I seem to have a small collection with one update being slightly more up to date.
DOH - Good practice guidelines for renal dialysis/transplantation units - 2002
RA Guideline - Blood borne Virus infection - 2009
DOH - Good practice guidelines for renal dialysis/transplantation units-addendum 2010
"External cleaning After each session, the exterior of the dialysis machine should be cleaned with a low-level disinfectant if not visibly contaminated. If a blood spillage has occurred, the exterior should be disinfected with a commercially available tuberculocidal germicide or a solution containing at least 500 p.p.m. hypochlorite (a 1:100 dilution of 5% household bleach) if this is not detrimental to the surface of dialysis machines. Advice on suitable disinfectants, and the concentration and contact time required, should be provided by the manufacturer."
Is that correct in my COBE manual it says 1:9 dilution giving 0.5% solution ,that's what we have been recommending for our branded bleach ?
This seems to have been taken from and old KDIGO guideline for prevention of Hep C transmission, I can't see that the updated (2018) guideline gives any recommendation of hypochlorite level.
Our IPC would say 10000ppm for a blood spillage anyway, and I don't think any equipment manufacturer would sanction this strength. We moved a away from bleach a long time ago.
A hypochlorite product of 10,000 ppm. This can be in the form of granules, e.g.,Haz tabs, or a solution, i.e.,Milton 2%,using 1 part Milton to 2 parts water. (Household bleach can be used –usually 1 part bleach to 10 parts water –but check manufacturer’s instructions.
I agree, but still think it should be 1:9 ratio to give a 0.5% solution rather than 1:10 stated or is my maths wrong ?
