This is a Cochrane review of the use of saline in Bronchiolitis. The authors have looked at all studies with a helpful differentiation between hospital and out patient (ED) studies.
We see lots of kids with rashes in ED, most brought out of an intrinsic anxiety that the rash represents something sinister - and none more so that those with spots which don't fade.
One such dogma is that 'Children are not little adults'.
I'm an APLS instructor & course director and have contributed various bits and bobs over the years and it's a great course. I'd go further and say that it's a really great course to get a grounding in Paeds resus that has made a real impact to paediatric care around the world.
If I think back to my practice a few years ago (as I'm getting older) there is no doubt that the number of CT scans I've performed from the ED has increased. In both my adult and paediatric practice the indications for CT have increased, the ease of obtaining a scan has decreased and as a result I've almost certainly delivered many more mSieverts in the last year than say 5 years ago....., but does this matter?
