The Effect of Positive End Expiratory Pressure on Reduction of Respiratory Complications during and after the Surgery in Patients undergoing Laparoscopic Bariatric Surgery

This study aimed to determine the effect of positive end expiratory pressure (PEEP) on reduction of respiratory complications during and after the surgery in patients undergoing laparoscopic bariatric surgery.

In a clinical trial study performed in Alzahra hospital, Isfahan, Iran, during 2018-19, 54 patients with severe obesity were selected and allocated in two groups of laparoscopic bariatric surgery with and without PEEP (10 cmH2</sub>O). The incidence of respiratory complications and hemodynamic status of patients before, during, and after surgery were evaluated and compared.

The use of PEEP in laparoscopic bariatric surgery decreased the time of hospitalization in intensive care unit (ICU) and general ward, increased oxygenation saturation during surgery and recovery, and improved the number of breathing. The use of PEEP was helpful in preventing respiratory distress, too.

 According to the results of this study, it can be concluded that PEEP, as a medical aid, can be useful in reducing respiratory complications after laparoscopic bariatric surgery.
