Summary

Laparoscopic colorectal surgery is associated with an increased risk of intraoperative atelectasis due to pneumoperitoneum, Trendelenburg positioning, and prolonged anesthesia duration. Atelectasis developing during surgery may persist into the postoperative period and contribute to postoperative pulmonary complications. Automated lung recruitment maneuvers delivered by modern anesthesia ventilators may offer a standardized method to improve lung aeration and reduce atelectasis. This prospective, randomized, single-center controlled trial aims to evaluate the effect of automated intraoperative lung recruitment maneuvers on atelectasis detected by lung ultrasonography in patients undergoing elective major laparoscopic colorectal cancer surgery. Adult patients will be randomized to receive either automated lung recruitment maneuvers or standard mechanical ventilation without recruitment. Lung ultrasonography will be used to assess atelectasis at predefined perioperative time points. The primary outcome is the incidence of atelectasis detected by lung ultrasound, and secondary outcomes include postoperative pulmonary complications, length of intensive care unit stay, length of hospital stay, and perioperative hemodynamic instability.

Conditions

  • Atelectasis
  • Postoperative Pulmonary Complications (PPCs)

Interventions

PROCEDURE

Automated Intraoperative Lung Recruitment Maneuvers

Automated lung recruitment maneuvers will be performed intraoperatively using the anesthesia ventilator in pressure-controlled ventilation mode according to a standardized protocol.
