| Objective:To study the effect of DDI for emergency cesarean section on Apgar score and umbilical artery pH after labour analgesia.Methods:125 cases were collected which failed in vaginal delivery and converted to cesarean section after labour analgesia in Changchun Obstetrics and Gynecology Hospital from December 2018 to June 2019.Based on 30 minutes of DDI,all cases were divided into two groups.A total of 68 cases were included in group A(DDI<30 min),and 57 cases were included in group B(DDI<30 min).Comparisons were made between groups in regard to maternal characteristics,indication for cesarean section,DDI,Apgar score(lmin and 5min)and umbilical artery pH.Results:In this study,there were 53 cases covered to cesarean section due to fetal distress which is the first indication of cesarean section among all cases.The second indication was prolongation or stagnation of labor causing a total of 49 parturients delivered by cesarean section.The median DDI in two groups was 16.75 minutes and 32 minutes.Apgar scores at 1 minutes and 5 minutes had no differences between the two groups(P>0.05).Six(8.82%)neonates umbilical artery pH was less than 7.2 in group A,and 12(21.05%)in group B.Group B had more cases with umbilical artery pH<7.2,but there was no significant difference between the two groups(P>0.05).Univariate logistic regression analysis of risk factors of pH<7.2 showed that,the OR(95%CI)of Apgar at 1 min and 5 min was lower than 1,indicating that higher Apgar score causes less pH<7.2(P<0.05);the OR(95%CI)of fetal distress and amniotic fluid contamination was>1,which indicated that both were risk factors of pH<7.2(P<0.05).Conclusion:Our study showed that there were no significant effects on neonatal outcomes when DDI was more than 30 minutes after labour analgesia. |
