Abstract:
Objective To explore the significance of dynamic determination of arterial blood gas for early diagnosis, treatment and prognosis of patients with acute respiratory stress syndrome(ARDS). Methods The results of 655 times arterial blood gas assayed in 113 patients with ARDS were analysed retrospectively.Results (1)Types of acid-basic disturbance:The simple acid-base disturbances were 44 cases,in which respiratory alkalosis were 20 cases, respiratory acidosis 11 cases, metabolic acidosis 10 cases, metabolic alkalosis 3 cases. Complex acid-base disturbances were 53 cases,in which respiratory alkalosis with metabolic acidosis were12 cases, respiratory alkalosis with metabolic alkalosis 14 cases, respiratory acidosis with metabolic acidosis 21 cases, respiratory alkalosis with metabolic alkalosis 6 cases. Triple acid-base disturbances (TABD) were 16 cases, in which the type of respiratory alkalosis were 11 cases, the type of respiratory acidosis 5 cases. the types of acid-base disturbances in cured patients mainly were respiratory alkalosis (17 cases) and respiratory alkalosis with metabolic alkalosis (12 cases). The types of acid-base disturbances in dead patients were mainly respiratory acidosis with metabolic acidosis (19 cases),TABD (14 cases) and respiratory acidosis (9 cases).(2)The oxygenation indexes(PaO2/FiO2) of all 113 patients were less than 26.7kPa.(3)The cured rate in 113cases was 53/113(46.0%)and the mortality was 61/113(54.0%).Conclusion Dynamic determination of arterial blood gas and calculation of index of oxygenation were of important clinical value in diagnosis and treatment of ARDS.
