Pump-dependent mothers of preterm infants commonly experience insufficient production. We observed additional milk could be expressed following pumping using hand techniques. We explored the effect on production of hand expression of colostrum and hands-on pumping (HOP) of mature milk.
A total of 67 mothers of infants <31 weeks gestation were enrolled and instructed on pumping, hand expression of colostrum and HOP. Expression records for 8 weeks and medical records were used to assess production variables.
Seventy-eight percent of the mothers completed the study. Mean daily volumes (MDV) rose to 820 ml per day by week 8 and 955 ml per day in mothers who hand expressed >5 per day in the first 3 days. Week 2 and/or week 8 MDV related to hand expression (P<0.005), maternal age, gestational age, pumping frequency, duration, longest interval between pumpings and HOP (P<0.003). Mothers taught HOP increased MDV (48%) despite pumping less.
Mothers of preterm infants may avoid insufficient production by combining hand techniques with pumping.
依赖于输液泵的早产儿母亲通常会出现乳汁分泌不足的情况。我们发现，使用手部技术进行泵吸后，可以额外挤出乳汁。本研究旨在探讨手挤初乳和手挤奶（HOP）对成熟奶产量的影响。
共纳入 67 名孕周<31 周的婴儿的母亲，并对其进行泵吸、手挤初乳和 HOP 的指导。通过 8 周的记录和医疗记录来评估产奶量的变化。
78%的母亲完成了研究。到第 8 周时，平均日产量（MDV）上升至 820 毫升/天，而在最初 3 天内每天手挤奶>5 次的母亲中，MDV 达到了 955 毫升/天。第 2 周和/或第 8 周的 MDV 与手挤奶（P<0.005）、母亲年龄、胎龄、泵吸频率、时长、最长泵吸间隔和 HOP 有关（P<0.003）。尽管泵吸量减少，但接受 HOP 教学的母亲的 MDV 增加了（48%）。
通过将手部技术与泵吸相结合，早产儿的母亲可能可以避免乳汁分泌不足的情况。
