Dexmedetomidine infusion for sedation in a patient with myotonic dystrophy*
Bibliographic record
Abstract
Myotonic dystrophy type 1 is the most common muscular dystrophy in adults. Anaesthetic management should take into consideration the numerous body systems affected, including the musculoskeletal; respiratory; cardiovascular; gastro-intestinal; and central nervous systems. A 42-year-old man with myotonic dystrophy presented for septoplasty and bilateral inferior turbinate reductions. He had severe upper and lower extremity myotonia and weakness, pulmonary impairment with non-obstructive patterns and first-degree atrioventricular block with reduced ejection fraction. He used bilevel positive airway pressure, a cough assist device and was paced 3% of the time with a single-chamber pacemaker. To reduce potential complications associated with opioid use and general anaesthetics, an opioid-free technique was planned using local anaesthetic infiltration and sedation with a dexmedetomidine infusion. The patient maintained spontaneous ventilation and haemodynamic stability, and had an uneventful postoperative course. Dexmedetomidine is a highly selective α2-adrenergic receptor agonist that has the ability to provide sedation, analgesia and anxiolysis with a stable haemodynamic profile. Avoiding both opioids and general anaesthetics in these patients may decrease the risk of peri-operative complications.

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.
