Module 9 Part 2 Otitis Media – Adult Acute Flashcards
Question
Answer
What are the probable organisms causing acute otitis media in adults without tympanic membrane perforations?
The probable organisms are Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Group A Streptococcus, and Staphylococcus aureus.
What is the first-line antibiotic for treating acute otitis media in adults without tympanic membrane perforations?
The first-line antibiotic is Amoxicillin at a dose of 500 mg three times daily (TID).
Which antibiotics are considered second-line choices for acute otitis media in adults, and what are their dosages?
Second-line antibiotics include Amoxicillin/Clavulanate (500 mg TID or 875 mg twice daily), Cefprozil (250-500 mg BID), Cefuroxime (250-500 mg BID), and Trimethoprim/Sulfamethoxazole (TMP/SMX) (12 tablets BID or 1 double-strength tablet BID).
What organisms are associated with chronic tympanic membrane perforation or ventilation tubes, and what is the recommended treatment?
The probable organisms are Staphylococcus aureus, Pseudomonas aeruginosa, and Viridans Streptococcus species. The recommended treatment is Ciprodex otic suspension (4 drops twice daily), and the cost is $30.43 for 7.5 mL.
What should be considered regarding antibiotic resistance and choice in acute otitis media?
Increased resistance to pneumococcal and H. influenzae may make TMP/SMX less desirable. Macrolides like clarithromycin or azithromycin should be reserved for very rare penicillin-allergic patients.
When is the use of Ciprodex otic suspension suggested, and what is its clinical presentation?
Ciprodex otic suspension is suggested for uncomplicated acute otitis media in the presence of a chronic tympanic membrane perforation or ventilation tubes. The clinical presentation is that of a painless discharge.
What are the key components of Ciprodex and their concentrations per mL?
Ciprodex contains 3 mg of ciprofloxacin and 1 mg of dexamethasone per mL.
