The purpose of this study was to determine safe techniques of performing blood collection using an evacuated tube system, particularly with regard to manipulation of the equipment and at the puncture site. Careful observation of the procedure was used to collect data for evaluating the various venepuncture techniques. Nurses were digitally videotaped performing simulated venepuncture. A self-administered questionnaire and unstructured observation of a videotaped recording were evaluated, and valid responses were analyzed from participants who performed venepuncture using various techniques. The participants who changed hands during the procedure were older than those who did not change hands. Needle movements during puncture and insertion, including rotation and insertion in a wave-like trajectory, were observed. Appropriate training, including recommendations for maintaining the stability of the needle tip, is important to ensure safety when performing venepuncture. Movement of the needle should not place too much pressure on the puncture site.
本研究的目的是确定使用真空采血管系统进行采血的安全技术，特别是在设备操作和穿刺部位方面。通过仔细观察该过程来收集数据，以评估各种静脉穿刺技术。护士进行模拟静脉穿刺时被数码录像。对一份自我管理的问卷和对录像记录的非结构化观察进行了评估，并对使用各种技术进行静脉穿刺的参与者的有效回复进行了分析。在操作过程中换手的参与者比未换手的参与者年龄更大。观察了穿刺和插入过程中的针头移动，包括旋转和呈波浪状轨迹插入。适当的培训，包括保持针尖稳定性的建议，对于确保静脉穿刺时的安全很重要。针头的移动不应在穿刺部位施加过大压力。
