Randomized Controlled Trial
High and low frequency TENS reduce postoperative pain intensity after laparoscopic tubal ligation: a randomized controlled trial.
Transcutaneous electrical nerve stimulation (TENS) is an effective adjunctive therapy for postoperative pain; however, effects of different frequencies of stimulation have not been systematically investigated. Laparoscopic sterilization (LS) causes significant pain in the early postoperative period and requires substantial postoperative medication. Therefore, we studied the effects of TENS on postoperative pain after LS through placement of Yoon fallopian rings in a prospective, randomized, double-blinded, and placebo-controlled study. ⋯ We recommend regular use of multimodal therapy with TENS and analgesic drugs after LS with placement of Yoon rings.
