Study Notes
Obtaining Blood
- There are three general procedures for obtaining blood:
- Not specified in the provided text, but generally, they are Venipuncture (phlebotomy), Arterial Puncture, and Fingerstick (Capillary Puncture)
Capillary Blood
- Capillary blood is frequently used in pediatric and neonatal patients, as well as in situations where venipuncture is not feasible
- Advantages of capillary blood include ease of collection, minimal trauma, and low risk of complications
Puncture Sites
- For adults and children, the most common sites of puncture are the medial cubital vein, the basilic vein, and the cephalic vein
- For infants, the most common site of puncture is the heel (plantar surface)
Factors That Increase the Risk of Hemolysis
- Using a needle that is too small can increase the risk of hemolysis
- Jostling and jarring of tubes in transit can cause the RBCs (red blood cells) to rupture
- Pressing the syringe plunger to force the blood into the small tube or needle can also cause hemolysis
- Drawing a blood specimen from an intravenous or arterial line can increase the risk of hemolysis
- Under filling a tube so that the ratio of anticoagulant to blood is greater than 1:1 can also increase the risk of hemolysis
