ABSTRACT

Objective To investigate the effects of epidural labor analgesia in latent phase on the puerperae and their newborns. Methods A total of 240 spontaneous parturient primiparae who received labor analgesia were selected from Decem-ber 2015 to January 2017 in Kaifeng Obstetrics and Gynecology Hospital. The primiparae were divided into observation group and control group,with 120 cases in each group. The puerperae in the observation group were performed with patient-controlled epidural analgesia(PCEA)in the latent phase,and the puerperae in the control group were performed with PCEA in the active phase. The puerperae received PCEA with 10 - 15 mL mixed liquor of ropivacaine mesylate and sufentanil citrate by self-con-trolled analgesia pump after epidural puncture. The time of the first stage of labor(T 1 ),the time of the second stage of labor (T2),visual analogue scale(VAS)score,uterine-incision delivery and the satisfaction degree of analgesia were observed. The blood pressure and heart rate of puerperae during the period of analgesia,and the neonatal Apgar score,the incidence of neo-natal asphyxia were compared between the two groups. Results The T1 and T2 of parturient in the observation group were sig-nificantly shorter than those in the control group (P < 0. 05),and the VAS score was significantly lower than that in the control group (P < 0. 05). There was no significant difference in blood pressure and heart rate between the two groups during the anal-gesia period (P > 0. 05). In the control group,the rate of cesarean section and the satisfaction of analgesia were 10. 83％ and 70. 83％ respectively;the rate of cesarean section and the satisfaction of analgesia were 3. 33％ and 95. 83％ respectively in the observation group. The rate of cesarean section in the observation group was significantly lower than that in the control group (χ2 = 5. 128,P < 0. 05),and the satisfactory rate of analgesia was significantly higher than that in the control group (χ2 = 27. 000,P < 0. 05). There was no significant difference in Apgar score of neonate between the two groups (P > 0. 05). Neonatal asphyxia rates in control group and observation group was 3. 0％ and 2. 5％ respectively;there was no significant difference in asphyxia rate between the two groups (χ2 = 0. 147,P > 0. 05). Conclusion The effect of epidural labor analgesia in latent phase is satisfactory. It can shorten the birth process and reduce the rate of cesarean section,and the maternal and in-fant risk is not increased.
