ABSTRACT

Introduction: ΔCO2 has been used as tissular perfusion parameter in the postoperative period of cardiovascular surgery.
Objectives: To evaluate ΔCO2 as tissue perfusion parameter in patients with septic shock as well as it’s utility in predicting mortality.
Methods: Prospective observational study from March 2009 to March 2010.
Results: 46 patients with septic shock were included and divided in one of two groups: high ΔCO2 (n = 11) and low ΔCO2 (n = 35). Demographics as well as reanimation parameters and optimization of goals in both groups were similar. Mortality was higher in high ΔCO2 group vs low ΔCO2 group: 34% vs 2.8% respectively.
Conclusion: ΔCO2 higher than 6 mmHg is an adequate parameter for the evaluation of tissular perfusion in septic shock patients. ΔCO2 higher than 6 mmHg and that does not lowers after reanimation predicts a bad prognosis in septic patients.
