Supraphysiologic Insulin to Improve Outcomes After Surgical Treatment of Unruptured Cerebral Aneurysms

NCT00615381 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Last updated 2015-04-23

No results posted yet for this study

Summary

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

Conditions

  • Intracranial Aneurysm

Interventions

DRUG

Insulin

insulin infusion (0-10 U/hr) vs. 0.3 U/kg/hr and boluses (0-8 U) adjusted every 15 minutes during the intraoperative period to maintain intraoperative euglycemia (blood glucose levels 80-120 mg/dL)
