9. Disinfection
During dialysis flow, bacteria usually do not colonize or adhere to
surfaces. Therefore, if the dialysis machine is kept running, it may
be unnecessary to disinfect between dialysis treatments (Bland &
Favero, 1990).
The highest sodium hypochlorite concentration for which the
Instrument is designed is 5.25%. If 6% is used, it will be
necessary to dilute it with RO water.
CAUTION
Using 6% bleach may accelerate damage to internal fluid
path components.
How to make 5.25% bleach from 6%
• To a 96-ounce container of Clorox Ultra, add 14 ounces of
RO water.
• To a 180-ounce container of Clorox Ultra, add 27 ounces of
RO water.
• If you are using a 1000 mL disinfect bottles, use 875 mL of
6% bleach and 125 mL of RO water.
The formula to calculate the amount of water to be added to
achieve the proper dilution is:
Volume of 6% bleach X 0.143 = Amount of RO water
needed.
Example: 875 mL of 6% bleach X 0.143 = 125 mL of RO
water.
CAUTION
The Clorox Company has another product called Clorox
Advantage that is packaged in a container with a similar
label. This product contains a fair amount of added
sodium hydroxide. The combination sodium
hypochlorite (bleach) and sodium hydroxide (caustic
soda) is definitely NOT something that should be used
in a Baxter Instrument!
Do not use Clorox Advantage in any Baxter
hemodialysis Instrument. Damage will occur to internal
fluid path components.
9.4.1.2 Amuchina
Amuchina is described as an electrolyte chloreoxidizer. It is a
sodium hypochlorite solution which is manufactured by the partial
electrolysis of sodium chloride. Amuchina is 18% sodium
chloride and claims that tests have shown it to be nontoxic to skin
