Study Description

Brief Summary:

The purpose of this study is to examine the effects of insulin on helping burn patients recover faster from their burns.

Condition or disease	Intervention/treatment	Phase
Burns	Drug: Insulin Drug: Stable Isotopes Drug: Indocyanine Green	Not Applicable

Detailed Description:

Severe injuries produce profound hypermetabolic stress responses which cause severe loss of lean body mass and muscle wasting, immunologic compromise, slowed wound healing, and related bone loss, all which contribute to increased morbidity, mortality, and prolonged recovery from injury. The results of hypermetabolism persist for weeks to months depending on the severity of the insult. Massive burns can cause severe catabolism and are an excellent model to study the general effects of injury on protein metabolism. Severe burns are characterized by dramatic increases in energy utilization and alterations in the metabolism of carbohydrates, fat, and protein.

Insulin treatment improves net protein synthesis in the severely burned, principally through improved muscle protein synthesis. Although controversy exist as to whether insulin is effective as an anabolic hormone through increasing protein synthesis or decreasing protein breakdown, we believe that consideration of the methods and experimental protocols used in the various studies bear consideration when evaluating this topic.

Outcome Measures

Primary Outcome Measures :

To determine the effect of euglycemic hyperinsulinemia throughout the hospital course on net muscle protein synthesis, and to relate continued muscle anabolism to improved lean body mass and improved functional recovery in severely burned patients [ Time Frame: 45 days ]
To assess the relationship of insulin physiologic and molecular effects on skeletal muscle in severely burned patients [ Time Frame: 45 days ]
