Two highly effective methods against all types of microorganisms are ethylene oxide gas sterilization and peracetic acid submersion. Ethylene oxide is noncorrosive and able to penetrate all portions of the bronchoscope without requiring high pressures. However, a venting cap must be placed to equalize the pressure between the interior and the exterior of the bronchoscope. The major disadvantage of ethylene oxide sterilization is that it is time consuming, taking at least 12 to 16 hours to complete the process. An alternative method is the STERIS system (refer to Figure 7-3 in the textbook), an automated, microprocessor-controlled device using a sterilant concentrate, peracetic acid, as the active biocidal agent. This chemical sterilization process requires only 25 minutes. Once the disinfection or sterilization process is completed, the bronchoscope is rinsed with tap water and may be wiped with alcohol before storage in a dry, clean cabinet.
