What angle should the needle be inserted during venipuncture?

The needle should be inserted during venipuncture at a 15 to 30-degree angle to ensure optimal access to the vein while minimizing discomfort for the patient. This angle allows for a balance between gaining sufficient entry into the vein's lumen without penetrating through the opposite wall of the vein, which could lead to complications such as hematoma or accidental arterial puncture.

By keeping the angle within this range, the phlebotomist can effectively target the vein's pathway, which is often flat and easily accessible when approached at a lower angle. This technique also contributes to a smoother, less traumatic process for the patient, fostering better compliance and reducing anxiety associated with blood draws.

Optimal angles are critical in phlebotomy practice, making 15 to 30 degrees the recommended approach for most adults when accessing a vein for blood collection.
