Positive end-expiratory pressure (PEEP) during anaesthesia for the prevention of mortality and postoperative pulmonary complications

Effect of Intraoperative PEEP Application on Colonic Anastomoses Healing: An Experimental Animal Study

“…Still, the literature suggests that it should be initiated immediately after or up to the 30th minute following induction and then continued throughout the operation. 2,33 In our study, the mean duration of the surgery was 55 6 4.59 minutes for each rabbit. PEEP was initiated at induction and was continued throughout the surgery.…”

“…Several studies measured atelectasis using computed tomography in the postoperative period and concluded that both the extent and the frequency of the atelectasis are smaller in the PEEP groups compared with the ZEEP groups. 2,24 It is well known that systemic hypoxia has a direct impact on collagen synthesis and deposition, and thus disturbs the healing of the anastomosis. 3 If PEEP is able to improve the postoperative oxygenation, its influence on the healing of the anastomosis must then be investigated.…”

The Influence of Positive End-Expiratory Pressure on Leakage and Oxygenation Using a Laryngeal Mask Airway: A Randomized Trial

“…[26][27][28] A Cochrane systematic review and meta-analysis assessed that the application of PEEP during general anesthesia increases the arterial partial pressure of oxygen (Pao 2 )/Fio 2 ratio and reduces the incidence of postoperative atelectasis. 29 However, the effects of PEEP on gas exchange during general anesthesia are mixed. 30,31 Whether PEEP improves gas exchange during positive pressure ventilation with an LMA mask is also unclear.…”

Effect of positive end expiratory pressure on atelectasis in patients undergoing major upper abdominal surgery under general anaesthesia: A lung ultrasonography study

“…Multiple studies (Imberger et al 2010, Östberg et al 2018, Pereira et al 2018) comparing Zero PEEP (ZEEP) versus PEEP which used CT scan for detecting atelectasis found that PEEP significantly reduced atelectasis.…”
