Fluid homeostasis and oedema

Learning outcomes Basic physiology Pathophysiology of oedema Normal fluid homeostasis About 2/3rds of the total body weight is composed of water. The water content may vary according to age, sex (adult male ~ 60%, female ~ 55%) and muscle mass. žInfants have higher water content (~80%) and elderly lower content (50 – 55%). The total…

Disseminated intravascular coagulation (DIC)

Learning outcome Describe the causes, pathophysiology, clinical and laboratory features of disseminated intravascular coagulation (DIC) Pathophysiology Disseminated intravascular coagulation (DIC) is a complex haemorrhagic disorder caused by uncontrolled activation of the coagulation cascade, usually upon inappropriate release of tissue factor (TF). Other factors such as bacterial components, snake venom and products of conception may also…
