Primary Outcome Measures:
  • Cardiac output/index [ Time Frame: 6 hours ] [ Designated as safety issue: No ]
    The main outcome of interest is the change in cardiac index over the first 6 hours of the study period (before initiation of any other vasoactive medications). Pre-and post-cardiac index will be compared with a paired t-test. With 10 patients per study group, we have 80% power to detect a clinically significant 20% difference (0.4L/min/m2) in cardiac index between treatment assignments. Assuming the need for a non-parametric analysis a "standard" 20% increase in sample size will need sought. This yields a final 12 patient per group (n=24 total) sample size


Secondary Outcome Measures:
  • Cardiac Output/index and pulmonary capillary wedge pressure [ Time Frame: 5 days ] [ Designated as safety issue: No ]

Estimated Enrollment: 24
Study Start Date: February 2013
Estimated Study Completion Date: February 2014
Estimated Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Triheptanoin oil
The standard dose of triheptanoin oil for adults is 1-2gm/kg/24 hours. For purposes of this study, we will administer 0.25mg/kg four-times per day. The liquid study drug will be mixed into sugar-free, low fat yogurt, pudding or nutritional supplement shake, depending on patient preference.
Drug: Triheptanoin oil
Placebo Comparator: Simple sugar
0.25mg/kg of sugar syrup will be mixed into sugar-free, low fat yogurt, pudding or nutritional supplement shake four-times per day before meals.
