The effects of shock are initially reversible, but rapidly become irreversible, resulting in multiorgan failure (MOF) and death. The rapid progress which has been made and the results achieved in intensive care medicine are based on sound basic research, which is duly reflected in these chapters. SHOCK 1. This review addresses the pathophysiology of hemorrhagic shock, a condition produced by rapid and significant loss of intravascular volume, which may lead to hemodynamic instability, decreases in oxygen delivery, decreased tissue perfusion, cellular hypoxia, organ damage, and death.

Leptospirosis is an acute septicemic illness that affects humans in all parts of the world. Pathophysiology and management of cardiogenic shock. Sepsis, severe sepsis, and septic shock represent increasingly severe systemic inflammatory responses to infection. (4) Pathophysiology (4) Shock is classified into four categories by etiology: (1) Hypovolemic (caused by inadequate circulating volume), (2) Cardiogenic (caused by inadequate cardiac pump function),Distributive (caused by peripheral vasodilatation and mal distribution of blood flow), (4) Obstructive (caused by extra cardiac obstruction to blood flow). ...

PATHOPHYSIOLOGY OF GOUT Arno Helmberg These lecture notes accompany my lectures on pathophysiology in the study module "Musculoskeletal system" at Innsbruck Medical University. In its most severe form, sepsis causes multiple organ dysfunction that can produce a state of chronic critical illness characterized by severe … Nothing brings the body’s machinery to a grinding halt quite like the process that occurs when essential nutrients and metabolic fuel like oxygen fail to be delivered to cells to meet their demands at the moment. Shock is an acute widespread reduction in effective tissue perfusion that invokes an imbalance of oxygen supply and demand, anaerobic metabolism, lactic acidosis, cellular and organ dysfunction, metabolic abnormalities, and, if prolonged, irreversible damage and death.

SHOCKSHOCK SYNDROMESYNDROME • Shock is a condition in which the cardiovascular system fails to perfuse tissues adequately • An impaired cardiac pump, circulatory system, and/or volume can lead to compromised blood flow to tissues • Inadequate tissue perfusion can result in: – generalized cellular hypoxia (starvation) – widespread impairment of cellular metabolism Sepsis is common in the aging population, and it disproportionately affects patients with cancer and underlying immunosuppression.
