared with inhalation anesthetics.

Clinical Trial Description

The aim of this study is to evaluate the cerebral hemodynamics and global cerebral oxygenation as well as the systemic hemodynamic changes using midazolam and propofol as total intravenous anesthetics (TIVA) in comparison with sevoflurane anesthesia in clipping of ruptured cerebral aneurysm. ;
