Effects of sevoflurane vs. propofol on mitochondrial functional activity after ischemia-reperfusion injury and the influence on clinical parameters in patients undergoing CABG surgery with cardiopulmonary bypass

Abstract: The aim of the study was to evaluate the effects of sevoflurane and propofol on the activity of mitochondrial function related to ischemia-reperfusion injury, myocardial damage biomarkers release and clinical parameters in the postoperative period. Seventy-two patients scheduled for elective coronary artery bypass graft surgery with cardiopulmonary bypass were randomized into two groups: 36 patients received sevoflurane during anesthesia (Group S) and 36 patients received propofol (Group P). To investigate the… Show more

“…Thus, effective means that can protect mitochondrial dysfunction may confer cardioprotection against myocardial I/R injury. Indeed, previous studies have shown that propofol protection of human myocardium against I/R injury was mediated by mitochondrial adenosine triphosphate-sensitive potassium channels opening and mitochondrial respiratory chain complexes in in vitro models of cardiomyocytes of hypoxia/reoxygenation [10] and in patients undergoing coronary artery bypass grafting surgery with cardiopulmonary bypass [11]. However, it is still unclear how propofol attenuates mitochondrial dysfunction during myocardial I/R to confer cardioprotection and whether or not propofol confers cardioprotection in hearts from diabetes through mitochondria protection.…”

“…The authors observed that reperfusion accelerated the development of myocardial necrosis, and the degree of myocardial necrosis following I/R for 30-60 min was similar to that observed 24 h after coronary occlusion. To date, various studies have shown that I/R injury is associated with calcium overload (6)(7)(8), the production of free radicals (9,10) and mitochondrial alterations (10,11). Cytosolic calcium overload is now well known as an essential pathophysiological mechanism which is involved in reperfusion injury, although the source and origin of the calcium remains to be determined (12).…”

“…Tyrimų nagrinėjančių mitochondrijų kvė-pavimo greitį po išeminio/reperfuzinio periodo žmogaus miokarde beveik nėra. Todėl mes su kolegomis atlikome tyrimą in situ, kurio metu tirtos žmogaus prieširdžio skaidulos, gautos aortovainikinų jungčių suformavimo operacijos metu (prieš kardioplegiją ir po išemijos/reperfuzijos) ir vertintas mitochondrijų kvėpavimo greitis [12]. Tyrime nustatėme, kad mitochondrijų išorinės membranos pralaidumo padidėjimas prieširdžio raumens skaidulose buvo jau iki išeminio/reperfuzinio periodo tikriausiai dėl to, kad pacientai, kuriems atliekama aortovainikinių jungčių suformavimo operacija, jau serga išemine širdies liga, pažeidžiančia miokardą.…”

Po reperfuzijos citochromo c stimuliuotas mitochondrijų kvėpavimas buvo dar didesnis, tai gali rodyti dar didesnį mitochondrijų išorinės membranos pažeidimą [12]. Toleikis ir kt.…”
