Umbilical cord around neck

Umbilical cord around the neck is a common situation during fetal delivery, and it is generally believed that this is related to excessive umbilical cord and excessive fetal movement. It is expected that the length of blood vessels will be longer than that of the umbilical cord. Usually, the blood vessels are curled in a spiral shape, and the umbilical cord itself is surrounded by gelatin and has a certain degree of elasticity. Therefore, the number of weeks around the neck has no direct relationship with the fetal survival. Only after labor, with the tightening of the uterine contraction, the descending fetal head will tighten the wound umbilical cord, which will cause the umbilical cord to be too short, and it will not be able to deliver smoothly. At this time, the more winding cycles are more dangerous. B-ultrasound can be used to see if the fetus has an umbilical cord around the neck before birth, and sometimes a more pronounced umbilical murmur can be heard in the abdomen. Therefore, at this time, it is more necessary to listen to the fetal heartbeat and pay attention to fetal movements in order to take timely measures.
