The objective of this study was to compare the effectiveness, efficiency, comfort and convenience of newly designed breast pump suction patterns (BPSPs) that mimic sucking patterns of the breastfeeding human infant during the initiation and maintenance of lactation.
In total, 105 mothers of premature infants ≤34 weeks of gestation were randomly assigned to 1 of 3 groups within 24 h post-birth. Each group tested two BPSPs; an initiation BPSP was used until the onset of lactogenesis II (OOL-II) and a maintenance BPSP was used thereafter.
Mothers who used the experimental initiation and the standard 2.0 maintenance BPSPs (EXP-STD group) demonstrated significantly greater daily and cumulative milk output, and greater milk output per minute spent pumping.
BPSPs that mimic the unique sucking patterns used by healthy-term breastfeeding infants during the initiation and maintenance of lactation are more effective, efficient, comfortable and convenient than other BPSPs.
本研究旨在比较模仿母乳喂养婴儿在泌乳启动和维持阶段吸吮模式的新型吸乳器吸乳模式（BPSP）在有效性、效率、舒适度和便利性方面的差异。
共有 105 名早产儿 ≤34 孕周的母亲在出生后 24 小时内随机分配到 3 个组中的 1 个。每个组测试两种 BPSP；一种启动 BPSP 用于直至泌乳二期开始（OOL-II），之后使用维持 BPSP。
使用实验性启动和标准 2.0 维持 BPSP（EXP-STD 组）的母亲，每日和累积奶量显著增加，且每泵奶分钟奶量增加。
在泌乳启动和维持阶段模仿健康足月母乳喂养婴儿独特吸吮模式的 BPSP 在有效性、效率、舒适度和便利性方面优于其他 BPSP。
