Effect of Optimized PEEP on Mechanical Ventilation During Robot Assisted Laparoscopic Prostatectomy

Application of Individualized Positive End-expiratory Pressure Using Electrical Impedance Tomography (EIT) in Patients Undergoing Robot Assisted Laparoscopic Prostatectomy : a Randomized Controlled Study

About This Trial

Steep trendelenburg posture or pneumoperitoneum for surgery causes ventilation problems during surgery, so finding a way to overcome is a challenging task for anesthesiologists. In this study, for patients undergoing robot assisted laparoscopic prostatectomy under general anesthesia, anesthesia is going to perform by applying conventional positive end-expiratory pressure (PEEP 5cmH2O) or individually determined positive end-expiratory pressure values for each patient using electrical impedance tomography. We plan to compare intraoperative ventilation through arterial blood gas analysis to find out the way to improve intraoperative ventilation.

Treatments Being Tested

DEVICE

conventional PEEP

Maintain positive end expiratory pressure at 5 cmH2O throughout the surgery.

DEVICE

optimized PEEP

Immediately after induction of anesthesia, the patient remains unapplied to PEEP. After pneumoperitoneum + Trendelenburg posture, an appropriate PEEP value is derived using electrical impedance tomography (airtom®). And then derived value ( = optimized PEEP value) is applied until the end of the operation.
