Abstract：Objective To analyze the effect of self-control background dose epidural anesthesia, and to explore a more conducive way for maternal and newborn infants. Methods 100 cases of natural childbirth in our hospital were selected and randomly divided into the observation group with background dose of self-control epidural anesthesia and the test group without background dose of epidural an-esthesia. There were 50 people in each group, with 6 mL/h as the background dose. Those parturient women were evaluated by VAS score after anesthesia, the adverse reaction and the delivery mode of the two groups were compared before and after the maternal produc-tion. Furthermore, the new born infants were given neonatal Apgar test, and the maternal dose of the two groups of was compared. Re-sults There were no adverse reactions in the two groups, and there were no obvious differences in terms of the incidence of adverse reac-tions. In the test group, there were 36 cases of mechanical midwifery and 14 cases of cesarean section. In the observation group, the number was 34 and 16 respectively. The mode of delivery was not significantly different. In the test group, the blood gas indexes, such as the breathing rate, heart rate and blood oxygen saturation, were higher than those of the observation group, and there were no significant differences. After VAS score, all the parturient women achieved good anesthetic effect without pain tolerance. The newborn infants were evaluated by Apgar score 5 minutes after delivery, in which there were no infants under 4 points. The neonatal average score of the two groups were (7.52±2.12) and (7.61±2.56) respectively. The difference was not obvious (P>0.05). Conclusion The Epidural an-esthesia, with or without background dose, can both achieve good anesthesia effect to parturient women. Epidural anesthesia without background dose can lead to relatively large fluctuations to maternal blood gas index, while anesthesia with background dose may lead to high allergic reactions. To sum up, the pattern of anesthesia should be chosen according to maternal anesthetic tolerance.
