Abstract
Objective: We examined the impact of the abruption severity and the onset-to-delivery time on the maternal and neonatal outcomes of cases of clinically diagnosed placental abruption (PA).
Material and methods: We investigated 84 patients who were diagnosed with PA at our hospital from January 2009 to September 2017. We classified the patients with PA into three groups based on the extent of the abruption: (1) mild abruption, <20%; (2) moderate abruption, 20–49%; (3) severe abruption, ≥50%, which was defined by the attending obstetricians at the time of delivery. The neonatal outcome was measured by the umbilical artery pH and the maternal outcome was measured by the obstetric disseminated intravascular coagulation score (DIC score).
Results: The rate of hypertensive disorders of pregnancy in the moderate abruption group was significantly lower than that in other groups (p = .010). The umbilical artery pH was below 7.00 in 29 cases. The umbilical artery pH of the severe abruption group (6.92) was the lowest and was significantly lower in comparison to other groups (mild group [7.24], p < .001; moderate group [7.11], p < .05). There was a significant correlation between the onset-to-delivery time and the umbilical artery pH in the moderate group (R = −0.43). The maternal DIC scores in the three groups did not differ to a statistically significant extent.
Conclusions: The severity of placental separation is significantly correlated with poor neonatal outcomes and there was a significant negative correlation between the onset-to-delivery time and the umbilical artery pH in moderate abruption.
