Because of what happens the cord is entangled with the umbilical cord of the fetus?
As a rule, such a phenomenon as cord embryology occurs before the 32nd week of pregnancy, and is already observed on 2 scheduled ultrasound (20-22 weeks). This happens for several reasons. The most frequent of them is an increasing, oxygen deficiency, which leads to an increase in the motor activity of the fetus.
The second most common cause leading to a similar situation is the too long umbilical cord of the fetus. This is observed when its length exceeds 70 cm. As a result of the fetal movement in the maternal womb, the umbilical cord loops are formed, which fall on the neck of the baby.
How do doctors work if there is an umbilical cord around the neck at week 32?
As a rule, before this date, doctors do not pay attention to this phenomenon, explaining this by the fact that until the time of delivery, the fetus will change its position more than a dozen times. As a result, the loop can be unraveled or formed again.
In the case of the detection of a single cord by the umbilical cord at week 32, the woman is under special control. So, already closer to 37 weeks, repeat ultrasound. If there is still a loop on the neck, this fact is taken into account at the beginning of the birth process, and directly at delivery.
What is dangerous cord hanging?
The most, perhaps, dangerous consequence of this phenomenon is suffocation, and as a result - hypoxia of the fetus. If an umbilical cord is detected on ultrasound earlier than 32 weeks, an additional examination, in the form of a doppler and a cardiotocography, may be prescribed. It is these types of studies that can exclude hypoxia.
Speaking about whether it is dangerous to cord with the umbilical cord at week 32, it is necessary to say that everything depends on which loop and how many. Thus, a double entrainment at the 32nd week of pregnancy is an indication for enhanced monitoring of the condition of both the fetus and the pregnant one. In such cases, the chances of developing suffocation are great, in which the stimulation of labor or even a cesarean section may be prescribed, if such is already present in an anamnesis in the future mother.
Thus, everything depends on the above nuances. But in most cases, such a phenomenon, as a cord with the umbilical cord, does not require medical intervention, tk. The loop is often untangled by the time of delivery.
