Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are females aged 18 and older who are full-term pregnant and requesting epidural analgesia during labor.

Probably not a fit

Patients with contraindications to regional anesthesia or those with certain medical conditions, such as neurological disorders or implanted electronic devices, may not benefit from this study.

What this trial studies

This study investigates the effectiveness of the Electrical Epidural Stimulation Test (EST) to confirm the placement of epidural catheters in obstetric patients seeking pain relief during labor. The combined spinal-epidural technique is utilized to provide rapid analgesia, but the study aims to enhance this method by ensuring proper catheter placement through EST. The research focuses on women who are full-term and requesting epidural analgesia, assessing the safety and efficacy of this approach in a clinical setting.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of epidural catheter placement, leading to better pain management for laboring women.

How similar studies have gone: While the EST technique has been previously described, this specific application in obstetric patients is novel and has not been extensively tested in similar studies.
