“…It would perhaps have been informative to repeat this questionnaire at the point of infant discharge, when mothers had used the pumps for even longer. Other studies have involved descriptive reports of opinions of pumps by mothers 11 and structured interviewing, 12 and this would be worth pursuing in future studies. However, we considered that the use of Likert-type scales was less onerous to mothers who were often experiencing a considerable degree of stress and anxiety over their infants.…”

Original Research Well Established Mothers of preterm infants are strongly encouraged to express breast milk for their infant, and most neonatal intensive care units recommend double-pumping using an electric pump. Incorporating petal massage cushions into a manual pump has proven benefits for milk expression in this setting. Newly ExpressedAn electric pump incorporating massage cushions showed similar effectiveness to a standard hospital-grade electric pump for milk expression in the neonatal intensive care unit. Similar proportions of infants received breast milk at discharge, but mothers using the novel pump were more likely to be directly breastfeeding. BackgroundThe use of human milk is strongly recommended for preterm infants, 1,2 and an increasing number of mothers aim to provide breast milk for their infant. However, these infants are frequently too immature or sick to breastfeed and mothers may need to express milk for a considerable length of time. Breast pumps rely predominantly on suction to extract milk, which may be unphysiological and is sometimes unpleasant for mothers.3 In recent years, research to improve pump design has focused on the use of compression stimuli 3,4 and different frequency and vacuum patterns. [5][6][7] The Medela Symphony pump (pump S; Medela AG, Baar, Switzerland) Objective: This study aimed to compare the effectiveness of 2 electric pumps: Medela Symphony (pump S) and a novel pump (Philips AVENT Twin electronic pump; pump A). Both offer flexibility of rate and suction; pump A also incorporates petal compression cushions. Primary outcomes were (1) milk weight expressed during 10-day study period and (2) weight of milk expressed in a 15-minute test. Methods: Seventy-one mothers with preterm infants < 34 weeks were randomized. Mothers completed 10-day diaries including weight of milk expressed. Milk weight expressed during a single 15-minute test period and data on pumping mode, skin-to-skin contact, breastfeeding at infant discharge, and mothers' opinions of the pump were recorded. Results: There was no significant difference in milk expressed during the first 10 days between groups. Pump S mothers expressed significantly more milk during a fixed 15-minute period. Mothers using pump A awarded higher scores for certain characteristics of the pump, notably location of control button and ease of use. Similar proportions of infants received breast milk at discharge, but pump A mothers were more likely to be directly breastfeeding (odds ratio, 4.27 [95% confidence interval, 1.29, 14.1]). Conclusion:The breast pumps showed similar effectiveness in terms of milk expression and maternal opinions. The finding that breast pump design may influence breastfeeding at infant discharge merits further investigation.

“…In these cases, maternal education on methods to help the infant open his/ her mouth widely to grasp the areola (150°at the angle of the mouth) is essential [50]. Lactating mothers should be advised to offer the breast as many times as requested by their infants, and use the electric pump if the baby does not empty the breast completely [51]. Side-lying holds, focusing on the areola and nipple may also result in easier latching.…”

Breast cancer is the most common malignant tumor-affecting women during the child bearing period. With the rising trend in delaying pregnancy later in life, the issue of subsequent pregnancy and lactation following breast cancer diagnosis has been more frequently encountered. In this context, data is scarce particularly those addressing the issue of lactation. In this review, we discussed different endocrinal, clinical and biological aspects dealing with breast-feeding after breast cancer in an attempt to determine how safe and feasible this approach is.

“…In addition, using SIM saves the mother time compared with using SEQ, as noted in previous studies. 4,[6][7][8]18 The efficacy of breast expression can be assessed by measuring the total milk yield or, preferably, the percentage of available milk removed. This controls for mothers having vastly different milk productions 10 and for each mother having a different degree of fullness before each pumping session.…”

“…Researchers have attempted to understand whether these techniques differ in efficiency and efficacy, with four studies investigating mothers of premature infants [4][5][6][7] and two studies investigating mothers of healthy term infants. 8,9 Comparing these studies is difficult as the milk expression protocols differ with respect to the duration of each expression session. In addition, the measured outcome variables varied from total milk yield at a single expression session to long-term daily or weekly milk productions.…”

“…Although all studies recommended SIM to be the preferred technique, only one study in each of these populations of women demonstrated a significant increase in milk yield during SIM. 7,8 Previously, efficacy of milk expression has been assessed by overall milk output. However, because mothers and infants vary greatly in their feeding patterns, milk production, and breastmilk storage capacity, 10 the total volume expressed for one mother can be very different from that of another, yet both mothers may have removed a similar proportion of the milk contained in their breasts.…”

Introduction: Simultaneous (SIM) breast expression saves mothers time compared with sequential (SEQ) expression, but it remains unclear whether the two methods differ in milk output efficiency and efficacy. Subjects and Methods: The Showmilk device (Medela AG, Baar, Switzerland) was used to measure milk output and milk ejection during breast expression (electric pump) in 31 Australian breastfeeding mothers of term infants (median age, 19 weeks [interquartile range, 10-33 weeks]). The order of expression type (SIM/SEQ) and breast (left/right) was randomized. Results: SIM expression yielded more milk ejections (p £ 0.001) and greater amounts of milk at 2, 5, and 10 minutes (p £ 0.01) and removed a greater total amount of milk (p £ 0.01) and percentage of available milk (p < 0.05) than SEQ expression. After SIM expression the cream content of both the overall (8.3% [p £ 0.05]) and postexpression (12.6% [p £ 0.001]) milk were greater. During SEQ expression, the breast expressed first had a shorter time to 50% and 80% of the total amount of milk than the breast expressed second (p £ 0.05), but, overall, a similar percentage of available milk was removed from both breasts. Conclusions: SIM expression stimulated more milk ejections and was a more efficient and efficacious method of expression, yielding milk with a higher energy content.
