摘要:

背景:压疮或压力溃疡是临床医学的疑难综合并发症,虽然防压疮材料及治愈压疮的药物很多,但是这些只能治标不治本,探究合理的人体压力分布对预防压疮就显得意义非凡。
目的:改变仰卧姿势,实现不同人体压力分布,进而研究人体压力分布与仰卧姿势之间关系,探寻较为合理的人体压力分布。
方法:对于不同床垫气压下不同仰卧姿势利用XSENSOR压力分布测试及分析系统进行体压指标的测量,通过EXCEL、MATLAB软件对实验数据汇整与分析,进而对不同仰卧姿势之间人体压力分布指标进行对比分析,并利用SPSS16.0统计分析软件对彼此体压指标之间进行t检验。
结果与结论:不同仰卧姿势下彼此之间人体压力分布指标的t检验概率P 均小于0.05,说明改变人体仰卧姿势对人体压力分布有重要影响。结果显示大腿抬高10°并且背部抬高0°时人体压力分布比较合理,而且全身的最大压力、足跟部的最大压力也最小,是较为理想的人体压力分布。

Abstract:

BACKGROUND: Pressure sore or pressure ulcer is a comprehensive complication in clinic. Although there are many anti-pressure ulcer materials and drugs, their effects are temporary rather than permanent. Therefore, to explore the human body pressure distribution reasonable to prevent pressure ulcer is of great consequence.
OBJECTIVE: Through changing supine positions, to realize the different human body pressure distribution, and then to study the relationship between human body pressure distribution and supine positions so as to explore more reasonable pressure distribution in the human body.
METHODS: Human body pressure distribution indexes were measured at different supine positions under the different air pressure of the mattress by using the pressure distribution measurement and analysis of the XSENSOR system. Then, the experimental data were collected and tidied through Excel and MATLAB software to compare and analyze the human body pressure distribution indexes under different supine positions using SPSS 16.0 statistical analysis software. t-test was done for pairwise comparisons of body pressure indexes.
RESULTS AND CONCLUSION: P values for human body pressure distribution indexes under different supine positions were less than 0.05, indicating that changing supine positions exerts an important influence to human body pressure distribution. When the angle of the leg elevation-the back elevation was 10º-0º, the human body pressure distribution was more reasonable resulting in the biggest pressure of the whole body and the least heel pressure, which is the ideal human body pressure distribution.
