Stopped: Study was not initiated and has been withdrawn due to lack of appropriate cases
We hypothesize that in patients undergoing surgical treatment of unruptured intracranial aneurysms, the increase in blood sugar as a result of surgical stress is detrimental to outcome, as measured by blood levels of proteins associated with systemic inflammation and 7 day, 90 day, and 1 year postoperative neurologic and neuropsychiatric outcomes. Because insulin itself is an anti-inflammatory agent, we anticipate that normalizing blood sugar levels with insulin doses higher than normally produced by the body (i.e., "supraphysiologic" insulin doses) will have a greater benefit on these outcomes than equally normalizing blood sugar levels using normal insulin doses. Based on the results of this study, we will be able to determine if a more laborious strategy to normalize blood sugar levels (i.e., "supraphysiologic" insulin therapy) offers any additional benefits to normal insulin dosing strategies. In addition, we will obtain a robust assessment of postoperative neuropsychiatric and neurologic outcomes of surgically repaired unruptured intracranial aneurysms that will serve as the basis for future studies to decrease morbidity of these patients

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Neurologic Outcome--"poor" vs. "good." A "poor" outcome is assigned if the patient who arrived independently from home is discharged to a nursing home or rehabilitation hospital or dies.
Timeframe: Discharge from hospital after surgery
