Objective:
To 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.
Design:
A double blind, randomised controlled trial.
Setting:
The day surgery unit of the Dunedin Public Hospital, Otago, New Zealand.
Participants:
Fifty-nine women attending the public hospital requesting sterilisation.
Interventions:
The 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 Measures:
The 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.
Results:
The 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.
Conclusion:
Lignocaine infiltration at the cornual end of the fallopian tubes during laparoscopic Filshie clip application is highly effective in producing post-operative pain relief.
