Objective: To observe the clinical effect of analgesia labor with inhaling N 2O. Methods: 253 pregnant women selected randomly in this hospital were divided into analgesia labor group (123 cases) and non-analgesia labor group (130 cases). Delivery course, postpartum hemorrhage, delivery way, amniotic fluid character and newborn's asphyxia of two groups were analyzed statistically.Results: The first delivery course and total course of analgesia labor group were shorter than that of control group ( P <0.01). The second and third course, postpartum hemorrhage, amniotic fluid character have not significant difference between two groups ( P >0.05). Newborn's asphyxia in control group was more than that in analgesia labor group, but there were not significant difference between two groups ( P >0.05). Conclusion: Analgesia labor with inhaling N 2O is a safe and effective method worth popularization and application.
