what size of IV catheter should I use for geriatric or old pt?
Interesting question about the right size of IV Cath for geriatric pt. In my own experience, I usually use 22-20 ga needle for IV insertion. Old pt usually have really thin skin or sensitive skin, and very easy for skin tear. I always use less trauma to skin as much as possible, don’t have to use bigger IV cath if you’re not going to do a blood transfusion or even infusing PPN (peripheral parenteral nutrition). If the pt is hard stick then I ususally try using 24 ga like the one I use for pediatric pt. After awhile though, you will notice a leakage on your IV infusion so be very vigilant on checking your IV site at least once every shift.
