改良静脉留置针封管方法在心血管疾病患者中的应用效果研究

Research on the Effect of an Improved Sealing Method of Venous Indwelling Needle in Cardiovascular Patients

目的探讨改良静脉留置针封管方法在心血管疾病患者中的应用效果。方法将240例心内科使用静脉留置针患者随机分为对照组120例和实验组120例。对照组患者采用常规封管方法进行封管操作,实验组患者在常规方法的基础上进行改良操作。比较两组患者静脉留置针回血率、堵管率、留置针留置时间。结果实验组封管效果明显优于对照组,实验组静脉留置针回血、堵管发生率显著低于对照组(P﹤0.01),留置时间长于对照组(P﹤0.05),差异有统计学意义。结论对心血管疾病患者进行静脉留置针封管方法的改良,能最大限度地发挥静脉留置针持续留置的优点,有效降低回血和堵管的发生,减轻心血管疾病患者的身心痛苦。

Objective To explore the effect of an improved sealing method of venous indwelling needle in cardiovascular patients. Methods 240 patients who were using venous indwelling needle were separated into treatment and control group randomly. Normal sealing method was used in control group while an improved method was used in treatment group. Blood flow from venous, obstruction rate and catheter life-time were observed respectively. Results The rate of Blood flow from venous and obstruction in treatment group were lower than control group（P〈0.01）, and the catheter life-time of treatment group was longer than control group（P〈0.05）. Conclusion The improves sealing method can reduce the blood flow from venous and obstruction.
