Effect of transcutaneous electrical nerve stimulation on quality of recovery and pain after abdominal hysterectomy

OpenAlex English

Background and Aims: Transcutaneous electrical nerve stimulation (TENS) is a noninvasive complementary therapy for postoperative pain management. The effect of TENS on quality of recovery (QoR) and pain treatment in the early postoperative period is not well documented. The aim of this study was to evaluate the effect of TENS on postoperative QoR and pain in patients who had undergone a total abdominal hysterectomy with bilateral salpingo-oophorectomy (TAH + BSO). Material and Methods: Fifty-two patients were randomized into two groups: control (sham TENS treatment) and TENS (TENS treatment). QoR, dynamic pain, and static pain were evaluated after surgery. Results: The QoR score was significantly higher in the TENS group as compared with that in the control group ( P = 0.029). Pain scores during coughing (dynamic pain) were significantly less in TENS group compared to control group ( P <0.001). However, there was no between-group difference in pain scores at rest (static pain) or total analgesic consumption ( P = 0.63 or P = 0.83, respectively). Conclusion: TENS may be a valuable tool to improve patients' QoR and dynamic pain scores after TAH + BSO.
