The AMNIO-BRAIN Trial: A Randomized Trial of Amnioinfusion for Chorioamnionitis Targeting Neonatal Brain Injury Biomarkers

Summary

The AMNIO-BRAIN Trial is a research study looking at whether a simple treatment during labor can help protect a baby's brain. Some newborns develop a condition called hypoxic-ischemic encephalopathy (HIE), which happens when the brain does not get enough oxygen or blood flow. This can lead to serious health problems, including developmental delays and lifelong disabilities. While there is a cooling treatment after birth that can help, it starts only after delivery and may come too late to prevent the earliest stages of injury. Research suggests that some brain injury may actually begin during labor, especially when there is an infection in the uterus called chorioamnionitis. This infection can cause inflammation and fever in the mother, which may increase stress on the baby and affect the baby's brain. This study is testing whether a commonly used labor procedure called amnioinfusion can help. Amnioinfusion involves placing fluid similar to your biologic amniotic fluid into the uterus during labor. It is already used safely in many deliveries for other reasons. In prior research, this treatment slightly lowered the temperature inside the uterus and improved signs that the baby was no longer under stress. In this study, 80 pregnant subjects with chorioamnionitis will be randomly assigned to receive amnioinfusion during labor or receive standard care without amnioinfusion. All patients will continue to receive normal treatment for infection. After delivery, researchers will collect a small sample of blood from the umbilical cord. This blood will be tested for markers that can show whether the baby may have experienced stress or injury to the brain.
