An inflammatory stimulus (eg, a bacterial toxin) triggers production of proinflammatory mediators, including tumor necrosis factor (TNF) and interleukin (IL)-1. The pathophysiology of sepsis-induced myocardial dysfunction has not yet been defined, and topics range from patho-mechanisms to treatment. The potassium channel is also affected during sepsis and an increased influx of potassium occurs in myocytes during repolarization. The clinical perception surrounding the role of hypothermia in sepsis contrasts with experimental studies in which the hypothermia induced by bacterial endotoxin in rats was shown to be a regulated, often transient thermoregulatory response that is brought about by downregulation of thermogenesis in conjunction with cold-seeking behavior (1, 39). An inflammatory stimulus (eg, a bacterial toxin) triggers the production of proinflammatory mediators, including TNF and IL-1. Pathophysiology of sepsis . OVERVIEW.
