Esophageal Pressure Versus Gas Exchange to Set PEEP During Intraoperative Ventilation.

Background: Pneumoperitoneum and Trendelenburg position affect respiratory system mechanics and oxygenation during elective pelvic robotic surgery. The primary aim of this randomized pilot study was to compare the effects of a conventional low tidal volume ventilation with PEEP guided by gas exchange (V) versus low tidal volume ventilation tailoring PEEP according to esophageal pressure (V) on oxygenation and respiratory mechanics during elective pelvic robotic surgery.

Methods: This study was conducted in a single-center tertiary hospital between September 2017 and January 2019.
