Does perioperative hyperglycemia increase the risk of adverse events in patients with and without diabetes?
Perioperative hyperglycemia is associated with an increased risk of adverse events in patients without diabetes, but not in those with diabetes.
For NDM patients, but not DM patients, the risk of adverse events was linked to hyperglycemia. Underlying this paradoxical effect may be the underuse of insulin, but also that hyperglycemia indicates higher levels of stress in NDM patients than in DM patients.
Kotagal et al. (Fri,) studied this question.
