Shaking stress aggravates burn-induced cardiovascular and renal disturbances in a rabbit model.
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. Cardiovascular hemodynamics and functional and pathological changes of the heart and kidney were examined. Compared to normal controls, untreated burned animals showed decreased hemodynamic parameters, increased serum lactic acid, and severe myocardial inflammation. The burn-induced hemodynamic abnormalities and cardiac injury were aggravated by shaking stress. Burn injury led to reduced urine volume, elevated serum creatinine and blood urea nitrogen, and formation of erythrocyte casts in renal tubules. Shaking stimulation worsened the burn-associated functional and pathological changes of the kidney. 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.
