"Alternative" Ultrasound uses

[DAVID LONGSETH]

Is there anyone using an ultrasound for uses other than PICC's? I know the 
peripheral IV issue was recently discussed,but what about some others such 
as blood draws,ABG's and arterial lines? I have used our machine,in some 
very unusual circumstances,to get both venous and arterial blood samples. I 
take an art. line class next month and have found a few references on using 
US for this.
