Preanesthetic administration of trazodone does not impact anesthetic recovery scores

Trazodone is administered to hospitalized equine patients to aid in behavioural management. The effects of trazodone on the recovery period have not been previously investigated. This retrospective study sought to determine if there was an association between trazodone administration and recovery quality, time, need for sedation, or reversal agent administration. We hypothesized that there would be no difference in recovery scores, recovery time, additional sedation, or reversal agent administration between horses that received trazodone preoperatively and horses that did not. Records were reviewed to identify horses undergoing orthopedic MRI between January 2022 and January 2025. 19 horses of these horses were administered trazodone prior to anesthesia. Thirty-eight horses that matched the case controls but did not receive trazodone were also selected.

## Description of the data and file structure

Retrospective data collected from medical records of horses anesthetized for orthopedic MRI from 2019 to 2025. Data collected included signalment, anesthetic protocols, recovery drugs administered, recovery times, and recovery complications.

**Description:** Retrospective data collected from anesthesia records of horses undergoing anesthesia for a orthopedic MRI. 19 Horses had received trazodone prior to anesthesia. 38 horses were selected as a control group. Page 1 details data collected from control horses. Page 2 details data collected from trazodone cases. Empty cells represent that there was no data to correlate with category (ie. no sedative agent administered, no complication experienced)
