Randomized Controlled Trial Comparative Study Clinical Trial
Beneficial impact of isoflurane during coronary bypass surgery on troponin I release.
Experimental studies indicate that isoflurane, a commonly used volatile anesthetic, mimics the cardioprotective effects of ischemic preconditioning, probably through ATP-sensitive K+ (KATP) channel activation. The aim of this study was to evaluate the impact of isoflurane during coronary bypass surgery (CABG) on troponin I release. ⋯ Isoflurane reduces myocardial injury in patients with impaired left ventricular function undergoing CABG; thus, it can be safely used as an additional cardioprotective tool during routine CABG in high-risk patients with poor left ventricular function.
