This thesis is to research the effect in delivery and neonatal outcomes from the existence of nuchal cord coiling and its frequencies. Materials and METHODS: The research had been made during the period between Jan, 1997 and Jul, 1998 in College of medicine, Hallym University. It examined the process of delivery and 1min/5min apgar score, fetal weight, and gas measurement of umbilical vessel with the objects of 1st group of 100 full-term women without nuchal cord coiling, 2nd group 125 full-term women with only 1 time of nuchal cord coiling, and 3rd group of 25 full-term women with more than 2 times of nuchal cord coiling. Results; Nuchal cord coiling showed the frequencies of 17.81% [14.85% in 2nd group, 2.96% in 3rd group]. There were almost no discrepancies between 1st group and 2nd group in the frequencies of an abnormal fetal heart rate, a meconium staining, and an emergency cesarean section. However, Discrepancies were found between 1st/2nd groups and 2nd/3rd groups. The frequencies of 1min apgar score, macrosomia in neonatal outcome were some discrepancies between 1st/2nd groups and 3rd group. In 5min apgar score, fetal weight, no discrepancies were found. In gas measurement in umbilical vessels, pH showed some discrepancies only between 1st/2nd groups and 3rd group and no discrepancies between groups were found in gas measurement for pO2, pCO2, and HCO3. CONCLUSION: Because more than 2 times of nuchal cord coiling can affect the delivery and outcome, proper treatment from the prenatal diagnosis can help the being of pregnant women and her fetus.
