Objective:To explore the easily applicable indicators of practical value to evaluate the prognosis of acute respiratory distress syndrome(ARDS).Methods:Blood and biochemical tests and bloodgas analyses were performed upon entry into the ICUs,12 h,24 h,48 h and 72 h after that in 72 ARDS patients(who were admitted to the ICUs of our hospital from January 2000 to December 2009).Then APACHEⅡscores were achieved by combining relevant physiological parameters and laboratory results.Results:There was a statistical difference between the death group and survival group at different time points upon entering the ICUs in terms of APACHEⅡscore, alveolar-arterial oxygen difference and arterial blood lactate clearance rate.PaO_2/FiO_2 values were recorded to be statistically different between the death group and survival group 24 h,48 h and 72 h,respectively after entry into the ICUs.In addition,registered linear regression existed between APACHEⅡscore,alveolar-arterial oxygen difference or PaO_2/FiO_2 value and time. APACHEⅡscore 24 h and 72 h after entering ICUs predicted mortality with an area under the ROC curve(AUC) standing respectively at 0.919 and 0.9SS.Arterial blood lactate clearance rate 12 h, 24 h,48 h and 72 h after entering ICUs predicted mortality with an area under the ROC curve (AUC) at 0.918,0.918,0.909 and 0.991,respectively.Conclusions:APACHEⅡscore applied in combination with arterial blood lactate clearance rate is of clinical significance in assessing the prognosis of ARDS patients.
Objective: To explore the easily applicable indicators of practical value to evaluate the prognosis of acute respiratory distress syndrome (ARDS). Methods: Blood and biochemical tests and bloodgas analyzes were performed upon entry into the ICUs, 12 h, 24 h, 48 h and 72 h after that in 72 ARDS patients (who were admitted to the ICUs of our hospital from January 2000 to December 2009) .Then APACHE II scores were achieved by combining relevant physiological parameters and laboratory results. Results: There was a statistical difference between the death group and survival group at different time points upon entering the ICUs in terms of APACHE IIscore, alveolar-arterial oxygen difference and arterial blood lactate clearance rate. PaO_2 / FiO_2 values were recorded to be statistically significant between the death group and survival group 24 h, 48 h and 72 h, respectively after entry into the ICUs. In addition, registered linear regression existed between APACHE II score, alveolar-arterial oxygen difference or P aO_2 / FiO_2 value and time. APACHE Ⅱ score after 24 h and 72 h after the ICU predicted mortality with an area under the ROC curve (AUC) standing respectively at 0.919 and 0.9SS. Arterial blood lactate clearance rate 12 h, 24 h, 48 h and 72 h after ICU predicted mortality with an area under the ROC curve (AUC) at 0.918, 0.918, 0.909 and 0.991, respectively. Conclusions: APACHE II score applied in combination with arterial blood lactate clearance rate is of clinical significance in assessing the prognosis of ARDS patients.
