To evaluate the changes that take place in the perfusion, oxygenation and local temperature of the skin of the sacrum and trochanter when subjected to direct pressure for 2 h.
Quasi-experimental study in the preclinical phase with healthy subjects acting as their own controls (intrasubject control). The outcome variables were measured with a laser Doppler system (local temperature and oxygenation) and by near-infrared spectroscopy (perfusion). The pressure exerted was measured with a capacitive pressure sensor. No more than one week elapsed between the sacrum and trochanter measurements.
The study sample consisted of 18 persons. The comparative analysis of the fluctuations in the parameters measured on the skin of the trochanters and sacrum, according to the time elapsed, revealed a statistically significant increase in temperature and in the pressure exerted. On the other hand, the changes in capillary blood flow and in SaO2 were not statistically significant.
Our study results show that changes found in terms of temperature and pressure should be taking into account when planning personalised repositioning to patients according to biomechanical and biological situations that vary between anatomical areas. In future research, the changes reported could be evaluated in patients with risk factors for the development of pressure ulcers, thus facilitating the introduction of more personalised planning in the care and prevention of these injuries.
评估骶骨和大转子皮肤在受到2小时直接压力时灌注、氧合和局部温度的变化。
临床前阶段的准实验研究，以健康受试者作为自身对照（受试者内对照）。通过激光多普勒系统（局部温度和氧合）和近红外光谱法（灌注）测量结果变量。用电容式压力传感器测量施加的压力。骶骨和大转子测量之间间隔不超过一周。
研究样本包括18人。根据经过的时间，对大转子和骶骨皮肤测量参数波动的比较分析显示，温度和施加的压力有统计学意义的增加。另一方面，毛细血管血流量和血氧饱和度的变化无统计学意义。
我们的研究结果表明，在根据解剖区域之间不同的生物力学和生物学情况为患者规划个性化翻身时，应考虑到温度和压力方面的变化。在未来的研究中，可以在有发生压疮风险因素的患者中评估所报告的变化，从而有助于在这些损伤的护理和预防中引入更个性化的规划。
