Uteroplacental Perfusion
Blood flow to the uterus and placenta that is critical for fetal oxygenation and can be affected by maternal anesthetic management.
Full Definition
Uteroplacental perfusion refers to the maternal blood flow that supplies the uterus and placenta, which is essential for adequate fetal oxygenation and nutrient delivery. This perfusion is directly related to maternal cardiac output and blood pressure, making it a critical consideration in obstetric anesthesia. Factors that can reduce uteroplacental perfusion include maternal hypotension (from neuraxial anesthesia), aortocaval compression, excessive uterine contractions, and certain medications. Anesthesiologists must carefully balance effective pain relief or surgical anesthesia while maintaining adequate maternal hemodynamics to preserve fetal well-being. Monitoring includes maternal blood pressure, heart rate, and fetal heart rate patterns that may indicate compromised uteroplacental circulation.
