Q

What uterine changes occur during the puerperium?

A

    -uterine weight decreases

A

This is the first
milk a breastfed baby receives and is more protein and vitamin rich than later milk produced by
the mother. Colostrum is essential for early immunological protection to the newborn.

Q

What is the let-down reflex and how does it work?

A

The let-down reflex refers to the mechanism of milk release from the breast during feeding.

In response to suckling (or alcohol, pain, the cry of a baby), oxytocin is stimulated and released from the posterior pituitary which in turn stimulates the myoepithelial cells which surround the breast alveoli to contract which squeezes breast milk out of the breast alveoli and nipple

Q

How can improper breastfeeding technique lead to lactational mastitis?

A

Trauma to the breast and subsequent milk stasis and ineffective milk release make the breast
more likely to harbour bacteria and therefore be more prone to infection.

Q

What topics should be included in a focused breast history in someone with suspected mastitis?

A
  • Milk stasis (decreased milk output)
  • Possible abscess (tender lump)
  • Symptoms related to possible breast inflammation (e.g., warmth, pain, swelling,
    firmness, erythema)
  • Nipple discharge, which may be present with mastitis and occurs more often with duct
    ectasia (dilated ducts with inflammation); however, purulent discharge is usually
    indicative of breast infection
  • Systemic symptoms of infection (fever, malaise, myalgia)”
