Epidural dexmedetomidine infusion in a patient with chronic opioid use and intractable pain following abdominoperineal resection
Bibliographic record
Abstract
Dexmedetomidine is a selective alpha 2 adrenergic agonist with known analgesic properties. Its perioperative use is associated with reduced pain scores and an opioid sparing effect. Management of postoperative pain in patients with a history of chronic opioid use can be challenging. Multimodal analgesia is recommended although the perioperative use of dexmedetomidine has not been extensively studied in this patient population. We present a case of intractable abdominal pain following open abdominoperineal resection in a patient with rectal cancer and a history of chronic opioid use. Following the introduction of dexmedetomidine into the patient's postoperative epidural solution, a noticeable decline in reported pain scores and use of breakthrough analgesia was appreciated. The analgesic efficacy of epidural dexmedetomidine in patients with a history of chronic opioid use warrants further study.

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.
