Purpose:
Lung-recruitment maneuvers (LRM) have been shown to reduce postoperative pain after laparoscopic surgery. This study aimed to investigate the association of LRM with the incidence of shoulder pain after laparoscopic cholecystectomy.
Methods:
A randomized controlled study was conducted with 110 patients undergoing elective laparoscopic cholecystectomy from July 2022 to March 2023. Participants were randomized to receive either routine exsufflation or LRM at pneumoperitoneum release. The postoperative shoulder pain and abdominal pain were assessed at 1, 4, 6, 12, and 24 h after surgery using a numeric rating scale. Analgesic consumption and postoperative nausea or vomiting (PONV) were evaluated during the first 24 h after surgery.
Results:
The incidence of shoulder pain during the first 24 h after surgery was significantly lower in the LRM group compared to the control group (26.9 vs. 59.3%; P = 0.001). The median [interquartile range] score of worst shoulder pain was significantly lower compared to the control group (3 [2-3] vs 4 [3-5.5]; P = 0.003). Participants in the LRM group showed reduced abdominal pain at rest at 4 and 24 h after surgery, and experienced significantly lower intensities of abdominal pain during mobilization at all time points over 24 h after surgery. There were no significant differences in opioid consumption or the incidence of PONV between the groups.
Conclusions:
LRM reduces both the incidence and intensity of shoulder pain during 24 h after laparoscopic cholecystectomy. Additionally, LRM was associated with reduced intensity of abdominal pain during mobilization over the study period.
