RESUMEN
PURPOSE: Mastectomy is one of the most painful surgical procedures. Postoperative pain guidelines recommend transcutaneous electrical nerve stimulation (TENS) as a reliable non-pharmacological analgesic method. The aim of this study was to investigate the effects of TENS on postoperative pain and outcomes in patients undergoing modified radical mastectomy (MRM). DESIGN: A single-center, single-blind, prospective, randomized-controlled study. METHODS: This single-center, single-blind, randomized-controlled study included a total of 80 patients who underwent MRM at general surgery clinic of a tertiary center were included. The pain management of the patient outcomes were evaluated using the Turkish Revised American Pain Society Patient Outcome Questionnaire (APS-POQ-R-TR). FINDINGS: The pain levels of the intervention group were lower than the control group. There were significant improvements in the patient outcomes such as mobilization, position, sleep, anxiety, and fear in the intervention group. CONCLUSIONS: Our study results suggest that TENS reduces MRM pain. Thus, TENS can be recommended as a useful analgesic method in MRM.
