Article Description:­­­­

This is a multicentre, pragmatic, single-blind, randomised controlled trial. It was conducted in 36 centres in 13 countries.
A total of 5400 patients scheduled for coronary artery bypass grafting (CABG) were randomly assigned to receive volatile anaesthetics (n = 2709) or total intravenous anaesthesia (n = 2691).
Cardiopulmonary bypass was used in two-thirds of the patients.
The primary outcome was deaths from any cause was seen at 1 year.
The data and safety monitoring board advised that the trial should be stopped for futility at the time of the second interim analysis.

Summary:

Volatile anaesthetics are known to have cardioprotective properties, which in turn, might have favourable clinical outcomes over TIVA in patients undergoing CABG surgery.
It was a pragmatic trial with no specific drug administration protocol, only volatile OR TIVA with 2.3% crossover between the two techniques to simulate the real practice.
Regarding results, there were no significant difference between groups in mortality from any cause at 1 year (The primary outcome) (2.8% in the volatile anaesthetics group and 3.0% in the total intravenous anaesthesia group; relative risk, 0.94; 95% confidence interval [CI], 0.69 to 1.29; P=0.71). The data were available for 99.9 % of patients.
Secondary outcomes, also, showed no significant differences including myocardial infarction.

Conclusions:

The authors concluded the safety of general anaesthesia by either technique (volatile anaesthetics and TIVA) for patients undergoing CABG.

Tell us: which is your routine anaesthesia technique during CABG surgery?
We look forward to receiving your valuable comments!
