妊娠合并子宫肌瘤分娩出血量的相关因素分析

Analysis on related factors of amount of blood loss during delivery in pregnant women combined with hysteromyoma

目的:探讨影响妊娠合并子宫肌瘤孕妇分娩出血量的相关因素。方法:2007～2011年在产前检查时发现子宫肌瘤且至少有1个直径≥5 cm肌瘤的孕妇192例,分析产妇的年龄、产次、分娩方式、新生儿体重及肌瘤的数量、单发肌瘤的最大径线、多发肌瘤最大径线之和、肌瘤的位置与分娩出血量的关系。结果:孕妇的年龄及肌瘤的数量与出血量呈正相关,而分娩方式、新生儿体重及肌瘤的大小和位置与出血量无显著相关性。结论:高龄和多发性子宫肌瘤是妊娠合并子宫肌瘤孕妇分娩出血量多的重要因素,必须提前做好产前准备,备足充足的血源,以避免严重产后出血导致产妇死亡。

Objective： To explore the related influencing factors of amount of blood loss during delivery in pregnant women combined with hysteromyoma. Methods： A total of 192 pregnant women were found with hysteromyoma and at least the diameter of one myoma≥ 5 cm during prenatal examination from 2007 to 2011 ; the relationship between maternal age, parity, delivery modes, neonatal weight, the number of myoma, the longest diameter of single myoma, the sum of longest diameters of multiple myoma, the location of myoma and the amount of blood loss during delivery was analyzed. Results： There was a positive correlation between maternal age, the number of myoma and the amount of blood loss ; delivery modes, neonatal weight, the size and location of myoma were not correlated with the amount of blood loss during delivery. Conclusion： Advanced age and multiple hysteromyoma were important factors inducing excessive hemorrhage during delivery in pregnant women combined with hysteromyoma, prenatal preparation should be conducted and sufficient blood resource should be prepared to avoid maternal death induced by serious postpartum hemorrhage.
