===Introduction: gastric dilation and gut stasis===

 

===The difference between gastric dilation and gut stasis===

Gastric stasis must be differentiated from gastric dilation which is usually associated with intestinal obstruction. Gastric dilation develops rapidly, suddenly and unexpectedly, whereas gut stasis develops slowly and insidiously, usually followed by a painful or stressful episode. Note that a moving foreign body could mimic gut stasis except that the stomach is not impacted (stomach may or may not be impacted).

Serial radiographs (every 30 – 90 minutes) looking for gas in hindgut. If gas in hind gut this indicates that the obstruction is moving - administer NSAIDs (carprofen or meloxicam) if not already administered (see above) - followed by prokinetics if still anorectic after 2-3 hours.

Fluid accumulation in stomach leads to deficit in intra- and extra-cellular compartments. Parenteral fluids required. Give Hartmann’s IV.
