Outcomes Study of Hyperinsulinemic Glucose Control in Cardiac Surgery
The Effect of Hyperinsulinemic Glucose Control on Outcomes Following Cardiac Surgery

Intervention / Behandling
Detaljerad beskrivning
Using a randomized, controlled design, we propose to test the primary hypothesis that normalization of blood glucose using a hyperinsulinemic-normoglycemic clamp technique reduces the risk of a composite outcome (one or more) of 30-day postoperative mortality and serious postoperative cardiac, renal, neurologic, and infectious postoperative complications in patients undergoing cardiac surgery.
Our secondary hypothesis is that hyperinsulinemic normoglycemic therapy will reduce length of stay in intensive care unit, atrial dysrhythmias, creatinine elevation, hospital readmission, all-cause and cardiac one-year mortality.

Evidence suggests that maintaining intra-operative normoglycemia during cardiac surgery while providing exogenous glucose and high-dose insulin may decrease post-operative morbidity or mortality.
