I think the official term for these samples is intra-osseous (IO) blood, and
we've had similar discussions with paeds and A&E. For fluid resuscitation with
no venous access the IO route is suitable, but that doesn't mean the samples
are! For biochemistry they mainly need to know the potassium and the
glucose, and the samples are invariably haemolysed anyway. We've suggested
their priority is fluid replacement and they can send a proper venous sample
later. The tests they want either won't change their immediate management
or can't be reliably measured. Was anyone with a lab background involved in
these resuscitation guidelines?
