目的:探讨分阶段刺激泌乳模式在母婴分离过程中对产妇泌乳Ⅱ期时间和泌乳量的影响。方法:采用便利抽样法，选择2019年1—12月在复旦大学附属妇产科医院产科分娩且母婴分离的产妇140名为研究对象，将其随机分为观察组和对照组，各70名。对照组采用常规护理，观察组由护理人员基于分阶段刺激泌乳模式进行干预，比较两组的泌乳Ⅱ期时间、泌乳量以及乳房肿胀程度。结果:产后48、72 h两组产妇泌乳Ⅱ期人数差异有统计学意义（n P<0.05）。观察组产妇产后24、48、72 h泌乳量均高于对照组，差异有统计学意义（n P<0.01）。两组产妇产后72 h乳房肿胀程度差异有统计学意义（n P<0.01）。n 结论:分阶段刺激泌乳模式能提前母婴分离后产妇泌乳Ⅱ期时间，增加产妇泌乳量以及减轻乳房肿胀程度。“,”Objective:To explore the effect of stimulation lactation model by stages on the time of lactation period Ⅱ and lactation volume in delivery women during maternal separation period.Methods:Using the convenience sampling method, 140 cases of delivery women in the Obstetrics Department of the Obstetrics and Gynecology Hospital of Fudan University from January to December 2019 were selected as the research objects. All objects were randomly divided into observation group and control group, with 70 cases in each group. Control group carried out routine nursing, and observation group implemented intervention by nursing staff based on the stimulation lactation model by stages. The time of lactation period Ⅱ, lactation volume and breast swelling were compared between two groups.Results:There were statistically significant differences in the number of delivery women in lactation period Ⅱ between two groups at 48 and 72 hours after delivery (n P<0.05) . The lactation volume of delivery women in observation group was higher than that of control group at 24, 48 and 72 hours after delivery, and the differences were statistically significant (n P<0.01) . There was a statistically significant difference in the degree of breast swelling of delivery women between two groups at 72 hours after delivery (n P<0.01) .n Conclusions:Stimulation lactation model by stages can advance the time of lactation phase Ⅱ after maternal separation, increase maternal lactation volume and reduce breast swelling.
