OBJECTIVE: To determine the clinical value of arterial blood lactic acid monitoring in patients after cardiac surgery.
METHODS: Relationship between dynamic blood lactic acid level and the prognosis of 200 patients (9 patients in the dead group, and 191 patients in the healing group) was analyzed after cardiac operation.
RESULTS: The level of blood lactic acid was (1.2+/-0.3) mmol/L in the healing group,and (5.6+/-0.9) mmol/L in the death group. The level of blood lactic acid in the healing group descended to normal in 24 hours, while that in the death group rose persistently. The dynamic change of lactic acid indicated more sensitively the prognosis of the disease than pH and BE.
CONCLUSION: The higher the arterial blood level of lactic acid, the longer the duration, the more critical the condition, the higher the mortality rate. Blood lactic acid level can be used as an excellent prognosis index for patients after cardiac surgery.
