Needle Positioning

Correct Angle of Insertion

  • The angle of insertion of the needle should not fall below or exceed 15 - 30 degrees.

Needle Positioning: Safety and Notes



  • Do not "dig" or "probe" for the vein.  "Digging" for veins can cause nerve damage, and damage to the veins and surrounding tissue resulting in bruising and pain to the patient.
  • Do not reinsert needles if they came out of the patient while trying to find the vein.  Reinsertion of needles can increase the chance of causing infection.
