目的 探讨笑气吸入用于无痛分娩对母儿的影响。方法 对 10 0例产妇在分娩过程中给予吸入 5 0 %笑气与 5 0 %氧气混和气体以实施无痛分娩 (研究组 ) ,另选择 10 0例产妇在分娩过程中仅吸入氧气作对照 (对照组 )。观察两组产妇的产程时间、分娩方式、分娩时失血量、其新生儿出生时Apgar评分 ,及产妇桡动脉血及新生儿脐血血气分析结果。结果 研究组无痛分娩有效 97例 ;总产程时间平均 3 2 6 2 7min ,全部为自然分娩 ,失血量平均 194 4 4ml,新生儿Apgar评分均 >7分。对照组无痛分娩有效为 0例 ,总产程时间平均 3 64 82min ,自然分娩 98例 ,钳产助娩 2例 ,失血量平均199 78ml,新生儿Apgar评分均 >7分。两组产妇无痛分娩效果比较 ,差异有极显著性 (P <0 0 0 1)。两组产妇产程时间、分娩方式、分娩时失血量 ,及新生儿Apgar评分比较 ,差异无显著性 (P >0 0 5 )。产程中两组产妇的血压、心率均无明显波动。两组产妇桡动脉血及新生儿脐血血气分析结果比较 ,差异无显著性 (P >0 0 5 )。结论 笑气吸入用于产妇分娩镇痛 ,对母、儿及产程无不良影响 ,且有利于产妇在分娩中保持较好的心理状态和体力 ,对胎儿有利。是安全、有效。
Objective To investigate the effect of the inhalation of nitrous oxide premixed with oxygen (50%∶50%) for analgesia labor on maternal and fetus. Methods A total of 100 cases of pregnant women were provided with nitrous oxide premixed with oxygen (50%∶50%) (control group); Another 100 cases were provided only with oxygen (comparison group). Recording duration of the Labor, way of delivery, bleeding volume, Apgars score, blood gas analysis to maternal radius artery and fetal umbilical blood among all patients. Results The effect for analgesia labor of the premixed gas was much better than that of control group, but there were no significant differences in time of labor, bleeding volume, Apgars score between the two groups. Conclusions The inhalation of nitrous oxide premixed with oxygen (50%∶50%) for analgesia labor benefits pregnant women because of keeping them being a good mental and physical condition.
