高压注射器腕上区“平行”静脉穿刺法效果观察

Observation the effect of high-pressured injector wrist area "parallel" venous puncture.

目的:观察高压注射器腕上区平行静脉穿刺法的效果。方法:应用高压注射器静脉注射对比剂行CT增强扫描患者2929例,分成观察组1292例和对照组1637例,对照组按照常规穿刺,观察组采用腕上区平行静脉穿刺法,比较两组对比剂外渗发生率、一次穿刺成功率。结果:观察组一次穿刺成功率明显高于对照组,对比剂外渗发生率明显低于对照组(均P<0.01)。结论:腕上区平行静脉穿刺方法能明显提高一次穿刺成功率和CT增强扫描成功率,能有效减少对比剂外渗。

Objective：Observation the effect of high-pressured injector wrist area parallel venous puncture.Methods：Scans the patient 2 929 examples using the high-pressured injector intravenous injection contrast agent line of CT enhancement,divided into the observation group 1 292 examples and the control group 1 637 examples.The control group according to the conventional puncture,the observation group uses on the wrist the area parallel venous puncture.To compare contrast agent extravasations formation rate,a puncture success ratio of two groups.Results：The observation group puncture success ratio obviously is higher than the control group.The contrast agent extravasations formation rate obviously is lower than the control group （all P0.01）.Conclusion：On the wrist the area parallel venous puncture method can raise a time puncture success ratio and the CT enhancement scanning success ratio obviously,can reduce the contrast agent extravasations effectively.
