INTRODUCTION Sepsis is defined as an infection associated with systemic manifestations of inflammation, which has become the most common complication in the perioperative period caused by severe burn/trauma and major surgical operation.[1,2] The incidence of sepsis in adults is estimated to be 149–240/100 000 per year, and that of severe sepsis and septic shock is 56–91/100 000 per year. In the last decade, the short-term mortality of sepsis has declined to around 20% in developed countries partly due to the international Surviving Sepsis Campaign （SSC）, while the mortality remains very high （50%–80%） in 1–5 years after discharge from hospitals.[3–7] Thus, sepsis and its subsequent severe sepsis and septic shock are currently major issues in the field of medical and health care.
