Using Skin Conductance to Predict Low Blood Pressure After Spinal Anesthesia in Older Adults Having Urologic Cancer Surgery

What this Trial Is About

Researchers are studying whether skin conductance measurements can predict spinal anesthesia-induced hypotension in elderly patients undergoing urologic oncology surgery. This observational study focuses on geriatric patients, who are more vulnerable to significant drops in blood pressure during spinal anesthesia due to age-related changes in autonomic regulation and cardiovascular reserve. The goal is to improve early risk identification and perioperative care in this patient group. The study involves continuous monitoring of skin conductance, a noninvasive measure reflecting sympathetic nervous system activity, during the perioperative period. Hemodynamic parameters such as blood pressure and heart rate will be recorded before and after spinal anesthesia. The relationship between skin conductance changes and the occurrence of hypotension will be evaluated up to 20 minutes following spinal anesthesia. Participants will be observed from before spinal anesthesia until 20 minutes after administration, with ongoing recording of skin conductance and vital signs. Researchers will track the number of patients who develop hypotension, experience bradycardia, require vasopressors, and assess changes in skin conductance values. This study aims to enhance monitoring strategies and risk assessment for elderly oncology patients receiving spinal anesthesia during urologic surgery.
