PAIN MANAGEMENT(2020)
摘要
Aim:To determine whether transcutaneous electrical nerve stimulation (TENS) is more efficient than placebo TENS and control groups for pain relief.Design:Randomized, single-blinded, placebo-controlled trial. Setting & participants: A total of 78 adults with postoperative pain, after cholecystectomy, at the University Hospital. They were randomized into active TENS, placebo TENS and control.Intervention:A total of 30-min interventions applied in the first 24 h after the surgery.Outcome:Pain intensity.Results:Pain significantly decreased for both TENS, however the active TENS was better. A decrease of 2 points or more on the visual analog scale for 53.8% active TENS and 11.5% placebo.Conclusion:There was a greater reduction in pain of important clinical relevance in the active TENS group. Clinical Trial registration: Brazilian Clinical Trial (REBEC): RBR-6cgx2k.
