Valoración de la glucemia sérica como marcador pronóstico en el paciente séptico crítico

glycemia is a infection risk factor, however, there are not enough evidences allowing its use as a prognostic marker of mortality in critical septic patients. study includes 206 patients admitted in a consecutive way in intensive therapy care (eight floor) of the "hermanos ameijeiras" clinical surgical hospital. severity was assessed according to the simplified acute physiology score scale (saps-3). the fasting daily value of glycemia was measured for the first 6 days of stay, the higher value during the 3 first days and the values difference between the third and the first day. the spearmen's correlation coefficient was applied for quantitative variables. the independent value of the variable was studied using several logistic regression forms. a statistic significance of p<0,05 was considered. there was association between saps-3 and the first day glycemia (p=0,01). glycemia among the living and death persons haven't significant differences. the higher value of glycemia of the first three days for survivors was of 8,41 (±3,25) mmol/l and 8,72 (±3,04) mmol/l for deceased. there weren't differences between the glycemia subtraction between the third and the first day among the leaving persons(-0,17 ±3,9 mmol/l) and those deceased (0,07±2,8 mmol/l) (p=0,66). it was impossible to demonstrate the usefulness of glycemia as a prognostic marker in relation to mortality in patients presenting with sepsis although glycemia of first day was associated with severity.
