服用小剂量阿司匹林老年冠心病患者静脉穿刺后局部按压时间的研究

目的探讨平时服用阿司匹林的老年冠心病患者静脉穿刺后合适的按压时间。方法选择我科收治的小剂量口服阿司匹林的老年冠心病患者30例，每位患者均接受16次静脉穿刺，按按压时间不同共分为8组，观察患者皮下出血的发生情况、出血面积，并进行统计分析。结果平时服用小剂量阿司匹林的老年冠心病患者经静脉穿刺后，局部按压时间与患者皮下出血、出血面积密切相关。按压8min与按压9min的皮下出血情况与面积相比，差异显著（P〈0．05），其他相邻组间的出血率与出血面积比较，差异不显著（P〉0．05）。结论对于平时口服小剂量阿司匹林的老年冠心病患者，经静脉穿刺后局部压迫9min为合适的时间，既不会影响血液供应，又可使皮下出血发生率降低、并使局部出血面积缩小。

Local Press Time of Senior Patients with Coronary Heart Disease Taking Aspirin Orally after Venous Puncture

Objective To study the effect of local press time of senior patients with coronary heart disease who take aspirin. Methods Selectd 30 low-dose aspirin-taking senior patients, treated with 16 time venous puncture and divided by press time into 8 groups. Observed separately the incidence and area of subcutaneous hemorrhage, process data statically. Results Local press time of senior patients with coronary heart disease taking aspirin orally after venous puncture was correlated to incidence and area of subcutaneous hemorrhage. Through comparision of incidence and area between 8 minute and 9 minute press, there was statistical significance （P 〈 0.05 ）, the incidence among neighboring groups showed no statistical significance （ P 〉 0.05 ）. Conclusion For low-dose aspirin-taking senior patients with coronary heart disease, 9 minute press is appropriate after venous puncture, and this also has no effect on blood supply, reduce incidence of subcutaneous hemorrhage and area.
