The origin of the gas in the stomachs of dogs with acute gastric dilatation or gastric dilatation with volvulus (GDV) often is disputed.
We tested the hypothesis that gaseous distention resulted from aerophagia.
Ten cases of GDV that were submitted to an emergency clinic were sampled intraoperatively.
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.
CO2 composition ranged from 13 to 20%. One dog had an H2 concentration of 29%.
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.
急性胃扩张或胃扩张扭转（GDV）犬胃内气体的来源常常存在争议。
我们检验了气体扩张是由吞气症导致的这一假设。
十例送至急诊诊所的GDV病例在术中进行了采样。
打开腹腔后，将真空采血管采血装置的针头插入扩张的胃内，气体被收集到带有橡胶塞的10 mL玻璃真空采血管小瓶中。这些样本在室温下保存1 - 7天，然后通过气相色谱和质谱进行分析。
二氧化碳含量在13%至20%之间。一只犬的氢气浓度为29%。
由于大气中二氧化碳含量低于1%，这些发现表明GDV中胃内气体扩张并非吞气症的结果。
