Otitis media secondary to ampicillin-resistant Hemophilus influenzae. An update

Randomised study of myringotomy, amoxycillin/clavulanate, or both for acute otitis media in infants

In a prospective study, 105 infants aged 3-12 months with acute otitis media were randomly assigned to one of three treatment groups: amoxycillin/clavulanate ('Augmentin') alone (36 patients), myringotomy plus placebo (35 patients), or augmentin plus myringotomy (34 patients). The last two groups were double-blinded. Bacterial pathogens, mainly Haemophilus influenzae (of which 20% were beta-lactamase producers) and Streptococcus pneumoniae, were isolated from 60% of the ear exudates and all isolates were sensitive to augmentin. Most of the infants improved clinically within 3-6 days irrespective of the treatment protocol. As judged by otoscopy, 60% of the patients receiving augmentin, with or without myringotomy, recovered completely compared with 23% of patients treated with myringotomy plus placebo. Treatment with augmentin was also more effective than myringotomy with regard to persistence of ear infection. In the myringotomy plus augmentin group closure of the incision and resolution of the discharge from the incision site was faster than in the myringotomy plus placebo group. The addition of myringotomy to augmentin did not seem to affect either the persistence of the infection after treatment or the residual middle ear effusion.

Acute otitis media: a common presentation in the emergency department

Acute otitis media is a common pediatric infection that requires appropriate evaluation of the young child to assure that there are no accompanying systemic infections or complications. The examination of the ear must not only assess the appearance of the tympanic membrane, but determine its mobility. Treatment should be initiated with antibiotics and symptomatic relief. Good follow-up must be arranged.
