Objective To analyse the effect of full-term labour analgesia on the labour process and outcome of single full-term primigravid women under the new labour standard.Methods The clinical data of 360 singleton full-term primigravid women admitted to the Department of Obstetrics of Anqing Municipal Hospital from August 2021 to August 2023 were retrospectively analysed,and divided into an observation group(full-labour labour analgesia,n=180)and a control group(first-labour labour analgesia,n=180)according to the different methods of labour analgesia used.The two groups were compared in terms of the final mode of delivery,the degree of pain in different stages of labour and the outcome of mother and baby.Results Comparison of the rates of natural vaginal delivery,forceps-assisted delivery,intermediate cesarean section,artificial rupture of membranes,perineal laceration and postpartum haemorrhage between the two groups was statistically significant(P<0.05).The visual analogue score(VAS)of the second and third stages of labour in the observation group was lower than that of the control group,and the difference was statistically significant(P<0.05).Comparison of relevant indicators of newborns in the two groups,the difference was not statistically significant(P>0.05).Conclusion The use of total labour analgesia can increase the rate of spontaneous delivery and effectively relieve maternal pain during the whole labour process and reduce the incidence of adverse maternal and infant outcomes,and can be effectively and safely applied to singleton term primigravid women in clinical practice.
