Cardiac stress is a critical determinant of outcomes associated with severe thermal injury. The cardiovascular response to a catecholamine-mediated surge from severe burns passes through two phases. Initial hypovolemia with myocardial depression leads to a low cardiac output, which then progresses to a hyperdynamic-hypermetabolic phase with increased cardiac output.
心脏应激是严重热损伤相关预后的关键决定因素。严重烧伤引起的儿茶酚胺介导的激增所引发的心血管反应经历两个阶段。最初的低血容量伴心肌抑制导致心输出量降低,随后发展为心输出量增加的高动力-高代谢阶段。
