Keep the bag....do not surrender it to any doctor or the infusion place.
They will try to take it away from you---it is evidence. And keep all tubing and the saline bag also.

If something should result with Alan---and it might take days to show up...
that bag is all you have.

And write down exactly what happened... all the details you recall.
And keep a copy of that too. The time and date the infusion was given,
all of it.

We all hope nothing will happen, but if it does, you need to be prepared for
any legal consequence. People in good health generally may not be at risk for an error
like this....but if mrsa got in there...it might be a different story.
The seminar I attended last Friday had slides showing a desperate man doing his own
occipital (back of the head) blocks with a syringe...no aseptic (clean) technique...he just shot
the lidocaine into his HAIR covered skin... The doctor showing this slide remarked that it was a miracle this patient
did not have an infection yet!
