Postoperative infections are a common complication. A relationship between perioperative severe hyperglycemia and postoperative infections has been found in patients undergoing craniotomy. The aim of this study is to evaluate the epidemiology of intraoperative severe hyperglycemia (BGC >180 mg/dL; 10 mmol/L) and postoperative infections (wound, urinary and prosthetic joint infection) and to investigate if severe intraoperative hyperglycemia is associated with an higher risk of early postoperative (within the 7th postoperative days) infections (wound, urinary and prosthetic joint infection).

Inclusion Criteria:
