Abstract
OBJECTIVE
To examine the association between fetal death and risk of hemorrhage and disseminated intravascular coagulation (DIC) among women undergoing dilation and evacuation (D&E) procedures.
METHODS
We conducted a retrospective cohort study of all D&Es at one academic abortion clinic in San Francisco between 2009 and 2013. We abstracted data on fetal death status, demographic characteristics, and complications including hemorrhage and DIC. We examined the risk of hemorrhage and DIC among women with fetal death compared with those without. We conducted unadjusted and adjusted analyses for the outcomes of hemorrhage, DIC, and any complication.
RESULTS
Among 92 cases of D&E for fetal death and 4,428 cases of D&E for other reasons, hemorrhage occurred in 10% and 7%, respectively (P=.28), and DIC occurred in 2.0% and 0.2% of the fetal death and nonfetal death cohorts (P<.001). In adjusted analysis, fetal death was associated with 2.9 times higher odds of hemorrhage (95% CI 1.4-6.0). In an unadjusted analysis, fetal death was associated with 12.3 times higher odds of DIC (95% CI 2.6-58.6) and 3.0 times higher odds of any complication (95% CI 1.6-5.9).
CONCLUSION
Women undergoing D&E for fetal death are far more likely to experience DIC and hemorrhage than are women without fetal death, yet the absolute risk is low (2%). Although D&E providers should be prepared for DIC and hemorrhage, we do not recommend any specific preoperative preparation because the vast majority of D&E abortions for fetal death are uncomplicated.
