Good Morning to you
all,
Another query to my
colleagues on the mailbase please regarding our IL GEM
4000's;-
Firstly, we are
still having problems with cartridge failures on our 4000
analysers. Ours seem to be a mixture of initial CVP failures or a
parameter "fixing" which never resolves (resulting in a crtridge having to be
replaced), or various solution A//B errors. We have been told that no
other sites have this many problems. I wondered if this were true,
particularly as factors such as CVP failures could only be due to us installing
the cartridge in correctly, which is actually difficult to do wrong. This
means there is a consdierable down time when these analysers need to have their
cartridge replaced, the data copied, and be re-calibrated.
Secondly, we have
recently had an issue on SCBU where some completely erroneous results were
obtained on 3 separate occasions, but when the internal data for the analyser
was reviewed, nothing was amiss, according to IL. I have wondered whether
this might be due to the thick film technology that I understand is used on
these sensors, and may be due to the presence of free haemoglobin?
This could have arisen as a result of haemolysis while taking
these (capillary) samples, but the if this was the case, I still am
extremely concerned that result such as undetectable glucose, lactate, and
inappropriate pO2 and pH levels could be reported and potentially acted
upon.
If any of you have
any experiences or could pass this e-mail on to colleagues who may be involved,
I would be most grateful.
Many
Thanks
