2022 Flashcards
What adverse outcomes are PDAs associated with in preterm infants?
- prolonged assisted ventilation
- pulmonary hemorrhage
- CLD
- NEC
- IVH
- death
What prophylactic COX-1 drug can be used in ELBW/extreme prem infants to close the PDA?
Indomethacin IV
Note: there is insufficient evidence for ibuprofen or acetaminophen prophylaxis in this age/wt group.
What investigation should be done to confirm the presence of a PDA?
Echo
List examples of conservative management of a PDA.
- diuretics
- increase PEEP
What medication is preferred for the management of symptomatic PDAs in infants >26 weeks?
Ibuprofen
Note: can do high dose if the baby is >3-5 days old (Day 1: 15-20 mg/kg, Day 2-3: 7.5-10 mg/kg)
When should you consider procedural PDA closure (cath or surgery)?
If the infant has a persistent and symptomatic PDA with echo findings of a large shunt and pulmonary overcirculation after having 2 rounds of pharmacotherapy (or less if pharmacotherapy was contraindicated).
Should you refer an infant to cardiology if they have a persistent PDA at discharge?
Yes
By what age does infantile GER typically resolve?
1 yo
List the recommended non-pharmacological strategies to address infantile GERD.
- Thickened feeds
- Avoiding cow’s milk protein - should only be trialled if 2 weeks of thickened feeds failed to show symptom improvement.
Is infant re-positioning recommended as a non-pharmacological management of GERD?
No.
There is weak evidence to support any improvement in GERD symptoms. In addition, there is strong evidence that flat, back to sleep prevents SIDS in infants.
For what clinical symptoms is acid-suppression recommended as treatment for GERD?
Symptoms of Erosive Esophagitis
1. Hematemesis
2. Failure to feed
3. Failure to Thrive
Are prokinetics recommended in the management of infantile GERD?
No.
Limited evidence and significant negative side effects.
List 5 general risk factors for reduced bone mass.
- chronic inflammation
- reduced physical activity or low muscle mass
- pubertal delay
- poor nutritional status (either from inadequate intake or absorption)
- certain medications
- Obesity
Define pediatric osteoporosis
≥1 vertebral fracture in the absence of local disease or high-energy trauma
OR
≥2 long bone fractures by 10 yo OR ≥3 long bone fractures at any age until 19yo WITH a reduced BMD Z-score ≤2.0
What details will you ask a patient when obtaining an osteoporosis-specific history?
- personal and family fracture history
- back pain
- diet (Ca sources)
- physical activity
- sun exposure, sunscreen use
- onset of puberty
List examples of osteotoxic medications
- steroids
- traditional AEDs (phenytoin, PHB, carbamazepine, valproate)
- GnRH agonists
- medroxyprogesterone
- calcineurin inhibitors
- antiretrovirals
- anticoagulants
- loop diuretics
- high dose methotrexate
