Objective To investigate the efficacy of transcutaneous electrical acupoint stimulation combined with continuous epidural anesthesia in labor analgesia for primiparas and its effect on labor outcomes.Methods Using the random number table method,160 primiparas were divided into Group E,Group T,Group E+T and Group C,40 cases in each group.In labor analgesia,Group E were treated with continuous epidural anesthesia;Group T were treated with transcutaneous electrical acupoint stimulation;Group E+T were treated with transcutaneous electrical acupoint stimulation combined with continuous epidural anesthesia;Group C didn't carry out labor analgesia.Delivery method,duration of labor,postpartum hemorrhage rate,pain scores based on visual analog scale(VAS)before analgesia and when the uterine opening was 2,4 and 6 cm and when the uterus was fully open,Apgar scores of newborns after 1,5 and 10 minutes of birth,the serum β-endopeptide levels before analgesia and when the uterine opening was 4cm and when the uterus was fully open,were compared in the 4 groups;dosage of analgesic drugs were compared in Group E+T and Group E.Results The rate of spontaneous delivery in Group E+T was significantly higher than that in Groups E,T and C;the first and second stages of labor were significantly shorter than those in Groups E,T and C,and the difference was statistically significant(P＜0.05).The difference in the incidence of postpartum hemorrhage among the 4 groups was not statistically significant(P＞0.05).The differences in VAS scores and the serum β-endopeptide levels before analgesia were not statistically significant among the 4 groups(P＞0.05).The VAS scores at 2,4 and 6cm of opening and at full opening of the uterus in Group E+T were significantly lower than those in Groups E,T and C;the VAS scores in Groups E and T were significantly lower than those in Group C;and the VAS scores in Group E were significantly lower than those in Group T;the differences were statistically significant(P＜0.05).The serum β-endopeptide levels at 4cm of opening and at full opening of the uterus in Group E+T were significantly higher than those in Groups E,T and C;the serum β-endopeptide levels in Group T were significantly higher than those in Groups E and C;the differences were statistically significant(P＜0.05).The Apgar scores of newborns after 1,5 and 10 mins of birth were compared among the 4 groups,and showed no statistically significant difference(P＞0.05);the dosage of analgesic drugs in Group E+T was significantly less than that in Group E,and the difference was statistically significant(P＜0.05).Conclusions Transcutaneous electrical acupoint stimulation combined with continuous epidural anesthesia can achieve relatively better efficacy in labor analgesia for primiparas,contributing to the improvement of labor outcomes.
