Reletex Reliefband plus ERAS to reduce nausea after robotic sleeve gastrectomy

Use of Transcutaneous Electrical Nerve Stimulation Device, Reletex Reliefband to Decrease Postoperative Nausea and Vomiting in the Bariatric Surgical Patient

Not applicable Interventional University of Pennsylvania · NCT07063979

This trial will test whether wearing the Reletex Reliefband in addition to standard ERAS care can reduce nausea and vomiting in adults having robotic sleeve gastrectomy.

What this trial studies

Adults scheduled for robotic sleeve gastrectomy at a single center will be assigned to wear either an active Reletex Reliefband or a visually identical sham device starting at the end of surgery. The band is turned on in the PACU at a low setting and settings are titrated using the Post Operative Nausea and Vomiting (PONV) Impact Scale with repeated checks in PACU and on the surgical floor; device battery limitations require removal and replacement per protocol around 12 hours. The study compares rates of PONV and need for additional antiemetics within the first 24 postoperative hours to see if the non-drug device improves comfort, mobility, and recovery when added to current care.

Who should consider this trial

Good fit: Adults 18–75 years old with BMI ≥35 who are eligible for and scheduled to undergo a robotic sleeve gastrectomy and can provide informed consent are the intended participants.

Not a fit: Patients with gastroparesis, pregnancy, cardiac pacemakers/defibrillators or intrathecal pumps, recent tobacco use, or known allergy to conductivity gel (and those not undergoing robotic sleeve gastrectomy) are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, this could reduce postoperative nausea and vomiting, lower the need for antiemetic drugs and their side effects, and help patients mobilize and recover sooner.

How similar studies have performed: Prior small studies of wrist nerve-stimulation or acupressure-like devices for PONV have shown mixed but sometimes promising reductions in nausea, though evidence specific to bariatric sleeve patients is limited.

Eligibility criteria

Inclusion Criteria:

* Adults 18-75 years of age
* BMI 35 or greater

Exclusion Criteria:

* A diagnosis of gastroparesis
* Pregnancy
* Presence of a cardiac pacemaker/defibrillator or intrathecal pump
