不同封管间隔时间对中长导管血栓性堵管的影响

Effect of different tube sealing interval time on thrombosis plugging in middle-long catheter

目的探讨防止静脉留置针中长导管置管72 h内血栓性堵管的适宜封管间隔时间。方法将2011年8月至2012年2月收治的104例患者随机设为对照组49例,封管间隔时间12 h;改进组55例,封管间隔时间6 h,比较两组导管血栓性堵管次数和不同时间点的最大静脉滴注速度。结果对照组血栓性堵管25例次,改进组9例次;改进组最大静脉滴注速度优于对照组,两组血栓性堵管次数和最大静脉滴注速度比较,差异均有统计学意义(P<0.05)。结论预防中长导管置管72 h内血栓性堵管,封管间隔时间6 h优于12 h。

Objective To determine the suitable sealing interval time for preventing intraductal venous thrombosis plugging in indwelling venous needle with middle-long catheter within 72 h.Methods 104 patients treated from August 2011 to February 2012 were randomly divided into two groups,the control group（49 cases）with tube sealing interval time of 12 h and the improvement group（55 cases）with tube sealing interval time of 6 h.The frequency of intraductal venous thrombosis plugging and the maximum intravenous dripping speeds at different time points were compared between the two groups.Results Venous thrombosis plugging were 25 case-times in the control group,but 9 case-times in the improvement group.The improvement group was better than the control group in the maximum intravenous dripping speed.Comparing venous thrombosis plugging times and maximum intravenous dripping speed between the two groups showed statistical difference（P0.05）.Conclusion Tube sealing interval time of 6 h is better than 12 h in the prevention of intraductal venous thrombosis plugging in middle-long catheter indwelling within 72 h.
