Vasovagal Syncope in Penoscrotal Inflatable Penile Prosthesis Implantation Following Spinal Anesthesia
Bibliographic record
Abstract
Spinal anesthesia (SA) is increasingly recognized as a preferred alternative to general anesthesia (GA). Nonetheless, several factors must be carefully considered to ensure safe and practical application. Vasovagal syncope (VVS) or vasovagal reaction, characterized by a sudden decrease in heart rate (HR) and/or blood pressure (BP), is common during pain management procedures and SA administration in patients undergoing surgery. We report the case of a 57-year-old male who underwent SA during penoscrotal inflatable penile prosthesis (IPP) implantation. During the corporotomy closure, the patient developed a brief episode of sudden severe bradycardia and low BP, which was attributed to VVS. Penile prosthesis implantation (PPI) is commonly performed with SA. Both urologists and anesthesiologists strongly recommend identifying important risk factors, such as VVS, before SA to facilitate monitoring and rapid response to VVS during the procedure.

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.
