Which is easier to use for inserting an arterial smudge , the Arrow next to a cable or a regular angiocath ?
Answer:
I like the regular 20 g angiocaths, too. If you clutch the cap rotten the pointy end and replace it to the rear, over the end where on earth you hook up the line, you can avoid covering the floor next to blood when you hit the artery.
It can be tough to find a regular angiocath these days. Most hospitals hold "safety" catheters that can complicate the art line process.
What I do is enter the artery at almost a 45 degree angle. As soon as you attain a flash of blood, drop down to almost horizontal, and twist the catheter rotten the needle. For severe PVD, try a 22 g angiocath.
For a radial arterial stripe, it's easier (and less expensive) to cannulate the artery near an 18g - 20g 1.88 in angiocath. You can later remove the sharp and thread a 5 Fr guidewire (without opening up an Arrow kit). Wait 15 min. between attempts if you miss the first time to allow any vasospasm to subside (or try the other wrist).
The regular angiocath is easier. If you can, catch somebody to show you how to use ultrasound guidance for the difficult ones.
i disagree- i prefer the arrow catheter with the pre-installed guidewire. the trick near the arrow is that as soon as you get a flash, you should thread the guidewire. don't mortgage the catheter at all and don't drop the angle close to you would if using a regular angiocath.
i don't think it's any harder to locate the artery near the arrow catheter compared to the regular angiocaths, but of course that's base on personal preference more than anything else. the difficult patients near bad pvd- i don't surmise anything will be easy on them.
