Effect of fast-track cardiac anesthesia on myocardial oxidative damage, inflammation and nerve related peptides of patients undergoing cardiac operation

摘要

Objective:To study the effect of fast-track cardiac anesthesia on myocardial oxidative damage, inflammation and nerve related peptides of patients undergoing cardiac operation.Methods:Sixty patients with rheumatic heart disease undergoing heart valve surgery were randomly divided into the fast track group (n=30) and conventional group (n=30). Then myocardial injury indicators, mitochondrial oxidative stress indicators, inflammation indicators and nerve-related peptides of both groups were analyzed.Results: cTnI contents at T2-T4 points in time of both groups showed an increasing trend and the increasing trend of fast track group was weaker than that of conventional group; SOD contents as well as mitochondrial tristate respiratory function, respiratory control ratios and phosphorus oxygen ratios in myocardial tissue of fast track group were higher than those of conventional group, and MDA contents was lower than those of conventional group; plasma TNF-α, IL-6, IL-8, NSE, S100β and Aβcontents of fast track group were lower than those of conventional group.Conclusions:Fast-track cardiac anesthesia can protect myocardial cells, reduce mitochondrial oxidative stress, relieve inflammation and improve nerve function; it is an ideal anesthesia method for cardiac operation.
