What keeps surgical equipment sterile?
Autoclave:- An autoclave uses pressurized, highly saturated steam that sterilizes by denaturing proteins.
Chemical sterilizers (like 80% Ethanol / Isopropanol):
- High-level disinfectant for surfaces.
- Sterilizes in approximately 10 minute contact time but can affect metal equipment in the long term if they have a high-concentration
Glutaraldehyde
- Intermediate-level that requires long exposure times
Quaternary ammonium chloride compounds (QUATS, for noncritical) - Disinfect
Vaporized hydrogen peroxide (VHP or VH2O2)
- A relatively new form of sterilization
Irradiation (EB/ E-BEAM or Gamma radiation)
