Effect of PEEP on regional ventilation during laparoscopic surgery monitored by electrical impedance tomography.

Abstract

BACKGROUND Anesthesia per se and pneumoperitoneum during laparoscopic surgery lead to atelectasis and impairment of oxygenation. We hypothesized that a ventilation with positive end-expiratory pressure (PEEP) during general anesthesia and laparoscopic surgery leads to a more homogeneous ventilation distribution as determined by electrical impedance… (More)
