Anesthesia using a cardiovascular sparing protocol is recommended. Dogs should be preoxygenated. Premedication with a pure mu‐agonist opioid is useful if not already given. Fentanyl (2–5 ug/kg) is short acting, has a fast onset and can be used immediately prior to induction to reduce the dose of induction agent required. The induction agent chosen should have a rapid onset of action (e.g., propofol or alfaxalone). Compromised dogs require less induction agent than normal animals. The dog should be maintained in sternal recumbency and the head held elevated until the animal has been intubated. Nitrous oxide should be avoided as this may cause increased gas accumulation in the stomach. Clipping should be performed with the dog in lateral recumbency. Dorsal recumbency is avoided unless the stomach has been decompressed as this may worsen hypoperfusion.
