Effects of Labor Analgesia at Different Timing on Labor,Delivery Mode and Maternal and Infant Outcomes of Primipara under the New Labor Standard
Objective:To explore the effect of labor analgesia at different timing on labor,delivery mode and maternal and infant outcomes of primipara under the new labor standard.Method:A total of 129 primiparas who had natural delivery in Tengzhou Central People's Hospital from January 2022 to February 2023 were selected and divided into group Ⅰ(n=43,dilatation of cervix≤2 cm),group Ⅱ(n=43,2 cm<dilatation of cervix<3 cm)and group Ⅲ(n=43,dilatation of cervix≥3 cm)according to different delivery analgesia timing.All primiparas received continuous epidural block for labor analgesia.The labor,analgesic effect,delivery mode and maternal and infant outcomes of the three groups were compared.Result:There were no significant differences in natural delivery rate and transit cesarean section rate among the three groups(P>0.05).Compared with group Ⅰ and group Ⅱ,the first and total stage of labor in group Ⅲ were shorter,and the second stage of labor was longer(P<0.05).Compared with group Ⅰ,the first and total stage of labor in group Ⅱ were shorter,and the second stage of labor was longer(P<0.05).The total effective rate of analgesia in group Ⅲ(95.35%)was higher than that in group Ⅰ(73.81%)and group Ⅱ(78.57%),the differences were statistically significant(P<0.05).The incidence of adverse maternal and infant outcomes in group Ⅲ(11.63%)was lower than that in group Ⅰ(34.88%)and group Ⅱ(30.23%),the differences were statistically significant(P<0.05).Conclusion:Although labor analgesia when dilatation of cervix≥3 cm will prolong the second stage of labor,it can shorten the first and total stage of labor,improve the analgesia effect,and reduce the incidence of adverse maternal and infant outcomes,the timing of labor analgesia can be reasonably selected according to the actual situation of primipara in clinic.
