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 (ED90) of carbetocin for women with a body mass index (BMI) <40 kg/m2, none have addressed the ED90 for obese women. This study aimed to find the ED90 of carbetocin in women with a BMI ≥40 kg/m2 undergoing elective cesarean delivery.

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.
