This efficacy and safety trial will examine the effects and safety of propranolol administered to adult patients with severe burn injury. The investigators hypothesize that propranolol will provide significant benefit to adults following severe burn injury at doses that are safe and do not increase risk of adverse infectious and non-infectious outcomes.

A safety and efficacy trial is needed in order to determine the safety of propranolol treatment in adult burn patients, identify which subpopulations may be most likely to benefit from propranolol treatment and to identify propranolol dose levels that are not only safe but potentially effective.
