静脉留置针接真空采血器在内科急危重患者的应用

Application of venous indwelling needle connected with vacuum intravenous hemostix for acute and critically ill patients in internal medicine

目的探讨通过静脉留置针接采血器为急危重患者抽血，以及建立静脉通道，对穿刺成功率、完成时间及病人满意度的影响。方法将2008年5月-2010年9月我科收治的危重病人220例随机分成两组，观察组采用行外周浅静脉留置针穿刺，同时接真空采血器抽血化验、输液，对照组按常规分别行外周静脉输液及真空采血器抽血化验。观察2组在完成时间、患者满意度、穿刺成功率进行对比。结果观察组穿刺成功率为93．9％，完成时间（65±12）S，病人满意度97．3％。对照组穿刺成功率为85．7％，完成时间（88±15）S，病人满意度90．4％。观察组只进行一次静脉穿刺，时间快，既可输液又同时采血。结论采用静脉留置针接真空采血器穿刺一次就可以解决抽血输液的问题，不会影响到标本所需的血量及质量，同时缩短了完成时间，减轻病人痛苦，提高病人满意度。

Objective To probe into the influence of exsanguination and establishment of intravenous access upon puncture success rate, completion time and the satisfaction of the patients through the venous indwelling needle connected with vvaeuum intravenous hemostix for acute and critically ill patients. Methods The 220 critically ill patients admitted to our department were randomly divided into two groups during the May 2008 to September 2010, the observation group adopts venous indwelling needle connected with vacuum intravenous hemostix to take blood tests and transfusion, the control group was performed intravenous infusion by routinely and blood tests by vacuum intravenous hemostix ,and to observe the eomparation of completion time, patient satisfaetion, the success rate of puncture, in 2 groups. Results The puncture success rate of the observation group was 93.9%,completion time was （ 65 ± 12 ） s, 97.3% patient was satisfactory.The puncture success rate of the control group was 85.7%,the eompletion time was （ 88± 15 ）s, 90.4% patient was satisfactory. The observation group with venipuncture and exsanguination at the same time was faster.Conclusion The venous indwelling needle connected with vacuum intravenous hemastix can solve the problem, will not affect the amount of blood required and the quality of specimens , while reducing the completion time and patient＇ s suffering, improving patient＇ s satisfaction.
