Skin Conductance for Predicting Spinal Anesthesia-Induced Hypotension in Geriatric Urologic Oncology Patients

Turkey (Türkiye)102 participantsStarted 2025-12-22

Plain-language summary

Spinal anesthesia-induced hypotension is a common and clinically significant complication in elderly patients undergoing oncologic surgery. 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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients aged 65 years and older * Patients scheduled for elective urologic oncology surgery under spinal anesthesia * American Society of Anesthesiologists (ASA) physical status I-III * Patients who provide written informed consent to participate in the study Exclusion Criteria: * Refusal to participate or inability to provide informed consent * Contraindication to spinal anesthesia (e.g., infection at puncture site, coagulopathy) * Severe cardiac conduction abnormalities or presence of a cardiac pacemaker * Severe autonomic dysfunction or known neuropathy affecting autonomic responses * Use of medications that significantly affect autonomic nervous system activity * Baseline hypotension or hemodynamic instability before spinal anesthesia * Inability to obtain reliable skin conductance measurements (e.g., severe skin lesions at electrode placement site)

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
