Abstract

Background

Laparoscopic surgery is the main trend method in a variety of surgical fields. Post-operative shoulder pain remains a bothersome issue although many surgical techniques have been applied to minimize it. A simple novel approach to reduce shoulder pain without adverse effects during and after laparoscopic surgery is desired.

Methods

This prospective randomized controlled study was conducted to enroll a total of 140 patients to evaluate the efficacy of low flow rate (1 L/min) for induction followed by high flow rate (10 L/min) for maintaining 12 mmHg pneumoperitoneum (group A, n = 70) during laparoscopic cholecystectomy (LC), compared to the continuous high flow rate group (group B, n = 70) in postoperative shoulder pain and other clinical features. The 10-visual analog scale (VAS) was applied for the severity of shoulder pain and scores were obtained at 1, 6, 12, 24, and 48 h after LC.

Results

There was no obvious difference in baseline characteristics as well as operative time, occurrence of bradycardia, or hospital stay between groups. The incidence of shoulder pain was not significantly different (group A 45.7% vs group B 48.6%, p = 0.866). However, the patients in group A with shoulder pain reported significantly less pain scores (p < 0.001) at 12 and 24 h after surgery, compared with those in group B.

Conclusions

Applying the strategy of low flow rate to induce pneumoperitoneum followed by high flow rate to maintain the pressure provides advantages to reduce the severity of shoulder pain for patients who underwent LC and then experienced shoulder pain.
