Abstract

Objective: We aimed to investigate the effect of failed vacuum delivery leading to an emergency cesarean delivery on the long-term pediatric hematologic morbidity of the offspring. Study Design: In this population-based cohort study, the risk of long-term hematologic morbidity (up to the age of 18 y) was evaluated in children born following successful vacuum vaginal delivery, as compared with that of children born following a failed procedure leading to an emergent cesarean delivery. Multiple pregnancies and fetuses with congenital malformations were excluded. A Kaplan-Meier survival curve was constructed to compare cumulative pediatric hematologic morbidity, and a Cox proportional hazards model was used to control for confounders. Results: A total of 7978 neonates met the inclusion criteria. Vacuum delivery was successful in 7733 cases (96.9%), whereas it failed in 245 cases (3.1%). Total hematologic morbidity of the offspring up to 18 years of age was comparable between the groups (1.6% vs. 0.8%, P=0.8). The Kaplan-Meier survival curve showed no difference in the cumulative incidence of total hematologic morbidity (log rank, P=0.22). In the Cox regression model, failed vacuum delivery was not independently associated with long-term hematologic morbidity, as compared with a successful procedure, while adjusting for multiple confounders (adjusted hazards ratio [HR], 1.8; 95% confidence interval, 0.7-5.0; P=0.25). Conclusions: Failed vacuum delivery does not seem to be associated with an increased risk for pediatric hematologic morbidity of the offspring up to 18 years of age.
