Pressure Support versus Spontaneous Ventilation during Anesthetic Emergence —Effect on Postoperative Atelectasis: A Randomized Controlled Trial

ConclusionsThe incidence of postoperative atelectasis was lower in patients undergoing either laparoscopic colectomy or robot-assisted prostatectomy who received pressure support ventilation during emergence from general anesthesia compared to those receiving intermittent manual assistance.Editor ’s PerspectiveWhat We Already Know about This TopicPressure support ventilation modalities are now standard on newer anesthesia machines and are commonly used during emergence from anesthesiaTheir benefits in preventing postoperative atelectasis have not been well studiedWhat This Article Tells Us That Is NewA randomized trial in patients undergoing laparoscopic colectomy or robot-assisted prostatectomy compared pressure support ventilation to spontaneous ventilation with intermittent manual assistance during anesthetic emergenceThe outcome was atelectasis in the postanesthesia recovery unit, using lung ultrasoundThe incidence of atelectasis was significantly lower and the Pao2 was significantly higher with pressure support ventilation; however, in the 48-h postoperative observation period, the incidence of oxygen saturation measured by pulse oximetry less than 92% was not different between groups
