Carbetocin at Elective Cesarean Section: A Sequential Allocation Trial to Determine the Minimum Effective Dose in Obese Women
Bibliographic record
Abstract
( Anaesthesia . 2020;75:331–337) Uterotonics are widely used in cesarean deliveries to prevent postpartum hemorrhage, which can cause maternal death or severe morbidity. Obesity, among other factors, has been implicated as a contributing factor to the rise in atonic postpartum hemorrhage in developed countries. The use of carbetocin, a synthetic oxytocin analogue, is associated with a reduced need for uterotonics in cesarean deliveries. While previous studies found 90% effective dose (ED 90 ) of carbetocin for women with a body mass index (BMI) <40 kg/m 2 , none have addressed the ED 90 for obese women. This study aimed to find the ED 90 of carbetocin in women with a BMI ≥40 kg/m 2 undergoing elective cesarean delivery.

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.
