The Waiting-Room Hook

It was supposed to be a routine dental or spay — and the call that came instead was every pet owner’s nightmare. Anesthesia and surgery are where a lot of veterinary tragedies happen, and where a lot of malpractice questions start. Ava asked attorney Michael Benavides how California owners tell an accepted risk from a real mistake.

Ava Asks, Michael Answers — Anesthesia & Surgery, Plain English

Ava: My pet died under anesthesia. Is that automatically malpractice?

Michael, Esq.: Not automatically. Anesthesia carries genuine risk even with perfect care. It becomes malpractice when the vet fell below the standard — skipping pre-op bloodwork, mis-dosing, or failing to monitor — and that failure caused the death.

Ava: What should a careful vet do before anesthesia?

Michael, Esq.: Generally a pre-anesthetic exam and appropriate bloodwork, a plan matched to the animal’s age and health, trained staff, and real-time monitoring of vitals during and after. The records should show all of it.

Ava: What’s “informed consent” for a pet?

Michael, Esq.: The vet should tell you the material risks, the alternatives, and the cost before you agree — especially for anesthesia or surgery. If real risks were never disclosed, that’s a problem on top of any negligence in the procedure itself.

Ava: They had me sign a consent form. Does that end it?

Michael, Esq.: No. A consent form documents that you accepted the known risks of the procedure — it does not give the vet permission to perform below the standard of care. You can’t consent away negligence.

Ava: How do I find out what actually happened in there?

Michael, Esq.: The anesthesia and monitoring log. Request the complete surgical and anesthesia records in writing. The gaps — missing vitals, no recovery notes — are often as telling as what’s written.

Ava: Is a necropsy worth it?

Michael, Esq.: It can be decisive on cause of death — ideally by an independent veterinarian, not the same clinic. It’s time-sensitive, so decide quickly.

Ava: What’s the first move for a shaken owner?

Michael, Esq.: Ask for the full records in writing today, write down every conversation while it’s fresh, and don’t sign anything the clinic hands you to “resolve” it before you understand your rights.

What to Do

An anesthesia or surgical death isn’t automatically malpractice — but it’s exactly where the standard of care, the monitoring log, and informed consent get tested.
