Q94 marksShort Answers★✓

Answer

Four gaseous sterilants:

1. Ethylene oxide (ETO).
2. Formaldehyde gas.
3. Hydrogen peroxide gas plasma.
4. Ozone gas.

Two uses of Ethylene oxide:

1. Sterilization of heat- and moisture-sensitive medical devices (plastic tubing, catheters, electronic components, complex-lumened endoscopic instruments) that cannot withstand steam autoclaving.
2. Sterilization of pre-packaged, single-use disposable medical items (syringes, surgical gloves, sutures) during industrial/large-scale manufacturing.
