Impact of Dexamethasone on Blood Sugar Levels During and After Non-Cardiac Surgery in Adults Using Continuous Glucose Monitoring to Study Metabolic Changes

What this Trial Is About

This research aims to understand how a standard dose of dexamethasone, given during non-cardiac surgery, affects blood sugar levels in adult patients. It also evaluates whether continuous glucose monitoring CGM offers a more accurate way to track blood sugar changes compared to traditional finger-prick tests. The study involves adult patients undergoing elective non-cardiac surgery lasting more than one hour, who receive dexamethasone as part of their anesthesia care. Participants will have a CGM device placed on their upper arm about 12 hours before surgery, which will stay in place for up to 10 days after the operation. During this time, blood sugar levels will be measured continuously by the CGM and intermittently by finger-prick tests. The CGM readings are blinded so that neither patients nor clinicians can see them. No changes will be made to the patients regular care or treatments due to study participation. Throughout the study, participants will undergo standard surgical and anesthesia procedures while researchers monitor blood sugar patterns before, during, and up to 10 days after surgery. The study will assess the patterns of high blood sugar and compare glucose trends over time. No extra treatments are provided, and the study lasts for the duration of the CGM use and monitoring period.
