Abstract:
Lactate acid is an attractive biomarker reflecting microcirculatory dysfunction and tissue hypoxia.Surviving Sepsis Campaign in 2012 recommend lactate acid as one of the practical biomarkers representingtissue hypoxiato guide management of patients of septic shock.The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) in 2016 updated septic shock clinical criteria as a vasopressor requirement to maintain a mean arterial pressure of 65mmHg(1mmHg=0.133kPa) or greater and serum lactate acid level greater than 2mmol/L(>18mg/dl) in the absence of hypovolemia.Lactate acid ≥4mmol/L is often associated with poor clinical outcomes in septic shock patients.Lactate-guided therapy is becoming increasingly important in guiding the resuscitation and the use of vasoactive agents of septic shock.Lactate clearance and early lactate area are valuable indicators to predict the prognosis in patients with septic shock.
