6. STEAM STERILIZATION • The best form of sterilization whenever permissible • 1210C 15min • 1340C 5min • Open instruments • Laparoscopic instruments • Modern telescopes • Long channels Flash sterilization – • Not a replacement • Do not pack instruments

7. ETHYLENE OXIDE (ETO) • Sterilizant for moisture and heat sensitive instruments • Gas concentration (450 to 1200 mg/l) • Temperature (37 to 63°C) • Relative humidity (40 to 80%) • Exposure time (1 to 6 hours) • Plastic wrapped stuff • Long channels • Problem – • Flammable • Environmental pollution • Neurotoxic and carcinogenic

9. STERRAD® : H2O2 plasma • Sterilization of heat sensitive instruments • Temperature <55°C • Exposure time <60 min • Advantage – • Short cycle • Non-toxic effluent • Efficacy against PRION • Disadvantage – • Luminal instruments

13. FORMALIN CHAMBER • No standardization • How many pills? May be 10-15 tabs • How frequent changes? May be 7-10 days • How much time? At least 24hrs for disinfection, 96hrs for sterilization • Penetration into lumens – uniformly poor • Pulmonary toxicity • carcinogenicity Suzuki A, Namba Y. Nagoya J Med Sci 1982

33. Conclusion • Instrument mechanical cleaning is A MUST (not an option) • Never forget to FLUSH and BRUSH the channel • Sterilization and HLD is not a substitute of mechanical cleaning • Do not cut corners in immersion time

34. Conclusion • Instrument mechanical cleaning is A MUST (not an option) • Never forget to FLUSH and BRUSH the channel • Sterilization and HLD is not a substitute of mechanical cleaning • Do not cut corners in immersion time
