25
what to avoid with foreign body?
Positive pressure!
26
most common nerve problem
unilateral facial paresis
27
nerve preservation methods
avoid muscle relaxers or use short acting, avoid locals and N2O
28
Nerve stimulators common in middle ear procedures meaning:
no muscle relaxers after intubation
29
N2O implications with middle ear procedures?
Avoid N2O or turn off >15 min before closing (moves into middle ear = displacement of graft) -N2O also increases risk of PONV
30
Myringotomy (tubes) implications
no IV N2O ok nasal fent and dext used
31
Most common pediatric surgery
Tonsillectomy & Adenoidectomy
32
implications of NSAIDS with T&A?
ENTs want to avoid d/t increased risk of bleeding. Studies show NSAIDs = no difference in bleeding, less PONV
33
anesthesia implications for T&A
Airway obstruction, shared airway, suspension, rapid awakening, pain mgt, PONV
34
Bleeding Tonsil can present
hypovolemic, tachycardic, hypotensive give crystalloid bolus pre-op
35
all bleeding tonsils are
full stomachs
36
induction for bleeding tonsils?
rapid sequence induction
37
anesthesia implications bleeding tonsils?
rapid sequence Suction stomach before emergence Extubate FULLY awake!!
38
thyroid procedure implications
myesthenia gravis meds taken am steroid stress dose
39
Inadvertent resection symtpoms
unilateral or bilateral VC paralysis = airway emergency after extubation
40
motor innervation to vocal cords?
recurrent laryngeal and external branch of superior laryngeal
41
type of MR used for thyroid procedures
sux or short acting
42
gold standard for thyroid procedures?
Intra-op nerve monitoring ETT with 4 embedded electrodes Red = R, Blue = L (“NIM” tube)
43
thyroid storm signs?
Increasing core temp and/or hyperdynamics
44
caution in thyroid procedure?
Hypocalcemia 24-96 hrs post-op d/t damaged parathyroid glands (Numb/tingling -laryngospasm- seizures-dysrhythmia-CV arrest
45
huge anesthesia implication thyroid surgery?
post op hematoma!! ER a/w obstruction
46
anesthesia implications cleft lip/palat
difficult mask/intubate fluid moving around a/w and obstructing elbow restraints
47
damage to horizontal, nose/palate, septum, and posterior pterygoids
Le fort fracture I
48
triangular nose, orbit, below zygoma, lateral maxilla and pterygois
le fort frature II
49
complete separation of midface from the cranial base across nose, ethmoid, orbit, sphenopalantine fossa
le fort III
50
When can you not use nasal ETT w/o fiberoptic guidance for le fort fracture
if basilar skull fracture suspected (csf/blood/raccoon)
51
anesthesia implications facial fractures
full stomachs nasal ETT extubate awake PONV
52
important post op facial fractures?
wire cutters at bedside
53
history of radiation leads to
difficult a/w related to tissue changes, TMJ, etc.
54
head up position and open neck veins could result in
VAE
55
Most common & effective for profound analgesia/akinesia of eye and lids
ocular LA (retrobulbar or peribulbar)
56
what cranial nerves have to be blocked ophthalmic surgery?
III, IV, V, VI, VII
57
For full stomach, open-eye pt, s this an easy airway and eye viable?
If yes, use rocuronium.
58
For full stomach, open-eye pt, s the eye viable?
If yes, but airway could be difficult, use Sux because a/w trumps eyeball
59
oculocardiac reflex afferent and efferent?
afferent trigeminal (V), efferent vagal (x)
60
OCULOCARDIAC REFLEX
Sudden, profound bradycardia (can cause other dysrhythmias)
61
OCULOCARDIAC REFLEX txt
Stop the stimulus -If unresolved, atropine or glycopyrrolate - “Fatigues” with continued manipulation
62
Max sub-cu lidocaine
35 mg/kg
63
max sub cu epi
70 mcg/kg
64
major cause of mortality in liposuction
VTE
65
highest incidence of death from VTE?
abdominoplasty, especially combo lipo
66
ways to decrease risk of fires?
Minimize FiO2, avoid flammable preps, avoid O2 accumulation under drapes, communicate with surgeon (cautery)
