URI, pharyngitis, sinusitis, otitis media, and otitis externa Flashcards
how do we treat URIs initially?
viral URIs are self-limiting and require no tx other than symptomatic relief
mainstay of pharmacological management for a cold
a decongestant, either systemic or topical
topical decongestants
- Afrin
- Neo-synephrine
how long can topical decongestants be used?
3 days
after that, may cause rebound congestion
oral decongestants
- Pseudoephedrine HCI (Sudafed)
- Phenylephrine (Sudafed PE)
- Cannot be used to make meth
cardiac patients using oral decongestants
need to be monitored carefully d/t increased risk of HTN from the added vasoconstriction
nonpharmacological therapy for URIs
- Increasing fluid intake
- Using nonmedicated cough drops
- Using nasal saline spray or drops to decrease the viscosity of nasal secretions
- Rest
nonpharmacological therapy for URIs in infants
Suction the infant’s nose with a nasal bulb syringe to clear secretions before the infant eats or drinks
- Infants can’t breathe and drink at the same time if their nose is clogged
how to suspect sinusitis is bacterial in nature?
any URI lasting longer than 10 days without any clinical improvement
or with severe s/s
- High fever (greater than or equal to 39C)
- Facial pain
- Purulent nasal discharge that last 3-4 consecutive days
three s//s have high specificity and sensitivity for diagnosing acute sinusitis
Purulent rhinorrhea
Facial pain or pressure
Nasal obstruction
goals of treatments for sinusitis
absence of infection demonstrated by the patient’s freedom from all s/s
first choice of abx for sinusitis
amoxicillin (with or without clavulanate)
guidelines for starting abx therapy for sinusitis
observe pt for 3 days before beginning abx therapy
abxs are started if there is no improvement of s/s or if the patient worsens during the observation period
abx choice for sinusitis if the pt has PCN allergy (for adults)
Doxycycline or a respiratory fluroquinolone (levofloxacin or moxifloxacin)
abx choice for sinusitis if the pt has PCN allergy (for children)
Third generation cephalosporin (cefdinir, cefuroxime, cefpodoxime)
outcome evaluation of abx therapy in sinusitis
s/s should resolve after 7 days of tx
most common cause of pharyngitis
group A streptococcal (GAS)
pharynx assessment in pharyngitis
- Erythematous, with or without exudate
- Petechiae may be present on the soft palate
- Uvula may be red and swollen
- May have strawberry tongue
how to confirm GAS infection
confirmed by rapid antigen testing or culture
goals of tx for pharyngitis
- Eradicate the bacteria from the pharynx and prevent the development of acute rheumatic fever (ARF)
- ARF may be prevented if antimicrobial therapy is started within 9 days of onset of symptoms
first line tx for pharyngitis
beta-lactams (Penicillin V or amoxicillin)
first line drugs for pharyngitis if pt has a nonanaphylactic PCN allergy
first generation cephalosporin
first line tx for pharyngitis if pt has an anaphylactic PCN allergy
clindamycin or azithromycin
outcome evaluation for pharyngitis tx
s/s should start to improve in the first 24 hours of tx
full therapy is required to prevent ARF
