BACKGROUND Studies suggested that anesthetics administered upon the early reperfusion or "anesthetic postconditioning" could protect post-ischemic hearts against myocardial ischemia reperfusion injury (MIRI). However, the mechanism responsible for such protection was not well-elucidated. We investigated the cardioprotection induced by sevoflurane(More)
Volatile anesthetic ischemic postconditioning reduces infarct size following ischemia/reperfusion. Whether phosphorylation of protein kinase B (PKB/Akt) and glycogen synthase kinase 3 beta (GSK3β) is causal for cardioprotection by postconditioning is controversial. We therefore investigated the impact of PKB/Akt and GSK3β in isolated perfused rat hearts(More)
BACKGROUND It has been proved that sevoflurane postconditioning (SpostC) could protect the heart against myocardial ischemia/reperfusion injury, however, there has been few research focused on the electrophysiological effects of SpostC. The objective of the study was to investigate the effects of SpostC on action potential duration (APD) and L-type calcium(More)
Sevoflurane postconditioning has been proven to protect the hearts against ischemia/reperfusion injury, manifested mainly by improved cardiac function, reduced myocardial specific biomarker release, and decreased infarct size. This study is to observe the effects of sevoflurane postconditioning on reperfusion-induced ventricular arrhythmias and reactive(More)
AIM Sevoflurane postconditioning (SpostC) has been shown to protect the heart from ischemia-reperfusion (I/R) injury. In this study, we examined whether SpostC affected autophagic flux in myocardial tissues that contributed to its cardioprotective effects in rats following acute I/R injury. METHODS SD rats underwent 30 min of left anterior descending(More)
OBJECTIVE To identify the predictors of prolonged intensive care unit (ICU) stay in patients undergoing aortic arch replacement. METHODS The clinical data of 173 consecutive patients undergoing aortic arch replacement requiring deep hypothermic circulatory arrest plus antegrade selective cerebral perfusion were reviewed retrospectively. Patients who had(More)
