An alternative simple method in laryngoscope blade decontamination

The cleaning and disinfection of laryngoscope blades is controversial. The aim of this study is to investigate the efficacy of two different chemical disinfectant agents and tap water where the laryngoscope blades were contaminated by different microorganisms and try to create a simple, effective and easy decontamination method. The results of our study demonstrate that the decontamination of the laryngoscope blades, which are cleansed with tap water, is not a reliable approach. In conclusion, mechanical cleaning of blades with water and the immersion in 2% glutaraldehyde or 10% polyvinyl pyrrolidine iodine for 10 minutes is an effective method for decontamination of laryngoscope blades.
