Anesthesia & Analgesia

Anesthesia is the part of general practice where preparation and attention change outcomes most directly. The large mortality studies in small animal anesthesia found that risk rises with physical status classification and that a substantial share of deaths occur in the hours after the procedure rather than during it. The published guidelines draw the practical conclusion: assess and stabilize before induction, plan for the individual patient, monitor continuously with a dedicated person, and keep monitoring through recovery.

This hub holds our reference guides on that process and our reporting on new anesthesia and pain research. The field's reference documents include the AAHA anesthesia and monitoring guidelines for dogs and cats, the AAFP feline anesthesia guidelines, the monitoring guidelines of the American College of Veterinary Anesthesia and Analgesia, the AAHA and ISFM pain management guidelines, and the WSAVA Global Pain Council guidelines. Several of those sit behind publisher or membership walls, so each guide lists the exact sources it was drafted from, which are the guidelines we could read in full plus open-access reviews and mortality studies. Where a source describes a step as a recommendation of a panel or an author rather than a finding from trial data, the guides say so.

The pages are organized by the questions a surgery day raises. The high-risk guide covers physical status classification, what the mortality studies found about which patients carry more risk, and what the sources say about stabilization before induction. The analgesia guide covers the multimodal approach the pain guidelines describe: opioids, non-steroidal anti-inflammatory drugs, local and regional techniques, and adjuncts, each with the cautions the sources attach. The feline guide addresses the points on which cats differ from small dogs, including handling, airway management, and fluid rates. The monitoring guide sets out the parameters its sources describe tracking, and what a published checklist study found.

A note on doses. Anesthetic and analgesic doses depend on the patient, the combination, and the product, and published ranges are wide. These guides give a dose only when a cited source states it, and every such mention carries a reminder to verify against the current label or formulary and the patient's full clinical picture. The guides are a summary of published guidance, and the anesthetic plan for a given animal remains the attending veterinarian's.

Much of this material is written with technicians in mind, since in most practices a credentialed technician is the person at the patient's head. Checklists, machine checks, and recovery observation are presented in a form that can be adapted into a clinic's own written protocols.
