Prevention of Hypotension After Spinal Anaesthesia for Cesarean Section: A Systematic Review and Network Meta-analysis of Randomized Controlled Trials
Bibliographic record
Abstract
( Anaesthesia . 2020;75:109–121) The potential for maternal hypotension is one key risk of spinal anesthesia for elective cesarean delivery (CD). A variety of methods to prevent postspinal hypotension during CD are recommended in the literature. While an international consensus statement published in 2018 recommended prophylactic vasopressors for all CDs it did not take into account the risks associated with these agents. Also, a recent meta-analysis comparing different methods to prevent hypotension was inadequate to determine treatment efficacy. The aim of this study was to determine the relative efficacy of interventions, including vasopressors, to prevent hypotension associated with spinal anesthesia during elective CD.

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; both teacher heads agree on what is shown here.
