Aim. The aim of the present study was to investigate the effects of 8 cm H2O of positive end expiratory pressure (PEEP) with pneumoperitoneum (PP) of 14 mmHg on respiratory system mechanics and function in addition to oxygenation during and after laparoscopic cholecystectomy. Methods. In this prospective study, 70 ASA physical status I-II patients undergoing laparoscopic cholecystectomy were randomized equally to ventilate with 8 cm H2O of PEEP (Group 1) or 0 cm H2O of PEEP (Group 2) during PP. We determined tidal volume (VT), peak inspiratory pressure (PIP), mean airway pressure and dynamic pulmonary compliance (Cdyn) in the intraoperative period. Forced expiratory volume in the first second (FEV 1), forced vital capacity (FVC), peak expiratory flow (PEF), the relation of the FEV1 to the FVC (FEV1/ FVC) and forced expiratory flow in the midexpiratory phase (FEF25-75%) were determined by using spirometry before and two hours after surgery. Results. In Group 2, Cdyn was significantly lower compared to Group 1 at measurement times of C-14 and C-20 (P |
