Abstract

Objective : To study pain perception of subjects to evacuated and syringe blood collection system

Study Design : Two group crossover quasi-experimental study (pilot study)

Setting Design : Department of Laboratory Medicine, Faculty of Medicine, Chulalongkorn University

Subject : 30 volunteer subjects

Method : All subjects were randomized divided into two equal groups. The first group was performed venipuncture by syringe blood collection system following by evacuated blood collection system. The second group was performed venpuncture by evacuated blood collection system following by syringe blood collection system. A questionnaire survey about pain perception (visual analog scale) was introduced to all subjects before and after venipunture by each technique. All collected pain scores were then statistically analyzed.

Results : There was no difference of pain score for both venipuncture technique.
