The Fractious Cat That Needs a Dental
A 9-year-old female spayed domestic shorthair (4.1 kg, body condition score 7/9) presents for a dental cleaning and possible extractions. She has grade 2-3 periodontal disease, heavy calculus, and a reportedly painful mouth at home. She is severely fractious: previous visits required a towel and two people, and the last venipuncture attempt was abandoned. Pre-anesthetic bloodwork from 3 months ago was unremarkable except ALT 112 U/L (reference 10-100) and a urine specific gravity of 1.020. The owner declines radiographs and declines an overnight stay. The clinic has isoflurane, a working anesthetic monitor, a Doppler, and no ventilator. The scheduled technician is newly certified and has not managed a dental under general anesthesia independently.
1. Identify the pre-anesthetic risks and gaps, and state what must be resolved before this patient is anesthetized.

Risks:
- Airway/restraint risk: a fractious cat that cannot be handled safely is an anesthesia-safety problem before it is a behavior problem. Intubation and monitoring require handling.
- Obesity (BCS 7/9): increased anesthetic risk, harder venipuncture, and greater risk with any airway compromise.
- Mild ALT elevation and USG 1.020: could reflect dehydration, hepatic lipidosis risk in an obese cat, or incidental variation. USG 1.020 in a cat is not adequately concentrated and should be repeated with a fresh sample; ALT should be rechecked.
- Stale data: 3-month-old bloodwork is not a current baseline for an elective procedure.
- Owner constraints: declining radiographs removes the ability to plan extractions and detect retained roots; declining overnight stay means the cat must be ambulatory and eating before discharge.
- Staffing: a newly certified technician should not independently manage this case without a credentialed, experienced technician or veterinarian present.
Must be resolved before anesthesia:
- A handling plan (pre-visit gabapentin or similar per veterinarian order, quiet room, minimal restraint).
- Current minimum database, including repeat ALT and USG.
- A written anesthesia plan by the veterinarian with a defined monitoring role for the technician.
- A frank conversation about why dental radiographs matter; if the owner still declines, document the declined recommendation and the associated risk in the record.
Without these, the procedure should be rescheduled, not improvised.
2. The veterinarian asks you to draft the anesthesia and monitoring plan. What belongs in it, and how do you handle the staffing gap?

Plan elements:
- Premedication: an opioid-based premed with a sedative chosen by the veterinarian to allow handling; avoid relying on physical restraint alone.
- Induction and airway: plan for intubation with a cuff check and a secure tie; the technician's job is to have the tube, laryngoscope, and suction ready before induction.
- Maintenance: isoflurane titrated to effect; without a ventilator, the technician must watch for hypoventilation and be ready to assist ventilation by hand.
- Monitoring: record HR, RR, mucous membrane color, CRT, temperature, and anesthetic depth every 5 minutes; Doppler for blood pressure; pulse oximetry if available. Anticipate hypothermia in a small obese cat and use active warming.
- Recovery: quiet, dim, warmed cage; monitor until sternal and swallowing; assess pain and appetite before discharge.
- Emergencies: know where the crash cart, reversal agents, and emergency drugs are and who draws them up.
Staffing gap: the newly certified technician can participate but cannot be the sole anesthetist. Either schedule an experienced technician or have the veterinarian remain in the room for induction and recovery. Document the assignment in the record. If neither is possible, reschedule - an elective dental is not worth an unmonitored anesthetic.
