产力宝加速第二产程的研究

Clinical Study on Chanlibao in Accelerating Second Stage of Labor

目的 :观察中药产力宝在第二产程中的临床效果。方法 :将观察期间本院经阴道分娩的初产妇随机分为 3组 ,分别为产力宝组(80例 )、催产素组 (5 2例 )及自然分娩组 (2 9例 ,不用任何药物) ,观察比较各组第二产程时间及母儿预后 ,并通过电子监护仪进行内监护测定子宫内压及胎儿心率变化。结果 :产力宝组产妇第二产程时间及产后出血量均明显小于自然分娩组 ,其平均子宫内压明显高于后者 ,但与催产素组间无显著性差异。对新生儿预后无不良影响。结论 :产力宝具有显著加强产力 ,缩短第二产程作用 ,副作用小 ,给药方便 ,不失为临床一安全有效的改善母儿预后的药物 ,尤其适用于不宜使用催产素及不宜大量输液者。

Objective: To find out a new way to strengthen the uterine contraction and shorten the second stage of labor, for improving the prognosis of mother and newborn. Methods: primiparae observed were divided into three groups randomly and Chanlibao (CLB, a preparation of Chinese herbal medicine) or oxytocine (OTC) was given to the CLB group (80 cases) and the OTC group (52 cases) respectively, to the third group, as a control group (29 cases) of natural labor, without any drug was given. Time of second stage of labor (TSL) and prognosis of mother and newborn of different groups were observed and compared. And intrauterine pressure (IP) and fetal heart rate were monitored by means of electronic monitor. Results: TSL and postpartum hemorrhage in the CLB group were less than those in the control group. The average IP in former was higher than that in latter, but with no difference as compared with the OTC group. No side effect of CLB was found. Conclusion: CLB could obviously strengthen uterine contraction and shorten the TSL, it is cheap, convenient and with no side effect, so it is a new safe, effective method for improving prognosis of primiparae and newborn, especially for those nonindicated in using oxytocine or infusion of fluid profusely.
