Abstract
( Anesth Analg . 2017;125(1):212–218) Phenylephrine, which is easy to titrate, is the current first-choice vasopressor for prevention and treatment of maternal hypotension during spinal anesthesia for cesarean delivery (CD). However, it has a propensity to increase afterload and reduce maternal heart rate and cardiac output. Norepinephrine has been suggested as an alternative, with a proposed potency ratio for norepinephrine to phenylephrine of 16:1, although its administration as a bolus during CD has not been established. The authors of the present study thus determined the effective norepinephrine dose (ED 90 ), when given as intermittent intravenous boluses, to prevent post-spinal hypotension in women undergoing elective CD.

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 it
