Alveolar Recruitment in Obese Patients in Major Gynaecological Cancer Surgery

In the gynaecological oncology clinic of our hospital, open major surgeries for endometrial or ovarian cancer are performed very frequently. In these surgeries, the abdomen is open to the operating theatre environment and the lithotomy and trendelenburg position may have negative consequences on the respiratory system in patients. Intraoperative lung protective ventilation strategies are recommended to reduce postoperative pulmonary complications. In the lung protective ventilation strategy, positive end-expiratory pressure is recommended in addition to 6-8 ml/kg tidal volume according to ideal body weight. In addition, alveolar recruitment strategy can be applied. For this purpose, the investigators planned to evaluate the effect of alveolar recruitment strategy on postoperative pulmonary complications in patients who underwent lung protective ventilation in major open gynaecooncological surgeries. Our secondary aim was to evaluate perioperative haemodynamics, respiratory mechanics, inpatient length of stay.
