Inadequate reprocessing of rigid laryngoscopes has been linked to nosocomial outbreaks with associated morbidity and mortality. Last year an outbreak of Pseudomonas aeruginosa in a neonatal intensive care unit was responsible for multiple infections and colonisations, and at least two infant deaths. An investigation of this outbreak identified contaminated rigid laryngoscopes as its source, demonstrating that inadequate reprocessing of rigid laryngoscopes remains a current public health concern. ⋯ Concern about guidelines that recommend low-level or intermediate-level disinfection of rigid laryngoscopes is expressed. The use of a sterile disposable sheath to cover the rigid laryngoscope and minimise the risk of contamination is also discussed. Regardless of whether a sheath is used during the procedure, thorough cleaning followed by high-level disinfection and drying of the instrument is recommended to prevent microbial transmission.
