When you first get flash, the bevel of the needle is in the lumen of the vein. If you thread the catheter from here, you'll likely blow the vein as the end of the catheter may still be in the wall of the vein (it sits BEHIND the bevel of the needle). When you see flash, pause, lower your angle of insertion, advance another 2-6mm depending on gauge, THEN thread the cat

But how do we know what 30 degrees looks like? . If the needle is straight up and down that’s 90 degrees. Cut that angle in half and that’s 45 degrees. 2/3 of that is 30 degrees. . The more superficial the vein is, the shallower your angle of insertion should be. . If tips like these are helpful, there’s a lo
