Outcome and medical management in dogs with lower motor neuron disease undergoing mechanical ventilation: 14 cases (2003–2009)
Bibliographic record
Abstract
OBJECTIVE: To describe the application of intermittent positive pressure ventilation (IIPV) in dogs with lower motor neuron disease (LMND). DESIGN: Multi-institutional, retrospective study (2003-2009). SETTING: Intensive care units at multiple university teaching hospitals. ANIMALS: Fourteen dogs with LMND that underwent IIPV. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The ventilatory logs of 4 teaching hospitals were searched for dogs undergoing IIPV in association with a diagnosis of acute LMND. The medical records were evaluated for signalment, specific LMND, ventilatory management and duration, complications associated with ventilation, duration of hospitalization, and outcome. Descriptive statistics were used as indicated. Fifteen records were evaluated, 1 dog was excluded since it experienced cardiopulmonary arrest (CPA) before commencement of IIPV. The median age was 7.0 years (range 10 mo to 12 y). There were 5 Labrador retrievers, 4 mixed breeds, and 5 other breeds were each represented once. Five dogs were diagnosed with myasthenia gravis, 4 dogs with polyradiculoneuritis, and 5 dogs had an undetermined LMND. Clinical signs of weakness before ventilation were present for a median of 36 hours (range 6 h to 14 d). Dogs were ventilated for a median of 109 hours (range 5-261 h). Nine dogs had temporary tracheostomies performed, and 8 dogs received nutritional support. Five dogs developed ventilator associated pneumonia. Six dogs were successfully weaned from the ventilator with a median ventilatory time of 49 hours (range 25-192 h). Three dogs survived to discharge. No single LMND was associated with a better outcome. CONCLUSIONS: High euthanasia rates and iatrogenic complications limit the ability to accurately prognosticate for affected dogs in this retrospective study, but in dogs with LMND that is severe enough to require IIPV, support may be required days to weeks.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
