The impact of preoperative testing for blood glucose concentration and haemoglobin A1c on mortality, changes in management and complications in noncardiac elective surgery A systematic review

摘要

BACKGROUND The risks associated with surgery are elevated in patients with diabetes mellitus. For this reason, preoperative diagnostics frequently include the measurement of blood glucose and haemoglobin A(1)c (HbA(1)c), but it is unclear whether these tests contribute to improved perioperative or postoperative outcomes.
