Fatal peri‐operative acute tumour lysis syndrome precipitated by dexamethasone
Bibliographic record
Abstract
A 3-year-old patient presented for elective adenotonsillectomy to treat symptomatic obstructive sleep apnoea. The patient had not been assessed at a pre-operative anaesthesia clinic but had undergone uneventful general anaesthesia twice in the previous two years. An uneventful operative course was complicated by the development of clinical instability over the first 6 h postoperatively culminating in cardiorespiratory arrest. Subsequent investigation demonstrated the acute development of tumour lysis syndrome in the setting of a new onset, undiagnosed acute leukaemia. The patient died on the third postoperative day. The use of dexamethasone for prophylaxis against postoperative nausea and vomiting was the likely aetiology of the acute tumour lysis syndrome in this case. This is the first documented peri-operative death due to tumour lysis syndrome after administration of dexamethasone. We discuss the various problems encountered with this case and review the recent literature and case reports on tumour lysis syndrome in the operating theatre.

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.
