Abstract
OBJECTIVE: To determine if the use of ear protection when swimming of children with ventilation tubes modifies the risk of acute otitis media (AOM) compared to not swimming. METHODS: Systematic review. DATA SOURCES: Search conducted in MEDLINE, EMBASE and The Cochrane Library databases. STUDY SELECTION: Prospective cohort studies and controlled clinical trials of children with ventilation tubes, with a minimum follow-up of 2 months. DATA EXTRACTION: Two reviewers independently assessed trial quality and extracted data. RESULTS: 11 studies were selected. No difference was found in risk of AOM in children who swim without ear protection compared with those who do not swim: Odds ratio=0.78, 95% confidence interval 0.42-1.44; nor compared with those who use earplugs and swimming caps, odds ratio=0.75, 95% confidence interval 0.38-1.48; nor in those who use ear drops after swimming compared with those who used earplugs or swimming caps, odds ratio=0.76, 95% confidence interval 0.56 to 1.02. The use of ear drops after swimming increases the risk of AOM in children with ventilation tubes as compared with those who do not swim, odds ratio=3.14, 95% confidence interval 1.40 to 7.05. CONCLUSIONS: There is no evidence to suggest that protection when swimming with earplugs, swimming caps or ear drops in children with ventilation tubes reduces the risk of AOM. Ear drops may even increase this risk.
