Trial summary

Chorionic villous sampling is a frequent procedure used for antenatal genetic testing. This procedure is associated with anxiety and fear of pain that can be expected during the procedure, often prejudicing patients against this definitive antenatal testing. Read more about this study

About this study

Official title: A Randomized Trial to Determine if Local Anesthesia Decreases Pain Perception in Women Undergoing Chorionic Villus Sampling

Chorionic villous sampling is a frequent procedure used for antenatal genetic testing. This procedure is associated with anxiety and fear of pain that can be expected during the procedure, often prejudicing patients against this definitive antenatal testing. It is important to determine if different approaches to pain and anxiety reduction are effective. Currently there is no randomized study to evaluate the efficacy of analgesia for pain reduction during chorionic villous sampling. Multiple studies have been published suggesting that analgesia during the similar procedure of amniocentesis does not significantly reduce pain scores.

Read the detailed description

Chorionic villous sampling (CVS) is a frequent procedure used for antenatal genetic testing. This procedure is associated with anxiety and fear of pain that can be expected during the procedure, often prejudicing patients against this definitive antenatal testing. It is important to determine if different approaches to pain and anxiety reduction are effective. Previous studies have not shown that local anesthesia affects pain experience during amniocentesis (1-5). There are no randomized studies evaluating interventions for pain reduction during chorionic villous sampling which constitutes an important evidence gap.

The study will be offered to women at <13 weeks gestation, with a singleton fetus who are seen at Mount Sinai Medical Center for chorionic villous sampling. The eligible women will be randomized to one of two groups: use of analgesia using injectable lidocaine or ethyl chloride topical anesthetic spray. This study intends to show that local anesthesia during chorionic villous sampling will not decrease the perception of pain in patients undergoing this procedure.

This trial is trying to determine perception of pain based on use of injectable lidocaine or ethyl chloride anesthetic spray; it is noted that the form of anesthesia may be a factor in perception of pain. The investigators do not know if there is a difference in perception for topical or injectable. If the perceived pain is comparable in topical and injectable, this trial could conclude that both are viable options, and while both present minimal risk to patients, topical is less invasive.

What participants receive

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

  • Lidocaine injectionDrug

    Injectable anesthesia is 1-2mL of 2% lidocaine via a 22 gage needle, given at the anticipated site of CVS needle puncture immediately before procedure.

  • Gebauer Ethyl Chloride SprayDrug

    Gebauer Ethyl Chloride Spray is a topical anesthetic spray which is sprayed continuously for 3-7 seconds from a distance of 3-9 inches at the site where the chorionic villus sampling is expected to take place.

What is being measured

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

  1. Visual Analog Scale (VAS) Pain perception scores VAS ()

    Procedure pain perception score as measured by the visual analog scale. By means of analysis of the receiver operating characteristic curves on a 100mm VAS: no pain 0-2 mm, mild pain 2-17 mm, moderate pain 17-47 mm, severe pain 47-77 mm, very severe pain 77-96 mm, most severe pain imaginable 96-100 mm

    Measured: day 1

  2. Verbal Rating Scale (VRS)

    Procedure pain perception score as measured by the Verbal Rating Scale. 0=no pain, 1=mild pain, 2=moderate pain, 3=severe pain, 4=very severe pain, 5=most severe pain imaginable

    Measured: day 1

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Lidocaine injection and Gebauer Ethyl Chloride Spray in people with Chorionic Villi Sampling, run by Angela Bianco at 1 site in United States.

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 2 inclusion and 3 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 25 Oct 2017. 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 United States. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Visual Analog Scale (VAS) Pain perception scores VAS () (time frame: day 1). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03140293, which also lists 6 linked publications.

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 25 Oct 2017.
