Title: 20g vs 22g for CTA work
Post by: dolinger1 on May 28, 2019, 12:59:22 pm
My new job insists i use only 22g catheters for r/o PE & CTA studies. I’m not comfortable with this.
How do i make them understand why we use 20g carbs and not 22g??

you should at least use the B and D catheters so that you can inject 5 cc thru a 22g
these are the Nexiva catheters
