Minimal and normal-flow general anesthesia in patients undergoing surgery in prone position: ımpact on hemodynamics and regional cerebral oxygenation.

ABSTRACT:

Purpose

In this study, the aim to assess the combined effects of prone-positioning (PP) and minimal-flow (MF) general anesthesia on regional cerebral oxygenation (RCO) and systemic hemodynamics.

Methods

This is a randomized prospective study aiming to evaluate changes in cerebral oxygenation and hemodynamic parameters in MF systemic anesthesia in patients undergoing surgery in PP. Patients were randomized to MF or normal-flow (NF) anesthesia. In the operating room, pulse rate, mean arterial pressure (MAP), peripheral hemoglobin oxygen saturation (spO2), and right- and left-side RCO (assessed by near-infrared spectroscopy, NIRS) were measured perioperatively.

Results

Overall, 46 patients were included (24 in the MF group and 22 in the NF group). The amount of anestheti
