To study the fibrinogen metabolic changes in relation to coagulation disorder in patients with severe burns and trauma injuries. As a result of the burn or trauma injury breakdown of fibrinogen is accelerated.

Further study details as provided by United States Army Institute of Surgical Research:

Primary Outcome Measures:
  • During the flow phase following burn or trauma injury, fibrinogen degradation is accelerated [ Time Frame: 7 ]

Secondary Outcome Measures:
  • Fibrinogen degradation stimulates fibrinogen synthesis at the expense of whole body protein catabolism [ Time Frame: 7 days ]

Enrollment: 30
Study Start Date: February 2005
Study Completion Date: January 2014
Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Healthy Volunteers
Healthy Volunteers
Burn patients
Patients who have sustained burn injury greater than or equal to 20% of total body surface area
Trauma patients
Patients who have undergone trauma

Detailed Description:
In this protocol, we will investigate fibrinogen metabolism in burn and trauma patients, using an 8h infusion of stable isotopes labeled amino acids (1-13C-phenylalanine, 2H5-phenylalanine, and 2H3-ketoisocaporate). The increase of the labeled amino acids incorporating into fibrinogen during the infusion and the decay of labeled fibrinogen after stopping the isotopes infusion (as measured by GC-MS) will be used to calculate fibrinogen synthesis and degradation. Stable isotopes are non-radioactive.
