HEENT Part III Flashcards
anterior and posterior chambers of the eye make up the ___________; which has a volume of about __________mL
globe; 7
which eye muscle causes supraduction (rolling) of the eyes
superior rectus
which muscle is responsible for infraduction of the eye
inferior rectus
which muscle is responsible for adduction of the eye
medial rectus
which muscle is responsible for abduction of the eye
lateral rectus
which muscle is responsible for intorsion/depression of the eye
superior oblique
which muscle is responsible for extorsion/elevation of the eye
inferior oblique
emergence consideration with opthlamic surgery
- no coughing or bucking 2. avoid hypercapnea 3. prevent PONV 4. remifentanil (prevents coughing with emergence)
when would you typically use GETA with opthlamic surgery
- peds 2. uncooperative pts 3. emergenceis
what is a primary clinical sign of increased IOP
nausea
t/f: stable facial fractures are not considered emergent
TRUE
anesthetic considerations with pharyngeal abscess
- careful with intubation 2. consider awake intubation
with thyroidectomy 2/2 hyperthyroidism, _________________ meds should be avoided
anticholinergics (except for reversing NMB)
during a thyroidectomy, if the pt becomes hypotensive, how should you tx?
with a direct acting vasoconstrictor (neo)
with thyroidectomy, what anesthetic drugs should be avoided
local anesthetics and paralytics
complications of thyroiectomy surgery
- RLN injury 2. neck hematoma –> tracheal deviation 3. infection 4. tracheomalasia 5. hypocalcemia
if you expect a neck hematoma post-thyroidectomy d/t tracheal deviation (causing compression of trachea) what should you do
call surgeon immediately, but if cannot wait cut the sutures to relieve the pressure
unilateral RLN injury sx
hoarsness
bilateral RLN injury sx
stridor d/t unopposed adduction –> emergent intubation
why is N2O avoided during ear surgery?
- N2O is 34x more soluble than nitrogen in blood –> increased middle ear pressure 2. cannot relieve the pressure via yawning or swallowing d/t anesthetic
N2O should be avoided with all ear surgeries, except __________________
