Abstract:
Objective:To investigate the application effect of rapid leg circumference positioning measuring device in critical ill patients.Methods:From August 2021 to November 2021, selected 50 patients in ICU of Hangzhou First People′s Hospital. Two methods to measure the leg circumference of the same patient at the same time were used. The traditional method used a tape measure to measure the leg circumference, while the improved method used the rapid positioning and measuring device of leg circumference to measure the leg circumference. the average total positioning time, average total measurement time, average measurement difference and nurses′ satisfaction were compared.Results:The total positioning time and total measurement time of the improved method were respectively (15.2 ± 3.3) s and (34.0 ± 3.9) s, which were shorter than the traditional method (29.0 ± 3.1) s, (79.1 ± 4.9) s, the differences were statistically significant ( t=50.93, 21.43, P<0.05). The measured data difference between 15 cm above patella and 10 cm below patella of the improved method was (1.27 ± 0.67) mm, (0.93 ± 0.31) mm, which were less than the traditional method (8.82 ± 3.28) mm and (7.94 ± 2.11) mm, the differences were statistically significant ( t=28.66, 23.42, P<0.05). Nurses′satisfaction in the improved method was 96.0% (48/50), which was higher than 36% (18/50) in the traditional method, and the difference was statistically significant ( Z=5.78, P<0.05). Conclusions:The leg circumference measurement device designed in this study can effectively save the leg circumference measurement time, quickly and accurately, increase the comfort of patients and improve the satisfaction of patients and nursing staff. It is worthy of clinical application.
