Local Anaesthetic for Transvaginal Egg Collection in IVF - Full Text View

Purpose

The purpose of this study is to see whether injecting local anaesthetic into the vaginal tissues,just prior to transvaginal egg collection,will decrease the amount of pain experienced by women having their eggs collected on an IVF cycle. All women will also receive intravenous sedation as required as well as a sleeping tablet thirty minutes prior to the procedure which is our routine procedure for egg collection.

Arms	Assigned Interventions
Active Comparator: LA Intravaginal and pre-peritoneal injection of 1% lignocaine into each side of the upper vagina under ultrasound guidance immediately prior to ultrasound guided transvaginal oocyte retrieval	Drug: lignocaine 20 mls of 1% lignocaine solution for injection, 10mls into each side of upper vagina, under ultrasound guidance immediately prior to transvaginal oocyte retrieval under ultrasound guidance from each ovary
Placebo Comparator: P Intravaginal saline placebo injection into each side of upper vagina under ultrasound guidance immediately prior to transvaginal oocyte retrieval	Drug: normal saline 20mls of normal saline solution, 10mls injected each side into upper vagina under ultrasound guidance, immediately prior to ultrasound guided transvaginal oocyte retrieval from each ovary

Detailed Description:

Transvaginal oocyte retrieval is the most common method of oocyte collection in IVF cycles. A variety of different methods are used to provide analgesia/anesthesia for oocyte collection. Our unit has always used an oral pre-medication followed by intravenous fentanyl during the procedure but this doesn't seem to provide adequate analgesia for some women. The aim of this study was to compare the addition of intravaginal local anaesthetic injection versus saline placebo to our usual analgesia regime to see whether less intravenous fentanyl was required and whether the women experienced less pain during oocyte collection.
