Propofol for migraine in the emergency department: A pilot randomised controlled trial
Bibliographic record
Abstract
OBJECTIVE: To test the administration of intravenous (i.v.) propofol at a procedural sedation dose compared to standard therapy for initial management of migraine in the ED. METHODS: This was an open label, randomised controlled pilot trial. Eligible patients were adults with a diagnosis of migraine and planned for treatment with i.v. medications. Patients were randomised to propofol or standard therapy groups. The primary outcome variable was time to discharge (TTD) defined as time from intervention to discharge from the ED. Secondary outcomes were safety of propofol administration and change in pain scores. A reduction of pain by ≥50% or discharge from the ED was defined as favourable. All analyses were performed on an intention-to-treat basis. RESULTS: Data from 29 patients were analysed, with 15 patients in the propofol group and 14 patients in the standard therapy group. TTD was significantly lower in the propofol group with median of 290 (interquartile range 162-500) min compared to 554.5 (interquartile range 534-639) min in the standard therapy group (P = 0.021). The hazard ratio for the defined favourable outcome of reduction of pain scores or discharge from the ED was 1.54 (95% CI 0.69-3.41). CONCLUSIONS: Initial management of migraine with i.v. propofol at procedural sedation doses significantly reduced TTD compared to standard therapy. We did not detect any significant safety concerns although the study was not adequately powered to detect safety of the intervention and requires validation.

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.
