A common question doctors are asked during prenatal care or in the delivery room is, “My baby has a wrapped umbilical cord, is it an increased risk? What can I do to help my baby “unwind”? Cord wrapping is one of the most common questions asked during prenatal consultations. We know that the umbilical cord is a very important fetal appendage during fetal life. It is a cord-like organ that connects the fetus to the placenta and plays a very important role in the transport of material, and it is the length of the cord that allows the baby to swim freely in the amniotic fluid. The vast majority of umbilical cord entanglement to the fetus is temporary Normally, the length of the umbilical cord at full term is approximately between 30 and 1750 px. If it is shorter than 750 px, the cord is called too short, and if it is more than 1750 px, the cord is called too long. In fact, cord winding is only one kind of cord wrapping around the fetal body. Because the umbilical cord has a certain length and the movement of the fetal baby, it inevitably causes the cord to wrap around the fetus, including the cord wrapping around the neck, the cord wrapping around the body, and the cord wrapping around the limbs. At the same time, because of the above reasons, most of the umbilical cord entanglement to the fetus is temporary and will release itself; moreover, it does not pose any obvious harm to the fetus, so pregnant mothers should not worry about it. Cord entanglement is not uncommon clinically and is not dangerous during the fetal period. Nowadays, due to the variety and accuracy of prenatal examination methods, we can detect cord entanglement during the ultrasound of the baby, especially the detection rate of cord entanglement is significantly higher than that of cord entanglement and cord entanglement of limbs. Cord entanglement is not uncommon clinically, accounting for about 20% of cases. The risk is not significant in the fetal period. Do not be overly anxious if you have a baby wrapped around your neck. The best thing to do when the baby is wrapped around the neck is for the pregnant mother to monitor the fetal movement. Because there is no effective way to help the baby “get unstuck”, the best way is to perform your daily mommy duties and pay attention to the baby’s movements from late pregnancy onwards. We know that with the development of the nervous system and the skeletal and muscular systems, the daily movement of the fetal baby (also known as “fetal movement”) will have a certain regularity, and with the sleep habits of the fetal baby, every pregnant mother can appreciate the movement of the fetal baby more clearly. Although we do not have to count the fetal movements every moment, we can count the fetal movements at a fixed time every day to get a general idea of the condition of the baby. If the number of fetal movements increases or decreases by more than 50%, or if the baby is agitated, you should be alert and go to the hospital for examination. This is because if the fetus is lacking oxygen in the womb, the fetal movement is the first objective indicator that can be reflected, and only the pregnant mother can feel it herself. In fact, there are some umbilical cord factors that cause fetal accidents, but this is a very rare phenomenon and cannot be predicted by all current medical methods. From my personal point of view, the ultrasonographer’s report of fetal cord entanglement is, from a perinatal point of view, a reminder for the health care provider to monitor the fetus more closely and, on the other hand (and most importantly in my opinion), a reminder for the obstetrician to monitor the baby more closely during labor. This is because as labor progresses, the fetus moves forward and if the cord is wrapped around too many times, the umbilical cord’s freedom to descend is limited, which can cause slow descent (stagnation) or abnormal fetal heartbeat. Medical staff in the delivery room will pay more attention to mothers who have a cord wrapped around their neck and monitor them more closely to detect signs of fetal hypoxia as early as possible. Mothers who have experienced childbirth will remember that during labor, the medical staff will pay close attention to the fetal heart rate, the color of the amniotic fluid and the rate of descent of the fetal foregut, especially at the end of labor, the monitoring time will be shortened to 10 minutes and the fetal heart will be monitored continuously if necessary. Unless the umbilical cord is too long, a normal length of cord with too many wraps will increase the chance of abnormalities during labor. Therefore, the indications for elective cesarean delivery are usually relaxed if the cord is wrapped around the neck more than three times. If the cord is wrapped around the neck 1 to 2 times, the majority of fetal babies will be born safely under the protection of the medical staff.
