The aim of this study was to propose a lateral oscillating device for the prevention of pressure ulcers by understanding the mechanisms of tissue protection in healthy individuals during prolonged decubitus. We also sought to determine the optimal time interval for oscillation, considering peak pressure peaks and tolerable pressure limits as a function of individual characteristics such as age, weight, height, gender, and BMI.
A quasi-experimental, descriptive and analytical observational study was conducted between January 2022 and June 2023 with a sample of 25 healthy volunteers. Sacral, heel and trochanter pressure measurements were performed using sensors. Descriptive and bivariate statistical analyses were applied, and a linear regression model was used to analyze the relationship between independent variables and peak pressures recorded.
Peak pressure at the trochanter was significantly associated with age, weight and gender, while pressure at the sacrum showed a relationship only with gender. No significant associations were found for other variables. The 80th percentile was used to determine the maximum tolerable pressure, and the independent variables collectively explained 60% of the variance in maximum trochanter pressure (R = 0.60; p = 0.0006). These findings helped to establish optimal time intervals for lateral oscillation, tailored to individual variability.
The designed lateral oscillating device proved to be effective in promoting tissue perfusion and reducing pressure build-up, thus contributing to pressure ulcer prevention. This personalized approach could significantly improve the care of immobilized patients in clinical settings.
本研究的目的是通过了解健康个体在长期卧位期间的组织保护机制，提出一种用于预防压疮的侧向振荡装置。我们还试图确定振荡的最佳时间间隔，将峰值压力峰值和可耐受压力极限视为年龄、体重、身高、性别和BMI等个体特征的函数。
在2022年1月至2023年6月期间，对25名健康志愿者进行了一项准实验性、描述性和分析性观察研究。使用传感器进行骶骨、足跟和大转子压力测量。应用描述性和双变量统计分析，并使用线性回归模型分析自变量与记录的峰值压力之间的关系。
大转子处的峰值压力与年龄、体重和性别显著相关，而骶骨处的压力仅与性别有关。未发现其他变量有显著关联。第80百分位数用于确定最大可耐受压力，自变量共同解释了最大大转子压力方差的60%（R = 0.60；p = 0.0006）。这些发现有助于确定根据个体差异量身定制的侧向振荡最佳时间间隔。
设计的侧向振荡装置被证明在促进组织灌注和减少压力积聚方面有效，从而有助于预防压疮。这种个性化方法可以显著改善临床环境中固定患者的护理。
