改进传统静脉穿刺方法的效果

Effect of improved venous puncture method

目的 通过对改进传统静脉穿刺方法的效果观察,拟推广无痛、低创、快速的静脉穿刺方法.方法 于2008年8月至2009年8月来吉林大学中日联谊医院急救医学科接受静脉穿刺病人中选择2 132例.采用单盲随机法分为改进组1 066例和传统组1 066例.观察比较两组穿刺效果.结果 两种方法疼痛程度的比较差异有统计学意义（Z=21.95,P＜0.01）,改进组优于传统组.两种方法穿刺成功率结果比较差异有统计学意义（x2=36.63,P＜0.01）,改进组可提高一次性静脉穿刺成功率.两种方法回血时间比较差异有统计学意义（u=196.50,P＜0.01）,改进组进针方法进针后回血速度快.两种方法穿刺点出血及皮下淤血的比较差异有统计学意义（x2=11.76,P＜0.01）,改进组拔针后穿刺点出血及皮下淤血发生率低.结论 改进传统静脉穿刺方法能不同程度地减轻病人的痛苦,穿刺成功率明显优于传统的静脉穿刺方法,值得临床推广.

Objective To observe the effect of improved venous puncture method and provide basis for popularizing the method which is rapid, painless and of less trauma. Methods According to single-blind random method, 2 132 patients undergone venous puncture treatment in the emergency department of our hospital from August 2008 to August 2009 were selected and divided into two groups： improved group （ 1 066 cases） and traditional group（ 1 066 cases）. Observed the effect of two groups. Results Improved method was superior to traditional method in pain easing, and there was statistical difference between the two groups （Z = 21.95 ,P 〈0.01 ）. Improved method could increase puncture success ratio, with statistical significance as compared to traditional method （ x2 =36.61 ,P 〈0.01 ）. Also, zhe former had more rapid venous return （ u = 196. 50,P 〈0. 01 ） and less incidence of bleeding of penetration points and subcutaneous ecchymosis after needle withdrawing （ x2 = 11.76 ,P 〈 0. 01 ） than the latter. Conclusions Improved puncture method is of less pain and higher puncture success ratio and is superior to the traditional method.
