EMLA® Cream Versus Dorsal Penile Nerve Block for Postcircumcision Analgesia in Children
Bibliographic record
Abstract
We conducted a prospective, randomized, double-blinded trial comparing preoperative application of EMLA cream and sodium chloride solution dorsal penile block (n = 31) with placebo cream and bupivacaine dorsal penile nerve block (n = 32) for postcircumcision analgesia. Pain was assessed using modified Children's Hospital of Eastern Ontario Pain Scale and the duration of block by the time to requirement of first dose of postoperative analgesic. There was no difference in Children's Hospital of Eastern Ontario Pain Scale between the two groups, but bupivacaine dorsal penile nerve block resulted in longer analgesia (P = 0.003). There were no local or systemic complications related to either technique, and there was a very small incidence of vomiting. We conclude that preoperative application of EMLA cream is an effective and simple method to produce postcircumcision analgesia with a very small incidence of adverse effects.

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.
