BackgroundBreastfeeding is essential for infants and mothers. Epidural labor analgesia is used frequently to alleviate pain during vaginal delivery. Studies have found that epidural labor analgesia potentially have negative effects on postpartum breastfeeding. However, the efficacy of epidural labor analgesia on early breastfeeding after vaginal delivery is unclear. Therefore, a retrospective analysis was performed to illuminate the efficacy of epidural labor analgesia on postpartum breast feeding.MethodsA total of 392 women who received vaginal delivery in the Second People's Hospital of Foshan from July 2022 to June 2023 were selected for this study, and all women received epidural labor analgesia and were divided into three groups according to the efficacy of labor analgesia. There were three groups: parturients with VAS scores < 3 were divided into Group E (n = 192), parturients with VAS scores 4-6 were divided into Group M (n = 127), and parturients with VAS scores > 7 were divided into Group P (n = 73). The labor process, lactation initiation time, and incidence of delayed onset of lactation were analyzed. The lactation volume and time and LATCH score at 24, 48 and 72 h after vaginal delivery were also analyzed.ResultsThere was no significant difference in labor process times among the three groups (P > 0.05). The cases of prolactin use in Group M were less than those in Group E and Group P, with a significant difference (all P < 0.05). There was no significant difference in cases of prolactin use between Group E and Group P (P > 0.05). The lactation initiation time in Group M was significantly shorter than those in Group E and Group P (all P>0.05). There was no significant difference in lactation initiation time after vaginal delivery between Group E and Group P (P>0.05). The incidence of delayed onset of lactation in Group M was significantly lower those that in Group E and Group P (all P < 0.05). There was no statistically significant difference in the incidence of delayed onset of lactation between Group E and Group P (P > 0.05). The lactation volumes at 24, 48 and 72 h after vaginal delivery in Group M were significantly higher than those in Group E and Group P (all P < 0.05). There was no significant difference in lactation volume at 24, 48 and 72 h after vaginal delivery between Group E and Group P (P > 0.05). The lactation times at 24, 48 and 72 h after vaginal delivery in Group M were significantly higher than those in Group E and Group P (all P < 0.05). There was no significant difference in lactation times at 24, 48 and 72 h after vaginal delivery between Group E and Group P (P > 0.05). There was no significant difference in LATCH scores at 24, 48 and 72 h after vaginal delivery among the three groups (all P > 0.05).ConclusionsCompared with labor analgesia with excellent and poor analgesia efficacy, labor analgesia with moderate analgesia efficacy has fewer cases of prolactin use, more lactation volume and time, a shorter lactation initiation time, a lower incidence of delayed onset of lactation and no effect on the LATCH score of breastfeeding.© 2023.
