Modern anesthesia is generally quite safe. Most veterinary hospitals perform a physical examination and run blood tests before all procedures requiring general anesthesia to make sure your pet doesn’t have any hidden health issues. In addition, a veterinary technician should be monitoring your pet’s vital signs during the procedure, to ensure your pet’s safety or to catch and treat any potential concerns as quickly as possible. Anesthesia and patient monitoring vary from clinic to clinic. Ask your hospital what they do to protect your pet before, during, and after the use of anesthesia.
