Abstract

OBJECTIVE

To estimate the rate of requiring more than one 300-mcg Rh D immune globulin dose for fetomaternal hemorrhage (FMH) at the time of second-trimester dilation and evacuation (D + E).

STUDY DESIGN

We performed a retrospective cohort analysis of patients at greater than 20 weeks' gestation who underwent D + E, had Rh D-negative blood type, and received FMH quantification testing.

RESULTS

Of 25 eligible patients, 24 had negative quantification of FMH; one had positive quantification that did not meet the clinical threshold for additional dosing.

CONCLUSIONS

The absolute risk of requiring additional Rh D immune globulin after D+E for pregnancies greater than 20 weeks' gestation was 0%.

摘要

目的

评估在妊娠中期扩张和排空术（D+E）时，因胎儿母亲出血（FMH）需要不止一剂 300 微克 Rh D 免疫球蛋白的几率。

研究设计

我们对大于 20 周妊娠、行 D+E、Rh D 阴性血且接受 FMH 定量检测的患者进行了回顾性队列分析。

结果

25 名符合条件的患者中，24 名 FMH 定量检测为阴性；1 名 FMH 定量检测为阳性，但未达到追加剂量的临床阈值。

结论

对于大于 20 周妊娠的 D+E 后需要额外 Rh D 免疫球蛋白的绝对风险为 0%。
