Results of β1 and β2 Adrenergic Receptor mediated signaling following a burn injury, without and with β-blockade
Cardiac Effects |
Metabolism | Muscle Protein |
Fat Metabolism | |
---|---|---|---|---|
Burn Injury | -Increased HR -Increased hyperdynamic circulation |
Increased REE |
Degradation increased Synthesis decreased Decreased LBM |
Increased lipolysis Increased circulating TGs, FFAs Increased hepatic steatosis |
-Increased cardiac work |
