Improperly collected or stored breast milk can become contaminated and cause sepsis
Staff must adhere to local policies on collection of human milk and hand washing
Staff must adhere to local policies on collection of human milk and hand washing
ADMINISTRATION
- Ensure there is a dedicated fridge and freezer for milk storage on ward
- Add date and time bottles removed from freezer/opened to bottle label
- Ensure 2 person check before administration to baby and/or addition of additives
ADVICE TO MOTHERS
- See Breast milk expression guideline
- Advise mothers to bath/shower daily
- Do not wash breasts with bactericidal detergent or soap
- Before expressing milk, it is essential to wash hands thoroughly with soap and water and dry with a disposable towel
- Wipe breast pump with disinfectant wipe before use
- Emphasise to mothers the importance of washing all breast milk collecting equipment properly before sterilising
- Wash equipment with hot, soapy water using bottle brush (not shared), rinse well and dry thoroughly with paper towels promptly after use. Sterilise before use. Discard bottle brushes on discharge
- Give all breastfeeding mothers information available from www.unicef.org.uk/babyfriendly and www.bestbeginnings.org.uk/watch-small-wonders-online
COLLECTION OF BREAST MILK
- Give mother collection kit (sterilise before use) and tamper evident sterile bottles
- Provide parents with patient identification stickers to label milk. Before giving a mother the patient identification stickers, positive identification must be made at the cotside/bedside by 2 people
- Clearly label milk from individual mothers and store in individual patient labelled containers and in a dedicated breast milk fridge (individual containers must not hold bottles from >1 mother)
- Blood and other pigments can discolour milk causing appearance to vary considerably
STORAGE
Where
- Store in designated fridge at 2–4°C. Freshly expressed breast milk can be stored for 48 hr before freezing
- Breast milk can be stored for 3 months -20°C in designated freezer without a defrost cycle (in hospital)
- Freeze breast milk in small volumes with early expression so less milk requires defrosting and potentially less waste when establishing feeds
- Add date and time milk transferred to freezer to label
- Monitor fridge and freezer temperature twice daily using an indwelling maximum/minimum thermometer that is calibrated every 6 months. This temperature should be recorded – date/time, temperature and signature
How
- Place milk in an upright sterile container with airtight lid
- Ensure bottles labelled appropriately – see Record keeping
- Store labelled bottles in separate labelled tray in designated breast milk fridge/freezer (individual containers must not hold bottles from >1 mother)
- Wash trays stored in fridge daily in warm soapy water, rinse well and dry thoroughly
- Clean trays between each use
- Gently agitate milk container to mix milk before use
- refrigerated milk separates with fat globules forming top layer
DEFROSTING
- Use frozen milk in sequence of storage until enteral feeds established
- Thaw frozen milk in waterless warmer or in fridge (if warmer not available)
- If frozen milk needs to be thawed quickly (and warmer not available), hold bottle under cold or tepid water. Gently agitate and do not allow water to enter bottle via cap
- Discard any unused thawed milk (stored in fridge at 2−4°C) after 24 hr if defrosted in fridge or 12 hr if accelerated defrost
USE
- Once removed from fridge, fresh or defrosted milk must be used within 2−4 hr (2 hr preferable)
- Fresh milk is preferable to thawed milk
- Change continuous tube feeding (tubing between nasogastric tube and pump) every 4 hr
- To minimise fat loss, position syringe delivering feed in semi-upright position
- Bolus feeds - warm milk before giving using waterless warmer if available (to minimise fat loss)
- Additives to be added to breast milk as close to feed time as possible
- Only warm volume of milk required for feed. Store remainder in designated fridge
- Before giving breast milk, carry out a 2 person check of the label and cross-reference with baby’s identity bracelet to ensure milk is not given to wrong child
TRANSPORTATION OF MILK
Milk is often transported from:
- Mother's home to hospital:
- transport in insulated container that can be easily cleaned
- encourage mother to use coolant block to maintain stable temperature
- Hospital-to-hospital:
- use rigid container for easy cleaning (e.g. cool box) and fill empty space with bubble wrap
- use coolant block to maintain temperature. Transfer to fridge/freezer if frozen as soon as possible on arrival in NNU/ward
- document amount of milk both fresh and frozen, to ensure any milk defrosted in transit is not refrozen on arrival
PRECAUTIONS
- Wash hands thoroughly
- Cover cuts and abrasions and wear gloves when handling breast milk
Covid-19 suspected/positive
-
Wash hand thoroughly
-
Cover cuts and abrasions and wear gloves when handling breast milk
-
Wipe down the outside surface of ALL individual milk containers using universal disinfectant already in place at hospital
-
Set wiped containers in rack or on tray to dry (wet to dry ensures time for viricidal effect) before storing in refrigerator or freezer
-
Store in expressed breast milk fridge, in an individual, named box with lid
-
Use expressed breast milk within 48 hr of expression and place in expressed breast milk freezer if not used within allotted time
RECORD KEEPING
- Label all bottles/syringes with:
- baby’s name, hospital number and date of birth date and time of expression
- If mother is expressing milk at home, provide her with a supply of labels instructing her to add date and time expressed to each bottle
- If freezing MEBM label date and time frozen, and date and time of defrosting
- See Breastfeeding guideline
STORAGE FOLLOWING DISCHARGE
- Ensure parents take home all MEBM in the fridge or freezer. If some MEBM is left on unit and is in date, transfer from fridge to freezer immediately – inform parents to collect as soon as possible
- Give parents all MEBM on discharge and ensure all milk is checked for correct baby details:
- crosscheck labels on bottles with patient ID (second checker ideally mother)
- if parents not present carry out 2 nurse check and document in patient notes
- Discard milk stored in NNU freezer 1 month after discharge or as per local policy
- Discuss with parents the opportunity of donating any unwanted MEBM to local donor milk bank
