    Hey everyone, I was wondering, is there a significant difference between blood sugar measurements at the

    I am trying to figure out if there is any difference between checking blood sugar on a patient via the arterial method vs the finger stick method?  Is it any more accurate to check it arterially if you’re probably gonna need an insulin drip?

    Thank YOU!

    It’s usually arterial as being the most accurate and the gold standard, followed by central lines then finger stick.

    . If a patient doesn’t have a central or arterial line then I will do a finger stick. But if they need to have blood sugar checks every hour then I think they are a candidate for an arterial or central line. No patient wants to be stuck every hour.
