Changes in Sensory Block Level During a Programmed Intermittent Epidural Bolus Regimen for Labor Analgesia: A Prospective Observational Cohort Study
Bibliographic record
Abstract
( Can J Anesth/J Can Anesth. 2022;69:1471–1476) Currently, one of the most widely used methods of pain management is epidural analgesia, with drug delivery in a programmed intermittent epidural bolus (PIEB) in conjunction with patient-controlled epidural analgesia. Previously the investigators reported 2 sensory block levels associated with epidural analgesia: (1) upper sensory block level (USBL), the highest dermatome with any altered sensation to cold, and (2) lower sensory block level (LSBL), the highest dermatome with complete sensory block to cold. The purpose of this study was to further explore these sensory block levels and how they change over time with PIEB and patient-controlled epidural analgesia as a pain management method.

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.
