What is the association between breasting feeding and HDNB?
Late disease more commonly seen in breast fed babies
When should pulse oximetry screening be done and why? Who should be screened?
Should be done between 24-36 hours and not before because of rate of false positives being higher
- All term and late preterm infants
When should prophylactic antibiotics be given to an infant?
All infants born <33 weeks born to mothers with chorioamnionitis or PPROm should recieve abx for 36-48 hours until culture were negative
When should prophylactic antibiotics be given to a mother?
PPROM and expecting to delivered before 33 weeks
Consider it in GBS unknown mothers with preterm delivery

If <34 weeks GA
When should baby be put in a bag to prevent hypothermia?
If <32 weeks
What are targets for PCO2 when ventilating a neonate? Why?
Target between 45-55 with a max of 60
To help prevent periventricular leukomalacia (PCO2 below 35 mmHg) and intraventricular hemorrhage (PCO2 above 60 mmHg
What are indications to start iNO?
GA>35 weeks OI >20-25 PaO2<100 when on 100% FiO2 ECHO has rule out congenital heart disease Conventional therapies are failing
