In cases of nuchal cord, it is not advisable to attempt correcting abnormal fetal positions, because if the fetal position changes abnormally after an attempted correction while the umbilical cord is wrapped around the neck, it may worsen the degree of the nuchal cord, potentially leading to fetal hypoxia or even asphyxiation. However, if the umbilical cord is relatively long, it might not affect the changes in fetal position, and sometimes the fetus can automatically free itself from the nuchal cord through its own movements. It is important to regularly visit the hospital for prenatal check-ups to detect any other potential abnormalities.
