Use of Paracervical Block Before Laparoscopic Supracervical Hysterectomy
Bibliographic record
Abstract
Background and Objective: Some patients who undergo laparoscopic hysterectomy request overnight admission for pain management, thus increasing costs for a surgery that is safe for same-day discharge. We wanted to evaluate whether a paracervical block of bupivacaine with epinephrine before laparoscopic supracervical hysterectomy would decrease overnight admission rates, postoperative pain, and pain medication requirement Methods: This was a randomized, double-blind, placebocontrolled, parallel-group trial (Canadian Task Force classification I) at an academic medical center. Patients undergoing laparoscopic supracervical hysterectomy were randomized to a 20-mL paracervical injection of either 0.25% bupivacaine with epinephrine or 20 mL normal saline before skin incision. All providers, except the circulating nurse, were blinded. The primary outcome was overnight hospital admission rate. Secondary outcomes included postoperative pain medication use and pain scores. Analysis included t test, 2 , Wilcoxon, and ANOVA.

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.
