When the fetus has already engaged and there is nuchal cord occurrence, it is generally unlikely for the wrapping to unwind again. This is because once the fetus has engaged, the fetal position is fixed, and the fetus will no longer change its position, making the nuchal cord a more fixed condition. When dealing with nuchal cord, it is important to observe the number of loops and whether the tightness of the loops could impact the fetus. Therefore, it is necessary to regularly attend prenatal appointments at the hospital to monitor its developmental condition. If the nuchal cord loops just once around the neck, it usually does not affect the baby.
