What length of catheter are you guys using who are placing Basilic IV's under US using for patients with difficult access? I have used this technique some lately and am still trying to work out kinks since I am 'pioneering' technique at my hospital. Used regular 18g on first two. They ended up working their way out of vein. No longer catheters are available right now. Have used tricked up version with femoral aline kit. Total overkill, but best option with supplies at my disposal. Is a 2inch 18g long enough to do the trick?
