Have you ever wondered why in a movie or TV show that a character holding a syringe will "flick" the syringe with a finger? Well, I have the answer. It is just being dramatic. In real life, a veterinarian/veterinary nurses will do this to remove air bubbles trapped in the syringe, although we do it as we draw the drug out of the vial. This step is critical to minimize the possibility of a vascular air embolism (VAE).
VAE is a potentially life threatening, iatrogenic(doctor caused) complication of injecting small air bubbles when making an intravenous injection. These small bubbles can damage the blood vessels and also act an an air lock in the heart.
In this, the 13th. episode of the Clinical Signs Podcast, I discuss what a VAE is, how much air could be lethal to dogs, cats and people, and how we address this issue before making an injection. As added bonuses I discuss the metric system and free radicals.

Thank you and see you soon, Dr. Matt.
