Perioperative Management of Adult Diabetic Patients. The Role of the Diabetologist

A patient should be referred to a diabetologist perioperatively in several circumstances: preoperative recognition of a previously unknown diabetes or detection of glycaemic imbalance (HbA1c <5% or >8%); during hospitalisation, recognition of a previously unknown diabetes, persisting glycaemic imbalance despite treatment or difficulty resuming previously used chronic treatment; postoperatively and after discharge from hospital, for all diabetic patients in whom HbA1c is >8%.
