Clinical Trial Summary

Preliminary evidence suggest a possible relationship between HbA1c and perioperative neurocognitive disorders (NCD). We are going to investigate whether the preoperative value of HbA1c in patients undergoing elective non-cardiac surgery under general anesthesia, are related with increased risk of perioperative NCD.


Description:

It is estimated that approximately 10% of elderly undergoing surgery will develop cognitive changes perioperatively, while in some reports the incidence rises up to 80%. Despite the reported high prevalence of perioperative neurocognitive disorders (NCD), their exact etiology is still largely unknown. Preliminary evidence suggest a possible relationship between HbA1c and perioperative neurocognitive disorders (NCD). We are going to investigate whether the preoperative value of HbA1c in patients undergoing elective non-cardiac surgery under general anesthesia, are related with increased risk of perioperative NCD.
