The aim of this study was to address the effects of shaking stress (a.k.a. physical agitation) on burn-induced remote organ injury and to evaluate the application of delayed fluid resuscitation to treat severe burns under shaking conditions. Healthy adult male rabbits, weighing 2.50±0.40 kg, were randomly assigned to the following groups: control group, burn group, and burn+shaking group. One half of burned animals received a 6-h delayed fluid resuscitation and the other half remained untreated. ⋯ Fluid resuscitation markedly mitigated cardiac and renal injury in burned animals, and, to a lesser extent, in the presence of shaking stimulation. Shaking stimulation aggravates burn-induced cardiovascular and renal disturbances. Delayed fluid resuscitation attenuates cardiac and renal damages in burn injury under shaking conditions.

Functional late outgrowth endothelial progenitors isolated from peripheral blood of burned patients.
Bioengineered skin substitutes are increasingly considered as a useful option for the treatment of full thickness burn injury. Their viability following grafting can be enhanced by seeding the skin substitute with late outgrowth endothelial progenitor cells (EPCs). However, it is not known whether autologous EPCs can be obtained from burned patients shortly after injury. ⋯ The present study supports that, in patients with burns of moderate extension, it is feasible to obtain functional autologous late outgrowth EPCs from peripheral blood. These results constitute a strong incentive to pursue approaches based on using autotransplantation of these cells to improve the therapy of full thickness burns.

Airway tissue shows unexpected invulnerability to heated air. The mechanisms of this phenomenon are open to debate. ⋯ Compared to the inhalational air hyperthermia, airway surface temperature was much lower, but was still positively correlated with thermal injury severity.
