Effects of Alveolar Recruitment Strategies on Arterial Oxygenation and Postoperative Inflammatory Response During Laparoscopic Bariatric Surgery: A Randomised Control Trial.

even though the advancement of ambulatory bariatric surgeries, yet the precise spot of recruitment manoeuvres as a secure and efficient approach to enhance the respiratory efficacy of obese patients is still obscured. Previous research have extensively focused their attention towards alveolar recruitment with various positive end-expiratory pressure (PEEP) levels to alleviate anaesthesia induced pulmonary collapse and enhance arterial oxygenation. Patients and methods: a prospective randomized study involved 60 adult obese patients (18-65 years), with American Society of Anaesthesiologists physical Status classification 1-2, enrolled in 2 groups; Group S: received protective lung strategy with recruitment manoeuvre (RM) every 30 minutes and steady PEEP (10) cm H2o in between RM till end of surgery. Group D: received protective lung strategy with recruitment manoeuvre (RM) every 30 minutes and decreasing PEEP (15, 10, and 5) cm H20 (10 minutes for each level) in between RM till end of surgery.
