Anti-Bloating Patch for Postoperative Gastric Distension After Cardiac Surgery (ABP-CS)
Efficacy of an Anti-Bloating Patch for Postoperative Gastric Distension After Cardiac Surgery: A Randomized Controlled Trial Using Quantitative Gastric Bubble Imaging Analysis
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.

Detaljerad beskrivning
Background Postoperative gastrointestinal dysfunction is frequently observed after cardiac surgery because of surgical stress, cardiopulmonary bypass, anesthesia, opioid administration, and prolonged bed rest. Gastric distension may contribute to patient discomfort, delayed gastrointestinal recovery, prolonged hospitalization, and increased healthcare utilization. Although anti-bloating patches are commonly used as a complementary intervention in perioperative care, evidence regarding their efficacy in cardiac surgery patients remains insufficient.
Objective To evaluate the clinical efficacy and safety of anti-bloating patch therapy for postoperative gastric distension in patients undergoing cardiac surgery and to establish an objective imaging-based method for quantitative assessment of gastric bubble area.
Methods This is a prospective, randomized, controlled, single-center clinical trial. A total of 150 adult patients undergoing elective cardiac surgery will be enrolled and randomly assigned in a 1:1 ratio to either an anti-bloating patch group or a control group.
Participants in the control group will receive standard perioperative management. Participants in the intervention group will receive anti-bloating patch therapy in addition to standard perioperative management.
Chest radiographs obtained on the day of surgery and on postoperative day 1 will be analyzed using ImageJ software. Gastric bubble area will be independently measured by trained investigators according to a predefined protocol
