预充式导管冲洗器在静脉留置针封管中的应用

目的探讨预充式导管冲洗器在心血管疾病病人静脉留置针封管中的应用效果。方法按入院时间先后次序,将225例使用静脉留置针的心血管疾病病人分为观察组116例,采用预充式导管冲洗器进行封管;将109例病人设为对照组,使用50 U/mL稀释肝素钠生理盐水封管,观察两组留置针导管回血堵塞、静脉炎、导管相关性感染的发生情况及留置针留置时间与护士封管所用时间。结果观察组病人留置针导管回血堵塞、静脉炎、导管相关性感染的发生率低于对照组;留置针留置时间长于对照组;护士封管所用时间少于对照组,差异均有统计学意义(P0.05)。结论采用预充式导管冲洗器对心血管疾病病人静脉留置针进行封管,可降低并发症的发生,提高护士工作效率。

Application of pre-filled catheter flushing device in the sealing of venous indwelling needle

Objective To explore the effect of pre-filled catheter flushing device on the sealing of venous indwelling needle.Methods One hundred and sixteen patients with venous indwelling needle were assigned into observation group, in which pre-filled catheter flushing device was used to seal the needle tube and another 109 with venous indwelling needle as control group, in which the needle tube was sealed with 50U/mL heparin saline.The two groups were compared in terms of blockage of the tube, phlebitis, catheter-associated infection,indwelling time of the needle and time for nurses to seal it.Results The rates of blockage of catheter, phlebitis and catheter-associated infection of the observation group were all lower than those of the control group.The indwelling time of the needle was significantly longer than that in the control group.The time for nurses to seal the catheter was significantly shorter than that in the control group（ all P〈0.05）.Conclusion Pre-filled catheter flushing device can reduce complication rate and improve working efficiency of nurses.
