DDAVP to prevent rapid correction in hyponatremia.
Bibliographic record
Abstract
Correction of hyponatremia can be complicated by brisk free water diuresis with a rise in the serum sodium (s-Na) in excess of the generally accepted rate of 10-15 mmol/l/24 hours. We describe this complication and its treatment with desmopressin (dD-AVP), in a 56-year-old female with severe hyponatremia secondary to polydipsia and antidiuretic (ADH) activity. The patient developed a large free water diuresis with a markedly dilute urine (urine osmolality 61 mmol/kg) and a rise in the serum sodium of 19 mmol/l in 19 hours despite the addition of large volumes of free water intravenously and orally. To reduce the free water excretion, desmopressin (dD-AVP) 8 microg was given intravenously. This resulted in a rise in the urinary osmolality, a reduction in the urine volume, and a 2 mmol/l reduction in the serum sodium. Thereafter, the serum sodium rose 4 mmol/l in 24 hours. There were no neurological sequellae. In cases of appropriate but rapid correction of hyponatremia secondary to rapid free water diuresis, dD-AVP can safely reduce the free water excretion, slow the rate of correction of the serum sodium and simplify the fluid therapy of the patient.

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.
