Maximizing the Efficacy of Sedation and Improving Brain Injury and Survival in Septic Patients With Acute Respiratory Failure
Ventilated ICU patients frequently have sepsis and the majority have delirium, a form of brain dysfunction that is an independent predictor of increased risk of dying, length of stay, costs, and prolonged cognitive impairment in survivors. Universally prescribed sedative medications—the GABA-ergic benzodiazepines—worsen this brain organ dysfunction. The available alternative sedation regimens, the shorter acting GABA-ergic propofol, and the alpha2 agonist, dexmedetomidine, have both been shown to be superior to benzodiazepines, and yet are different with regard to their effects on innate immunity, bacterial clearance, apoptosis, cognition and delirium. The MENDS2 study will compare propofol and dexmedetomidine, and determine the best sedative medication to reduce delirium and improve survival and long-term brain function in our most vulnerable patients— the ventilated septic patient.
This research study is led by Dr. Bogdan Tiru.

Severe dementia or neurodegenerative disease, defined as either impairment that prevents the patient from living independently at baseline or IQCODE >4.5, measured using a patient's qualified surrogate. This exclusion also pertains to mental illnesses requiring long-term institutionalization, acquired or congenital mental retardation, severe neuromuscular disorders, Parkinson's disease, and Huntington's disease. It also excludes patients in coma or with severe deficits due to structural brain diseases such as stroke, intracranial hemorrhage, cranial trauma, malignancy, anoxic brain injury, or cerebral edema.
