This study is looking for women aged 18 to 50 who are in labor and want an epidural for pain relief. You would need to be 37-42 weeks pregnant with a single baby, have no major health problems, and be less than 5 cm dilated with a pain score of 5 or higher. The study is testing different doses of bupivacaine hydrochloride, a medication used in epidurals, after you receive a standard lidocaine "test dose." The goal is to find the dose of bupivacaine that effectively relieves pain for 90% of patients. The study is currently recruiting 120 participants.

Study design

This interventional study plans to enroll 120 women. It uses a special method called a biased coin up-down allocation to determine bupivacaine doses.

What's involved

You would receive doses of bupivacaine as part of your epidural. Your pain level will be measured 30 minutes after the epidural is started.

Compensation
