Massive surgical emphysema secondary to iatrogenic tracheal laceration
Bibliographic record
Abstract
A 78-year-old woman was admitted for a revision total hip replacement following a failed dynamic hip screw placed emergently 4 months earlier. Anaesthetic management consisted of general anaesthesia with endotracheal intubation and femoral nerve block. The patient's perioperative course was unremarkable except for a promptly recognised and corrected oesophageal intubation and a short period of breathing against a closed adjustable pressure limiting valve. In recovery, following a period of hypotension resistant to fluid therapy, she suddenly desaturated, developed severe facial and upper thoracic subcutaneous emphysema and type 2 respiratory failure. She was diagnosed with bilateral pneumothoraces, pneumomediastinum, pneumopericardium and surgical emphysema. This was treated emergently with supplemental oxygen and bilateral chest drains. A CT scan demonstrated a tracheal laceration, which was managed conservatively in the critical care unit. The patient had a tracheostomy on day 5 to treat an on-going air leak and later made a full recovery.

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.
