How long should pressure be applied to the injection site after blood draw?

When performing a blood draw, it is essential to apply pressure to the injection site to prevent bleeding and promote the formation of a clot. The recommended duration for applying pressure is typically 30 to 60 seconds. This amount of time is effective in allowing hemostasis to occur without risking excessive bruising or discomfort for the animal.

Applying pressure for 30 to 60 seconds ensures that blood vessels close adequately, which reduces the risk of hematoma formation at the site. This practice is crucial because it helps maintain the integrity of the tissue and minimizes complications that may arise from insufficient closure of the blood vessel.

While pressing for durations longer than 60 seconds might still be acceptable in certain situations, it is generally unnecessary for most blood draws unless specific circumstances warrant it. Therefore, the choice of applying pressure for 30 to 60 seconds strikes a balance between effectiveness and practicality, aligning with standard veterinary practices for managing injection sites following blood collection.
