笑气吸入在分娩镇痛中的应用

INHALATION OF LAUGHING GAS IN ANAGESIC LABOR

①目的 了解分娩过程笑气吸入镇痛的效果和对母儿的影响。②方法 将 2 0 0例产妇随机分为观察组和对照组 ,对照组除不吸入笑气外 ,其他产科处理与观察组相同。观察并比较两组的产痛程度、产程时间、分娩方式、新生儿Apgar评分、产后 2h出血量和产后出血率等。 ③结果 观察组阵痛强度评分 >2分者所占比例明显低于对照组 (χ2 =86 .2 3,P <0 .0 1) ;活跃期和总产程时间短于对照组 ,差异有显著性 (t=2 .4 2、2 .2 5 ,P <0 .0 5 ) ;两组新生儿Apgar评分、产后 2h出血量、产后出血率比较 ,差异均无显著性 (t=0 .97、1.5 8,χ2 =0 .2 5 ,P >0 .0 5 )。④结论 笑气吸入性分娩镇痛产程时间短 ,对母儿均无不良影响 。

Objective To study the effect of inhalation of laughing gas on relief of labor pain and its related effects on mothers and fetuses. Methods Two hundred parturients were randomly divided into the observation group and the control group. The parturients in the control group were given the same treatments as those in the observation group except the inhalation of laughing gas. The degree of labor pain, delivery process, Apgar score, quantity of intrapartum and postpartum hemorrhage were compared between the two groups. Results The score of labor pain in the observation group was significantly lower than that in the control group (χ 2=86.23, P<0.01),The duration of active phase and total delivery process in the observation group was significantly shorter than that in the control group(t=2.42,2.25;P<0.05). Apgar score, quantity of intrapartum and postpartum hemorrhage were not significantly different between the two groups (t=0.97,1.58;χ 2=0.25;P>0.05). Conclusion Analgesic labor with inhalation of laughing gas produces a short delivery process and shows no side effects on both mothers and fetus.
