The Influence of Basic Ventilation Strategies and Anesthetic Techniques on Cerebral Oxygenation in the Beach Chair Position

University of Michigan·interventional·Posted Feb 17, 2012·Updated Apr 6, 2022

In Brief

A clinical study evaluating Inspired oxygen fraction / end tidal carbon dioxide for Stroke. Completed, enrolled 67 participants across 1 site.

Detailed Summary

The seated or "beach chair" position during surgery and general anesthesia decreases brain oxygen levels and can result in stroke. As such, poor neurological outcome following beach chair positioning is a growing concern. In the proposed study the investigators test the hypothesis that changes in ventilation strategy and anesthetic technique can affect cerebral oxygenation in anesthetized patients in the beach chair position.

Interventions

Inspired oxygen fraction / end tidal carbon dioxideother

Following induction of anesthesia, FIO2 and minute ventilation will be sequentially adjusted to achieve: 1. FIO2 30% (70% nitrogen), PETCO2 30mmHg - supine position. 2. FIO2 30% (70% nitrogen), PETCO2 30mmHg - beach chair position. 3. FIO2 100%, PETCO2 30mmHg - beach chair position. 4. FIO2 100%, PETCO2 45mmHg - beach chair position. 5. FIO2 30% (70% nitrogen), PETCO2 30mmHg - beach chair position.
