A study testing Cold Stimulus (Ice) in people with Epidural/Anesthesia, run by NYU Langone Health at 1 site in United States.
Trial summary
Pregnant women, with a Body Mass Index (BMI) greater than 30 kg/m2, who receive epidural analgesia/anesthesia for childbirth will have epidural catheter placement per our standard procedure, which includes using the gravity flow technique to confirm that the tip (aperture) of the epidural needle is indeed located… Read more about this study

About this study
Pregnant women, with a Body Mass Index (BMI) greater than 30 kg/m2, who receive epidural analgesia/anesthesia for childbirth will have epidural catheter placement per our standard procedure, which includes using the gravity flow technique to confirm that the tip (aperture) of the epidural needle is indeed located within the epidural space. The study procedure will be to use a cold stimulus (ice) to assess the subjects for hypesthesia the dermatomes of the lower abdomen between 10 and 30 minutes after the epidural catheter is inserted. Hypesthesia to cold will be taken a sign of successful lumbar epidural block.
Read the detailed description
The purpose of this study is to quantify the reliability of the gravity flow technique to accurately validate the position of the epidural needle tip when performing lumbar epidural analgesia/anesthesia for childbirth (vaginal and cesarean delivery) in women with a BMI greater than 30 kg/m2.

Cold Stimulus (Ice)Other
The study procedure will be to use a cold stimulus (ice) to assess the subjects for hypesthesia the dermatomes of the lower abdomen between 10 and 30 minutes after the epidural catheter is inserted.
| Study group | Role | What they receive |
|---|---|---|
| Epidural analgesia/anesthesia for childbirth | Experimental | Not described Receives: Other: Cold Stimulus (Ice) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Measure of bilateral decrease of sensation to cold with ice
Loss of sensation to ice; Following epidural procedure, subjects will be assessed to see if their epidural analgesia is working by determining if they have hyperthesia to ice on lower abdomen.
Measured: 30 Minutes Post Intervention

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?
Measure of bilateral decrease of sensation to cold with ice (time frame: 30 Minutes Post Intervention). 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.
