BACKGROUND: There are few reports in the literature of the risks associated with second @entity5852 in @entity1 with @entity5030 ( @entity5030 ). We hypothesise that @entity5030 increases the risk of complications. AIMS: We sought to determine if @entity5030 is associated with a higher risk of @entity190 and blood transfusion at the time of dilation and evacuation (D_E). MATERIALS AND METHODS: The records of 612 consecutive @entity1 undergoing abortion at 15-24  weeks of gestation were reviewed. @entity1 characteristics, need for blood transfusion, estimated @entity190 (EBL) during the abortion and other complications were compared between @entity1 with and without ultrasound-documented @entity5030 . RESULTS: Eighty-seven of 612 (14.2%, 95% CI 11.5-17.2%) @entity1 had ultrasound-documented @entity5030 . The rate of blood transfusion was 3.4 and 1.3% in the group with @entity5030 and without @entity5030 , respectively (adjusted relative risk (RR  =  2.8, 95% CI 0.7-11.3). An estimated @entity190 of 500  cc or greater during the D_E procedure was observed in 12.6% of @entity1 in the @entity5030 group compared with 4.2% of @entity1 in the group without @entity5030 (adjusted RR 3.1, 95% CI 1.4-6.8, P  =  0.004). CONCLUSIONS: Second- @entity5852 in @entity1 with @entity5030 is associated with a higher risk of @entity190 of 500  cc or greater. Our study represents a larger sample size of @entity1 with @entity5030 undergoing second- @entity5852 than previously reported in the literature. @entity1 with @entity5030 may have a higher estimated @entity190 and may require access to blood transfusion.
