Upper Respiratory Tract Infection Flashcards
What are possible upper respiratory tract infection (URI) that have been discussed?
- Otitis Media
- Sinusitis
- Pharyngitis
- Laryngitis
- Common cold
What is Otitis Media?
Inflammation of the middle ear
What is considerd acute otitis media (AOM)?
Rapid symptomatic infection with fluid in the middle ear
What is considered otitis media with effusion (OME)?
No signs of acute illness but fluid in middle ear
Why is daycare considered a risk factor for AOM?
More likely to be exposed to resistant bacteria (also seen with recent antibiotic use)
What are common bacteria that may cause AOM?
- Streptococcus pneumonia
- Hemaophilis influenza
- Moraxella catarrhalis
What is the pathophysiology associated with AOM?
Nasopharyngeal viral infections impair eustachian tube function causing the mucosa mucociliary clearance promoting bacterial infection (children less able to drain tube compared to adults) with possible effusion from allergens/toxic exposure
What are the requirements for a diagnosis of AOM?
- Rapid onset of S/Sx
- Middle ear effusion finding with pneumatic otoscopy
- Inflammation indicated by either otoscopic evidence or otalgia
How is a severe AOM different from a non-severe AOM?
- Pain (mild vs moderate/severe)
- Fever (above vs below 39ºC, past 24h)
What treatment goal for patients with AOM?
Focus on symptom relief (i.e. pain, relief) and prevention of complications; Ususally resolves spontaneously with no treat
What are non-pharmacological therapies are available for treatment of AOM?
- External heat/cold (pain relief)
- Tympanostomy tubes (chronic OME)
- Adeniodectomy (Chronic nasal obstruction)
What is common ABX resistance observed in patients with AOM? (think common bacteria)
Penicillin-resistant Sreptococcus pneumoniae (PRSP)
When should ABX be used for AOM? (Think age dependent)
- < 6 months: Use ABX
- 6 M/O – 2 Y/O w/ certain DX: use ABX
- > 2 Y/O w/ certain DX and severe infection: use ABX Otherwise observe and treat if needed
T or F: When patients with AOM should consider penicillin allergies?
T
If patient has no allergy and no severe illness, what ABX should be considered for treatment?
-
Aminopenicillins
- Amoxicillin (high dose)
-
3rd Generation Cephalosporins
- Cefuroxime
- Cefpodoxime
- Cefdinir
If a patient has no allergies but severe illness, what ABX should be considered for treatment?
- Augmentin (Amoxicillin + Cavulanic Acid)
- Ceftriaxone (IV/IM)
If patient has a Type 1 allergy to penicillin, what ABX should be considered for treatment?
- Macrolides (Erythromycin)
- Clindamycin
- Trimethoprim/sulfamethoxazole
If a patient has a non-type-1 allergy, what ABX should be considered for treatment?
Non-severe:
- Cefuroxime
- Cefpodoxime
- Cefdinir
Severe:
- Ceftriaxone (IM/IV)
What analgesics are available for patients with AOM?
If fever:
- Acetaminophen
- Ibuprofen
If no fever:
- Benzocaine (topical; Auralgan drops)
