(24 cards)
what is essential for survival of GDV syndrome
early recognition and intervention

unknown
what are predisposing factors to GDV
male, increasing age, underweight, large volume feeding, eating SID, eating rapidly, aerophagia, raised bowl, fearful, deep chested, stress, trauma, vomiting
why should a first degree relative with GDV not be used for breeding?
genetic component
feeding a dry dog food in which one of the first four ingredients is _____ predisposes GDV
oil or fat
what can influence GDV in military working dogs?
atmospheric influence
what should be recommended to clients to decrease likelihood of GDV
feed several meals, avoid stress, restrict exercise before and after meals, do not use elevated feeding bowls, don’t breed dogs with 1st degree relative with hx of HDV, prophylactic gastropexy, vet care at first sign, slow feeder dog bowl
how does the stomach rotate from the surgeon’s perspective during a GDV
stomach rotates in a clockwise direction
what is the angle of rotation of a GDV
220 to 270 usually
how does the duodenum and pylorus move during a GDV
duodenum and pylorus move ventrally and to left of midline between esophagus and stomach
how does the stomach rotate when viewed from the surgeon’s perspective during a GDV
clockwise
what can cause myocardial ischemia during GDV
caudal vena cava and portal vein compression -> decrease venous return and CO
what is an important physiologic finding associated with GDV, especially with gastric necrosis
cardiac arrhythmias
what has been implicated as causing much of the tissue damage that results in death after correction of GDV
reperfusion injury
what does abdominal palpation reveal on PE for GDV
distention and tympany
what are PE findings of GDV
splenomegaly, clinical signs of shock
what is the most valuable radiographic view for GDV
right lateral and dorsoventral radiograph
what is seen on the right lateral radiograph for GDV
pylorus lies cranial to body of stomach and is separated from the rest of the stomach - double bubble
what does free abdominal air suggest
gastric rupture
what does air within the wall of the stomach indicate
necrosis
which laboratory finding is prognostic for GDV
plasma lactate - higher values associated with gastric necrosis and poor prognosis
what is the initial objective of medical management for GDV
stabilize patient
how are GDVs medically managed
IVC, fluids, labs, abx, gastric decompression while treating for shock
what is needed for gastric decompressionow
needle decompression, trochar, stomach tube
