DEFINITION
Trauma is the injury caused by mechanical or chemical factors, which leads to tissue integrity damaged and loss of function.

Opened injury
Opened fracture
Chapter 2 Pathophysiology of trauma
Trauma can trigger a cascade of pathological response which includes inflammatory/immune reaction, neuroendocrine response and functional change of vital organ.
Immunomodulating
Both glucocorticoids and catecholamines directly inhibit the production of type 1 cytokines, such as IL-12, IL-2, TNF-α and INF-γ, that enhance cellular immunity and T-helper 1 (Th1) formation and conversely favor the production of type 2 cytokines, such as IL-10, IL-4, IL-13, that induce humoral immunity and T-helper 2 (Th2) formation. Thus, during an immune challenge, stress causes an adaptive Th1 to Th2 shift in order to protect the tissues from the potentially destructive actions of the pro-inflammatory type 1 cytokines and other products of activated macrophages. The homeostatic role of stress-induced Th2 shift against overshooting of cellular immunity often complicates pathologic conditions where, either cellular immunity is beneficial (e.g. carcinogenesis, infections) or humoral immunity is deleterious (e.g. allergy, autoimmune diseases).
3. Wound causing factors
