Researchers aim to evaluate impact of transcutaneous electric nerve stimulator on the incidence of postoperative diaphragmatic dysfunction in patients living with obesity undergoing bariatric surgery

Bariatric surgery is associated with several postoperative consequences, including challenging pain control, respiratory complications, and diaphragmatic dysfunction. Postoperative diaphragmatic dysfunction is defined as a diaphragmatic excursion of less than 10 mm. There is substantial evidence that diaphragmatic ultrasound provides a reliable and accurate assessment of diaphragmatic function in both intensive care unit and perioperative settings.

The present randomized controlled trial aims to evaluate the influence of transcutaneous electrical nerve stimulation on postoperative diaphragmatic dysfunction in morbidly obese patients undergoing bariatric surgery.

Inclusion Criteria:

• Body mass index > 40 kg/m2
• ASA II

Exclusion Criteria:

• Limited diaphragmatic ultrasound views
• Patient with pulmonary diseases (COPD, bronchial asthma, and interstitial fibrosis)
• Patient refusal
