ClinConnect Summary

Sepsis remains a great challenge for clinicians, early goal-directed therapy(EGDT), referring to a number of target-achieving indicators including systemic central venous oxygen saturation(ScvO2) after initial fluid resuscitation within 6 hours, has been one of the main treatment for sepsis. ScvO2 is the only indicator that reflects tissue oxygen metabolism. However, there're studies confirmed that ScvO2 oriented EGDT cannot reduce the mortality of sepsis. So it is important to find out a more effective indicator. Lactic acid is a product of anaerobic metabolism of the body, lactate clearan...
