目的:观察卡前列甲酯栓(卡孕栓)预防产后出血的效果。方法:200例产妇随机分为直肠放置卡孕栓+缩宫素组67例(I组),舌下含服卡孕栓+缩宫素组68例(Ⅱ组)和缩宫素组65例(Ⅲ组),比较三组产妇第三产程时间、产后2 h出血量及血压的变化。结果:I组与Ⅱ组产妇产后2 h出血的量及第三产程时间均明显少于Ⅲ组产妇,而血压变化差异无统计学意义。结论:卡孕栓配伍缩宫素促进子宫收缩的作用强于单纯应用缩宫素,能较好的预防产后出血。 OBJECTIVE: To observe the effect of methyl palmitate suppository (carboplatin suppository) in preventing postpartum hemorrhage. Methods: 200 maternal women were randomly divided into rectal placement of caesarean + oxytocin group of 67 cases (group I), sublingual card carboplatin + oxytocin group of 68 cases (group Ⅱ) and oxytocin group of 65 cases (Group Ⅲ). The duration of the third stage of labor, blood loss and blood pressure at 2 h postpartum were compared between the three groups. Results: The amount of bleeding and the third stage of labor in group I and group II were significantly less than those in group III at 2 hours postpartum, while the difference in blood pressure was not statistically significant. Conclusion: The effect of carbamazepine and oxytocin on uterine contractions is stronger than that of oxytocin alone, which can prevent postpartum hemorrhage better.
