便携式手臂托架的设计及其在PICC置管中的应用

Designing of a portable arm bracket and its application in PICC placement

目的验证便携式手臂托架在PICC置管中应用的效果。方法选取2016年8月—11月PICC置管患者98例作为实验组,使用便携式手臂托架进行PICC置管;2016年4月—7月PICC置管患者82例作为对照组,使用简易木板进行PICC置管,评价两组置管时的舒适度、置管成功率、多次进针和送导丝例数、并发症发生情况。结果实验组1级舒适度高于对照组,实验组2、3、4级舒适度均低于对照组,差异有统计学意义(P<0.001)。实验组的置管成功率(98.0%)高于对照组(93.9%),但差异无统计学意义(P=0.31)。实验组多次进针和送导丝的例数比对照组少,差异有统计学意义(P<0.05)。实验组3例(3.1%)出现并发症,对照组6例(7.3%)出现并发症。结论便携式手臂托架的托举和抬高功能提高了置管舒适度和置管成功率,减少并发症发生。

Objective To design and apply a portable arm bracket for patients undergoing PICC placement and to solve the problem of raising and placing the arm during PICC placemen and promote comfort level. Methods Ninety-eight patients were provided with portable arm bracket between August and November in 2016 as the ex- perimental group,82 patients were provided with wood board between April and July in 2016 as the control group. The comfort degree,placement success rate,number of multiple attempts to insert needle and advance guidewire,and case of abnormal events were compared between two groups. Results Level 1 comfort in the experimental group was higher than the control group,and level 2,3 and 4 comfort in the experimental group were lower than the control group,and differences were statistically significant （P〈0.001）. Placement success rate of the experimental group（98.0%） was slightly higher than that of the control group（93.9%）,but the difference was not statistical sig- nificant （P=0.31）. The number of multiple attempts to insert needle and advance guidewire in the experimental group was lower than the control group,and the difference was statistically significant（P〈O.05）. Abnormal events oc- curred in 3 cases in the experimental group and the incidence rate was 3.1%;there were 6 cases in the control group and the incidence rate was 7.3%. Conclusion The shelve and raising function of the portable arm bracket boost patients＇ catheter comfort degree,improve the success rate of catheterization and reduce the occurrence of complications cases,
