Systemic capillary leak syndrome

Capillary leak syndrome was described first time about 45 years ago. Being an intensivist, it is an important entity to know as episode is often preceded by shock syndromes, low-flow states, infection, ischemia-reperfusion injuries, toxemias, or poisoning and fallout is usually Multiple system organ failure (MSOF). Cause and pathophysiology is still not clear but most cases have been found associated with monoclonal gammopathy, generally an IgG class. Capillary leak syndrome as name says is due to capillary hyperpermeability with massive extravasation of plasma macromolecules and acute phase usually lasts for 1-4 days. Clinical features are abdominal pain, generalized edema, hypotension with possible cardiopulmonary collapse. Acute renal failure is due to hypovolemia and rhabdomyolysis. 6 Now here is the tricky part. Acute phase is followed by recruitment of the initially extravasated fluid causing intravascular overload marked by polyuria and/or pulmonary edema. Edema is usually proportional to earlier fluid resuscitation !. Treatment with Terbullatine and Theophylline has been suggested. 3
