血清钙浓度对产妇产程进展及产后出血的影响

The influence of serum calciumion concentration on the progress of labor and postpartum hemorrhage

目的探讨孕产妇血清钙浓度对产程及产后出血的影响。方法选择自然分娩,无合并症、并发症的产妇1 348例进行产前血清钙浓度检测,按所测血清钙浓度结果(血清钙正常参考值2.1～2.6 mmol/L)分为低钙组(502例)、正常血钙组(721例)和高钙组(125例),比较各组的第二及第三产程时间、产后出血量、子宫收缩乏力及产后出血发生率等方面的差异。结果低钙组第二及第三产程时间延长、产后出血量多,子宫收缩乏力和产后出血发生率高,与正常血钙组、高钙组比较,差异有统计学意义(P均<0.01)。结论孕产妇在产前和产中适量补充钙剂可以预防产程延长和减少产后出血量。

Objective To study the relationship between serum ealeiumion concentration, the progress of labor and postpartum hemorrhage. Me, otis In this study, 1348 normal puerperas who was natural childbirth were selected, and according to the normal ealeiumion concentration （2. 1 ± 2. 6 retool/L） in our hospital, they were divided into low calcium group （ n = 502）, normal calcium group （ n = 721 ） and high calcium group （ n = 125 ）. The differences in the time of second and third stage of labor, the incidence of uterine atony, postpartum hemorrhage ete between the three groups were compared. Results Compared with the last two groups, the low calcium group had a longer stage of labor process, more amount of bleeding in postpartum hemorrhage, a higher incidence of uterine atony and postpartum hemorrhage. （all P 〈 0. 01 ）. Conclusion In order to prevent and reduce postpartum hemorrhage, puerpera＇ s calcium supplementation is necessary.
