1 Airway Mgmt Flashcards
Inter incisor gap: shows what, small means what, nml cm
Ability to align axis, more acute angle b/w oral and glottic. 4
TMD: cm difficulty
<6 or >9 cm.
Mandibular protrusion, which classes good or not
I good, III bad
Normal AO flexion
90-165 degrees
Normal AO extension, difficult when
35 degrees. <23 degrees
Conditions that impair AO mobility
Klippel feil, downs
Grade IIa v IIb view
A= only posterior glottic opening. B= only corniculates and posterior VC, no opening view
RF for difficult mask
BONES BMI >26 age >55
RSI cricoid p before and after LOC
2kg/20 newtons before, 4/40 after
Causes of angioedema and tx of each
ACEI: epi, antihistamines, steroids. C1 esterase deficiency: FFP or C1 esterase, epi/antihistamine wont work
Ludwig’s angina: what it is, best way to do airway or not to do it
Infec roof of mouth. Do awake nasal or trach. Dont do retrograde in infec above trachea
Syndromes w large tongue
BT big tongue; beckwith, trisomy 21
Small mandible syndromes
Please get that chin: Pierre robin, goldenhaur, treacher Collins, cri du chat
Cervical anomaly syndromes: kids try gold
Klippel fail, trisomy 21, goldenhaur
Pierre robin dev from nml how
Small mandible (micrognathia/hypoplasia), tongue falls back (glossoptosis), cleft palate
Treacher Collins deviations
Small mouth and mandible, nasal a/w blockage (Chantal atresia)
Trisomy 21 deviations
Small mouth large tongue AO instab, small subglottic diam (subglottic stenosis)
Klippel feil dev
Neck rigidity
Cri du chat abn
Small mandible, laryngomalacia, stridor
ETT goes where what goes
Nose. Nose to chest= tip to carina, nose away- tip away
Contraindic to nasal airway
Lefort II or III, basilar frac, prev transphenoidal hypophysectomy or Caldwell luc procedure
Why low vol high p cuffs good vs bad
Good: better aspiration risk. Bad: tracheal ischemia and cant measure pressure
What most ett cuffs are
Low pressure high vol
LMA cuff: max PPV pressure, max cuff pressure
PPV 20 cm h20, cuff 40-60 target range
