How to perform a gastic paracentesis in a GDV patient | VETgirl Veterinary CE Videos

This VETgirl video demonstrates how to perform a gastric paracentesis – or more commonly known as trocharization – in a dog with a gastric-dilatation-volvulus (GDV). This procedure is life-saving and easy to perform. So, how do we trocharize? Locate the most tympanic region (estimating where the stomach is), avoiding the spleen. Clip and use sterile preparation of the region, as aseptic technique is imperative. A large gauge needle or catheter (e.g., 14 or 16 ga.) should be directed into this area to alleviate gas from the stomach; the sound of hissing gas indicates appropriate placement into the stomach. Rare complications can be seen secondary to trocharization including splenic laceration, gastric perforation, or septic peritonitis. By performing trocharization, gas can be easily removed (as demonstrated by the bubbling from the extension set in the water – BTW, we don’t normally attach the catheter to an extension set and show the gas blowing off under water, but thought you’d appreciate it for the visual effect!).
