To determine if one treatment group does better than the other, the team's study nurses will obtain the following outcome measures: 1) ICP-TIL, 2) duration of coma, 3) in-hospital mortality, 4) Glasgow Outcome Score, 5) Disability Rating Scale, and 6) Galveston Orientation and Amnesia Test. The DSMB will monitor these outcomes by treatment group (A versus B) in order to promptly identify any between-group differences. If significant differences are noted, the code will be broken and our findings will be immediately reported to the Emory IRB, the FDA, the NINDS and DSMB.
