Clean versus sterile
Cleaning removes soil and reduces contamination; sterilization aims to eliminate viable microbes including spores under validated process conditions.
Sterile field
Prepared instruments, barriers and controlled handling reduce contamination; if sterility is uncertain, the item should be treated as nonsterile.
Skin and hand preparation
Appropriate hand hygiene, antiseptic skin preparation and safe glove use are complementary rather than interchangeable.
Quality checks
Instrument reprocessing, indicators, audit and staff training reduce preventable lapses across a surgical service.
