大面积烧伤休克期血流动力学呈现内在的、持续动态的变化规律，由休克早期的“低排高阻”逐渐过渡到回吸收期的“高排低阻”，并具有明显的时间依赖性。血流动力学指标的正常值不是烧伤休克复苏的终点，追求休克期血流动力学的正常化将导致过度复苏。每小时尿量仍然是指导烧伤休克复苏的“金标准”。动态观察血流动力学指标的变化可以辅助临床治疗，在休克复苏不良、心肺肾等脏器功能损害和老年人、儿童等特殊人群具有更大的作用。“,”In shock stage of extensive burns, the hemodynamics shows inherent and continuously dynamic changes, which gradually transits from “ low output and high resistance” in early shock stage to “ high output and low resistance” in the stage of edema reabsorption, with significant time-dependence. Normal values of hemodynamic parameters are not the endpoint of resuscitation for burn shock. To pursue the normalization of hemodynamic in shock stage will lead to excessive resuscitation. Urine output per hour is still the “ gold standard” for burn shock resuscitation. Dynamic observation of hemodynamic variables can assist clinical treatment, and has more significant roles in refractory shock, cases combined with injuries of heart, lung or kidney, and special populations of the elderly and children.
