| Abstract | BACKGROUND Several studies have highlighted that volatile anaesthetics improve myocardial protection in cardiopulmonary bypass coronary surgery. However, the haemodynamic effect of desflurane in off-pump coronary surgery has not been clarified yet. Our study hypothesis was that desflurane-fentanyl anaesthesia could decrease myocardial injury markers and improve haemodynamics compared to propofol-fentanyl in patients undergoing off-pump coronary surgery. METHODS DESIGN Prospective, randomised open-lable study. Sixty elective patients with left ventricular ejection fraction above 30% received either desflurane (group D, n = 32) or propofol (group P, n = 28), in addition to fentanyl and vecuronium bromide anaesthesia for off-pump coronary surgery. Assessment of haemodynamic function included thermodilution continuous cardiac output and right ventricular end diastolic volume. RESULTS No significant differences in cardiac output, stroke volume and mean arterial pressure were noted between groups. The only observed difference in haemodynamic profile was that group D demonstrated improved stability, expressed as left ventricular stroke work index (LVSWI). Decrease in LVSWI after performing distal anastomoses was smaller in D compared to P (median value: -14.3 and -19.8 [g m m⁻² beat⁻¹]), respectively (P = 0.029). Oxygen uptake index (VO₂I) and oxygen extraction ratio (OER) after skin incision were lower in D, while blood lactate concentration was slightly higher after surgery in D compared to P. The groups did not differ with respect to CK-MB and troponin I concentration. CONCLUSIONS This study demonstrated no difference between desflurane and propofol anaesthesia for off-pump coronary surgery in major haemodynamic parameters, as well as in myocardial injury markers and the long-term outcome. However, the study indicated that desflurane might accelerate recovery of myocardial contractility, as assessed by LVSWI. Lower oxygen uptake and elevated lactate under desflurane anaesthesia indicated a discrete shift towards anaerobic metabolism.
