Using ephedrine to improve fetal heart monitoring during labor
Official title: Impact of Prophylactic Ephedrine on Fetal Heart Tracing and Uterine Tetanic Contraction After Combined Spinal Epidural on Laboring Parturients
Run by Icahn School of Medicine at Mount Sinai · NCT05873218 · Data updated 2026-11-12
This study tests if giving ephedrine to women in labor who are using spinal-epidural anesthesia can help improve fetal heart monitoring and reduce low blood pressure.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are women aged 18-55 who are requesting labor analgesia and have a category I fetal tracing prior to anesthesia placement.
✕Probably not a fit
Patients who refuse neuraxial anesthesia or have a history of hypertension or category II or III fetal tracings prior to anesthesia placement may not benefit from this study.

What this trial studies
This study investigates the effects of prophylactic ephedrine on fetal heart rate tracings and uterine contractions in women receiving combined spinal-epidural anesthesia for labor analgesia. The research aims to determine if administering ephedrine can reduce the incidence of category II fetal heart rate tracings and low blood pressure, which are known side effects of this anesthesia method. Participants will be randomly assigned to receive either ephedrine or a normal saline placebo. The study is significant as it explores an investigational use of ephedrine in this context, which has not been routinely practiced.
Why it matters
Potential benefit: If successful, this approach could enhance fetal monitoring and improve outcomes during labor for patients receiving neuraxial anesthesia.
How similar studies have gone: While the use of ephedrine in this context is investigational, similar studies have explored its effects on blood pressure and fetal heart rate, indicating potential for success.
