external jugular vein puncture infants
26
are thin flexible hollow tubes inserted and positioned onto a vein in order to access the bloodstream for the delivery of theraphies

30
prevention of hemolysis during blood collection (venipuncture)
- use sharp smooth needle - puncture the vein directly w/o searching - tourniquet must not be too tight - aspirate blood gently - gentle inversion - if serum is need, do not rim and centrifuge the blood until the clot has formed
