An exceptional outcome from a rare cause of postpartum haemodynamic collapse
Bibliographic record
Abstract
We present a case of a 26-year-old woman presenting with haemorrhagic shock without any overt bleeding on postpartum day 2. Work up revealed intra-abdominal haemorrhage from an unclear source in the pelvis. She was intubated, resuscitated with mostly crystalloids, and started on norepinephrine and dopamine, in a rural hospital with limited resources. She was then transferred to the closest tertiary care centre 3 h away by air. On arrival, she was hypothermic (34.9°C) and had developed severe metabolic acidosis (pH 6.89). A massive transfusion protocol was initiated. She underwent an emergency laparotomy and the origin of the active bleeding was believed to be a branch of the right internal iliac artery. Haemostasis was achieved with packing. She was subsequently taken to interventional radiology for angioembolisation of the right uterine artery as an alternative to haemostatic hysterectomy. Her final diagnosis was rupture of an extrauterine uterine artery pseudoaneurysm.

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.
