Abstract: Labor pain is a major cause for increased cesarean section rate and adverse pregnancy outcomes，but it can be controlled by interventions，among which labor analgesia is the most effective.Besides，it can also maintain maternal and infant safety and promote natural childbirth.In various labor analgesic methods，non-pharmacological analgesia produces less adverse reactions，but the analgesic effect remains to be confirmed.Drug-induced analgesia can relieve the labor pain，but with certain adverse reactions.So there are studies recommend the combination use of both drug- and non-drug-induced analgesia.Among different forms of drug-induced analgesia，epidural analgesia has a definite analgesic effect and a more flexible analgesic time，but requiring higher level of technique and costing more，with some controversies about the impact on maternal and neonatal outcomes.At present，the prevalence of domestic labor analgesia is far lower than that in foreign countries，wherefore it is necessary to strengthen the publicity，promotion and development of labor analgesia in China.
