Is transcutaneous electrical nerve stimulation of any value during cervical laser treatment?

A C Crompton et al. Br J Obstet Gynaecol. 1992 Jun.

Abstract

Objective: To assess the value of transcutaneous electrical nerve stimulation (TENS) during cervical laser therapy.

Design: Randomized three arm controlled clinical trial comparing (i) TENS, (ii) local anaesthetic and (iii) TENS plus local anaesthetic (direct infiltration of 2% lignocaine and 0.03 iu/ml octopressin).

Setting: Colposcopy Unit adapted to run randomized trials.

Subjects: 100 women with CIN and no previous experience of cervical surgery.

Main outcome measure: Visual linear analogue pain scores.

Results: The median pain score associated with TENS was greater than the score associated with local anaesthesia (23% compared with 17%; P = 0.1). Combining TENS with local anaesthesia did not further reduce pain scores.

Conclusion: Although there was considerable consumer satisfaction with TENS it provided no additional pain relieving effect in addition to direct infiltration of lignocaine and it is inferior to lignocaine alone. We are unable to advocate the use of TENS for laser treatment of the cervix.
