摘　　要：目的探讨分娩期吸入氧化亚氮镇痛方法对产妇及新生儿的影响。方法 200例无合并症及并发症的初产妇,在宫口开大3cm时,吸入氧化亚氮进行分娩镇痛,设为观察组;200例同期相同条件的产妇设为对照组,两组进行产程、分娩方式、产后出血量、剖宫产率、新生儿Apgar评分和产妇疼痛程度比较。结果镇痛组胎儿窘迫、新生儿Apgar评分、产后出血量和对照组比较差异无显著性。产程进展显著快于对照组,剖宫产率显著低于对照组,镇痛组疼痛明显减低,两组差异有显著性(P<0.01)。结论吸入氧化亚氮进行分娩镇痛,具有疼痛轻、对母婴影响小、给药起效快、产妇清醒、不影响宫缩、缩短产程、降低剖宫产率等优点,值得在临床推广使用。【Objective】To detect the effect on puerpera and neonatal by nitrous oxide inhalation during delivery. 【Methods】200 cases of primipara with no complication were as observer group, they used nitrous oxide when cervical was enlarged by 3 cm during delivery, 200 cases pregnant with the same condition were as control group, two groups were compared with the labor stage, delivery mode, postpartum hemorrhage rate, caesarean-section rate, neonatal Apgar score and maternal pain.【Results】There were no difference in fetal distress, neonatal Apgar score, postpartum hemorrhage rate between two groups, but the labor stage in study group was significant faster than that of control group. The caesarean-section rate was marked lower in study group than that of control group. Analgesic pain group was significantly lower, two groups were significantly different （P 0.01）. 【Conclusion】The analgetic effect by nitrous oxide during delivery was light in pain, less effect to maternal and neonatal, easy to give drug, the effect more quickly. The prenatalls kept clear head, affected nothing to uterine contraction, shorten labor stage, and reducing the caesarean section rate, etc. The analgetic method is worth application in clinics.
