Low Tidal Volume-Positive End-expiratory Pressure versus High Tidal Volume-Zero Positive End-expiratory Pressure and Postoperative Pulmonary Functions in Robot-assisted Laparoscopic Radical Prostatectomy

Objective: The aim was to compare the effects of low tidal volume (VT) and moderate positive end-expiratory pressure(PEEP) with high tidal volume (VT) and zero end-expiratory pressure(ZEEP), on postoperative pulmonary functions and oxygenation in patients undergoing robot-assisted laparoscopic radical prostatectomy. Subjects and Methods: Forty-four (44) patients were randomized into low VT-PEEP and high VT-ZEEP groups. The patients were ventilated with VT of 6 ml/kg and 8 cmH2O PEEP in low VT-PEEP group and VT of 10 ml/kg and 0 cmH2O PEEP in high VT-ZEEP group. Preoperative and postoperative spirometric measurements were done and chest X-rays were evaluated using radiological atelectasis score(RAS). Statistical signi ficance was at p
