Effects Of Application Of Labor Analgesia At Different Stages Of The First Stage Of Labour On Maternal And Infant Outcomes

Objective:To explore the effects of the use of epidural block delivery analgesia at different stages of the first stage of labour on maternal and infant outcomes.Methods:A total of 144 full-term primiparas admitted to the Department of Obstetrics and Gynecology of Bengbu Third People’s Hospital from April 2021 to April 2022 were selected.The patients who did not perform labor analgesia were selected as the control group,and the patients who performed labor analgesia were selected as the observation group.According to the timing of the implementation of labor analgesia,they were divided into observation group 1(uterine orifice dilation <3cm),observation group 2(3cm≤uterine orifice dilation ≤4cm)and observation group 3(uterine orifice dilation >4cm).The timing of labour,the rate of transit caesarean section,the rate of perineal cleavage,the rate of midwifery delivery,and the Apgar score of newborns were compared among the groups.Results:The first stage of labor time in the observation group 1 was significantly longer than that in other groups(P<0.01),and the difference in the time of second and third stages of labor was not statistically significant in each group(P>0.05).The natural birth rate in the observation group was higher than that in the control group(P<0.05).The rate of transit caesarean section in the observation group was lower than that in the control group(P<0.01).There was no statistically significant difference in the comparison of the rate of later resection and the rate of midwifery delivery between the observation groups(P>0.05).The natural birth rate of the observation groups 3 was significantly higher than that in the observation group 1(P<0.01),and the rate of transit caesarean section in the observation group 3 was significantly lower than that in the observation group1(P<0.01).The 1-minute Apgar score and 5-minute Apgar score of neonates in the observation group 1,2 and 3 and the control group were compared,and the results were not statistically significant(P>0.05).Conclusions:The application of labour analgesia techniques can significantly reduce the rate of caesarean section during delivery and reduce the adverse effects of caesarean section on mother and infant.It was also no significant effect on neonatal outcomes.It can be promoted and applied in clinical work.Therefore,labor analgesia can be preferentially selected when the uterine orifice is dilated to 3-4 cm.
