Evaluation of Ventilatory Strategies During Laparoscopic Surgery

January 17, 2014 updated by: Emilpaolo Manno, Maria Vittoria Hospital

Re-expansion of Atelectasis During Laparoscopic Surgery. Recruitment Maneuver vs Positive End-expiratory Pressure: a Randomized Study

Atelectasis involving declive areas often occurs during general anesthesia and may persist postoperatively. This phenomenon could be amplified by pneumoperitoneum and Trendelenburg position. Hypothesis: To evaluate whether the shape of the airway pressure-time curve, Stress Index (SI), during constant flow inflation can lead ventilator setting during general anesthesia.
