Gastric myoelectric activity after experimental gastric dilatation-volvulus and tube gastrostomy in dogs.
Gastric myoelectric activity was measured after experimental gastric dilatation-volvulus (GDV), GDV and tube gastrostomy, or tube gastrostomy in 12 dogs. Gastric myoelectric activity was recorded for 1 hour before (hour 0) and at hours 5, 24, 48, 72, and 96 after surgically induced GDV in six dogs. Three dogs with induced GDV and tube gastrostomy, and three dogs with tube gastrostomy only were also studied at hours 120, 144, and 168. The only significant change in the slow wave appearance or frequency from hours 0 to 48 was bradygastria at hour 5 in all three groups. A relative increase in the mean percentages of dysrhythmia from hours 72 to 168 in the dogs with a tube gastrostomy was caused by increases in tachygastria and arrhythmias. Dogs with GDV and tube gastrostomy had the greatest mean percentages of dysrhythmia, which were significantly more than those in dogs with GDV alone at hours 48, 72 and 96. The mean percentage of spike activity was less than or equal to 31 and varied widely. In general, there was less spike activity when the frequency of dysrhythmias was high. Thus, gastric myoelectric activity was disrupted from hours 48 to 168 after GDV with tube gastrostomy and after tube gastrostomy alone. Surgically induced GDV alone did not produce any significant or sustained dysrhythmias.
Massive gastric hemorrhage induced by buffered aspirin in a greyhound.
A 13-year-old, neutered male greyhound was presented with severe hematemesis and hematochezia following only three doses of buffered aspirin that were within therapeutic recommendations. Transfusion of seven units of whole blood was required to stabilize the patient. Diagnostic evaluation failed to reveal an underlying disease state that could have predisposed the dog to massive gastric hemorrhage. This is the first report of buffered aspirin causing clinically significant disease during routine administration.
