Hot Water Foot Bath for Pain and Gas Relief After Laparoscopic Cholecystectomy

The Effect of Hot Water Foot Bath on Pain and Gas Release After Laparoscopic Cholecystectomy: A Randomised Controlled Trial

This study investigates the effects of a hot foot bath on postoperative pain and time to first gas release in patients undergoing laparoscopic cholecystectomy. The intervention is a non-pharmacological supportive method applied during the early postoperative period. Participants will be randomly assigned to either intervention or control groups. No FDA-regulated drug or device is involved.

This randomised controlled clinical trial aims to evaluate the effects of hot foot bath therapy on postoperative pain and time to first flatus in patients undergoing laparoscopic cholecystectomy. The hot water foot bath is a non-pharmacological, supportive intervention to be administered at 3 hours postoperatively after patients have regained consciousness and are clinically stable.

Participants will be randomly divided into two groups: the intervention group will receive a 20-minute foot bath at a water temperature of 41°C, while the control group will receive standard postoperative care without a foot bath. The primary outcomes include pain level assessed using the Numerical Rating Scale (NRS) and time to first flatus recorded in hours postoperatively.

In addition to these primary outcomes, the study will also collect data through a two-part questionnaire. The first part will include questions regarding the sociodemographic and medical history of the patients, such as age, gender, marital status, education level, income level, presence of chronic diseases, previous surgical history, preoperative bowel movement frequency and duration of surgery. The second part focuses on indicators of postoperative recovery, including time to surgery, time to postoperative ward arrival, time to first oral intake, time to first mobilisation, total mobilisation time in the first 8 hours, time to first gas passage and type of analgesic administered.

This study does not involve any drug or device regulated by the U.S. Food and Drug Administration (FDA). Ethical approval was obtained from the Fenerbahçe University Non-Interventional Research Ethics Committee. Institutional permission was also granted in writing by Istanbul University-Cerrahpaşa Faculty of Medicine Hospital, where the clinical study will be conducted. No funding was received from Fenerbahçe University or any other organization.
