Tumor necrosis factor and monocytes are released during hemorrhagic shock

The physiological changes of cumulative hemorrhagic shock in conscious rats

“…They also enhance leukocyte-endothelial cell adhesion, stimulate chemokine secretion, and induce neutrophil activation [25]. In addition, TNF-a is increased after hemorrhagic shock [26]. In this study, TNF-a and IL1-b were increased before 12 h and peaked at 9 h, while total leukocyte count was lowest at 6 h after hemorrhage in group 1.…”

“…Norepinephrine is a more potent inhibitor of TNF-a. In contrast, TNF-a is increased after hemorrhagic shock [26]. These results demonstrate that the effects of norepinephrine are protective from tissue injury but are likely to contribute to the generalized immunosuppression following blood withdrawal [32].…”

Immune depression in musculoskeletal trauma

“…The halflife of TNF-a is less than 20 min, but this brief appearance may be sufficient to evoke marked metabolic and haemodynamic changes and activate mediators in the cytokine cascade. Some experimental studies have shown that haemorrhage significantly increases plasma levels of TNF-a [18,19], but this was not shown in a swine model of trauma/haemorrhagic shock [20]. In clinical studies, TNF-a levels were significantly increased during haemorrhagic shock [15,21], but these findings have not been proven in uncomplicated injuries [22][23][24].…”
