About this study

Official title: Time for Neuraxial Block Placement With Use of Ultrasound in Patients With High BMI

This is a prospective experimental pilot study of full-term non-emergent obese parturients whose labor is being managed with epidural anesthesia to determine if neuraxial block placement with pre-procedure handheld ultrasound affects time to placement or number of needle passes. Approximately 25 patients, presenting for delivery at the University of Kentucky HealthCare Obstetrics Department, will be randomized to either the ultrasound or palpation group, between study approval and 31 July 2022.

Read the detailed description

Placement of neuraxial blocks is commonly achieved by palpating surface landmarks. This somewhat "blind" technique to identify the spinal space becomes more difficult and less reliable in obese patients. Ultrasound devices have become common and successful with blocks and venous access, both involving mostly soft tissues. Application of conventional ultrasound for neuraxial blocks has been limited by its bulkiness, limited imaging for bony structures and a long learning curve. A newly developed pocket-size ultrasound addresses these limitations by providing real-time pattern recognition for spinal bony structures and 3D overlay for recognition of midline spinous process and intervertebral space using an automated artificial intelligent algorithm. The hypothesis is that ultrasound guidance will reduce time to epidural placement and reduce number of passes in obese patients.

What participants receive

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

  • Neuraxial block placementProcedure or surgery

    The time and ease of administering neuraxial blocks in high BMI patients,for the management of labor and delivery pain, will be assessed.

What is being measured

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

  1. Time to placement of neuraxial block in parturients with BMI=35-59.9

    Time period from initially touching the patient's skin to removal of Tuohy needle after catheter placement.

    Measured: Time from start of epidural procedure to placement of epidural needle, not to exceed more than1 hour

  2. Number of passes to placement of neuraxial block in parturients with BMI=35-59.9

    Number of times the epidural needle is removed from skin and re-entered

    Measured: Time from start of epidural procedure to placement of epidural needle, not to exceed more than1 hour

Questions about this trial

What is this clinical trial studying?

A study testing Neuraxial block placement in people with Obesity Complicating Childbirth, run by University of Kentucky 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 4 inclusion and 7 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 Jan 2023. 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.

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?

Time to placement of neuraxial block in parturients with BMI=35-59.9 (time frame: Time from start of epidural procedure to placement of epidural needle, not to exceed more than1 hour). 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?
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 Jan 2023.
