Study Summary

Hypothesis: During severe brain trauma (injury, surgery) the ensuing inflammatory response in the central nervous system (CNS) results in a decrease in the expression of the transporter protein p-glycoprotein (PGP) in the blood brain barrier. This loss results in the penetration into the brain of certain drugs that are normally excluded by the transporter protein. In this study the working hypothesis is that the agitation observed in patients with CNS trauma treated with morphine is related to the inflammation evoked loss of PGP in the blood brain barrier and the accumulation of the morphine metabolite 3-morphine glucuronide.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
see the ratios of cerebrospinal fluid (CSF)/blood increase with time as the inflammation progresses
Secondary outcome measures
ratios of morphine and its metabolites in CSF and blood with the RASS will determine if observed CNS stimulation occurs at a time when the levels of 3-morphine glucuronide is high on the brain side of the blood brain barrier
