目的:探讨钙剂在分娩镇痛过程中的应用价值。方法:在实施分娩镇痛的孕妇出现宫缩力弱时,将其随机分为两组。实验组立即给予钙剂,如产程仍无进展,加用缩宫素;对照组不予特殊处理,如产程进展缓慢,使用缩宫素。结果:实验组92例孕妇中,有20例使用钙剂后宫缩好转,不需要使用缩宫素;对照组92例孕妇中,只有9例宫缩自行好转;实验组孕妇的活跃期、第二产程时间和产后24h出血量分别为(161±62)min、(81±39)min、(321±54)ml,对照组的分别为(183±76)min、(94±43)min、(344±61)ml,二组差异均有统计学意义。实验组和对照组相比,胎粪Ⅱ～Ⅲ度污染无统计学差异,均无新生儿窒息发生。结论:在分娩镇痛中早使用钙剂,可降低缩宫素的使用率。钙剂与缩宫素联合应用,可缩短活跃期及第二产程的时间,减少产后出血量。
Objective: To explore the value of calcium in labor analgesia. Methods: In the implementation of labor analgesia pregnant women appear contractions weak, they were randomly divided into two groups. Experimental group immediately given calcium, such as labor process is still no progress, with oxytocin; control group without special treatment, such as slow progress of labor, the use of oxytocin. Results: Among the 92 pregnant women in experimental group, 20 cases of uterine contractions improved after using calcium, and no need of oxytocin was used. Only 9 of 92 pregnant women in control group improved uterine contractions; The time of second labor and the amount of hemorrhage after hysterectomy were (161 ± 62) min and (81 ± 39) min and (321 ± 54) ml respectively, while the control group were (183 ± 76) min and (94 ± 43) (344 ± 61) ml, the difference between the two groups was statistically significant. The experimental group and the control group, meconium Ⅱ ~ Ⅲ degree of pollution was no significant difference, no neonatal asphyxia. Conclusion: Early use of calcium in labor analgesia can reduce the use of oxytocin. Calcium and oxytocin combined application, can shorten the active phase and the second stage of labor time, reduce postpartum hemorrhage.
