Effects of Video-Assisted Surgery on Ventilatory Parameters

Effects of Pneumoperitoneum on Ventilatory Parameters in Patients Undergoing Video-assisted Surgery

The study investigates the effects of induced pneumoperitoneum during surgery on ventilatory parameters including peak inspiratory pressure, lung compliance, end-tidal CO2 at specific time-points: after induction of anaesthesia, after induction of surgery, one-hour and two-hours during surgery, end of surgery.

The effects of pneumoperitoneum are compared between two groups of patients: patients undergoing laparoscopic surgery and patients undergoing robotic-assisted surgery. No intervention was performed in this study and the decision for type of surgery performed was made by the attending surgeon prior to study inclusion

Inclusion Criteria:

• patients who underwent video-assisted surgery by either classic laparoscopy or robotic-assisted surgery.

Exclusion Criteria:

• refusal to participate
• conversion of surgery to laparotomy
• need of vasopressure support
• preoperative severe respiratory dysfunction
