title: Stomach gas analyses in canine acute gastric dilatation with volvulus.
abstract: BACKGROUND
  The origin of the gas in the stomachs of dogs with acute gastric dilatation or gastric dilatation with volvulus (GDV) often is disputed.
  
  
  OBJECTIVE
  We tested the hypothesis that gaseous distention resulted from aerophagia.
  
  
  METHODS
  Ten cases of GDV that were submitted to an emergency clinic were sampled intraoperatively.
  
  
  METHODS
  With the abdomen open, the needle of a vacutainer blood collection set was inserted into the distended stomach, and gas was collected into 10 mL glass vacutainer vials with rubber stoppers. These were stored at room temperature for 1-7 days and then analyzed by gas chromatography and mass spectroscopy.
  
  
  RESULTS
  CO2 composition ranged from 13 to 20%. One dog had an H2 concentration of 29%.
  
  
  CONCLUSIONS
  Because the CO2 content of atmospheric air is less than 1%, these findings suggest that the gaseous gastric distention in GDV is not the result of aerophagia.
