Tissue temperature, flux and oxygen of sacral and trochanteric area under pressure of healthy subjects: A quasi-experimental study.

Aim: 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.

Methods: 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).

Pressure levels in the trochanter area according to repositioning at different degrees of inclination in healthy subjects.

Objectives: 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.
