摘要
目的探讨输液器直接快速输入封管法、生理盐水注射液封管法和肝素稀释注射液封管法对静脉留置针留置时间的影响。方法将200例患者根据入院时间分为快速输入封管组(82例)、生理盐水封管组(59例)及肝素液封管组(59例),分别进行静脉留置针封管,并记录留置时间,采用方差分析及Cox多因素模型,分析静脉留置针留置时间的影响因素及不同封管法留置时间的差异。结果(1)输液器直接快速输入封管法、生理盐水注射液封管法和肝素稀释注射液封管法的静脉留置针留置时间差异有统计学意义(F=6.92,P=0.0012),其中肝素稀释注射液封管法的静脉留置针留置时间少于其他两种方法(P均<0.05);(2)封管方法(X8)与留置时间显著相关(RR=1.222),影响静脉针留置时间多因素分析的Cox回归方程为h(t,x)=h_0(t)exp^(0.20063×X8)。结论封管方法是影响留置时间的独立因子,以输液器直接快速输入和生理盐水注射液封管法的静脉留置针留置时间较长。
Objective To investigate the difference and influential factors of maintaining time of Peripherally Inserted Central Catheter （PICC） with various sealing methods, pressured injecta,normal sodium and heparin diluted solution. Methods Two hundred patients with PICC were divided into three groups according to admission time. Group A（ n =82） was sealed with pressured injecta. Group B（ n =59） was sealed with normal sodium. Group C （ n =59） was sealed with heparin diluted solution. The maintaining time of PICC was recorded. Influential factors were analyzed and compared by variance analysis, t-test and Cox multiple regression model. Results There was significant difference in PICC maintaining time among the three groups（ F =6. 92, P =0. 0012）. The maintaining time of Group C was significantly less than that of Group A and Group B（ t = 2.64, P =0. 0093; t =3.91, P =0. 0002）. Cox multiple regression analysis showed that there was significant correlation between PICC maintaining time and sealing method （X8） （ RR = 1. 222）, with the Cox regression equation of h（t,x） =h0（t）exp^0.20063×X8. Conclusion The sealing method is a significant factor influencing PICC maintaining time. The PICC can be maintained longer when it is sealed with pressured injecta or normal sodium.
