Preoperative bowel preparation complicated by lethal hypermagnesaemia and acute nephropathy
Bibliographic record
Abstract
Hypermagnesaemia is an uncommon but serious disorder. An elderly woman presented with severe cardiovascular collapse, neurologic depression and acute nephropathy, following bowel preparation. Urgent laboratory tests revealed serum magnesium level of 7.5 mmol/L (normal = 0.75-1.05 mmol/L). Prompt resuscitation and treatment of the hypermagnesaemia included intravenous calcium chloride as a physiological antagonist, fluid infusion and frusemide to aid renal excretion of magnesium. There are few case reports of patients who survived hypermagnesaemia levels >7 mmol/L. This is a case report of near-fatal hypermagnesaemia which resolved following early diagnosis and treatment. Hypermagnesaemia may be difficult to diagnose because serum magnesium is not checked routinely and many clinicians are unfamiliar with this uncommon condition. It is a diagnosis of exclusion and may not be recognised as a cause of neurologic or cardiorespiratory depression. Hypermagnesaemia should be considered as a possible diagnosis in elderly or high-risk patients presenting with such symptomatology.

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.
