Abstract

Introduction: We examined the perinatal outcomes in Japanese singleton pregnancies associated with meconium-stained amniotic fluid (MSAF) in relation to gestational age at delivery. Methods: We reviewed the obstetric records of all Japanese singleton deliveries after 22 weeks’ gestation managed at Japanese Red Cross Katsushika Maternity Hospital between 2002 and 2008 (n = 11,249). Results: The incidence of MSAF in the whole singleton pregnancies was 13%. The incidence of MSAF at preterm, term and post-term were 9.1%, 13% and 48%, respectively. The incidence of intrauterine fetal death, low Apgar score and low umbilical artery pH at delivery in cases with MSAF were significantly higher than those without MSAF in various gestational ages at delivery. Conclusion: Obstetric management should be affected by meconium in the amniotic fluid.
