Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Using TENS to treat pain after abortion

    Researchers from Sahlgrenska University Hospital/Östra, in Göteborg, Sweden compared high-frequency, high-intensity transcutaneous electrical nerve stimulation (TENS) vs intravenous conventional pharmacological treatment after surgical abortion.

    First, the details

    • 200 women who underwent surgical abortion and reported a visual analogue scale (VAS) pain score of at least 3 were randomly assigned to a treatment group.
    • TENS treatment was given with a stimulus intensity between 20 and 60 mA during 1 minute and repeated once if insufficient pain relief (VAS at least 3)
    • A maximum dose of 100 μg fentanyl (Sublimaze) given IV.

    And, the results.

    • There was no difference between groups in pain relief upon discharge from the recovery ward.
    • Patients in the TENS group spent less time (44 minutes) in the recovery ward than the fentanyl group (62 minutes).
    • The number of patients who needed additional analgesics in the recovery ward was comparable in both groups, as was the VAS pain score upon leaving the hospital.

    The bottom line?

    The authors concluded, “These results suggest that the pain-relieving effect of TENS seems to be comparable to conventional pharmacological treatment with IV opioids.”

    TENS was no different from fentanyl except in 1 outcome — time ‘till discharge from the recovery room – which, in the absence of blinding the nursing staff to the treatment, is a suspect difference.

    It would be interesting to survey the staff’s thoughts on the comparative convenience of TENS vs fentanyl, and measure safety.
