Effect of Ischemia and Reperfusion on Skeletal Muscle Damage Available to Purchase

Sustained mechanical loading of soft tissues covering bony prominences, as experienced by bedridden and wheelchair-bound individuals, may cause skeletal muscle damage. This can result in a condition termed pressure-related deep tissue injury (DTI), a severe kind of pressure ulcer that initiates in deep tissue layers, and progresses towards the skin. Damage pathways leading to DTI can involve ischemia, ischemia/reperfusion injury, impaired lymphatic drainage, and sustained tissue deformation. Recently, we have provided evidence that in a controlled animal model, deformation is the main trigger for damage within a 2h loading period [1,2]. However, ischemia and reperfusion may play a more important role in the damage process during prolonged loading periods.
