The pathophysiology of sepsis can be regarded as a series of steps,
beginning with the invasion of normally sterile tissue by microbes and
the elaboration of various pro-inflammatory mediators. The final common
pathway is often the development of the multiple organ dysfunction
syndrome (MODS). Whereas a great deal has been learned during the past
quarter century about the inflammatory processes associated with sepsis
(and other related conditions, such as ischemia/reperfusion injury), our
understanding is far less developed with respect to the
pathophysiological events that lead to organ dysfunction under these
conditions. Nevertheless, efforts by both clinical and laboratory
scientists are leading to new knowledge in this area. The chapters in
this volume provide a state-of-the-art overview of many aspects of the
pathophysiology of organ dysfunction in critical illness.
