Main characteristics of patients with septic shock at ICU admission.

ICU: intensive care unit. SAPS II: simplified acute physiology score II (referred to the first 24 h from admission). SOFA: sepsis-related organ failure assessment (referred to the first 24 h from admission). Norepinephrine equivalent dose was calculated as norepinephrine (µg/min)+[dopamine (µg/kg/min)÷2]+epinephrine (µg/min)+[phenylephrine (µg/min)÷10] [41]. Central venous oxymetry was monitored in twenty-five patients; mixed venous oxymetry was monitored in five patients. Please note that most of the patients were firstly resuscitated in the Emergency Department and then transferred to the ICU.

ICU：即重症监护病房（intensive care unit）。SAPS II：简化急性生理学评分II（simplified acute physiology score II），评估时段为患者入院后最初24小时。SOFA：脓毒症相关器官功能衰竭评估（sepsis-related organ failure assessment），评估时段为患者入院后最初24小时。去甲肾上腺素等效剂量计算公式为：去甲肾上腺素（µg/min）+[多巴胺（µg/kg/min）÷2]+肾上腺素（µg/min）+[去氧肾上腺素（µg/min）÷10] [41]。25例患者接受中心静脉血氧饱和度监测，5例患者接受混合静脉血氧饱和度监测。请注意，绝大多数患者首先在急诊科接受复苏治疗，随后转入ICU。
