Summary

Robotic prostate surgery is commonly performed under general anesthesia with carbon dioxide pneumoperitoneum and steep Trendelenburg positioning. These conditions may reduce lung volumes, impair respiratory mechanics, and increase the risk of atelectasis and postoperative pulmonary complications. Recruitment maneuvers combined with individualized positive end-expiratory pressure may improve intraoperative oxygenation and lung compliance; however, the optimal timing of recruitment maneuver application in robotic prostate surgery remains unclear.

This prospective randomized study aims to compare the effects of recruitment maneuver timing on postoperative pulmonary complications in adult patients undergoing elective robotic prostate surgery. Participants will be randomized into two groups. In the Supine Recruitment Group, the recruitment maneuver will be performed before carbon dioxide insufflation while the patient is in the supine position, followed by individualized PEEP determination. In the Trendelenburg Recruitment Group, the recruitment maneuver will be performed after pneumoperitoneum and Trendelenburg positioning, followed by individualized PEEP determination. Patients will be evaluated for postoperative pulmonary complications up to postoperative 72 hours or until discharge, whichever occurs first.

  • Urologic Surgical Procedures
  • Postoperative Pulmonary Complications (PPCs)
  • Pulmonary Atelectasis
  • Postoperative Complications

Interventions

PROCEDURE

Recruitment maneuver after insufflation and Trendelenburg positioning

A lung recruitment maneuver will be applied after pneumoperitoneum and Trendelenburg positioning, followed by individualized PEEP determination using decremental PEEP titration.

PROCEDURE

Recruitment maneuver in the supine position

The recruitment maneuver will be performed while the patient is in the supine position, before pneumoperitoneum insufflation and Trendelenburg positioning during robotic prostate surgery. The maneuver will be applied according to the predefined intraoperative ventilation protocol to improve alveolar recruitment and reduce postoperative pulmonary complications.
