Comparison of APACHE II Score and Blood Lactate Clearance Rate on the Prognosis of Critically Ill Patients

Objective: To discuss the action of APACHE Ⅱscore,blood lactate clearance rate on comparison prognosis of critically ill patients. Method: 146 cases of critically ill patients were selected and divided into group A,B,C according to the level of APACHE Ⅱ score,each group were assessed blood lactate clearance rate,APACHE Ⅱ score; patients were divided into groups of death and survival group,and then assess blood lactate clearance rate,APACHE Ⅱ score.Result: 23 cases of 146 cases of death in critically ill patients( 15.8%),123 cases survived( 84.2%). Blood lactic acid level two groups B,C was higher than that in group A,the blood lactate clearance rate was significantly lower than that in group A,P 0.01,has statistical significance; group C blood lactate levels were significantly higher than that of group B,the blood lactic acid clearance rate was significantly lower in group B( P 0. 05),with statistical significance;group A,B,C blood lactate levels with 24 h the instant blood lactic acid level was low,P 0.05,with statistical significance; increase the APACHE II score of patients with blood lactate clearance rate decreases,P 0.05,with statistical significance; the death group APACHE II score was significantly higher than the survival group,P 0.05,has statistical significance; 24 h blood lactic acid levels in the two groups than the instant blood lactic acid level is low,P 0.05,the statistical significance.Conclusion: By detecting the blood lactic acid level and APACHE II score well able to assess the prevalence of critically ill patients to the doctor,treatment of patients,so as to reduce the mortality of patients.
