Description

Summary

This study is being done to determine the most effective dose of medicine to use to initially provide effective pain relief within the first 30 minutes of receiving an epidural for pain labor during labor. The study team will also study any side effects related to the epidural medication and patients' satisfaction with the quality of pain relief after receiving the epidural.

Official Title

Determination of the 90% Effective Volume (ED90) of Epidural 0.1% Ropivacaine and Fentanyl for Labor Analgesia Initiation in Patients Receiving a Dural-Puncture Epidural Technique

Details

We aim to perform a prospective observational study in a single cohort of 50 patients receiving a dural-puncture epidural technique for labor analgesia. We will use a biased-coin up-down allocation methodology to quantify the volume of a combined epidural 0.1% ropivacaine and 2 mcg/ml fentanyl regimen that achieves effective analgesia in 90% of patients experiencing active labor who receive a dural-puncture epidural technique for labor analgesia.

    I study how we can close the gap between what we know and what we do in managing severe maternal complications such as postpartum hemorrhage. My research focuses on developing strategies to improve clinical preparedness, response, and decision-making in the prevention and management of postpartum hemorrhage.
