What is the recommended angle of entry for blood draws in hand veins using a butterfly set?

The recommended angle of entry for blood draws in hand veins using a butterfly set is typically around 5 degrees. This shallow angle is ideal when accessing smaller or more delicate veins often found in the hands. Using a lower angle helps to minimize the chance of damaging the vein or causing unnecessary discomfort to the patient. It allows the needle to slip smoothly into the vein without creating excessive trauma. When drawing from the hand's veins, maintaining that gentle entry is crucial for both the success of the draw and the comfort of the patient, ensuring that blood flow is optimal without collapsing the vein. This technique contrasts with drawing from larger veins, where a steeper angle may be utilized.
