The Relationship

Introduction: Studies have shown that there is a complex relationship between lactate and ScvO2. Methods: A retrospective study was carried out in 37 intensive care patients with sepsis or septic shock. The relationship between lactate and ScvO2 was explored with correlation analysis and simple linear modelling. Results: Lactate and ScvO2 were significantly correlated in patients with septic shock (r2 = 0.46, p = 0.001; y = -4.11x+ 82.62), but not in sepsis. y Significant correlation between these parameters was also found in the group of patients who went on to die (r2 = 0.67, p < 0.01; y = -3.70x + 78.61), but not in patients who survived. Conclusions: In sepsis, the correlation between ScvO2 and lactate is not constant over the sepsis course and may be dynamic. In the resuscitation of sepsis and/or septic shock, changes in ScvO2 requires further study.

Lactate Levels

The initial lactate level has been used as one of mortality predictors in patients with septic shock. Different studies measured the concentrations of blood lactate obtained from different vessels. Even in some retrospective studies, blood lactate levels from heterogeneous sources (artery, central vein, and peripheral vein) have been used. Practicing physicians face following questions: what data have the best predictive value, can they replace each other? In our observations, а high positive linear correlation was found between lactate concentrations in arterial and central venous blood (R = 0.895; P < 0.001). Both indicators have satisfactory values for predicting treatment outcome. Lactate level in arterial blood had a slightly better predictive value compared to its concentration in central venous blood.

Catheter Tip

Fifty-three central venous catheters were followed up by radiography or direct observation during open-heart surgery. Forty of these were satisfactorily positioned for recording central venous pressure or for sampling central venous blood. Radiography showed that the catheter tip was in an unsatisfactory position in 21 per cent of cases. It is recommended that radiographic confirmation of the site of the catheter tip be obtained as a routine and if necessary the catheter can be re-positioned and another radiograph taken.
