Disinfection and Sterilization in the Otolaryngologic Outpatient Clinic

For the disinfection and sterilization of otolaryngologic instruments in outpatient clinics, two processes exist. One process is used for heat-resistant instruments: cleaning→physical disinfection→drying→ (autoclave sterilization), while the other process is used for non heat-resistant instruments: cleaning→chemical disinfection→rinsing→drying. In both processes, cleaning is especially important. For metallic instruments, disinfection by boiling or hot water disinfection combined with autoclaving for sterilization provides safe and economical disinfection. Instruments such as the nebulizer can be soaked in sodium hypochlorite, dried, then used. Especially important in the case of the nebulizer is clean management of the inhalant liquid. In disinfection of the flexible endoscope, the use of an automated cleaning machine has spread. Using Ortho-phthalaldehyde, disinfection with a short immersion time (five minutes) is possible. Finally, to prevent nosocomial infection, it is critical that all medical staff wash their hands properly.
