Duration of breast milk expression among working mothers enrolled in an employer-sponsored lactation program.

BACKGROUND: Maternal employment has been one of the greatest barriers to breastfeeding. Women are increasingly solving this problem by expressing milk at work and taking it home to their infants. PURPOSE: The objective was to determine duration of breast milk expression among working mothers enrolled in an employer-sponsored lactation program. DESIGN AND METHODS: Retrospective reviews were conducted on the lactation records of 462 women employed by 5 corporations in order to describe and characterize their experiences. The lactation program included the employees' choice of (a) a class on the benefits of breastfeeding; (b) services of a certified lactation consultant (CLC); and (c) private room in the workplace with equipment for pumping. RESULTS: Breastfeeding was initiated by 97.5% of the participants, with 57.8% continuing for at least 6 months. Of the 435 (94.2%) who returned to work after giving birth, 343 (78.9%) attempted pumping milk at work, and 336 (98%) were successful. They expressed milk in the workplace for a mean of 6.3 months (SD = 3.9, range 2 weeks to 21 months). The mean age of infants when the mothers stopped pumping at work was 9.1 months (SD = 4.1, range 1.9 to 25 months). Most of the women who pumped their milk at work were working full time (84.2%). The mean postnatal maternity leave was 2.8 months. The proportion of women who chose to pump at work was higher among women who were salaried than among those who were paid hourly wages (p < 0.01). CONCLUSIONS: Company-sponsored lactation programs can enable employed mothers to provide breast milk for their infants as long as they wish, thus helping the nation attain the Healthy People 2010 goals of 50% of mothers breastfeeding until their infants are 6-months-old.

Plasma and red blood cell fatty acids of low-birth-weight infants fed their mother's expressed breast milk or preterm-infant formula.

The fatty acid composition of plasma phospholipids, red blood cell (RBC) phosphatidylcholine (PC), and phosphatidylethanolamine (PE) was determined for low-birth-weight (LBW) infants when full oral feeding commenced (day 0) and after a further 28 d (day 28). They were fed their mother's expressed breast milk (PTM, n = 9), formula (SCF, n = 16) with 2% 18:3n-3 fatty acids, 20% 18:2n-6 fatty acids, or a combination of SCF and PTM (n = 11). Concentrations of all 20- and 22-carbon n-6 and n-3 fatty acids were similar among the infant groups on days 0 and 28 (mean postnatal age 42 +/- 1.3 d). The results suggest that formula with greater than or equal to 2% 18:3n-3 and a ratio of 18:2n-6 to 18:3n-3 similar to that of human milk may permit incorporation of n-3 fatty acids in LBW infant tissues equivalent to that from human milk.

Circadian variations in fat content of expressed breast milk from mothers of preterm infants.

BACKGROUND: Little is known about circadian variations of the fat content in expressed human milk by mothers of preterm infants. OBJECTIVE: To test the hypothesis that the fat content of expressed preterm human milk is higher in samples expressed in the evening (i.e. after 3 daily meals) than in the morning (after a night-long fast). METHODS: We collected samples of expressed human milk obtained from 39 mothers of hospitalized growing preterm infants aged 7-14 days, with a gestational age at birth ranging from 26 to 33 weeks, who routinely expressed all their milk every 3 hours, during the day time, just before bed time, and as soon as they woke up, using a commercial breast pump (Medela AG, Baar, Switzerland). One sample was obtained from the first morning expression (between 0600 and 0900) and the second from the evening expression (between 2100 and 2400). The entire quantity of expressed milk was collected, mixed and measured in a capillary tube after centrifugation at 9000 rpm for 5 minutes. Creamatocrits (CMT) were performed in duplicates. Each sample was read independently by 2 investigators who were not aware of the origin and time of sampling and the results were averaged. Results are expressed as mean +/- SD, and analyses were by paired t-test and regression analysis. RESULTS: CMT was significantly higher in evening than in morning samples (7.9 +/- 2.9% vs. 6.6 +/- 2.8%, P = 0.005). Neither CMT nor the morning-evening difference in CMT correlated with gestational age or birthweight. The morning CMT correlated significantly with the evening CMT (P < 0.001). CONCLUSIONS: There are significant circadian variations in the CMT of expressed preterm human milk. We speculate that if higher caloric content of expressed human milk is needed in a specific preterm infant, evening sample, if available, should be used preferentially.

Application of Hazard Analysis Critical Control Point (HACCP) to the handling of expressed breast milk on a neonatal unit.

Hazard Analysis Critical Control Point (HACCP) is a powerful procedure for ensuring quality and safety and has gained widespread use in industry. This paper describes the basic method which is a four-stage process including process analysis, hazard identification, identification of critical control points and devising effective control options. Suggestions as to how the method can be adapted to the control of hospital infection are made. A HACCP analysis, on the supply of expressed human breast milk to babies on a Special Care Baby Unit, is presented. Although only the mother's own milk was given to babies on the unit, several potential hazards were identified and suggestions have been made for their control.

Comparison of sucrose, expressed breast milk, and breast-feeding on the neonatal response to heel prick.

Newborns endure many heel pricks and other uncomfortable procedures during their first hospital stay. The aim of this study was to investigate the effectiveness of breast-feeding in reducing pain in newborns undergoing heel prick tests. One hundred thirty healthy term infants requiring a heel prick blood sampling for the Guthrie test were studied. Infants were randomly allocated to 1 of the following treatment groups: group 1, 25% sucrose (n = 35); group 2, breast milk (n = 33); group 3, sterile water (n = 34); and group 4, breast-feeding (n = 28). The median values of crying and recovery time and percent change in heart rate at 1, 2, and 3 minutes were recorded. A behavioral pain scale was applied according to the infant body coding system. The median crying time was 36, 62, 52, and 51 seconds in groups 1, 2, 3, and 4, respectively (P =.002). Similarly, there was a significant overall difference among groups for the duration of recovery time (P =.006) and the percent change in heart rate at 1 (P =.03), 2 (P =.01), and 3 (P =.009) minutes favoring the sucrose group. But when we compared the groups, the significance remained for the sucrose versus breast milk (P =.007) and water (P =.001) groups for the recovery time and sucrose versus all other groups for the percent change in heart rate at 3 minutes. The infant body coding system showed that babies in the sucrose group had significantly lower scores followed by the breast-fed and breast milk groups (P =.0001). Our study revealed that 25% sucrose is superior to breast-feeding in pain relief, which is reflected mainly in crying time and behavioral variables. The behavioral effects of breast-feeding did not provide any additional benefit.

Analgesic effect of expressed breast milk in procedural pain in neonates.

UNLABELLED: Prevention, treatment and assessment of neonatal pain have been of major clinical and scientific interest the last decades. Non-pharmacological interventions such as sweet oral solutions are successful in pain relief. Whether breast milk, with its lactose content of 7%, has any effect on the prevention of pain has been debated. CONCLUSION: Randomized studies of breast milk in prevention and treatment of neonatal pain are needed.

Necrotising enterocolitis in the very low birthweight infant: expressed breast milk feeding compared with parenteral feeding.

The incidence of necrotising enterocolitis (NEC) in very low birthweight infants (VLBW less than or equal to 1500 g) was reduced by the delayed onset of enteral feeding. Eight (18%) out of 44 VLBW infants who were in hospital during the first year of the study developed NEC. During the next 12 months 85 similar infants were initially fed by parenteral nutrition only, and then from age 14-21 days with infant formula. During the second year only 3 (3%) patients developed NEC. There were no other relevant changes in management. Throughout the entire study, the onset of NEC in each infant in whom it occurred was after the start of enteral feeding. We recommend avoiding enteral feeding in VLBW infants during the period that they are particularly vulnerable--namely the first 2 or 3 weeks of life.
