Q

HOW TO: irrigation

A
  • use warm water

Q

Otitis externa management

A

Abx ear drops 7-10 days, 5+ drops 3-4 times a day

decreased hearing
Fever
erythema, retraction/bulging “DONUT” decreased mobility of TM, occasional bullae

25
Q

acute otitis media 2nd conditions

A

acute mastoiditis - cefazolin and myringotomy for culture & drainage

A

tylenol and ibuprofen (no I <6 months)
antibiotics indicated for <6 months, bilateral AOM, or with strong atalgia, >48 hours, >39/102.2
amoxicillin
amoxicillin-clavulanate (if recieved a in last 30 days, unresponsive)

A

viral illness – systemic & intranasal decongestants w autoinsufflation

result of sudden pressure change, sudden dysfunction
can clear w popping or time, or causes bleeding or fluid leakage, worst = fistula

OTC decongestants (pseudoephedrine)
topic decongestants - phenylephrine or oxymetazoline

keep kids upright, bottle/pacifier, special ear plugs

48
Q

TMP symptoms

A

ear pain, otorrhea, hearing loss, whistling sound

Q

hemotympanum

A

bloody otorrhea present only if TM ruptures, otherwise behind TM. consider ENT removal, vascular tumor?

50
Q

A

due to trauma, stables –>vestibule

A

barotruama, rapid descent, explosion, straining

52
Q

A

oral corticosteroids, stool softeners to reduce straining, tympanotomy to enhance healing
