Postnatal Baby Flashcards
What is the golden hour?
A unique time for mother and baby
Uninterrupted skin to skin
Calm environment
At least one hour or until after the first feed whichever comes first
Encourages feeding behaviours
Described as giving the best start in life
Benefits of skin to skin for both the mother and baby?
Calms and relaxes
Regulates breathing and heart rate
Stimulates digestion and supports feeding behaviours
Thermoregulation
Skin colonisation of maternal bacteria
Hormonal response in the mother - oxytocin and prolactin
Why will babies do during initial skin to skin contact?
Cry a distinctive cry
Recover from delivery
Start to awaken
Mouthing and sucking movements begin
Small motor movements begins to move towards the breast
Often rest at the breast
Familiarise with the breast
Self latch and begin to feed
Come off the breast and fall asleep
Benefits of delayed cord clamping?
Increases volume of RBC’s transferred from the placenta by up to 30%
increases iron transfer to the baby
Reduces anaemia in the 1st few months
Reduces need for blood transfusion, risk of death and risk of brain bleeds
Small increased risk of jaundice in babies who have delayed cord clamping
What is apgar scoring?
A score of 0-2 in each criteria: appearance - blue all over, blue only at extremities, no blue colouration.
Pulse - no pulse, <100bpm, >100bpm
Grimace - no response to stimulation, grimace or feeble cry when stimulated, sneezing, coughing or pulling away when stimulated.
Activity - no movement, some movement, active movement.
Respiration - no breathing, weak slow or irregular breathing, strong cry
At 1,5, 10 minutes.
What is included in the initial midwife check of the neonate?
Head circumference
Body temperature
Birth weight
Initial examination
1st feed
Skin to skin
Why are neonates predisposed to heat loss?
They have less subcutaneous fat than adults - subcutaneous adipose tissue froms an insulating barrier around the shell of the body and prevents heat loss.
What type of tissue do neonates have?
Brown adipose tissue
Forms from 30wks - 4wks PN
Well vascularised, cells densely packed with mitochondria and generates heat by non shivering thermogenesis
Breaks down blood glucose and fat molecules to creat heat and maintain body temperature.
Why do pre term infants lose heat more rapidly than a term infant?
They have a large surface area to body mass ratio and decreased subcutaneous fat.
Pre term infants at increased risk of trans epidermal water loss through evaporation
How do neonates lose there heat?
Conduction
Convection
Evaporation
Radiation
What is vitamin K and what does it do? Why do we give it?
Vitamin K helps the body to make certain proteins required for blood clotting for example prothrombin
Prothrombin - vitamin K dependent protein involved in blood clotting
It reduces vitamin k deficiency bleeding
In utero transfer of vit k is poor
Little transfer is breast milk
What are the hormones involved in BF?
Prolactin - stimulation - nervous response sent to hypothalamus - stimulates anterior pituitary - secrete prolactin - stimulates lactocytes - causes milk production
Oxytocin - stimulation - nervous response sent to hypothalamus - stimulates posterior pituitary - secretes oxytocin - stimulates contraction of myoepithelial cells - milk ejection/ let down reflex.
How do we assess infant feeding?
Meaningful conversations as per BFI guidelines
Effective positioning and attachment
Signs of effective milk transfer - happy and content after feeds
Comfort of both mother and infant
BFI feeding checklist
Infant behaviour and appearance
What is lactogenesis 1?
Initiation of milk secretion
Mid pregnancy to early PN - included colostrum
progesterone inhibits prolactin, fall post birth.
What is lactogenesis 2?
Onset of copious production
‘Milk comes in’ around 48hrs post birth when prolactin levels have stimulated milk production
What is lactogenesis 3?
Maintenance of established supply
Local autocrine control - production is mantianed on ‘supply and demand’ basis.
7-10 days post birth.
What does early frequent feeding do?
Primes receptor sites to improve and maintain milk production for ongoing feeds.
What are the differences in the gut of a BF baby and AF baby?
Different types of bacteria are found in gut of breastfed to artificial fed babies - different gut flora and less pathogenic bacteria.
PH level is more acidic in BF babies which is preferred
The neonatal gut is immature and immunonaive
What are the benefits of colostrum?
Antibodies and immunoglobulins are proteins
Vitamin K and E are fat soluble - lower fats = energy
Secretory IgA levels - protect the gut lining against pathogenic bacteria
anti - infective properties - macrophages, lymphocytes, lactogerrin, lysosomes etc.
What does BF reduce the risk of?
Gastroenteritis
Respiratory Illness
Ear infection
UTI
Allergies
Necrotising enterocolitis
What do growth factors in breastmilk do?
Helps mature the gut.
What does the NIPE consist of?
Eyes
Heart
Hips
Testes
Within 72 hours of birth
Again at 6-8 wks
What are the key elements of safe sleeping?
On their back
Seperate cot or Moses basket in same room for at least 6 months
Keep baby in a smoke free environment
Use a firm flat waterproof mattress
breastfeed baby
What increases the risk of SIDS?
Sleeping on the sofa increases it by 50X
Young babies may be at risk of breathing difficulties if they travel while sitting in an upright position for too long.
Low birth weight (under 2.5kg and prem babies) at an increased risk of SIDS
