Use of Stellate Ganglion Block to Salvage an Ischemic Hand Caused by the Extravasation of Vasopressors
Bibliographic record
Abstract
OBJECTIVE: This case report describes the successful use of early stellate ganglion block to salvage an acutely ischemic hand caused by the extravasation of vasopressors. CASE REPORT: A young man with a gunshot wound to the right inguinal area was brought to the operating room for surgical hemostasis and exploration. After discovery that the central line had been inserted in the proximity of the area of injury (right femoral vein), the vasopressor infusions were changed to a 14-gauge intravenous line inserted in the dorsum of the right hand. When the intravenous line became infiltrated, the hand was found to be swollen, cold, and underperfused. A right stellate ganglion block was immediately performed to overcome the intense peripheral vasoconstriction and, thus, re-establish circulation to the hand. CONCLUSIONS: Stellate ganglion block may prove to be an early measure in the treatment of upper-extremity ischemia caused by vasopressor extravasation.

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.
