When using a straight needle, what is the recommended angle of entry?

The recommended angle of entry when using a straight needle is between 15 to 30 degrees. This angle strikes a balance between ensuring the needle penetrates the skin effectively to access the vein and minimizing discomfort for the patient.

At this angle, the bevel of the needle is positioned correctly to allow for smoother insertion and can aid in facilitating a better view of the vein, which can be crucial for an effective venipuncture. A shallower angle might not allow the needle to penetrate the vein adequately, whereas a steeper angle could risk passing through the vein or causing unnecessary pain to the patient.

Understanding the proper angle is part of ensuring a successful blood draw, making it important for both patient comfort and procedural efficacy.
