At 30 weeks of gestation and one week of fetal encirclement, it is sufficient to count fetal movements and perform regular obstetric examinations. The causes of cord bypass are related to the long umbilical cord, small fetus, excessive amniotic fluid and frequent fetal movements, etc. It cannot be changed artificially, so no special treatment is needed. Cord bypass is a common condition during pregnancy, most of them are 1 week or 2 weeks. During labor, when the fetal head is moving downward, the umbilical cord becomes relatively shorter and affects the progress of labor. In addition, if the cord is stretched due to the number of weeks of encirclement or too tight, or if the cord is compressed due to contractions, it may lead to fetal hypoxia. Therefore, pregnant women should be highly alert to frequent or reduced fetal movements and consult the hospital promptly to rule out intrauterine distress. The umbilical cord is not an absolute indication for cesarean delivery. Most children with a 1-week cord winding undergo a normal delivery and almost no accidents will occur, while children with a 2-week cord winding may show signs of hypoxia, but the chances are not high.
