GastrointestinalAll SpeciesNew

Key Points

Paralytic ileus is reduced or absent gastrointestinal motility without a physical obstruction
- It must always be differentiated from mechanical obstruction
It occurs secondary to an underlying cause (e.g. post-op inflammation, endotoxaemia, pain)
Can occur in any species but is particularly common in horses
Clinical signs include reduced gut sounds, abdominal distension and reduced faecal output with vomiting (small animals) or gastric reflux (horses)
Treatment requires correction of the underlying cause and supportive care with IV fluids, gastric decompression & prokinetics
