Patient repositioning is a recommended intervention to prevent or treat pressure ulcers (PUs). One option under consideration is the tailored repositioning according to patient characteristics, but more knowledge is needed on how different repositioning patterns influence on skin pressure. To determine what degree of inclination of the body in bed generates more pressure in the trochanteric region. Additionally, to analyze the influence of factors such as gender, age and anthropometric characteristics in the variations of this pressure.
Analytical cross-sectional study. Body Mass Index (BMI), lean mass and fat mass were measured in healthy volunteers subject to different inclinations (90°, 60° and 30°) in right lateral decubitus. Pressure was measured with a capacitive surface.
In total, 146 subjects were included, of which 45 were men and 101 women. The results showed pressure differences due to the inclination according to gender and anthropometric values, being statistically significant in men at 90° and 60°, and in women at 30°. (hombres 90° p = 0,026, 60° p = 0,049; mujeres 30° p = 0,036) según prueba Brown-Forsythe.
There are differences in the pressures of the trochanteric zone depending on anthropometric factors and by gender, in different body positions. Obese people exerted a higher pressure in the trochanter area at 30° of body inclination than overweight, normal weight and underweight people, respectively. From the clinical point of view, these findings invite to consider a possible differentiation in the repositioning interventions of the patients, according to gender and BMI, as a preventive strategy for PUs.
患者体位变换是预防或治疗压疮（PU）的推荐干预措施。正在考虑的一种选择是根据患者特征进行定制的体位变换，但需要更多关于不同体位变换模式如何影响皮肤压力的知识。本研究旨在确定身体在床面上倾斜多大角度会在股骨粗隆区产生更大的压力。此外，还分析了性别、年龄和人体测量特征等因素对这种压力变化的影响。
横断面分析研究。对健康志愿者进行不同侧卧位（90°、60°和 30°）倾斜角度下的体质量指数（BMI）、瘦体重和脂肪量测量。使用电容式表面测量压力。
共纳入 146 名受试者，其中 45 名男性，101 名女性。结果显示，根据性别和人体测量值，倾斜角度会导致压力差异，男性在 90°和 60°时以及女性在 30°时差异具有统计学意义（男性 90°p=0.026，60°p=0.049；女性 30°p=0.036）。
在不同的体位下，根据人体测量因素和性别，股骨粗隆区的压力存在差异。肥胖者在身体倾斜 30°时，股骨粗隆区的压力比超重、正常体重和体重不足者分别高。从临床角度来看，这些发现提示我们，可能需要根据性别和 BMI 考虑对患者进行体位变换干预的差异化，作为预防 PU 的策略。
