Pediatrics, ENT, & MH Flashcards
How long should you wait for elective procedure if patient has recently had a URI?
4-6 weeks (otherwise, higher risk of increased airway reactivity)
LMA or ETT in children with URIs?
LMA (ETT has higher risk of bronchospasm)
True or false: incidence of airway complications with children with active vs. recovery period of URI are almost identical?
True
Formula for calculating ETT size in children
4 + (Age/4)
Formula for estimating correct depth of ETT in children
12 + (Age/2) or weight in kg/5 + 12 or 3x diameter of ETT
What nerve stimulation causes laryngospasms?
Superior laryngeal nerve
Treatment for kid with high pitched inspiratory noises in PACU
Post-intubation croup: racemic epinephrine nebulization
Steeple sign on X-ray
Croup
Thumb sign on X-ray
Epiglottitis
Treatment of croup
Racemic epinephrine, steroids for long-term
Best ETT for laryngeal polyp excision using a CO2 laser?
Metal ETT or intermittent intubation and ventilation
What to do when you notice smoke from ETT during CO2 laser?
Extubate the trachea, flood the field with saline, then examine with fiberoptic
Scoliosis is associated with which of the following: seizure disorder, mental retardation, hirsutism, MV stenosis, pulmonary HTN
Pulmonary HTN (restrictive lung disease from rotated, constricted thorax)
Why do wake-up tests and MEPs together?
MEPs are prone to false positives, but are continuous monitors; wake-up tests are definitive but non-continuous
Risks of a wake-up test during spine surgery?
Unintentional extubation, dislodgement of lines and instruments, air embolism (inspiration drawing in air through vertebral veins)
4 year old with OSA, which is likely associated with this condition? Peritonsillar abscess, cor pulmonale, choanal atresia, subglottic hemangioma, laryngomalacia
Cor pulmonale (cardiorespiratory syndrome): right heart failure
Major concerns for peritonsillar abscesses?
Obstruction of glottic opening; rupture of abscess; therefore, spontaneous breathing is important on induction
