Acid-base disturbance in patients with emergent critical diseases:analysis of 1 239 patients

Objective:To study the acidbase disturbance in patients with emergent critical diseases.Methods:The types of acidbase disturbance in 1 239 patients with emergent critical disease were analyzed.Results:There were 8 types of acidbase disturbance in 1 195 patients,occupying 96.46% of a total of 1 239 patients with emergent critical disease.The diffenent types of acidbase disturbance in 1 195 patients ranked as following:respiratory alkalosis (25.36%),respiratory alkalosis plus metabolic alkalosis (16.90%),respiratory acidosis (14.64%),metabolic acidosis (13.56%),respiratory acidosis plus metabolic alkalosis (10.54%),respiratory alkalosis plus metabolic acidosis (8.45%),metabolic alkalosis (6.11%),respiratory acidosis plus metabolic acidosis (4.44%).713 cases (59.67%) had simple acidbase disturbance and 482 cases (40.33%) mixed.Conclusions:Respiratory alkalosis or respiratory acidosis may exist as primary disorders of patients with emargent critical diseases.Metabolic alkalosis can occur with the development of patients′ primary disease or improper treatment.The respiratory acidosis may be induced by refractory shock,serious hypoxemia,diabetes ketosis,bleeding in alimentary canal,kidney function failure.Respiratory alkalosis plus metabolic alkalosis and respiratory acidosis plus metabolic acidosis might separately contribute to critical alkalemia and acidemia.
