title: [Effection of children airway foreign bodies on blood acid-base disturbances].
abstract: OBJECTIVE
  To explore the effects of children airway foreign bodies on blood acid-base disturbances.
  
  
  METHODS
  To detect the blood-gas and electrolyte of 50 cases by children airway foreign bodies (test group), they were compared with 50 cases normal children (control group). To calculate anion gap (AG), to determine types of acidbase disturbances.
  
  
  RESULTS
  The blood-gas and K+ were significant difference between that two groups. In the test group, there were 25 simple and 19 mixed acid-base disturbances; 6 acid-base balances. There were 31 high AG, 18 normal AG, one low AG.
  
  
  CONCLUSIONS
  Children airway foreign bodies can cause acid-base disturbances. It was major in simple metabolic acidosis and mixed metabolic acidosis with respiratory alkalosis, it was more in high AG-metabobic acidosis.
