Background: Preincisional and postoperative Transcutaneous Electrical Nerve Stimulation (TENS) has shown an opioid sparing effect in the treatment of postoperative pain after major spine surgery. The aim of this study was to test the effect of TENS applied intraoperatively on intraoperative demand for fentanyl. Methods: Forty-eight patients scheduled for dorsal lumbar fusion were enrolled and divided into two groups by random numbers. Group A received TENS preoperatively, intra-operatively and postoperatively. Group B received this treatment pre- and postoperatively only. Fentanyl was given during surgery if systolic blood pressure and or heart rate increased 15% over baseline level. Bispectral index (BIS) was maintained between 40 and 50. The total amount of fentanyl administered intra-operatively was recorded. Physician-determined analgesics were given postoperatively to achieve a v.. View More»
