Trial Design |
Prospective randomised double-blind, placebo-controlled phase II single-centre trial of Simvastatin for the prevention/treatment of delirium. |
Study Aim |
The aim of this trial is to test the hypothesis that statins, which are known to have several potent anti-inflammatory effects and are considered responsible for health benefits seen beyond their simple cholesterol lowering ability, may also prevent delirium in critically ill patients. The study has three distinct objectives: |
|
1. To investigate the efficacy of statins initiated early during an ICU stay for the prevention of ICU delirium. |
|
2. To determine any improvement in related neurocognitive sequelae coupled with standard clinical outcomes. |
|
3. To study the biological effect of Simvastatin on systemic markers of inflammation as related to the number of delirium/coma free days and the potential of B-amyloid as a predictor of the risk of long term cognitive impairment. |
