Study Description

Brief Summary:

The purpose of this study is to compare lactate clearance in patients with severe sepsis and septic shock according to the presence of hepatic dysfunction.

Condition or disease
Sepsis Liver Failure

Detailed Description:

Lactate clearance is well known to be associated with mortality in patients with severe sepsis and septic shock. To normalize lactate levels is one of important goals of early resuscitation of sepsis patients.

Lactate clearance can be changed by various factors including patient characteristics, severity of shock, and treatment. In particular, hepatic dysfunction might impair the clearance of lactate because liver is a principal organ for lactate metabolism. However, an association between lactate clearance and hepatic failure has not been evaluated during initial resuscitation of patients with severe sepsis and septic shock. The primary goal of this study is to compare lactate clearance in patients with severe sepsis and septic shock according to the presence of hepatic dysfunction. The secondary goal is to evaluate if lactate clearance is associated with mortality even in patients with hepatic dysfunction.
