Instrument Decontamination
Methods that Prolong Instrument Life
-- by Michael Hales |

Proper handling of stainless steel surgical
instruments and exercising the best decontamination practices can dramatically increase
each instrument's life. Because of budget constraints, many hospitals, clinics, and
medical offices have a mix of expensive, largely German stainless steel instruments and
those of lesser quality. Inexpensive instruments are not expected to last long and
often break down quickly upon repeated exposure to organic material, cleaning solutions,
rough handling, and mechanical washing.
When deteriorating instruments are combined
with higher quality instruments in a basket during decontamination, migration of surface
rust, stains, and discoloration can occur. Just one bad instrument can transfer rust
deposits to others. Separation of deteriorated instruments during cleaning, along
with a variety of other techniques should be applied to prolong instrument life.
The "New Car" Syndrome
New, state-of-the-art instruments are a
tribute to the creativity and craftsmanship of doctors and designers. It is easy to
regard these instruments as virtually impervious to attack by chemicals or other
substances, and initially, they resist damage. It is like getting a new car.
At first, the the finish is smooth, shiny, free of scratches and chips, and resists
attacks of weather and washing. But in time, the finish gets scratched or chipped,
the car's metal body is exposed and loses its barrier. Likewise, as an instrument is
processed repeatedly, its surface can be compromised and breakdown. It is important
to understand cleaning process and recognize various types of corrosion and discoloration
to avoid premature breakdown.
