Loss of diastolic flow in the umbilical artery in the seventh month of pregnancy requires active intrauterine resuscitation and, if necessary, termination of pregnancy.
During pregnancy, obstetrical examination should be performed on time as prescribed by the doctor, and those with high risk factors such as gestational hypertension and thrombophilia should be managed during pregnancy, and ultrasound umbilical blood flow monitoring should be performed as prescribed by the doctor to assess the intrauterine status of the fetus. When the ultrasound in the seventh month of pregnancy suggests that the diastolic flow of the umbilical artery has disappeared, there is a risk of intrauterine hypoxia, and intrauterine resuscitation therapy such as oxygenation and rehydration needs to be given in a timely manner.
If the fetal heart rate monitoring after active treatment suggests a reactive pattern, the labor can be continued under close monitoring of fetal movement and fetal heart rate changes as prescribed by the doctor, and the umbilical blood flow should be rechecked at intervals of 1~2 days, but when the monitoring is unresponsive or accompanied by deceleration, it is necessary to terminate the pregnancy in a timely manner, and timely preparation for neonatal resuscitation is required.
