Dear All,
Just sharing my though on hydrogen peroxide wipe.
Our sites are thinking of trialing hydrogen peroxide ( H202) wipes ( Diversey Oxivir Tb - 5% Benzyl alcohol & 1% hydrogen peroxide, SciCan Optim Blue - 0.5% hydrogen peroxide ).
I was worried about H202 contamination that might cause severe issues like hemolysis.
Thus did a quick test wiping a Diversey Oxivir Tb wipe on a dialysis machine screen in the workshop followed by a couple of H202 test strip from Serim.
Between the time when the screen was wiped with Oxivir and 6 minutes later, H202 was at 10 ppm or beyond Between 7 and 12 minutes, H202 was about 5 ppm .
Between 13 and 14 minutes , H202 was about 1 ppm .
After 15 mins, H202 was 0 ppm thus undetectable .
Does anyone has a similar concern as me, tried using H202 wipe or did similar test ?
Thank you and have a great day

The only way I can see a disinfectant causing hemolysis would be if it got into a patient's blood. I don't see your product posing a greater risk than bleach. I noticed that CMS says staff should use 1-100 bleach or a tuberculocidal disinfectant on surfaces. I assume Diversey is a tuberculocidal disinfectant.
Does it cause any problems with the display screen?

Thank you for sharing. It is Tuberculocidal thus will serve the same purpose as bleach but less hazardous in addition to being bactericidal and virucidal.
At the moment, there no effect on the screen and actually it is much more clearer and cleaner

We used the Oxivir TB wipes for years before switching to McKesson wipes. The Oxivir wipes actually got our bleach damaged screens looking brand new again.
I don't understand your concern of hemolysis?

Thank you for the information especially about the recovery of damaged screen and McKesson wipes. I was concerned about accidental contamination of hydrogen peroxide residue in the closed circuit ( through dialyzer coupling , concentrate rinse chamber , bicarbonate holder etc) and blood circuit ( online /substitute / HDF port) .
There been cases of hemolysis reported by others caused by contamination of hydrogen peroxide in the RO permeate after RO disinfection due to insufficient rinsing.
