Q

How is AOM Tx’d?

A

<6wks:
- Ix bacteremia, go to ED

6wk-6mo:

  • analgesics
  • Amox x10 days

> 6mo

w/ RFs:
Immediate Tx for:
- child w/ high fever (>39)
- mod-sev systemically ill
or - very severe otalgia
or - significantly ill >48 hrs
low RFs:
- watchful waiting + analgesics 
OR give Abx Rx to parents to use if child doesn't improve w/in 48hrs 
Drug: Amoxicillin 
<2y/o - x10 days
>2 y/o - x5 days
- if/ Tx fail = 
Amox-clav
cefprozil, 
Ceftriaxone im/iv × 3 days

Q

How do you treat otitis externa?

A

TX = NONE, self resolving…
(analgesics)
summary: if doesn’t and prs looks toxic –> abx/steroid drops

Bacterial:

  • neo/poly/HC only if TM intact, - FQ ex. cipro (use a wick if canal is swollen),
  • systemic therapy if canal is swollen shut or pt is immunocompromised/DM
  • Fungal: acetic acid/HC drops, clotrimazole drops
  • Bacterial vs fungal? CASH (drying) powder covers both
  • Chronic treat eczema with steroid cream, then use vinegar/water washes and avoid Q-tips
  • Malignant emergent referral to ENT
