Newborn Screening Flashcards
When should routine examination of newborn infant take place
Within 72 hours
Key components of routine examination
Red reflex Undescended testes DDH - Barlow and Ortolani maneovre Vitamin K injection Newborn hearing Oxygen saturation screening Biochemical screening - Guthrie test
Order of routine examination
Auscultation Feet (unclothed) Femoral pulse Genitals - undescended testes, hypospadidas Anus + sacrum Abdominal palpation Chest inspection Back + head shape (sat up) Hands - palmar creases (clothed) Red reflex Mouth - inspection, sucking reflex, palpation beyond hard palate Nose Fontanelle Moro Reflex
How do you check for DDH
Barlow maneovre - to see if dislocatable, stabilise other hip, flex at hip, push down and adduct femoral head
Ortolani maneovre - to revert back into acetabulum, abduct and raise femoral head, hear ‘clunk’
How to screen for congenital heart disease
To detect duct dependent CHD
Oxygen saturation
- low post ductal saturation
- right hand (pre-ductal) compared to post ductal
What does biochemical screening test for
CF
Congenital hypothyroidism
Haemoglobinopathies - sickle cell, thalassaemia
6 inborn errors of metabolism - phenylketonuria, homocystinuria, MCAD, maple syrup urine disease, isovaleric acidaemia, glutamic aciduria type 1
When and how to perform biochemical screening
On day 5-7 (feeding established)
