Study of Glycemic Control Effects on Brain Oxygen Levels and Recovery After Elective Urologic Surgery in Adults with Diabetes

What this Trial Is About

Researchers are investigating how different levels of blood sugar control affect brain oxygen levels during surgery and recovery afterward in people with diabetes. This observational study focuses on patients undergoing planned urologic surgery under general anesthesia, dividing them into groups based on their HbA1c levels to study the link between long-term blood sugar control and brain oxygen saturation. Participants will be grouped as non-diabetic or diabetic with varying HbA1c ranges 6-7%, 7-8%, and above 8%. During surgery, their brain oxygen levels will be continuously monitored using near-infrared spectroscopy NIRS, a non-invasive method, alongside standard heart and blood pressure measurements. The study aims to understand if poor blood sugar control worsens cerebral oxygenation during anesthesia and how it relates to recovery. Participants will have their brain oxygen saturation tracked from anesthesia start to end, with assessments of recovery after surgery. Researchers will collect preoperative HbA1c data and monitor vital signs throughout the procedure. The study will measure changes in regional cerebral oxygen saturation and explore postoperative recovery differences by blood sugar control level. Participation involves standard monitoring during surgery with no additional interventions, and informed consent is required.
