Collapse in a mare during standing sedation with a fatal outcome
Bibliographic record
Abstract
A 6‐year‐old 559‐kg Canadian Warmblood mare with lacerations over the neck and all four limbs was presented to the Western College Veterinary Medicine. Medical treatment and wound lavage was carried out for 5 days with no clinical improvement. Ultrasonography of the gluteal region showed disruption of normal muscle architecture, predominantly on the right side. A diagnosis of compartmental syndrome was confirmed with intracompartment pressure measurements. Fasciotomy of the semimembranosus and tendinosus muscles was elected. Standing sedation was achieved with intermittent boluses of butorphanol and detomidine, and caudal epidural analgesia was performed with 13 mL of lidocaine 2 per cent. Forty minutes after the epidural injection, the mare became ataxic and fell. The horse was anaesthetised with ketamine and diazepam followed by total intravenous anaesthesia until the effects of the epidural lidocaine were presumed to have resolved. In recovery, the mare was unable to stand. The owner elected humane euthanasia.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
