Umbilical cord around the neck is one of the common abnormalities in obstetric ultrasound, about 20-30% of fetuses have umbilical cord around the neck, is due to fetal activities in the uterine cavity before 32 weeks of pregnancy due to the relatively large space due to the umbilical cord due to entanglement, at the same time may be coexisting with the umbilical cord around the body, the umbilical cord around the limb situation. Some pregnant women see ultrasound fetal umbilical cord around the neck, the heart is very worried, some pregnant women will also joke: this child is too naughty, in the womb jump rope, accidentally become hanged. Jokes to jokes, but the umbilical cord around the neck must be taken seriously, mid-pregnancy, late fetal death in the uterus in the cause of the umbilical cord factors account for a large proportion of, especially around the neck at the same time combined with the winding of the limbs of the situation is more risky, or wrapped around the 2 circles or more risk is also greater; but there is no need to be anxious about the whole day to worry about the situation of the fetus death in the uterus, usually through the counting of the fetal movement to perceive the safety and security of the fetus in the uterus. If the umbilical cord is suddenly wound too tightly, resulting in fetal death in utero within a short period of time, the pregnant woman may not have any abnormal feeling at this time, even if you live in the hospital medical personnel can not be predicted, that is to say, wait for a long time you feel that the fetus has not moved or medical personnel to listen to the fetal heart found that can not be found to go to ultrasound to find that the fetus has been dead in the uterus, this is often very regrettable, the pregnant woman is also a painful thing; if the cord is wrapped around the neck leading to fetal death in the uterus, there are more risks; however, there is no need to be anxious all day long. If the umbilical cord around the neck leads to fetal hypoxia in the uterus, i.e., fetal distress in the uterus, and gradually the fetal movement decreases significantly, then you need to go to the hospital in time to consult the doctor, and perform fetal heart rate monitoring to reflect the fetal hypoxia in the uterus, such as fetal heart rate monitoring is non-responsive, and the sound stimulation is also non-responsive, you need to recheck and still non-responsive, you need to be hospitalized for further treatment, and timely cesarean section is needed to terminate the pregnancy if necessary, and of course, we should also consider the week of gestation and the size, viability, and complications of the fetus. Of course, it is also necessary to consider the gestational period and the size of the fetus, whether it can survive and complications. If the fetal movement is the same as before or there is no significant decrease, it means that the fetus is relatively safe in the mother’s body, and the umbilical cord around the neck does not need to be dealt with, so it can be seen that counting the fetal movement is very important.
