Online oxygen measurements in ex vivo perfused muscle tissue in a porcine model using dynamic quenching methods

摘要

Introduction Transplantation of autologous free tissue flaps is the best applicable technique for treating large and complex tissue defects and still has one major failure criterion. Tissue—and in particular muscle tissue—is strongly sensitive to ischemia, thus after a critical period of oxygen depletion the risk of a partial or total flap loss is high.
