La saturación venosa central de oxígeno es un factor predictor de mortalidad en el paciente con choque séptico

Objective: to determine the central venous saturation of abnormal initial oxygen (SvCO2) (high or low) as a predictor of mortality in patients with septic shock admitted to the emergency area of Carlos Andrade Marín Hospital.Design and location: this is an analytical, observational, prospective study on a cohort of patients admitted to the critical area of emergency of this health unit. Subjects: 107 patients admitted in the months of June to September 2015, with a mortality follow-up of 28-day.Measurements and results: initial SvcO2 was measured by central venous catheter at the time of shock diagnosis. Mortality at 28 days was 46.2%. Only APACHE II values (OR 1.11, CI 1.04-1.19 p = <0.01) andmechanical ventilation (OR 0.19, CI 0.05-0.62, p = 0.01) had significant statistical value in the logistic regression. APACHE II was the most important single factor, in the CART model arterial pH and procalcitonin were useful.Conclusion: Central venous saturation of abnormal or high initial O2 (SvcO2) was not found to be useful in predicting mortality at 28 days of follow-up. Measurement of SvcO2 is a simple method that indirectly reflects tissue oxygenation. The APACHE II is an independent predictor of mortality at 28 days and the use of mechanical ventilation had an inverse relationship with mortality.
