Abstract
To investigate the effect of two methods on postoperative shoulder pain following laparoscopic cholecystectomy (LC). A total of 99 patients undergoing LC were prospectively divided into three groups (33 patients in each group): Patients in group A underwent LC were control group, those in group B were inserted negative pressure drainage tube under the right inferior phrenic after LC, and patients in group C accepted warm and normal saline flush during operation under the right inferior phrenic. Shoulder pain occurrence and shoulder pain levels (visual analogue pain scale-VAS) were recorded on 1, 3, 6, 24, 48, 72 h after operation. Postoperative shoulder pain occurrence was significantly higher in group A (14/33) than those in group B (6/33) and group C (1/33), and group C had the best effect (χ(2)=2.733, P=0.004) among the 3 groups. For shoulder pain levels, same result was achieved with group C had the best effect (P<0.05). Warm and normal saline flush during operation under the right inferior phrenic could help to obviously reduce the occurrence of post LC shoulder pain probably by blocking some mechanisms causing postoperative shoulder pain after LC.
