Introduction to Breastfeeding Based on a powerpoint by Anita Bordoloi, MD given February 14, 2012
AAP Policy The American Academy of Pediatrics (AAP) recommends that babies be exclusively breastfed for the first 6 months of life.
United States Preventative Services Task Force (USPSTF) The USPSTF recommends interventions during pregnancy and after birth to promote and support breastfeeding.Grade: B Recommendation.
Breast milk • Species-specific • Bio-active • Composed of: • Immunoglobulins (especially IgA) • Growth modulators • Protein • Carbohydrates • Minerals • Vitamins • Fats
Lactation • Cyclical process of milk synthesis and secretion • Activated by prolactin, oxytocin, TSH, and human placental lactogen(hPL) • Prolactin: milk production • Oxytocin: milk secretion • Inhibited by progesterone and estrogen
Prolactin • Initiates milk production • Elicited by suckling • Produced by anterior pituitary gland • Stimulates mammary glandular ductal growth and epithelial cell proliferation
Oxytocin • Milk ejection or letdown • Suckling activates touch receptors that stimulate dorsal root ganglia via intercostal nerves (4, 5, 6) to release oxytocin in a pulsatile fashion • Secreted by posterior pituitary gland • Causes contraction of myoepithelial cells that line the ducts of the breast
Can breastfeeding act as contraception? • Moderate contraceptive effect • Dependent on suckling intensity and frequency • Equivalent to OCP (98%) only in amenorrheic women who exclusively breastfeed at regular intervals for first 6 months • With menstruation or after 6 months, chance of ovulation increases • Supplemental feeding increases chance of ovulation
Other contraceptives and effect on breastfeeding • Intrauterine contraception • Does not affect milk volume or composition • Progestin-only contraceptives • Historically preferred method of hormonal contraception • Does notaffect milk volume or composition • Estrogen-progestin contraceptives • Traditionally thought to suppress milk production • Recent study shows no effect on breastfeeding duration or infant growth
Breastfeeding and Contraception • Double-blind RCT examining the effect of progestin-only compared with combined hormonal contraceptive pillson rates of breastfeeding continuation • Similar breastfeeding continuation rate at 8wks, contraceptive continuation, and infant growth parameters
Benefits of Breastfeeding - Infant Death SIDS Infectious disease Diabetes Obesity Hypercholesterolemia Asthma Atopy Lymphoma/leukemia/ Hodgkin’s disease Cognitive development
Case-control study examining association between breastfeeding and postneonatal death, N=1204 • Ever breastfed, OR 0.79 • Longer breastfeeding associated with lower risk • Decreased incidence of infectious cause (OR 0.76), injury (OR 0.59), and SIDS (0.84)
Benefits of Breastfeeding - Maternal Postpartum bleeding Menstrual blood loss Risk of Breast CA Risk of Ovarian CA Risk of osteoporosis and hip fractures (post-menopausal) Type 2 DM Postpartum depression Postpartum weight loss
Benefits of Breastfeeding - Community Annual healthcare costs in United States Cost for public health programs, i.e. WIC Parental employee absenteeism Environmental burden
Contraindications • Maternal active, untreated TB • Maternal HTLV+ • Maternal HIV (developed countries) • Maternal HSV lesions on breast • Maternal exposure to radioactive materials • Mothers receiving anti-metabolites or chemotherapy • Maternal drug use • Classic galactosemia
NOT Contraindications • Maternal +HepBsAg • Maternal Hepatitis C • Maternal seropositive CMV carriers • Febrile mothers • Mothers exposed to low-level environmental chemical agents • Maternal tobacco use • Maternal alcohol use – wait 2 hours
Keys to Successful Breastfeeding • The sooner, the better • Relaxed and supportive environment • Father’s assistance and support
Keys to Successful Breastfeeding • Positioning the infant • Cradle hold (most common) • Football hold
Keys to Successful Breastfeeding • Presenting the breast • Hand positions: • C-hold or palmar grasp • Scissor grasp • Ensure nipple is not tipped upward
Keys to Successful Breastfeeding • Achieving latch-on • Suck-swallow pattern • Bring nipple towards infant’s mouth
Keys to Successful Breastfeeding • Timing • 8-12 times a day during the first 4-5 days • Unrestricted breastfeeding based on infant’s demand
Insufficient milk supply • Solutions: • Frequent breastfeeding every 1.5-2 hours during the first few days • Galactogogues(milk production enhancers): • Herbal: fenugreek, fennel seeds, milk thistle, goat’s rue • Medical: Reglan, Domperidone
Breast Engorgement • Solutions: • Frequent breastfeeding • Manual expression, breast massage • Cool compresses or ice (to relieve pain) • Frequent warm showers (to express milk) • Mild analgesics • Manual or electric pumping • +/- Cabbage leaves (to relieve pain)
Nipple pain • Sore nipples: due to improper latching • Encourage mother to place areola/nipple in infant’s mouth • Cracked nipples • Begin breastfeeding on less-affected side • Place a drop of milk on each nipple and allow to air-dry after breastfeeding • High-grade lanolin or nipple shields • Avoid coarse fabric, bras w/ seams
Mastitis • More common in engorged breasts • Presents with flu-like symptoms • Most common pathogens: S. aureus, streptococcus, E. coli • Treatment: ibuprofen, dicloxacillin, cephalexin, clindamycin • Continue to breastfeed while taking antibiotics • Frequent emptying
Breast Abscess • Rare – incidence of 0.1% • Requires incision and drainage, antibiotics • Pump affected side • Continue to breastfeed on unaffected side
