旋转式静脉注射方法的应用观察

鉴于临床常规静脉注射法存在的弊端，改垂真法为旋转法注射，并通过扫描电镜观察两种注射方法产生的微粒数，用Ｗｏｎｇ－Ｂａｋｅｒ面部表情量表评估病人对两种注射法疼痛的反应。结果显示：旋转组药液中１０μｍ￣２５μｍ微粒数明显少于垂直组（Ｐ〈０．０５），采用旋转法注射组病人疼痛反应也明显轻于垂直法注射组。

Improvement of the Way to Give Intravenous Injection

In view of some disadvantages do exist in the way of routinely intravenous injection. We changed the way of vertical injection into rotary injection. And numbers of particles this two different way of injection produced were observed through scanning electron microscope. Patient's pain reaction to injection was evaluated via Wong-Baker Facial Expression Scale. Results showed numbers of particles in rotary injection group were markedly less than that in vertical injection group (P<0.05). And patients had less pain reaction to injection in rotary injection group than that in vertical injection group.
