Q

How do you prevent hemolysis?

A
  1. Problem free venipuncture
  2. Use a larger bore need to draw – 21, 22, 23 gauge
  3. Use larger needles for transferring blood into test tubes – 18g blunt fill works well
  4. Tilt blood tubes so that the blood washes down the side of the tube
  5. Aspirate slowly when collecting from veins or catheters

Q

What should we know about blood culture collections?

A
  1. priority to minimize risk of contamination
  2. Blood cultures when ordered, should be collected FIRST
  3. 5-10mL of blood should be collected for each sample
  4. Never attach blood culture bottles directly to vacu-holders because beads in the culture bottle can be introduced int the patients vein

Q

Trouble shooting peripheral and CVAD blood draw?

A

No blood or an incomplete collection…
1. change the position of the needle
2. Tourniquet too tight– could obstruct blood flow
3. Change tubes- vacuum could be a problem
4. Re-anchor the vein- some veins roll
5. Have patient make a fist to help engorge muscles
6. Pre-warm area of venipuncture to increase blood flow
7. Re-hydrate patient
