双向双固定器U型固定法在静脉留置针中的应用

Application of the two-paths double U-shaped fixer in the intravenous indwelling needle

目的：将设计的双向双固定器应用于临床静脉留置针固定的研究。方法选择2015年1－6月使用静脉留置针患者420例按照随机数字表法进行随机分组，试验组使用双向双固定器U型固定210例，对照组使用胶布Y型固定210例，观察比较2组留置针在留置期间导管内回血、导管堵塞、静脉炎、导管滑脱等现象的发生率变化，以及舒适度情况的比较。结果试验组导管内回血、导管堵塞、导管滑脱发生率分别为6.2%（13/210）、0.5%（1/210）、0，均低于对照组的48.6%（102/210）、5.7%（12/210）、1.4%（3/210），差异有统计学意义（χ2=117.895，P＜0.01）。试验组静脉炎Ⅰ、Ⅱ、Ⅲ、Ⅳ级发生率分别为3.3%（7/210）、1.4%（3/210）、0.9%(2/210)、0，均低于对照组的11.9%（25/210）、9.0%（19/210）、3.8%（8/210）、2.4%（5/210）,差异有统计学意义（Z=-5.960，P＜0.01）。试验组1、2、3、4级舒适度分别为92.4%（194/210）、6.2%（13/210）、1.4%（3/210）、0，均优于对照组的36.7%（77/210）、46.7%（98/210）、12.4%（26/210）、4.3%（9/210），差异有统计学意义（Z=-16.228，P＜0.01）。结论 U型双向双固定法优于Y型胶布固定法，双向双固定器作为一种新型固定器能替代传统的静脉留置针固定方法，有效地保护留置针使用的安全，同时具有方便使用、方便观察、美观的优势，可以在临床推广使用。

Objective To study the application of the two-paths double U-shaped fixer in clinical intravenous indwelling needle fixation. Methods A total of 420 cases using of intravenous indwelling needle from January to June 2015 were involved and divided into experimental group(210 cases) and control group(210 cases) by random digits table method. The two-paths double U-shaped fixer was applied in experimental group and the control group were used tape by Y type to fix. The incidence of returning-blood, blocking, phlebitis, slippage and the comfort between two groups were observed and compared. Results The incidence of returning-blood, blocking, phlebitis, slippage in experimental group were 6.2%(13/210), 0.5%(1/210), 0 , which were lower than those in control group 48.6%(102/210), 5.7%(12/210), 1.4%(3/210) seperately, the differences were statistically significant (χ2=117.895, P<0.01). The incidence of phlebitis levelⅠ,Ⅱ,ⅢandⅣin experimental group were 3.3%(7/210), 1.4%(3/210), 0.9%(2/210), 0, which were lower than those in control group 11.9%(25/210), 9.0%(19/210), 3.8%(8/210), 2.4%(5/210), the differences were statistically significant(Z=-5.960, P<0.01). The incidence of the comfort level 1, 2, 3 and 4 in experimental group were 92.4%(194/210), 6.2%(13/210), 1.4%(3/210), 0 individually, which were higher than those in control group 36.7%(77/210), 46.7%(98/210), 12.4%(26/210), 4.3%(9/210), the differences were statistical significant (Z=-16.228, P < 0.01). Conclusions Two-paths double U-shaped fixationis is better than Y-shaped tape fixation. To compare the venous indwelling needle fixation, two-paths double U-shaped fixer could fix more effectively and safety. At the same time, it also has advantages in convenient, observation and appearance. It could be widely used in clinical practice.
