Determination of the 90% Effective Volume of Epidural 0.1% Ropivacaine and Fentanyl for Labor Pain Relief Using a Dural-Puncture Epidural Technique

What this Trial Is About

This research aims to find the best dose of a medicine mixture to provide quick pain relief within 30 minutes during labor using an epidural. It focuses on women in active labor who are receiving a dural-puncture epidural technique for pain relief. The study also examines any side effects from the epidural medication and how satisfied patients are with their pain relief experience. The study involves giving a combined epidural medication made of 0.1% ropivacaine and 2 mcg/ml fentanyl to participants. Researchers will use a special method to determine the volume of this mixture that works effectively for 90% of patients during labor. The study will observe one group of 50 patients who meet the criteria and are receiving this epidural technique. Participants will be monitored closely during labor after receiving the epidural medication. Researchers will measure pain levels 30 minutes after the epidural is given using a numerical pain score. They will also watch for any medication side effects and collect feedback on satisfaction with pain relief. The study is planned to start in October 2025 and continue until July 2026, involving women aged 18 or older with single pregnancies in active labor.
