ObjectiveTo evaluate the efficacy of injecting 1% lignocaine into the subserosal aspect of the cornual end of the fallopian tubes to control post-operative pain after laparoscopic Filshie clip application.DesignA double blind, randomised controlled trial.SettingThe day surgery unit of the Dunedin Public Hospital, Otago, New Zealand.ParticipantsFifty-nine women attending the public hospital requesting sterilisation.InterventionsThe experimental group received an infiltration of 1% lignocaine into the subserosal aspect of the cornual end of the fallopian tubes. The control group received an infiltration of normal saline in the same site.Main Outcome MeasuresThe use of post-operative pethidine and the scores obtained on a modification of the McGill present pain intensity score, a visual analogue scale of present pain, a pain relief score and comparisons of time to first analgesia use.ResultsThe use of pethidine in the experimental group was significantly reduced [P = 0.001] Pain relief scores indicated significant benefit from the intervention. The time to first analgesic use was significantly greater in the experimental group.ConclusionLignocaine infiltration at the cornual end of the fallopian tubes during laparoscopic Filshie clip application is highly effective in producing post-operative pain relief.
