Methods We adopted four methods that single cpidural block anesthesia or narcotics analgesies were injected into subarachnoid space and epidural space or single narcotics was injected into subarachnoid space (group C fentanly 25μg;group D fentanly 20μg) to study analgesia birth for 130 nullipara women. The analgesia efficacy, side effect, birth time md mode,postpartum haemorrhage and the condition of the fetus and the newborn were compared.
