Early identification of patients at risk for hemodynamic instability remains a major challenge in perioperative management. Skin conductance reflects sympathetic nervous system activity and may provide a noninvasive indicator of autonomic responses. This prospective observational study aims to evaluate whether skin conductance measurements can predict the development of hypotension following spinal anesthesia in geriatric oncology patients undergoing urologic surgery. The findings may contribute to improved perioperative monitoring and early risk stratification in this vulnerable patient population.",[58,59,60,61],"Hypotension","Urologic Neoplasms","Aged","Spinal Anesthesia","2026-03-23",{"date":64,"type":65},"2026-03-25","ACTUAL",{"date":67,"type":65},"2025-12-22",{"date":69,"type":54},"2026-05-01",{"name":5,"class":6},1]
