  1. Breast Milk QI March 09, 2017

  2. Objectives • Overview of Maternal Human Milk • Components • Differences • Best NICU practices

  3. Colostrum • Stimulates rapid growth in GI mucosa (if first feeding) • Use for trophic feedings • Use in order it is produced • High concentrations of • Protective secretory IgA • Growth factors (EGF, TGFß) • Lactoferrin • Anti-inflammatory cytokines • Oligosaccharides • Concentration of most protective components inversely proportional to gestational age

  4. Lactoferrin • High antimicrobial and antifungal properties • Eradicates ingested pathogens • Blocks adherence of bacteria to gut endothelium • Binds endotoxin • Binds iron that may support microbe growth • Growth promoting • Anti-inflammatory

  5. Preterm milk vs. Term milk • Increased • Protein • Immune factors • Fats • Calories • Growth factors

  6. Donor milk vs. Maternal breast milk • Pasteurized • Rapid heating, maintain temp constant, then rapid cooling • 62.5 C for 30 min (Holder pasteurization method) • Unchanged components • Most free amino acids • Many growth factors (EGF, TGFß1,2) • Most polyunsaturated, monounsaturated, and saturated fatty acids • Total lipid content • Fat soluble vitamins • Oligosaccharides (prebiotic effects)

  7. Donor milk vs. Maternal breast milk • Increased components • GM-CSF • Lactulose • Some amino acids (leucine, arginine, glutamine) • Reduced components • IgA, IgM, IgG • Lactoferrin • Lysozyme • IGFs • Water soluble vitamins • Effect unclear • IgG subcomponents • Cytokines

  8. Donor milk • Decreased rates of NEC, CLD as compared to preterm formula • Bovine milk fortifiers possible negative effect on this reduction unclear • Slower growth rate (vs. formula) • Overall decreased morbidities with mother’s own milk vs. donor milk

  9. Education on Maternal Breast Milk • Share the scientific evidence with mothers • Decreased rates of Necrotizing Enterocolitis • Decreased Late Onset Sepsis • Improved Neurodevelopmental Outcomes • Different stages of Lactation

  10. Considerations during NICU stay • Amounts and time periods of human milk feeding • Feeding history throughout NICU stay • May be more important than “breast milk feeding at discharge” • Most important period is the first 30-60 days • Exclusive breast milk vs. formula during this time period • Daily dose and exposure period • Think percentages and days • Growth • Formula fed infants grow faster than breast milk fed infants (but why?) • How much volume does baby actually take in breast feeding • Differing caloric content between feeds (not all feeds 20 calorie) • Inadequate protein?

  11. Best NICU Practices • Encourage mother to provide milk for her infant • Lactation support for families and NICU staff • Prioritizing initiation, establishment and maintenance of maternal milk volumes • Lactation technologies to manage human milk feeding problems

  12. Encourage mother to provide milk • Mothers and families rely on provider education on breast milk • Independent of social and ethnic backgrounds • Research does not indicate breast milk promotion makes mothers feel “guilty” • Focus on providing milk for VLBW (short-term and intermediate-term pumping) rather than long-term goal of breast feeding

  13. Lactation Support for Families/NICU Staff • Cost-effective • Provide evidence-based guidance • Lactation and NICU providers/nursing staff must resolve inconsistencies prior to talking with parents • Standardize policies and procedures based on evidence • NICU lactation programs should be under guidance of APN, dietitian or neonatologist • Become knowledgable in inititation, establishment and maintenance of volume in pump-dependent mothers

  14. Lactation Support for Families/NICU Staff • Physical resources • Hospital grade dual electric breast pump • Pump kit and instruction for adequate milk removal • Volume-based containers for storing expressed milk • Colostrum (11 ml) • Breast milk (60 ml) • Refrigerator and freezer space for on-site milk storage • Custom-fitted breast shields to promote milk transfer • Infant scales to perform test weights • Research shows more cost-effective than donor milk or formula feedings during hospital stay

  15. Lactation Support for Families/NICU Staff • Non-physical resources • 24 hour access to infant • Skin-to-skin holding (kangaroo care) • Daily “tasting” of milk (suckling at emptied breast) after extubation • Review of maternal milk volume records at least twice weekly • Identify pumping patterns • Detect and treat potential problems • Non-pharmacological and pharmacological interventions • Observation of mothers using pump in NICU at least once weekly • Detection and treat problems • Technique • Incorrectly fitted breast shields • Complete breast emptying

  16. Breastfeeding peer counselors • Breastfeeding peer counselors • Can assist lactation consultants and teach mothers how to • Use breast pumps • Clean collection Kit • Collect, label, store, transport milk • Cultural and Ethnic training • Often preferred to health care professional by mothers • Empower mothers

  17. Prioritizing initiation, establishment and maintenance of maternal milk volumes • Most important lactation priority • Mothers are breast-pump dependent if infant VLBW • May experience delayed lactogenesis, inadequate milk volume • Consideration factors • Doesn’t rely on infant stimulus for “coming to volume” • Ineffective breast pump • Improperly fitting nipple shields • Infrequent pump use • Ending pumping session prior to all available milk removed • Stress, fatigue and down-regulation of prolactin • Post-birth contraceptive management • Need volume targets and daily monitoring • At least 350 ml/day by end of 2nd week • Higher volumes (500 to 1000 ml per day) more desirable

  18. Lactation technologies • To diagnose and manage NICU problems • Crematocrit • Lipid and caloric concentration of expressed human milk • Uses hematocrit centrifuge with capillary tube • Test-weights

  19. Considerations after NICU discharge • Balancing short-term growth and versus long-term outcomes • Breast milk • Higher IQ scores • Less infections • Less eczema • Less adult morbidities
