RÉSUMÉ
Objective: To investigate the effect of epidural block analgesia on childbirth, mother and child. Methods: A retro-spective study was used. Totally 200 primipara were divided into two groups according to the analgesia method. The 100 cases in the observation group was undergone lumbar epidural puncture and cathetering at the 2-3 section when the cervix was with 2-3cm opening, 0. 075% ropivacaine hydrochloride and sufentanil 10ml was infused firstly, and then 0. 075% ropivacaine and sufentanil was infused continuously through a self-control analgesia pump at the speed of 6-8ml·h-1 till the cervix was nearly all opened. The other 100 cases in the control group were without anesthesia when the cervix was with 2-3cm opening. The analgesia effect, labor time, delivery mode, postpartum hemorrhage amount, fetal distress and postpartum hemorrhage of the two groups were compared. Results:The analgesic ef-fective rate of the observation group was 97. 0%, which was significantly higher than that of the control group (10. 0%, P0. 05). Conclusion:Ropivacaine at low concentration combined with sufentanil used in epidural block analgesia has promising analgesic effect, which can shorten labor time to promote the smooth delivery.
