양수과소증과 자궁내 성장지연이 있는 저위험 산모군에서 자궁내 성장지연이 주산기 예후로서 갖는 의의

Abstract

Objective: To assess whether intrauterine growth restriction in company with oligohydramnios in which umbilical blood flow or uterine arterial flow is normal, is more correlated with adverse perinatal outcomes than isolated oligohydramnios.

Methods: We collected data from the records of one-hundred and twenty-seven patients terminated at term, namely between 37+1 and 41+0, who were diagnosed oligohydramnios around 37 gestational weeks at the Department of Obstetrics and Gynecology, the Yonsei Medical Center from January 1995 to July 2006. Oligohydramnios was defined as an AFI <5 cm. Perinatal outcomes in pregnancies with isolated oligohydramnios were compared with those with oligohydrmanios in company with intrauterine growth restriction which did not show abnormal umbilical blood flow or abnormal uterine arterial flow. The perinatal outcome variables were cesarean delivery for fetal distress, 1-minute Apgar score of less than 3, 5-minute Apgar score of less than 7, presence and the degree of meconium staining, admission to neonatal intensive care unit and the percentage of the case which were in neonatal intensive care unit more than eight days.

Results: Of 127 patients, 22 cases (17.3%) were in company with intrauterine growth restriction and oligohydramnios which did not show abnormal umbilical blood flow, 105 cases (82.7%) with isolated oligohydramnios. There were statistically no significant difference between the maternal characteristics and perinatal morbidity and mortality (P>0.05).

Conclusions: Intrauterine growth restriction in company with oligohydramnios which does not show abnormal umbilical blood flow, in otherwise low-risk term pregnancy, does not mean worse perinatal outcomes than isolated oligohydramnios (P>0.05).
