摘要
[目的]探讨真空采血法与传统采血法的合理选择,提高老年病人静脉采血的成功率。[方法]采用平行随机化对照实验的方法选择40 0例行静脉采血的老年病人,随机分为真空采血组(A组)和传统采血组(B组) ,每组2 0 0例,比较两组的失败率并分析失败的原因。[结果]真空采血法在血管条件不好且采血管数≥4时,失败率明显上升,建议选择传统采血法。采血管数≤3时,因对检验结果影响较小,成功率与传统采血法相比差异不大,选择真空采血法为宜。采血管数≥6时,总采血量一般>2 0mL由于传统注射器型号及容量的限制,选择真空采血法更为方便。[结论]护理人员应根据病人的血管条件及采血量灵活选择采血方法。
Objective:To probe into reasonable chosen of vacuum blood collection or traditional blood collection method, in order to raise the success rate of venous blood collection for senile patients. Method:A total of 400 senile patients underwent venous blood collection were divided into vacuum blood collection group (group A) and traditional blood collection group (group B) equally in a parallel random control way. Then the failure rates of blood collection of the two group patients were compared and the causes of failure of blood collection in the two groups were analyzed. Result:The failure of vacuum blood collection would increase if the conditions of blood vessel were poor and the number of blood collection test tubes was ≥4. In this situation, blood samples should be collected in traditional way. When the number of blood collection tube was ≤3, for it has less influence on test results, in this occasion vacuum blood collection is supposed to be selected. And it is convenient to adopt vacuum blood collection method when the number of blood collection test tubes is≥6, and the total volume of blood collection is > 20 mL, because of the limitation of traditional syringe types and its capacity. Conclusion:Nursing staff should adopt blood collection methods reasonably, based on the conditions of blood vessel and blood collection volume of patient.
