Objective:
The objective of this study is to evaluate maternal outcomes before and after implementation of an institutional delayed cord clamping (DCC) protocol.
Study Design:
We performed a secondary analysis of a retrospective cohort study of deliveries occurring at <34 weeks at a tertiary care center in 2013-2014. About 139 women who underwent early cord clamping were compared with 130 women delivered after DCC protocol implementation. Maternal estimated blood loss (EBL) was the primary outcome of interest. Operative times, post-Cesarean decrease in hemoglobin (Hgb), and rates of post-partum hemorrhage and transfusion were also examined in bivariate and multivariable analyses.
Results:
About 75% of post-guideline deliveries had actual DCC. In regression analyses, only Cesarean delivery and multifetal gestation increased EBL. No trends were identified in EBL over time. In post-hoc analysis, the study had over 80% power to detect a difference in post-partum hemorrhage rates of 20%.
Conclusion:
An institutional DCC protocol for deliveries <34 weeks was not associated with an identifiable increase in adverse maternal outcomes.
