I haven't come across this one, but have encountered requirements for
analysis of pleural fluid and diarrhoea. Our supplier pointed out that
CE marking covers blood gas analysers for blood only.

I think I must have been wicked in a previous life.
Our newly appointed Resuscitation Officer has come to
me and asked if they can put bone marrow samples
through the gas analysers for blood gases. When I
expressed some mild surprise at this request(!), I was
informed that this practice is recommended under the
new Guidlines for Resuscitation laid down by the
Resuscitation Council. A brief discussion with the
blood gas manufacturers got a stunned reply, and the
comment that this would invalidate any warranties.
Bone marrow aspirates contain all sorts of nasty stuff
that would certainly block the analyser nicely. The
Resus officer than came back to me and said OK, not a
good idea then, but can we have U/E on bone marrow?
For those who would like to read this document, go to
www.resus.org.uk/pages/als.pdf. See page 14.It
certainly suggests that when venous access is
impossible, then intra-osseous samples can be used for
gases and U/E. There is no mention of reference
ranges, sample requirements etc. Has anyone else come
across this problem or is it just me?
