Infection control practices of laryngoscope blades: a review of the literature

Area of Science:

• Anesthesiology
• Infection Control
• Medical Device Safety

Background:

• Current cleaning methods for anesthesia airway equipment are ineffective, with blood often present on reusable laryngoscope blades.
• Human immunodeficiency virus (HIV) and hepatitis B virus (HBV) are bloodborne pathogens posing a significant risk in healthcare settings.
• Hepatitis B virus (HBV) can survive on dry surfaces for over 7 days, increasing cross-contamination risks from airway equipment.

Purpose of the Study:

• To determine the utilization and infection control practices associated with disposable laryngoscope blades.
• To review the frequency of use, ease of use, and any complications related to disposable laryngoscope blades.
• To understand anesthesia providers' perceptions regarding the use of disposable laryngoscope blades.

Main Methods:

• Literature review of studies on disposable laryngoscope blade usage.
• Analysis of infection control protocols and their effectiveness.
• Examination of anesthesia provider feedback and experiences.

Main Results:

• Disposable laryngoscope blades offer a potential solution to reduce cross-contamination risks.
• Studies indicate a need to understand barriers to the adoption of disposable blades.
• Anesthesia provider perceptions on usability and complications are crucial for implementation.

Conclusions:

• Widespread adoption of disposable laryngoscope blades is recommended to enhance patient safety.
• Further research is needed to address anesthesia providers' concerns and optimize the use of disposable blades.
• Implementing disposable laryngoscopes is a key strategy to prevent healthcare-associated infections.
