Q.1.What
is the most common problem with stainless steel instruments?
Ans:
The most common problem with the stainless steel instruments is a stain
due to a surface deposit, which appears in different colors. But once the
cause is found, the problem diminishes completely. For detail please go
through the PARVEEN INTERNATIONAL recommendations for instruments cleaning.
Also go through the PARVEEN INTERNATIONAL CHECK LIST for our Analysis Report about Instrument Care
Q.2.What should be the
composition of water for decontamination and cleaning the instruments?
Ans:
Never use the drinking water for decontamination and cleaning because it
may contain such material concentrations, which deteriorate the
instrument.
Chloride contents must be kept as low as 100mg per liter to reduce
corrosion risk.
Q.3.What are the Causes and
remedies of water stains and halos?
Ans:
Halos are colored surface marks, which result from the presence of mineral
substance or heavy metal ions in water or cleaning steams.
Water stains are almost similar phenomena but their contours are sharp.
They result from residue of organic substances in water or in an excessive
concentration of mineral substance such as limestone.
Q.4.What are two reasons behind
colored surfaces residue on the instruments?
Ans:
Some yellowish brown to dark
brown residue is sometimes mistaken as rust stains on the instruments.
This is common in the least accessible areas during cleaning.
These deposits can be eliminated buy energetic friction or by using
non-abrasive cleaner.
Q.5.What are the causes of
oxidization on surgical instruments?
Ans:
If the surgical instrument are soaked in concentrated acid solutions for
long periods of time.
In this case, the surface of the instruments gives a trusted look this
comes from the formation of an oxide film in places.
Q.6.How to avoid pitting
corrosion on the surgical instruments?
Ans:
This is most frequent form of corrosion associated with multi colored
stains and consists in the forming of holes in material. Such corrosion is
caused by halogen ions (Chlorides, Iodine, bromides) working on the
surface and resulting for saline solutions or other chlorides.
To prevent this type of corrosion instruments should be cleaned as soon as
they have been used.
Q.7.Is
there any instrument cleaning recommendations established by PARVEEN
INTERNATIONAL?
Ans:
After the experience and research PARVEEN INTERNATIONAL has developed the
following recommendations for cleaning procedures; instruments will have a
longer useful life.
STEP I
(Soaking)
After the instruments have been used, dip the instruments in a quality
soak. Before putting make sure about blood, tissue or both debris from
hardening in serrations, box joints and moving parts.
STEP II
(Brush
the Instrument)
Instruments must be hand cleaned with some suitable solution using nylon
brush.
STEP III
(Cleaning)
Use only quality
detergents. Keep the instrument in wide-open position while cleaning.
STEP IV
(Inspection)
After Cleaning, the instrument must be thoroughly inspected, especially;
smooth movement of instrument and sharp edges.
STEP V
(Lubrication)
Lubrication prevents the moving parts form jamming and keeps the
instrument in efficient working condition. Lubricant used must be good
water-soluble.
STEP VI
(Sterilization)
After cleaning and lubrication, the instrument must be dried before
sterilization. Autoclave is the best method of sterilization
recommendation by PARVEEN INTERNATIONAL.
