Abstract: Objective To evaluate effects and safety of sufentanil for labor analgesia as compared with fentanyl.Methods One hundred and twenty ASA Ⅰ full term primipara who were 25～28 years old and had a single fetus were expected to have a vaginal delivery and were randomly divided into 3 groups: group S(n=40),sufentanil 0.5 mg/L+0.1% ropivacaine in pump,group F(n=40),fentanyl 2 mg/L+0.1% ropivacaine in pump,group C(n=40),received no analgesia.The VAS score,first inject drug time,cervix dilation,uterine intermittent of uterus contraction,mode of delivery,postpartum hemorrhage,amount of oxytocin required and Apgar score of neonates were recorded.Results Compared to group C,group S and group F had higher rate of satisfactory analgesia(P<(0.01)).There was no difference in VAS score(P>0.05) between group S and group F.There was no significant difference in brith process time,intermittent of uterus contraction,mode of delivery,postpartum hemorrhage,amount of oxytocin required,rate of neonatal asphyxia and cesarean section,degree of motor block(P>0.05).There was the first stage of labor shortened tendency with group S.Conclusion Epidural anesthesia with sufentanil is effective and safety for labor analgesia,the active stage of labor can be shortened.
