Maternal Obesity & Risks in Uterine Rupture Setting

Obstet Gynecol; ePub 2017 Mar 6; Yao, et al

Maternal obesity moderately increases the risk of low Apgar score, neonatal intensive care unit admission, prolonged ventilation, and seizure in the setting of uterine rupture; however, risk of maternal complications and the risk of neonatal death are similar to risks in patients of normal body mass index (BMI). This according to retrospective cohort analysis of singleton nonanomalous neonates born after uterine rupture between 34 and 42 weeks of gestation. 3,942 cases of uterine rupture were identified among 15,860,954 births between 2011 and 2014; 2,914 met inclusion criteria for analysis. Researchers found:

  • An increased risk of low 5-minute Apgar score, neonatal intensive care unit admission, and seizure in obese compared with normal-weight pregnancies was observed.
  • The rate of prolonged assisted ventilation was 8.5% vs 6.3% (OR, 1.47).
  • Rate of neonatal deaths was similar, as were rates of various maternal complications, between groups.
