Peds Medical Conditions Flashcards
What is the most frequent chromosomal aberration?
Down Syndrome @ 1.5 per 1000 live births
Major airway characteristics associated w/down syndrome
short neck, macroglossia, mandibular hypoplasia narrow nasopharynx hypertrophic T&A subglottic stenosis c-spine instability
major CV problems w/down’s
CV d/o 40 - 50 % (ASD, VSD, TOF, PDA, AV Canal Defect)
down’s & AAI
characterized by excessive movement at the junction between the atlas (C1) and axis (C2) as a result of either a bony or ligamentous abnormality. Neurologic symptoms can occur when the spinal cord or adjacent nerve roots are involved.
7 - 36%
AOI
Atlanto-occipital dislocation involves complete disruption of all ligamentous relationships between the occiput and the atlas. Death usually occurs immediately
airway considerations for ds
assess OSA
downsize ETT
video blad
cardiac considerations for ds
bradycarda on induction
CHD? bacteria endocarditis prophylaxis
pulm. HTN d/t CHD or OSA
ds & hypothyroidism
delayed GI, altered drug metabolism
MPS
genetic lysosomal storage disease that has malfunctioning enzymes. they normally break down glycosaminoglycans or ‘gags’
MPS or GAGs are long chain CHO found in the cells of bone, skin, CT, corneas
MPS s/s
striking skeletal features
behavior
MPS I
hurler
tx: stem cell, ERT, supportive
enzyme: alpha-L-iduronidase
MPS II
hunter
tx: ERT, supportive
enzyme: iduronate sulfatase
hurler syndrome
genetic (autosomal recessive)
glycosaminoglycan buildup
dead by 10 d/t organ damage
hurler s/s (5)
hepatosplenomegaly dwarf + unique facial features broad chest, spine deformities recurrent respiratory infections CAD, mitral valve thickening, CM
worst airway in peds (8)
hurler b/c
- big head
- large tongue, lips, T&A
- snotty
- narrow trachea
- OSA
- short neck
- high epiglottis
- atlantoaxial subluxation
WORSE WITH AGE
