Common Questions and answers:

I cannot get a flashback when I use the butterfly needles or the venous cannulas – do you have advice for me:

Certainly! When using the butterfly needle or the IV cannula, one should see a flashback of blood when successfully entering a vein/fake vein.

The flashback is not a function of the arm/mini-arm. It is not a lousy arm if you don’t get a flashback.

A successful flashback is a function of the following:

  • The venous pressure in the fake vein
  • The gauge diameter of the needle
  • The viscosity of the fake blood
  • Successful entry into the vein with the needle

Let’s discuss these topics one at a time:

The venous pressure in the artificial vein

One can get a better flashback by raising the pressure in the fake vein. Do this by elevating the fluid reservoir bag by about 6 inches (15 cm) at a time.

The gauge diameter of the needle

A smaller diameter needle, e.g., 22 G and higher – gives a slow/weak flashback. A broader diameter needle – 21 G or lower – offers a better flashback. On the downside, large-diameter needles damage the fake veins more and limit the service time of the arm.

It follows that by using a larger diameter needle, one would see a better flashback.

The viscosity of the fake blood

The higher the viscosity, the lower the chances of getting a good flashback. If you use fake blood – it might be a problem as many fake blood recipes include corn syrup, making the blood quite viscous. Real un-clotted blood is fairly non-viscous. We recommend using tap water and a few drops of red food colorant to be used as fake blood. Clean thoroughly after each session of use.

Open the inflow  roller and clip clamps (if applicable)

If any of the inflow clamps are closed – the venous pressure will stay close to zero – and you will not get a flashback.

Successful entry into the vein with the needle

No matter how high the venous pressure and how large-bore needle you use – if you haven’t penetrated the vein successfully – then you will never get a flashback! Suggestion – keep on practicing! Also, if you did not enter the fake vein successfully – then your vacutainer will lose its vacuum, and it will be spoilt.
