SterilizationPregunta 46 de 100

A tray wrapped in a cellulose-based (paper) wrapper is about to be loaded into a hydrogen peroxide gas plasma sterilizer. What is the problem?

a.Cellulose reacts with hydrogen peroxide to form a toxic residue on instruments
b.Cellulose absorbs hydrogen peroxide and will cause the cycle to abort or fail, so only nonwoven polypropylene wrap and compatible trays may be used
c.Cellulose wrap melts at the operating temperature of the sterilizer
d.Cellulose wrap is acceptable if a second wrapper is applied over it

Explicación

Hydrogen peroxide is readily absorbed by cellulose materials such as paper, linen, and cotton, which strips sterilant from the chamber and causes cycle cancellation, so only polypropylene wrap, compatible pouches, and approved containers are used. The issue is absorption, not toxic residue formation or melting, since the process runs at low temperature. Adding a second cellulose layer makes the absorption problem worse.
