27
95% of cases of trisomy 21 are due to _______________
nondisjunction of chromosome 21
28
what risk factor is associated with trisomy 21
increased maternal age
29
screening methods for trisomy 21

30
the average life expectancy of someone with trisomy 21 is ____________ years of age most commonly due to ________________
35; cardiac issues
31

32
anesthetic considerations for pt with Trisomy 21
1. may be difficult intubation (d/t atlantoaxial instability) 2. cardiac dz 3. less muscle relaxant required 4. increased risk of post-intubation stridor (due to tracheal/subglottic stenosis) 5. pretreatment atropine due to large risk of brady cardia 6. difficult bag (big tongue)

38
if bby is having issues breathing right after birth they will most likely be worked up for ___________________

44
anesthesia implications for DiGeorge
1. strict aseptic technique/use of irradiated blood due to immunosuppression 2. cardiac defects 3. possible difficult airway due to retrognathia and/or micrognathia
