Know your enemies
|
water and moisture of any kind are the primary caused of marks and stains on instruments (blood,pus,surgical debris, chlorhexidine solutions)
|
|
know your enemies
|
do not allow your instruments to air dry this can cause irreversible damage
|
|
enemies
|
do not cold soak in anything except an approved solution
|
|
understand the causes of corrosion
|
the primary corrosivce sulprits are surgical residues, tap water, cleansers, and surgical towels and drapes
|
|
surgical residues
|
blood, tissue, contain chloride ions that cause coorosion. with autoclaves: remember an autoclave does not clean it only sterilizes
|
|
tap water
|
container a high concentration of minerals. rinse instruements with disillted water, thoroughly towel dry immediately after washing. Or with the autoclave-extend the drying cycle of sterilization. this reduces the risk of condensation on instruments.
Wet surgery packs usually result in stained instruments |
|
cleansers
|
nonapproved cleaning agents cause corrosion
those containing acid or alkaline agents lead to pitting and staining. opimal ph = 9.2 to 11 do not use prvidone-iodine dish or laundry detergent surgeion's hand scrub. these cause spotting and corrosion. use a non-metal instrument-cleaning brush. |
|
surgical towels and drapes
|
if you recyle laundry, use as little detergents as possible when laundering. use an extra rinse cycle. the residue detergents corrode the surgical instruments
|
|
test for rust
|
rust leaves permanent damage. rubbing a pensil eraser over a mark; if the mark is removed the mark is a stain, if their is a pit the mark represents corrosion or rust
discard rusted instruments immediately. |
|
clean immediately after surgery
|
washing process should begin within 10 min. after surgery. washing the instruments within a few minutes of surgery is the best defense against corrosion, pitting, and staining.
|
|
sterilize
|
all surgical instrument must be sterile.
sterilize instruments with their jaws open. never stack paper or plastic pouches on top of each other in the autoclave. stand them up on a holder |
|
ultrasonic cleaning
do not place dis-similar metals together |
16 times more efficient than hand cleaning. place instrument in a neutral-pH solution in the ultrasonic unit for 10 minutes.
|
|
clean autoclaves regulary
|
use only distilled water in the reservoir.
clean the filter regulary. clean the chamber once a week. |
|
lubricate instrument regulary
|
lubricate after every cleaning.
"instruments milk" |
|
never use cold sterilization
|
not recommended it shortens the life of surgical instruments. never leave immersed for more than 20 min. never immerse tungsten carbide inserts in solutions containing bezyl ammonium chloride.
