摘　　要：目的:研究孕期微量元素状况对妇女产后出血的影响。方法:选取2012年4月至2014年3月在我院阴道分娩的产妇250例,根据产后阴道出血量分为A、B、C三组,A组为100例,产后出血量V≤300m L;B组为100例,产后出血量300m L<V≤500m L;C组为50例,产后出血量V>500m L。在分娩前,对A、B、C三组产妇均进行血清钙、铁、锌、镁、铜等微量元素浓度的检测。最后,进行相关数据的处理分析。结果:相对A组产妇,B、C两组产妇的血清钙、铁、锌等微量元素浓度显著降低;相对B组,C组产妇的血清钙、铁、锌等微量元素浓度显著降低,P均<0.05表明差异具有统计学意义。A、B、C三组产妇的血清镁、铜等微量元素浓度相比差异不明显,P>0.05表明差异不具有统计学意义。A、B、C三组产妇产后出血量与孕期血清钙、铁、锌等微量元素浓度的相关系数r均>0.6、相关性检验P<0.05,表明产妇产后出血量与血清钙、铁、锌的浓度有密切的相关性;A、B、C三组产妇产后出血量与孕期血清镁、铜等微量元素浓度的相关系数r均<0.1、相关性检验P>0.05,表明产妇产后出血量与血清镁、铜的浓度无相关性。结论:妇女孕期血清微量元素钙、铁、锌的浓度与产妇产后阴道出血量有密切的相关性;血清微量元素钙、铁、锌浓度的降低是致使产妇产后阴道出血量升高的一个因素。Objectives： To study the effect of trace elements status during pregnancy on postpartum hemorrhage. Methods： 250 vaginal delivery patients in our hospital from April 2012 to March 2014 were selected and divided into A, B, C, three groups according to the postpartum vaginal bleeding, 100 cases in the group A, V 300mL, 100 cases in the group B, Abstract L4 300mL 〈 V ≤500mL, 50 cases in group C, V 〉 500mL. Before delivery, concentrations of calcium, iron, zinc, magnesium, copper and other trace elements in serum of group A, B and C were detected and analyzed. Results： Comparing with group A, the concentrations of calcium, iron, zinc and other trace elements in serum of group B and C significantly decreased; comparing with group B, the concentrations of calcium, iron, zinc, and other trace elements in serum of group C significantly decreased, with statistically sig- nificant difference （ P 〈 0. 05 ）. Concentrations of magnesium, copper and other trace elements in serum of group A, B and C had no significant difference, P 〉 0. 05. Correlation coefficient between the amount of postpartum hemor- rhage and concentrations of calcium, iron, zinc, and other trace elements in sermn of group A, B and C was r 〉 0. 6, correlation test P 〈 0. 05, which showed a close correlation between concentration of serum calcium, iron, zinc and the amount of postpartum hemorrhage; Correlation coefficient between the amount of postpartum hemorrhage and concentrations of magnesium, copper and other trace elements in serum of group A, B and C was r 〈 0. 1, correla- tion test P 〉 0.05, which showed no close correlation between concentration of serum magnesium, copper and the amount of postpartum hemorrhage. Conclusion： There is a close correlation between concentration of serum calcium,iron, zinc and the amount of postpartum hemorrhage ; the reduct：ion of concentration of calcium, iron, zinc is one factor causing postpartum vaginal bleeding increase.
