Emergency patients are uniquely challenging because their conditions can change fast, and the most dangerous problems often appear before the full picture of illness or injury becomes clear. An animal may arrive with a sudden trauma, a toxin exposure, a rapidly worsening chronic disease, or complications from another illness. Even postoperative patients must be treated as critical until life‑threatening anesthetic or surgical complications are ruled out.
In emergency medicine, one principle guides everything: treat the most life‑threatening problems first. Stabilization always comes before diagnosis. Once the patient is no longer in immediate danger, you can shift into careful monitoring to watch for improvement, deterioration, or new complications.
Many factors influence how successful emergency treatment will be. These include the severity of the primary problem, how much blood or fluid has been lost, the animal’s age and medical history, the number of other conditions present, how quickly treatment begins, the type and amount of fluids given, and any complications from either the disease or the therapy itself. In short, emergency care must be delivered at the right time, in the right amount, and in the right order. When things go wrong, it’s often because a critical moment passed without timely action.
Emergency care actually begins before the patient even arrives. The owner’s first phone call is an opportunity to give lifesaving instructions about first aid and safe transport. Meanwhile, the clinic must be prepared—especially if multiple critical patients arrive at once.
When the animal reaches the clinic, the first step is the primary survey, or triage. This is a rapid assessment focused on the ABCs: airway, breathing, and circulation. Any life‑threatening issue identified here is treated immediately. Only after the patient is stabilized do you move on to the secondary survey, a more detailed history, physical exam, and targeted diagnostics to uncover the underlying cause and guide further treatment.
