The Impact of Incentive Spirometry on Shoulder Tip Pain in Laparoscopic Cholecystectomy: A Randomized Clinical Trial.

Abstract

BACKGROUND\nShoulder pain is among the early postlaparoscopic symptoms related to carbon dioxide used for pneumoperitoneum, which remains in the abdominal cavity. Therefore, incentive spirometry (IS) is a novel technique to alleviate this pain following laparoscopic cholecystectomy (LC). The present study was designed to investigate if the use of IS after LC would relieve shoulder tip pain, and determine the amount of postoperative opioid analgesics utilized.\n\n\nMATERIALS AND METHODS\nThis randomized clinical trial was conducted on patients who were clinically diagnosed with cholecystitis, and underwent LC. Accordingly, group I patients (n=42) received IS (including 10 deep breaths with a spirometer in sitting or semisitting positions) in full consciousness every 2 hours starting at 2 hours after surgery, but group II patients (n=42) did not have respiratory physiotherapy. The postoperative shoulder pain after the surgery was further evaluated by a numerical rating scale (NRS).\n\n\nRESULTS\nAt 4, 8, 12, 24, and 48 hours following LC, the NRS pain scores significantly reduced in group I compared with group II. In addition, the results of the repeated measures analysis of variance indicated significantly lower NRS pain scores within the first 48 hours after LC in group I compared with group II. Consequently, the study findings showed a significantly higher percentage of cases in group II, requiring postoperative analgesics, in comparison with group I.\n\n\nCONCLUSIONS\nIS decreased the severity of shoulder tip pain after LC with no complications. Thus, IS may be considered as a viable alternative to other laparoscopic interventions. However, still further studies are necessary to evaluate its efficacy compared with other techniques.
