创伤性休克是由于机体遭受剧烈的暴力打击,重要脏器损伤、大出血等使有效循环血量锐减,微循环灌注不足,以及创伤后的剧烈疼痛、恐惧等多种因素综合形成的机体代偿失调综合征。因此创伤性休克较单纯失血性休克的病因、病理更加复杂。创伤性休克在平时及战时均常见,发生率与致伤物性质、损伤部位、致伤能量、作用时间、失血程度、患者平时生理状况和伤后早期处理有关。随着高速公路的发展及暴力犯罪的增加,严重创伤及多发伤的发生率日益增高,创伤性休克的发生率也随之增高,多发伤中休克的发生率可高达50%以上。
Traumatic shock is due to the body subjected to violent attacks, major organ injury, bleeding and other effective circulation of blood volume drastic reduction in microcirculation perfusion, as well as traumatic severe pain, fear and other factors formed by the integrated compensation of the body Disorders Syndrome. Therefore traumatic shock than the simple cause of hemorrhagic shock, pathology more complicated. Traumatic shock in peacetime and wartime are common, the incidence and the nature of injury, injury site, traumatic energy, duration of action, the degree of blood loss, the patient’s usual physical condition and post-injury treatment. With the development of highways and the increase of violent crimes, the incidence of severe trauma and multiple trauma is increasing day by day. The incidence of traumatic shock also increases. The incidence of shock in multiple trauma can reach as high as 50% or more.
