“…(27) In the present study, the amount of peroxidation-derived aldehydes was increased in the lung homogenates after 30 min of MV. Due to their stability, lipid peroxidation-derived aldehydes can diffuse within or even escape from the cell and attack targets far from the site of the original free radical event.…”

“…In humans there is evidence of increased systemic lipid peroxidation and the formation of free radicals in acute respiratory distress syndrome [24], pancreatitis [25], bypass surgery [22], burn injury [26], and in septic and other states of shock [7,8,27,28]. Nonocclusive intestinal ischemia or hypoperfusion occurs in these conditions.…”

“…Toxic oxygen radicals are released from the activated polymorphonuclear leukocytes [5] and may contribute to tissue injury in distant organs. Evidence of increased systemic lipid peroxidation has been observed in patients with multiple organ failure and acute lung injury [6][7][8], and a link between local ischemia-reperfusion and organ dysfunction has been suspected. We hypothesized that gradual intestinal ischemia and subsequent reperfusion would cause lipid peroxidation both locally and systemically, and thereby decrease the antioxidant capacity of plasma.…”

“…Alguns estudos têm avaliado o estado antioxidante sérico total em grupos de pacientes graves, relatando níveis elevados de peróxidos lipídicos e redução expressiva nas defesas antioxidantes, evidenciando o estresse oxidativo 19,22,23 . Uma diminuição de antioxidantes lipídicos (α-tocoferol, β-caroteno, vitamina A) e aumento da peroxidação lipídica também foram observados durante 30 dias em pacientes queimados, mesmo nos que exibiam apenas 10% de superfície corporal queimada 14 .…”
