3种不同采血途径测定凝血酶原时间的对比研究

Contrastive Study of Three Different Ways to Determine Blood Prothrombin Time

目的经外周静脉、动脉测压管和中心静脉留置管采血标本测定凝血酶原时间(PT)值,探讨心脏瓣膜置换术后的患者经动脉测压管和中心静脉留置管采血测定PT的可行性。方法选择心脏病瓣膜置换术后患者45例,术后第2天分别同时经外周静脉、动脉测压管和中心静脉留置管采血,分析三者统计学有无差异。结果 3种不同采血途径测定PT差异无统计学意义。结论临床工作中,可经动脉测压管和中心静脉留置管采血测定PT,新的采血途径既可减轻患者的痛苦和损伤,又可提高护理工作效率,提高患者的满意度。

Objective To study the feasibility of prothrombin time（PT） value which blood samples were taken from the peripheral veins,arteries and central venous in patients with heart valve replacement.Methods In 45 heart valve replaced patients,PT blood samples were take from the peripheral veins,arteries and central venous and analyzed to evaluate the difference among them in the second operative day.Results The difference of PT values gotten from three ways was not significant.Conclusion It was possible to get PT value from the way of arteries and central venous,which can reduce the pain and injury to patients and improve the nursing efficiency.
