目的:探讨孕期微量元素状况对产妇产后出血的影响。方法:选择2015年1月~2016年6月在北京平谷妇幼保健院行孕期保健并阴道分娩的产妇320例的临床资料进行分析。按照产后出血量进行分析,<250 ml为小出血量组,≥250ml且<500 ml为中出血量组,≥500 ml为大出血量组。比较各组血清微量元素水平,分析孕期微量元素水平与产后出血量的相关性。结果:小出血量组血清Fe、Ca及Zn水平显著高于中出血量组及大出血量组,而中出血两组显著高于大出血量组,差异有统计学意义(P<0.05)。血清中Fe、Ca、Zn微量元素水平与产后出血量呈显著负相关的关系(P<0.05)。结论:产妇孕期血清微量元素水平影响产后出血量,孕期注意监测孕妇微量元素,及时补充,可预防产后大量出血。
Objective: To investigate the effect of trace elements during pregnancy on postpartum hemorrhage in maternal. Methods: From January 2015 to June 2016, we analyzed the clinical data of 320 pregnant women with vaginal delivery during pregnancy during pregnancy in Pinggu Maternal and Child Health Hospital of Beijing. According to the amount of postpartum hemorrhage analysis, <250 ml for the small bleeding group, ≥ 250ml and <500 ml for the group of bleeding, ≥ 500 ml for the bleeding group. The serum levels of trace elements in each group were compared, and the correlation between trace element levels in pregnancy and postpartum hemorrhage was analyzed. Results: The levels of Fe, Ca and Zn in the small bleeding group were significantly higher than those in the middle and large bleeding group, while those in the middle bleeding group were significantly higher than those in the large bleeding group (P <0.05). The serum levels of Fe, Ca, Zn trace elements and postpartum hemorrhage was significantly negatively correlated (P <0.05). Conclusion: The levels of serum trace elements in pregnant women during pregnancy affect the amount of postpartum hemorrhage. During pregnancy, trace elements in pregnant women should be monitored and supplemented in time to prevent massive postpartum hemorrhage.
