[Further discussion on postburn "shock heart " and its clinical significance].
A series of studies demonstrated that myocardial damage and cardiac dysfunction occur immediately after severe burn even before the intervention of significant reduction in blood volume as a result of increased capillary permeability. Because the heart is the power organ of the circulation, such myocardial damage and cardiac dysfunction lead not only to cardiac deficiency, it is also a precipitating factor of burn shock and ischemic/hypoxic injury. Therefore, we nominate this phenomenon as "shock heart". New measures including "volume replacement" plus "dynamic support" proposed according to this new recognition is of important clinical significance for burn shock resuscitation and prevention and treatment of ischemic/hypoxic injury, as well as reducing organ complications resulting from insufficient or excessive fluid resuscitation during early postburn stage.
