How would you evaluate an acute abdomen in a dog or cat, and what is the role of FAST ultrasound in this context?

Evaluating an acute abdomen in a dog or cat hinges on rapid triage and a structured approach that quickly flags life-threatening issues and guides intervention. Start with quick stabilization (airway, breathing, circulation) and assess perfusion and pain. A focused history and physical exam help identify signs of shock, peritoneal irritation, vomiting, or trauma, while serial observation can reveal deterioration or improvement. Laboratory work (CBC and chemistry) provides clues about anemia, infection, electrolyte disturbances, organ function, and overall metabolic status, helping to gauge how urgently the abdomen needs intervention. Imaging complements the clinical picture: abdominal radiographs give information about gas patterns, obstructions, and some organ loss of contour, while ultrasound offers real-time evaluation of the organs, presence of fluid, and other abnormalities. The role of FAST ultrasound is to quickly survey for free intraperitoneal fluid at the bedside. In an acute setting, detecting fluid can indicate hemorrhage, organ rupture, or other intra-abdominal injury and helps decide whether the patient needs immediate surgical exploration or further stabilization before more definitive imaging. It’s a fast, repeatable tool that pairs with a full abdominal ultrasound and radiographs to guide urgent decisions, rather than replacing them. So the best approach combines rapid triage, targeted history and physical, essential lab work, and imaging that includes radiographs and ultrasound, with FAST ultrasound serving as a rapid way to detect free fluid and steer the need for urgent intervention.
