Lung ultrasound score to determine the effect of fraction inspired oxygen during alveolar recruitment on absorption atelectasis in laparoscopic surgery: a randomized controlled trial.

ABSTRACT:

Background

Although the intraoperative alveolar recruitment maneuver (RM) efficiently treats atelectasis, the effect of FIO₂ on atelectasis during RM is uncertain. We hypothesized that a high FIO₂ (1.0) during RM would lead to a higher degree of postoperative atelectasis without benefiting oxygenation when compared to low FIO₂ (0.4).

Methods

In this randomized controlled trial, patients undergoing elective laparoscopic surgery in the Trendelenburg position were allocated to low- (FIO₂ 0.4, n = 44) and high-FIO₂ (FIO₂ 1.0, n = 46) groups. RM was performed 1-min post tracheal intubation and post changes in supine and Trendelenburg positions during surgery. We set the intraoperative FIO₂ at 0.4 for bot
