ICU injured patients often experience a condition of tissue hypoperfusion due to low cardiac output and oxygen delivery (DO2). The imbalance between oxygen demand and DO2 could be responsible for an anaerobic metabolism that is correlated with poor outcome. Several authors demonstrated that traditional (that is, serum lactate, base deficit) and oxygen-derived and carbon dioxide-derived parameters of anaerobiosis are helpful indicators of bad outcome in trauma patients. We aimed to identify predictors of morbidity in our ICU trauma patients.
Data for 175 adult trauma patients (age mean 50 ± 18.5 years) admitted to our ICU were prospectively collected from May 2006 and April 2007. Seventy hemodynamic, ventilatory, and metabolic parameters were evaluated within 3 hours after ICU admission. Accordingly to the GIVITI (Italian Group for the Evaluation of Interventions in ICU) database definitions, complications were defined as one or more organ dysfunctions or failures occurring during the ICU stay. Multivariate and receiver operating characteristic (ROC) curve analyses were applied.

1.01 - 2.1
This study demonstrated that the DO2/VCO2 ratio correlated well with morbidity. This ratio represents the imbalance between oxygen demand and delivery. The ratio might be continuously monitored in critically ill patients to assess an anaerobiosis state. This ratio together with the SAPS II ratio could predict complications in trauma patients.
