Mothers of preterm infants are at risk for inadequate milk production. Pumping logs are often used to both encourage lactation in the first week and track its efficacy. Our objectives were to determine whether mothers of preterm infants who keep pumping logs are demographically different from those who do not and to determine whether this practice affects the amount of mother's own milk (MOM) fed to their infants. We also aimed at determining whether there is a correlation between: (1) time to first breast milk expression, (2) cumulative frequency of expression in the first week, and (3) milk volume on day 7 with subsequent milk volumes and percent of infant diet consisting of MOM. Mothers of infants born ≤32 weeks and ≤1,500 g were enrolled within 48 hours of birth and encouraged to keep a pumping log. Data were collected on maternal characteristics, patterns of milk expression, and milk volumes on days 7, 14, 21, and 28 after delivery. Infant data were collected via chart review. Mothers who kept pumping logs provided their own milk for a greater percentage of their infant's feeds at the time of achieving full feeds ( = 0.017). The total number of expressions in the first week was correlated with milk volume on day 21 ( = 0.016) and the provision of a higher percentage of MOM feeds at discharge ( = 0.03). Milk volume on day 7 correlated with volumes obtained at days 14, 21, and 28 ( < 0.001). Pumping logs may affect the availability of MOM for preterm infants. Frequency of pumping in the first week and milk volume on day 7 may impact long-term lactation success for these women.
早产儿的母亲存在乳汁分泌不足的风险。泵奶记录通常用于在第一周内促进泌乳并跟踪其效果。我们的目的是确定记录泵奶情况的早产儿母亲在人口统计学方面是否与不记录的母亲有所不同，以及这种做法是否会影响她们喂养婴儿的自身母乳（MOM）量。我们还旨在确定以下因素之间是否存在相关性：（1）首次母乳表达的时间，（2）第一周内表达的累积频率，以及（3）第 7 天的奶量与随后的奶量以及婴儿饮食中 MOM 的百分比之间的关系。出生时胎龄≤32 周且体重≤1500g 的婴儿的母亲在出生后 48 小时内入组，并鼓励其记录泵奶情况。收集的数据包括母亲的特征、泵奶模式以及产后第 7、14、21 和 28 天的奶量。通过病历回顾收集婴儿数据。记录泵奶情况的母亲在达到全量喂养时，为婴儿提供自身母乳的比例更高（=0.017）。第一周内的总泵奶次数与第 21 天的奶量相关（=0.016），与出院时提供更高比例的 MOM 喂养相关（=0.03）。第 7 天的奶量与第 14、21 和 28 天的奶量相关（<0.001）。泵奶记录可能会影响早产儿获得 MOM 的情况。第一周内的泵奶频率和第 7 天的奶量可能会影响这些女性的长期泌乳效果。
