title: [Free radicals and hepatic ischemia-reperfusion].
abstract: The critical importance of the ischemic-reperfusive injury is well documented with regards to numerous organs and clinical conditions. Oxygen free radicals play a central role in the mediation of the injury, which dominantly influences the prevalence of postoperative complications, (long term) organ damage, and the potential manifestation of systemic reactions. The both anatomically and pathophysiologically unique ischemic-reperfusive injury of the liver, which is expressively vulnerable to free radicals, is of utmost importance in liver surgery. Several techniques (adaptive maneuvers, chemical agents) are known to ameliorate the reperfusive injury. Based on the prior research of the workgroup of the author, the aim of the current article is to overview the set of measures capable of attenuating ischemic-reperfusive injury (ischemic preconditioning, -perconditioning, administration of adenosine, -inosine, -levosimendan, and -poly-ADP-ribose-polymerase inhibitor), with special attention to the ischemic-reperfusive injury of the liver, as well as the special pathophysiological role of free radicals in mediating hepatic damage.
