Comparing auto-bolus intervals for labor analgesia

The Effect of Changing the Programmed Auto Bolus Interval Time On Analgesic Quality of Labor Analgesia With Dural Puncture Epidural Technique: Double-Blind Randomised Controlled Study

Not applicable Interventional Ataturk University · NCT06329713

This study is testing whether giving pain relief during labor every 30 minutes or every 60 minutes works better for women having their first baby.

What this trial studies

This study aims to evaluate how different programmed auto-bolus intervals of local anesthetics affect the quality of labor analgesia using the dural puncture epidural technique. It will be a prospective randomized, controlled, double-blind trial involving healthy nulliparous women aged 20 to 45 during active labor. Participants will be randomly assigned to receive either a 30-minute or a 60-minute interval for auto-bolus administration. The study will assess total anesthetic consumption and the overall effectiveness of pain relief during labor.

Who should consider this trial

Good fit: Ideal candidates are healthy nulliparous women aged 20 to 45 with singleton pregnancies who are in active labor and meet specific medical criteria.

Not a fit: Patients with pregnancy-related comorbidities, contraindications for neuraxial blocks, or those requiring cesarean sections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the quality of pain management during labor for women, leading to improved childbirth experiences.

How similar studies have performed: While similar studies have explored labor analgesia techniques, this specific approach to auto-bolus intervals is relatively novel.
