Randomized Controlled Trial
Transcutaneous Electric Nerve Stimulation Reduces Acute Postoperative Pain and Analgesic Use After Open Inguinal Hernia Surgery: A Randomized, Double-Blind, Placebo-Controlled Trial.
In this randomized, double-blind, placebo-controlled trial, we evaluated the role of transcutaneous electrical nerve stimulation (TENS) in the multimodal treatment (nonopioid analgesics and kinesiotherapy) of postoperative pain following open inguinal hernia repair. In total, 80 males participants with elective primary unilateral hernia Lichtenstein repair were randomly allocated to receive TENS or a placebo-TENS procedure. The TENS group received local and segmental conventional TENS on the first and second postoperative days. ⋯ The study was registered in the database of clinicaltrials.gov (register number NCT03739060). PERSPECTIVE: This article presents TENS as a safe and effective nonpharmacologic intervention to reduce postoperative pain after open inguinal hernia repair. TENS could be used in daily practice as part of a multimodal postoperative pain treatment, especially for patients suffering from hyperalgesia.
