To determine whether exclusively pumping mothers of preterm infants could achieve full milk production while using the Ameda Platinum breast pump the first 14 days postpartum.
Twenty-six mothers who delivered infants between 26 and 32 weeks' gestation at 2 Intermountain Healthcare hospitals completed the study. Mothers could not take milk-enhancing or milk-reducing substances, feed directly at the breast, have had breast surgery, or use any other breast pump during the study.
Nonexperimental, descriptive study.
Mothers were instructed to use the Ameda Platinum breast pump exclusively 8 times daily, for 14 days. They recorded milk volumes, suction pressures, cycle speeds, and time spent pumping. A "Performance Questionnaire" was completed at the end of the study with questions about the ease of use, preferred speed and suction settings, and overall performance of the pump.
Full milk production was defined as 700 mL/d. Speed and suction settings, as well as average pumping session length, were analyzed in relation to categories of maximum milk volumes expressed.
The average maximum daily milk volume for all mothers was 817 mL/d. Sixteen mothers produced milk volumes more than 700 mL/d and 9 of these mothers were able to express more than 1000 mL/d. Those with daily milk production more than 700 mL/d used lower suction pressure settings to stimulate the milk ejection reflex and to empty the breast. These higher-producing mothers also chose ending speeds of 50 to 60 cycles per minute, similar to the nutritive sucking pattern of a healthy newborn. Mothers producing less than 500 mL/d used higher suction pressures, faster ending cycle speeds, and longer pumping times. Suction pressures varied widely among all of the mothers and were influenced by the mothers' nipple or breast sensitivity, which varied from mother to mother and day to day. Mothers reported liking separate controls for speed and suction and used them to achieve maximum comfort and milk volume.
The Ameda Platinum breast pump is an effective hospital-grade pump for exclusively pumping mothers to establish full milk production by 14 days postpartum. Separate control of speed and suction allows mothers a wide range of options to achieve greater comfort and multiple milk ejections, both of which contribute to optimal milk expression.
确定早产婴儿的纯吸乳母亲在产后头14天使用美德乐白金吸乳器时能否实现充足的乳汁分泌量。
在2家山间医疗保健医院分娩孕周为26至32周婴儿的26名母亲完成了该研究。母亲在研究期间不得服用增加乳汁或减少乳汁的物质，不得直接进行亲喂，不得有过乳房手术，也不得使用任何其他吸乳器。
非实验性描述性研究。
指导母亲每天仅使用美德乐白金吸乳器8次，共14天。她们记录乳汁量、吸力压力、循环速度和吸乳时间。在研究结束时完成一份“性能问卷”，其中包含关于使用便利性、偏好的速度和吸力设置以及吸乳器整体性能的问题。
充足的乳汁分泌量定义为700毫升/天。根据所表达的最大乳汁量类别分析速度和吸力设置以及平均吸乳时段长度。
所有母亲的平均每日最大乳汁量为817毫升/天。16名母亲的乳汁分泌量超过700毫升/天，其中9名母亲能够挤出超过1000毫升/天的乳汁。那些每日乳汁分泌量超过700毫升/天的母亲使用较低的吸力压力设置来刺激喷乳反射并排空乳房。这些乳汁分泌量较高的母亲还选择每分钟50至60次循环的结束速度，这类似于健康新生儿的营养性吸吮模式。乳汁分泌量少于500毫升/天的母亲使用较高的吸力压力、较快的结束循环速度和较长的吸乳时间。所有母亲的吸力压力差异很大，并且受到母亲乳头或乳房敏感度的影响，这种敏感度在母亲之间以及每天都有所不同。母亲们表示喜欢速度和吸力的单独控制，并利用它们来实现最大舒适度和乳汁量。
美德乐白金吸乳器是一款有效的医院级吸乳器，可帮助纯吸乳母亲在产后14天内实现充足的乳汁分泌量。速度和吸力的单独控制使母亲有广泛广泛广泛更多选择，以实现更大的舒适度和多次喷乳，这两者都有助于实现最佳的乳汁挤出效果。
