About this study

Official title: A Randomised Controlled Trial of Intravaginal Lignocaine Injection Versus Placebo for Analgesia During Oocyte Recovery in an IVF Cycle

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • lignocaineDrug

    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

  • normal salineDrug

    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

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Total dose of iv fentanyl used during oocyte collection

    Measured: Length of oocyte collection (minutes)

Secondary outcomes (11)
  1. Pain score (cm on a Visual Analogue Scale) at 6 different points during oocyte collection

    Measured: Actual point in time

  2. Length of oocyte collection procedure

    Measured: Time taken (minutes)

  3. Occurence of nausea or vomiting

    Measured: During oocyte collection procedure

  4. Administration of atropine or anti -emetic

    Measured: During oocyte collection procedure

  5. Time spent in recovery room

    Measured: Time from end of oocyte collection until discharge home

  6. No of oocytes collected

    Measured: During oocyte collection procedure

  7. Number of oocytes fertilised

    Measured: Assessed 18 hours after oocyte collection

  8. Pregnancy outcome

    Measured: 7 weeks gestation

  9. Number of embryos frozen

    Measured: Within 6 days of oocyte collection

  10. Pulse rate at beginning and end of egg collection

    Measured: Point in time

  11. Maximum pulse rate during oocyte collection

    Measured: Point in time during oocyte collection procedure

Questions about this trial

What is this clinical trial studying?

A study testing lignocaine and normal saline in people with Infertility, run by The Fertility Centre, New Zealand at 1 site in New Zealand.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Nov 2007. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in New Zealand. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Total dose of iv fentanyl used during oocyte collection (time frame: Length of oocyte collection (minutes)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2007.
