Title: IV size for CTP
Post by: lbraikov22 on January 18, 2019, 11:13:54 am
What is the iv size you are using for CTA Brain Perfusion?
Do you use a 20g if an 18g is unattainable?

We currently request 18g antecubital iv from our Neuro ICU, however, they often complain that they can not obtain an 18g and want us to do it with a 20G, we have done it in the past but we find the scans not as good and often at 5cc/sec the iv blows.

Thank you

A 20 will work but an 18G is ideal. A solution is to use the BD Nexiva catheter. These at 20g can handle 10cc/sec contrast so it will solve your problem.
here is some info
