Recommendations to Resolve Inconsistent Guidelines for the Reprocessing of Sheathed and Unsheathed Rigid Laryngoscopes

Neither a consensus statement nor a formal set of step-by-step guidelines for reprocessing rigid laryngoscopes have been published or endorsed by professional organizations. Several published guidelines, standards, and clinical reports were reviewed to evaluate the risk of nosocomial infection associated with the use of rigid laryngoscopes, to determine their minimum reprocessing requirements. This review found that the recommendations of some guidelines and standards for reprocessing rigid laryngoscopes are incomplete, inadequate, and inconsistent with one another, and that current practices for reprocessing rigid laryngoscopes are reported to be inadequate and lack standardization. It is recommended that a consensus statement be developed that standardizes the reprocessing of rigid laryngoscopes and requires cleaning followed by high-level disinfection (or sterilization) and drying of the rigid laryngoscope's blade and handle to prevent nosocomial infection, regardless of whether a protective barrier or sheath is used during the procedure.
