EST for Labor Pain
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a method to reduce labor pain by verifying the placement of an epidural catheter, which delivers pain relief during childbirth. The researchers aim to use an Electrical Epidural Stimulation Test (EST) to ensure the catheter is correctly positioned before and after administering pain medication. This trial is for pregnant women ready to give birth who want an epidural to manage labor pain. Participants should not have allergies to specific pain medications or certain medical conditions, such as neurological disorders.
As an unphased trial, this study allows participants to contribute to research that could enhance epidural procedures for future patients.
Will I have to stop taking my current medications?
The trial requires that you do not use sedatives or opioids, so you would need to stop taking those medications if you are currently using them.
What prior data suggests that this technique is safe for labor pain management?
Research has shown that electrical stimulation methods, such as the Electrical Epidural Stimulation Test (EST), are generally safe. Studies examining the use of electrical stimulation to locate the epidural space during cesarean sections found it to be safe. Additionally, research on similar methods for managing labor pain, like Transcutaneous Electrical Nerve Stimulation (TENS), indicates they are well-tolerated. Although no medical procedure is entirely risk-free, existing studies suggest that EST is a safe option for managing labor pain.12345
Why are researchers excited about this trial?
The Electrical Epidural Stimulation Test (EST) is unique because it offers a novel approach to managing labor pain by using electrical stimulation instead of traditional methods like epidural anesthesia or systemic pain medications. Researchers are excited about this technique because it allows them to measure sensory and motor responses both before and after administering local anesthetics, potentially leading to more personalized pain management strategies. Unlike standard treatments, which mainly focus on blocking pain signals, EST could help optimize anesthetic use and improve overall comfort during labor by providing real-time feedback on the body's response to pain relief interventions.
What evidence suggests that the Electrical Epidural Stimulation Test (EST) is effective for labor pain?
Research has shown that Transcutaneous Electrical Nerve Stimulation (TENS), similar to the Electrical Epidural Stimulation Test (EST) studied in this trial, can reduce labor pain. TENS has proven effective in lowering pain levels for women during labor. In one study, 90% of women using TENS reported satisfaction with the pain relief it provided. Although direct evidence for using EST to manage labor pain is limited, its similarity to TENS suggests potential benefits. Additionally, electrical stimulation has been used to accurately locate epidural spaces, which may support its effectiveness in managing labor pain.46789
Are You a Good Fit for This Trial?
This trial is for women over 18 who are in full-term pregnancy and want epidural pain relief during labor or C-section. They should be generally healthy (ASA I or II). It's not for those with allergies to certain anesthetics, sedative/opioid use, abnormal spine anatomy, neurological issues affecting the lower back, or implanted electronic devices.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Electrical Epidural Stimulation Test (EST)
Trial Overview
The study tests a method called Electrical Epidural Stimulation Test (EST) to confirm correct placement of epidural catheters used for continuous pain relief during childbirth. This technique was developed by the principal investigator about two decades ago.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Laboring women are given EST test initially before local anesthetic is administered and 1 hour post-anesthetic in order to measure sensory and motor responses.
