Summary

Elective laparoscopic cholecystectomy may lead to perioperative atelectasis due to pneumoperitoneum-related diaphragmatic elevation and impaired respiratory mechanics. Lung ultrasound (LUS) provides a noninvasive bedside method for evaluating perioperative aeration loss. This prospective randomized controlled study aims to compare the effects of low-pressure (10 mmHg) and standard-pressure (14 mmHg) pneumoperitoneum on perioperative atelectasis assessed by LUS in patients undergoing laparoscopic cholecystectomy under general anesthesia. Changes in LUS scores, respiratory mechanics, oxygenation, and postoperative clinical outcomes will also be evaluated.

Conditions

  • Atelectasis
  • Perioperative Complication
  • Pneumoperitoneum

Interventions

DIAGNOSTIC_TEST

10 mmHg Pneumoperitoneum

Laparoscopic cholecystectomy will be performed with intra-abdominal pressure maintained at 10 mmHg during insufflation. Standard anesthesia and surgical protocols will be followed.

DIAGNOSTIC_TEST

14 mmHg Pneumoperitoneum

Laparoscopic cholecystectomy will be performed with intra-abdominal pressure maintained at 14 mmHg during insufflation. Standard anesthesia and surgical protocols will be followed.
