About

pre and post intervention quasi-experimental epidemiological study without a control group will be carried out in large burned patients that will evaluate the influence on metabolic expenditure of the inclusion of active external rewarming in the control of body temperature.

Full description

the heavily burned patient requires specific care to prevent hypothermia and maintain body temperature. You are at high risk of developing hypothermia in the acute phase due to heat losses from convection, radiation, evaporation, and conduction. After the acute phase, the patient due to physiological mechanisms and the hypermetabolic response mainly demands a temperature close to 38.5ºC, ruling out the infectious focus. According to the authors, environmental temperatures between 28-33ºC are recommended for the care of these patients to decrease energy expenditure. The research carried out has studied the influence of passive external heating (environmental regulation), without including the influence of active external heating (heat blankets, heating plate ...) or the study of the thermal comfort of large burned patients and of professionals who provide them they attend.

A pre and post intervention quasi-experimental epidemiological study without a control group will be carried out in large burned patients that will evaluate the influence on metabolic expenditure of the inclusion of active external rewarming in the control of body temperature. Metabolic expenditure will be measured by indirect calorimetry in the usual treatment with passive external rewarming and post-intervention in the combination of passive and active external heating. The combination of passive and active external reheating will previously study the operating temperature in various cases for optimal application, as well as the definition of thermal comfort in the large burn unit. The specific training of the personnel involved in the care of these patients will be required for the application of the evidence-based recommendations and the evaluation of their implementation.
