Right - Guess Flashcards
What type of meds avoid in DBS surgery for Parkinson’s? (Need to wake them up)
Gaba agonists (use precedex and alpha 2 agonist)
treatment for extravasation of vasopressor
phentolamine into area
In ambulatory surgery what can you do to reduce nausea (3 things) and does neostigmine dose reduction help prevent nausea?
Avoid N20
adequate hydration
propofol
nope!
inheritance pattern of MH
autosomal dominant with variable penetrance
TPN can lead to cholestasis T/F
T
efferent nerve responsible for laryngospasm
recurrent laryngeal
afferent nerve responsible for laryngospasm
internal branch of superior laryngeal
(sensory of the trachea at and above the level of vocal cords)
*external innervates the cricothyroid muscle.
ETT intubation is contraindicated in setting of laryngeal ***** disruption or laryngotracheal separation?
cartilage
go to the knife
pathologies that are CI to retrograde intubation?
anything obscuring landmarks (thyroid goiter)
how treat in prevent inhalational anthrax?
cipro or doxy, untreated has mortality rate of 80-100%

in an open thoracotomy where lung isolation is critical, what time of device do you want? DLT vs bronchial blocker?
DLT, more reliable
When would you want a bronchial blocker ofer DLT?
- selective lobar collapse
- challenging airways
- tracheostomy
- children <12y/o
- when post-op ventilation anticipated (can leave a DLT in if going for surgery in next day or so)
higher blood:gas partition coefficient = higher/lower solubility
higher
