An interoperable, flexibly staffed, and rapidly expandable TCC network must be further developed given the potential for large casualty volumes to overwhelm a single TCC provider with multiple duties. Lessons learned from development of this capability should have applicability for managing military and civilian mass casualty events. Ex vivo normothermic limb perfusion (EVNLP) provides several advantages for the preservation of limbs following amputation the ability to maintain oxygenation and temperature of the limb close to physiological values, a perfusion solution providing all necessary nutrients at optimal concentrations, and the ability to maintain physiological pH and electrolytes. However, EVNLP cannot preserve the organ viability infinitely. We identified evidence of mitochondrial injury (swelling, elongation, and membrane disruption) after 24 hours of EVNLP of human upper extremities. The goal of this study was to identify metabolic derangements in the skeletal muscle during EVNLP. Fourteen human upper extremities were procured from organ donors after family consent. Seven limbs underwent EVNLP for an average of 41.6 ± 9.4 hours, and seven contralateral limbs were preserved at 4°C for the same amount of time. Muscle biopsies were performed at 24 hours of perfusion, both from the EVNLP and control limbs. Perturbations in theic derangement toward the end of perfusion, which correlated with detection of altered mitochondrial structure, swelling, and elongation. Early and adequate administration of enteral nutrition (EN) improves outcomes in critical care patients. However, the environment where Critical Care Air Transport teams provide patient care poses particular challenges to achieving the same standard of nutritional support readily administered in civilian intensive care units.
