Acute otitis media passmed Flashcards
How common is Acute Otitis Media in young children?
Acute otitis media is extremely common in young children, with around half having three or more episodes by the age of 3 years.
Describe the pathophysiology of Acute Otitis Media.
Acute otitis media typically follows viral upper respiratory tract infections, which disturb the nasopharyngeal microbiome. This enables bacteria like Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis to infect the middle ear via the Eustachian tube.
What are the clinical features of Acute Otitis Media?
Features include otalgia, ear tugging or rubbing by some children, fever in about 50% of cases, hearing loss, and possible ear discharge if the tympanic membrane perforates. Recent viral URTI symptoms are common.
What criteria are commonly used to diagnose Acute Otitis Media?
Diagnosis criteria include acute onset of symptoms, otalgia or ear tugging, presence of a middle ear effusion, bulging of the tympanic membrane, otorrhoea, decreased mobility on pneumatic otoscopy, and inflammation of the tympanic membrane.
How is Acute Otitis Media managed?
Acute otitis media is generally self-limiting and may not require antibiotics unless symptoms persist, the child is systemically unwell, immunocompromised, or at high risk of complications, or under 2 years old with bilateral conditions. Amoxicillin or, in case of allergy, erythromycin or clarithromycin is prescribed.
What are the common sequelae and complications of Acute Otitis Media?
Common sequelae include tympanic membrane perforation leading to otorrhoea and potentially chronic suppurative otitis media if unresolved over 6 weeks. Complications can include mastoiditis, meningitis, brain abscess, and facial nerve paralysis.
When should a patient with acute otitis media be admitted to the hospital?
If they have:
Severe systemic infection
Complications (e.g., meningitis, mastoiditis, facial nerve palsy)
Are under 3 months old with a temperature > 38 degrees
What is the usual course duration for acute otitis media?
About 3 days but can last up to 1 week.
What medications are recommended for pain management in acute otitis media?
Regular doses of paracetamol or ibuprofen.
Are decongestants or antihistamines effective in managing acute otitis media?
No, there is no evidence to support their use.
What should be advised if no antibiotic prescription is given for acute otitis media?
Most cases will resolve spontaneously. Advise to seek help if symptoms haven’t improved after 3 days or if the child deteriorates clinically.
What is a back-up antibiotic prescription for acute otitis media?
Advise that the antibiotic is not needed immediately but should be used if symptoms have not improved after 3 days or if they have worsened significantly at any time.
What is an immediate antibiotic prescription for acute otitis media?
Seek medical help if symptoms worsen rapidly or the patient becomes systemically unwell. First-line antibiotic is Amoxicillin for 5-7 days.
What antibiotics are recommended for patients with a penicillin allergy?
Clarithromycin or erythromycin.
What is the effect of antibiotics on acute otitis media?
Antibiotics marginally reduce the duration of the pain but have no effect on the risk of hearing loss.
