Comparison of skill in novice nurses before and after venipuncture simulation practice

Abstract

Background: To carry out a successful venipuncture it is necessary to identify a specific point on a vein and maintain stability of the needle tip.

Methods: This study compared the motion of straight and butterfly needles during venipunctures carried out by novice nurses before and after educational intervention. The nurses were videotaped whilst performing venipunctures on a simulated model arm.

Results: The findings of the study showed that butterfly needles were inserted at a greater angle than straight needles. The use of straight needles involved a shorter venipuncture time, with the puncture points being closer together following educational intervention. However, the distance butterfly needles moved during venipuncture was greater after inter-
vention. It appeared that picking-up the wing of the needle caused instability, leading the nurses to place their hand on the model and to have difficulties performing the needle stab. After educational intervention the nurses were able to advance the needle into a blood vessel.

Conclusions: Skin at the puncture point extends and may enter the inside of a vein. It is therefore important to maintain an appropriate puncture point and angle without shaking or rotating the needle. It is also necessary to practice to achieve stable movements of the needle and appropriate movements of the hand.
