title: Infection control practices of laryngoscope blades: a review of the literature.
abstract: Current procedures for cleaning anesthesia airway equipment as assessed by the presence of visible and occult blood on laryngoscope blades and handles as labeled "ready for patient use" has been reported to be ineffective. Human immunodeficiency virus (HIV) and the hepatitis B virus (HBV) are 2 commonly seen pathogens that frequently are found in the healthcare setting. It has been shown that HBV can survive on a dry surface for at least 7 days and both HIV and HBV are transmitted via blood. The potential for cross-contamination from airway equipment to patient has been shown in several studies. To prevent further potential infections, it should be ascertained why anesthesia providers are not all using disposable laryngoscope blades. The purpose of this literature review is to determine the use and infection control practices of disposable laryngoscope blades. Their frequency of use, their evaluation of ease of use, and any complications encountered when using the disposable blade are reviewed, as well as the perceptions of anesthesia providers regarding disposable laryngoscope blades.
