Severe Bradycardia During Neurosurgical Procedure
Bibliographic record
Abstract
Hemodynamic alterations are observed in various neurosurgical procedures and commonly related to different neurogenic mechanisms. However, anesthetic influences on causation of these perturbations or management are rarely investigated and therefore our present knowledge is still limited.In this case of 43-old Caucasian male, propofol boluses aborted the trigeminal cardiac reflex (TCR) induced severe bradycardia during dural manipulation. There is a correlation of severity of bradycardia and slightness of anesthesia.In the light of the larger distribution of the TCR all over the world, we see more and more aborted TCR, as seen in the present case; then the neuro-anesthesists more and more recognize the TCR at its very onset. A surrogate model for the daily use is present to underline the clinical needs.We have therefore developed, for the first time, a surrogate model that helps in daily practice to recognize and prevent TCR episodes.

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.
