Abstract Background Our aim was to examine whether serial blood lactate levels could be used as predictors of outcome. Methods We prospectively studied 44 high-risk hemodynamically stable surgical patients. Blood lactate values mean arterial pressure heart rate and urine output were obtained at patient admission to the study at 12 24 and 48 hours. Results The nonsurvivors n 7 had similar blood lactate levels initially l versus l P not significant NS but had higher levels after 12 hours mmol l versus l P after 24 hours l versus l P NS and after 48 hours l versus l P NS as compared with the survivors n 37 . Arterial bicarbonate concentrations increased significantly in survivors and were higher than in nonsurvivors after 24 hours mEq l versus l P and after 48 hours mEq l versus mEq l P NS . The .
