Effect of different carbon dioxide pneumoperitoneum pressure on postoperative shoulder pain occurrence following laparoscopic cholecystectomy / 中国普通外科杂志

ABSTRACT

Objective To determine if the carbon dioxide (CO 2) pressure used in laparoscopic cholecystectomy (LC) has any effect on the occurrence of postoperative shoulder pain. Methods One hundred and twenty consecutive patients undergoing LC were prospectively divided into three groups(40 patients in each group): Patients in group A underwent LC with 10 mm Hg of CO 2, those in group B with 12 mm Hg of CO 2, and in group C with 14 mm Hg of CO 2. PaO 2?PaCO 2?pH before and after LC were recorded. Shoulder pain was recorded on a visual analogue pain scale 1,3,6,12,24,48,72,96 h after operation. Results The intraoperative CO 2 consumption was significantly higher in group C (F=11.38,P
