Summary

Postoperative gastric distension is a common gastrointestinal complication after cardiac surgery and may delay recovery, prolong intensive care unit (ICU) stay, and reduce patient comfort. Anti-bloating patches are widely used in clinical practice to promote gastrointestinal function recovery; however, high-quality evidence regarding their effectiveness in cardiac surgical patients remains limited.

This randomized controlled trial aims to evaluate the efficacy and safety of an anti-bloating patch in reducing postoperative gastric distension after cardiac surgery. Adult patients undergoing cardiac surgery will be randomly assigned to receive either standard perioperative care alone or standard perioperative care plus anti-bloating patch therapy. Gastric bubble area will be quantitatively measured using chest radiographs and image analysis software.

The primary outcome is the change in gastric bubble area on postoperative day 1 compared with baseline. Secondary outcomes include gastric bubble area on postoperative day 1, percentage change in gastric bubble area, abdominal distension score, time to first flatus, time to first bowel movement, gastric drainage volume, time to oral feeding, ICU length of stay, postoperative hospital length of stay, and patch-related adverse events.

The results of this study may provide evidence for the use of anti-bloating patches as an adjunctive intervention to enhance postoperative gastrointestinal recovery in patients undergoing cardiac surgery.
