What is the efficacy of sterile sheath use to prevent cross-contamination when using a fiberoptic nasopharyngolaryngoscope (FNPL) in an otolaryngology clinic?
Explore this issue:December 2010
Background: After each use of FNPL, the endoscope must be disinfected before it is used in another patient to prevent cross-contamination. Previous reports suggest that methods for disinfection vary among facilities, and medical assistants who disinfect the devices do not necessarily adhere to standard methods. Additionally, the use of liquid germicidal agents does not prevent contamination with bacterial spores. An individually packaged disposable sterile sheath (IPDSS) has been designed to fit over the FNPL and has been marketed as a means of preventing cross-contamination
Study design: Prospective controlled trial
