Corrosion of a silver Negus tracheostomy tube
Published online by Cambridge University Press: 29 June 2007
Abstract
Corrosion of silver tracheostomy tubes has previously been reported. In all of these reports, it occurred at the junction between the neck plate and the outer tube where an alloy of inferior corrosion resistance, compared to silver, has been used in the brazed joint. We present, to our knowledge, a previously unreported case of corrosion of the main body of the outer tube of a silver Negus tracheostomy tube where no such alloy is present.
