ClinConnect Summary
This clinical trial is investigating how a specific type of pain relief called combined spinal-epidural (CSE) affects blood flow in pregnant women during labor. CSE is commonly used for quick pain relief, but it can sometimes lead to changes in the baby's heart rate. Researchers want to understand if CSE reduces blood flow in the mother's uterine artery and the baby's umbilical artery, which might explain why some babies experience a slower heart rate after this type of pain relief.
To participate in this study, women must be at least 18 years old, be in active labor with a single baby due for delivery, and be requesting pain relief. They should not have any major health issues or fetal problems before receiving the CSE. Participants will be monitored using a special ultrasound that checks blood flow before and after the CSE is given. This research aims to help doctors understand how CSE affects both the mother and the baby during labor, providing better care for mothers and their newborns.
