ABSTRACT
ObjectiveTo evaluate the effect of labor analgesia and the outcome of maternals and neonatals by applying the vitamin B6- folic acid mixture to combined with spinal-epidural analgesia(CSEA) in nulliparous women at latency.MethodsAll the 112 full-term nulliparous parturients were selected and divided into the treated group and controlled group.Nulliparous women in two groups received CSEA,with which the additional vitamin - folic acid mixture was used only in treatment group.The contrast between the analgesic effect in groups,and alalgesic effect-acting period,fentanyl Apgar score and newborn usage were compared between groups also.ResultsThe analgesic effect-acting period and fentanyl dosage in the treated group were significantly decreased.There was significant difference between the 2 ( P ＜ 0.05 ).ConclusionsIt could be effective applying vitamin B6- folic acid mixture at latency in nulliparous women based on CSEA,which could shorten the lumbar hemp effect-acting period and reduce fentanyl narcotic drugs dosage.
