“GT-4A导乐分娩镇痛工作站”的临床效果观察

GT-4A workstation for pain relief during labor

目的探讨不同分娩镇痛方法的临床效果和对产妇及新生儿的影响。方法将130例产妇随机分为三组:A组(50例)为使用“GT-4A导乐分娩镇痛工作站”进行镇痛;B组(40例)为吸入含50%笑气与50%氧气的混合气体镇痛;C组(40例)为空白对照。观察镇痛效果、产程时间、分娩方式、产后出血等。结果A组、B组均有镇痛作用,与C组比较差异均有统计学意义(P<0.01),A组镇痛效果好于B组,差异有统计学意义(P<0.01)。A组活跃期为[(206.7±15.4)min]、第二产程[(28.8±2.4)min],均明显短于B组[(254.7±13.9)min和(49.8±3.8)min]、C组[(259.4±14.8)和(50.4±4.4)min](P值均<0.05),A组总产程(654.2±35.1)min短于C组(759.5±25.7)min(P<0.05)。结论“GT-4A导乐分娩镇痛工作站”具有良好的镇痛效果,对母儿均无不良影响,操作简单方便,产妇乐于接受,不失为一种理想的分娩镇痛方法,适于在基层单位推广使用。

Objective To investigate the effect of different analgesia during labor and their side effect to the neonates. Methods Totally 130 puerperas were randomly divided into three groups.. group A included 50 puerperas with analgesia by GT-4A workstation; group B included of 40 puerperas with mixed gas analgesia consisted of 50G of nitric oxide and 50% of oxygen; and group C（40 gravidas） as control group. The analgesic effect, duration of labor, mode of delivery and the amount of postpartum hemorrhage were observed. Results The analgesic effect in group A was significantly better than group B （P〈0.01）. The duration of the active phase and the second stage of labor in group A [（206.7±15.4） min, （38. 8±3. 4） mini was significantly shorter than those of group B [（254.7±13.9） min,（49. 8±3. 8） mini and C [（259.4±14.8） min,（50.8±4.4） mini （P〈0.05）. Conclusions GT-4A workstation for analgesia during labor works ettectively without severe side effect on mothers and babies.
