Learning Objective 1: The learner will be able to know the characteristic of the peripheral intravenous skills of fresh nurses and veteran nurses.

Learning Objective 2: The learner will be able to know the angle and speed of the needle of fresh nurses and veteran nurses.

Purpose: To elucidate the characteristics of skill in venipuncture with a peripheral-short catheter by new, and experienced nurses.

Methods: This study targeted 3 new nurses(less than 1 year of experience), 3 experienced nurses(4 or more years of experience), wherein their skill in venipuncture was observed by Three Dimensional Motion Analyzer (VICON) and video recording. The venipuncture was defined as “From pricking skin with a needle to just before insert a catheter”. We attached two 6.35mm markers to the catheter of 22G and measured the three-dimensional coordinate at 100Hz. Nurses stabbed the arm of model with the catheter with markers,was implemented under the same environment (laboratory).We measured the change of the angle of the needle and speed to prick based on two points of coordinates. Seirei Christopher University Ethical Review Board was approved.

Results: experienced nurses changed smoothly an angle while putting a needle. Experienced nurses sting a catheter faster than new nurses. When new nurses carry out venipuncture, an angle changed suddenly and irregularly.

Conclusion: experienced nurses perform intentional angle adjustment. In experienced nurses, speed to stab are fast. new nurses are unstable in a needle at the time of venipuncture.
