Pediatric shock

Shock is an acute clinical syndrome of insufficient vital organ circulation perfusion caused by a variety of reasons, leading to ischemia, hypoxia, metabolic disorders, and impaired organ function. The reduction of effective circulating blood volume is the common pathophysiological basis of shock caused by different causes. As one of the more common clinical critical illnesses, research and understanding of the pathogenesis of shock are increasing. From the microcirculation theory to the cell and molecular level, in-depth research has been made on all aspects of shock occurrence and development, and great progress has been made It also guides clinical practice, laying a necessary foundation for improving the success rate of rescue and improving the prognosis.
