目的:探讨碳酸氢钠和钙剂对预防产后出血的作用。方法:选择总产程8 h或第二产程1 h以上的产妇100例,50例作为试验组予以5%碳酸氢钠125 ml及葡萄糖酸钙2 g,对比两组血钙浓度(Ca2+)及二氧化碳结合率(CO2CP),观察子宫收缩情况、第三产程及统计产后出血量。结果:试验组血Ca2+及CO2CP较高,子宫收缩较好,第三产程较短,产后出血量明显减少,结果有统计学意义。结论:产程中使用碳酸氢钠和钙剂对预防产后出血有作用。
Objective: To investigate the effect of sodium bicarbonate and calcium on postpartum hemorrhage. Methods: 100 maternal women were enrolled in this study. One hundred and fifty maternal women were recruited for the first 8 hours of labor or more than 1 hour of second delivery. Fifty patients (5% sodium bicarbonate and 2 g calcium gluconate) were given as experimental group. The levels of Ca2 + Binding rate (CO2CP), observation of uterine contractions, the third stage of labor and statistical postpartum hemorrhage. Results: The experimental group, blood Ca2 + and CO2CP higher, better uterine contraction, shorter third labor, postpartum hemorrhage was significantly reduced, the results were statistically significant. Conclusion: The use of sodium bicarbonate and calcium in the labor process has an effect on the prevention of postpartum hemorrhage.
