An Up-down Determination of the Required Seated Duration After Intrathecal Injection of Bupivacaine and Fentanyl for the Prevention of Hypotension During Cesarean Delivery
Bibliographic record
Abstract
( Can J Anaesth 2017;64:1002–1008) Prolonged seated time following intrathecal injection can prevent hypotension during cesarean delivery by limiting the upward spread of hyperbaric local anesthesia, but the limited studies of this technique have shown conflicting results. This study aimed to determine the median seated time for the prevention of hypotension following intrathecal injection of either 11.25 or 15 mg of hyperbaric bupivacaine with preservative-free morphine and fentanyl. The secondary aim of the study was to measure the rates of supplemental analgesia requirements for patients with who remained seated for an extended duration after spinal anesthesia administration.

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.
