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 experimental 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 significant (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＜0.05).Abnormal events occurred 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.
