Effectiveness of Heat Application on Gastric Variables Among Patients With Nasogastric Tube Feeding Admitted in the Intensive Care Units at a Selected Hospital: A Randomized Control Trial.

Background: Heat application, a nonpharmacological intervention, can relieve abdominal distension (AD), high stomach residual volume, and other specific gastrointestinal (GI) functions. It promotes peristaltic movement, which reduces intra-abdominal pressure and aids in the nutritional transition through the GI tract. It has also been demonstrated to be a noninvasive, safe, effective, and side-effect-free approach without needing medication.
