We have discovered three blood collection needles that provide vein entry indication of proper needle entry prior to attaching the collection vial.  No more prodding while the needle is sucking in tissue, veins, nerves!  Vein entry is seen as flashback, the tell-tale sign the needle is inside a vein.  Whether a patient is infim, an infant, obiese, or simply has hard to find veins, the devices will work 100% of the time and only cost pennies to manufacture under brands including BD, Greiner Bio One, Terumo.  Why aren't we using these 2nd generation safety needles?

Venous Blood Sampling

 

1- Apply a tourniquet proximal to the

venepuncture site.

2- Tap on or rub the skin overlying the

vein you want to puncture lightly to

make it standout; or if the vein is

obscure, you may be able to palpate its

course with you index finger.

3- Sterilization with alcohol and leave to

dry in air

(traces of alcohol causes hemolysis)

4- Hold the syringe between the thumb

and the middle, ring and small finger of

your dominant hand and steady the

needle using your index finger

.

" Never hold the syringe like a pencil because it limits your angle of skin

entry "

5- confirme entry of the vein by

aspiration of blood, Once the desired

volume of blood is aspirated into the

syringe, steady it with one hand and

release the tourniquet with the other

hand.

6- Use a piece of dry gauze to apply

gentle pressure to the entry site while

the needle is withdrawn. Ask the

patient to continue to apply pressure

while you attend to the specimen

obtained .

7- Remove the needle from the syringe

and drop it into the special box for

disposal of sharp instruments

immediately .

8- Uncap the specimen container and

deposit the blood sample into it directly

from the syringe. Injecting blood into

the container via the needle is not

advisable because:

(a) you may prick

yourself and

(b) forcing blood through the needle may cause hemolysis that

can adversely affect the analytical

fitness of the specimen.

■ Avoid hemolysis:-

Allow alcohol to dry

Clean tubes

Withdraw blood slowly

Do not use too fine needle

Deliver blood gently to the tube Avoid frothing
