8.1 Engorgement
Breast fullness
Secretory activation (lactogenesis II) occurs biochemically at about 30 - 48 hours postpartum. 1 2 3 The clinical onset experienced as 'the milk coming-in' is reported to occur around postpartum Day 2 - 3, with wide individual variation (1hr - 6 days) . 4
It's because of the placenta!
Progesterone blocks milk production.5
- progesterone levels fall when the placenta is delivered - no longer inhibiting milk secretion
- prolactin, which is essential to 'make milk' was already in high concentration in the mother's blood stream
- lactose secretion into the alveoli of the breast increases, osmotically drawing in water to increase milk volume 6

Signs and Symptoms
Women report knowing their milk is 'in' by the following signs and symptoms:
- breast tingling
- breast fullness
- milk leakage
- physical appearance of the milk
- change in infant swallowing pattern while feeding, and cues to feed.
Engorgement
- pain and misery for the mother
- blocked ducts
- mastitis
- low milk supply
- premature weaning
...the swelling and distension of the breast, usually in the early days of initiation of lactation, caused by vascular dilatation as well as the arrival of the early milk. 7
Breast engorgement is not an inevitable part of early lactation.
Why does this happen?
- delayed, ineffective or infrequent milk removal => blockage of capillaries and slowed venous return => breast swelling and tissue oedema => difficult milk removal ... and so on.
- breast swelling and tissue oedema (from overhydration with IV fluids in labor) => difficult milk removal => blockage of capillaries and slowed venous return => tissue oedema ...
- I'm sure you 'get the picture' now.
If normal breast fullness progresses to engorgement the signs and symptoms include:
- swollen breasts; tight, shiny skin
- generalized pink or redness of both breasts
- mild to severe pain
- increased heat of both breasts
- difficulty latching baby effectively and achieving milk removal
- mild pyrexia (fever)
Cause
- Milk stasis in the breast
- poorly latched infant, or ineffective suckling
- reduced breastfeeding8
- giving additional fluids to baby, that delay feeding cues
- using pacifiers/dummies to delay feeds
- 'skipping' feeds, particularly night feeds
- not expressing when breastfeeding is ineffective
- Overhydration of IV fluids during labor 9,10
- Low serum albumin11
Prevention

Don't be fooled
Breast fullness is normal. Engorgement is not.
Engorged, painful breasts are not a sign of a good milk supply. It usually indicates that breastfeeding practices have been poorly initiated, and proactive management will be required to retrieve the situation.
Breast engorgement is preventable in most cases.

That's NOT what you want to happen with your new mothers.

Clinical Management
-
Frequent, effective removal of milk
- Encourage the mother to breastfeed her baby often.
- Ensure baby is latched on to breast well.
- Allow the baby to feed as long as he will on one side before offering the other side, optimizing drainage.
- Firm, but gentle massage of lumpy areas while baby feeds helps milk flow. Allow the other breast to drip freely.
- Hand express breastmilk, if necessary.
-
Before feeding: to help baby latch to a very full, firm breast.
A few minutes of expressing milk from around the nipple/areola can make a big difference. Also, after baby has suckled for a minute unlatch him from the breast and relatch - frequently achieving an even deeper, more effective and more comfortable latch.
-
After feeding: If breasts still uncomfortably tight, express enough to achieve comfort.
This should be done after and between feeds as often as necessary.
If baby does not breastfeed on the second side, hand express milk from that side until comfortable to prevent engorgement getting worse.
-
Before feeding: to help baby latch to a very full, firm breast.
- When breasts are particularly full stimulate a milk ejection by gentle massage or a warm compress. Apply gentle compression anywhere on the breast with the palm of the hand. This gentle pressure may help the milk flow freely from the nipple without having to hand express when the mother is experiencing a lot of pain.
- Encourage the mother to breastfeed her baby often.

Will expressing increase milk production?
Until engorgement is resolved:
- breastfeed to meet the infant's needs (effectively and frequently)
- if breast/s still uncomfortably full, hand express until comfortable (not empty!)
- between feeds when breasts uncomfortably full, hand express until comfortable (not empty!)
As venous congestion reduces and the infant's needs increase, additional milk removal will not be required and the breast will tailor milk production to the infant's needs.
Reassure the mother that this management will assist faster resolution of her engorgement. Failure to diligently attend to these strategies will prolong the discomfort, initiate involution and risk low breastmilk supply.

Reduce tissue swelling
- A Cochrane Review of management of breast engorgement 15 found:
- There is no difference between treatment with cold packs or cabbage leaves. Both were equally effective in relieving pain but there was no strong evidence that interventions resolved symptoms faster than with no treatment.
- Acupuncture gave greater improvement in symptoms in the days immediately after the treatment.
- The underlying principle for the use of cold is to initiate vasoconstriction, decreasing venous congestion and reducing interstitial oedema.
- Depending on degree of engorgement, the cold compresses may need to be replaced frequently (e.g. 20 mins on, 20 mins off and repeat several times)
- Apply cold compresses to both breasts immediately after breastfeeding/expressing.
- Certain non-steroidal anti-inflammatory drugs are very effective. 15
- A Cochrane Review of management of breast engorgement 15 found:

Heat or cold?
Cold reduces the blood flow to the breast reducing swelling (interstitial fluid causing edema flows away from breast via lymphatic system).
Mothers usually prefer the feeling of cold on their hot breasts, but it is important to individualise your management and be responsive if a mother finds this to be unpleasant.

Unit Activity
Revise your unit's policy on the management of engorgement. Develop a teaching plan for a 15-minute educational session you could lead on the prevention and management of engorgement for your colleagues.
Advanced care
Areolar oedema/edema
When breast engorgement is so severe that the areolar is edematous, latching the baby onto the breast for effective breastfeeding is impossible. Methods have been described to assist the movement of this interstitial fluid to make latching possible. 11,9

Share this paper with your colleagues who may be working with women experiencing this type of engorgement. Ask the mothers about their feelings of the usefulness of this technique. When you are proficient at it you will be able to describe its application over the phone to mothers in difficulty at home.
Additional strategies include
- lie mother on her back and using a light, stroking movement massage the breast away from the nipple, towards the axilla; aiding lymphatic drainage
- baby has to be ready to feed immediately after massage because the fluid will return very quickly
- hand express if baby not available to suckle. DO NOT use a breast pump ... this increases the edema.
Overactive milk production
Full drainage and block feeding may be the solution.18
