Benzodiazepine-free cardiac anesthesia for reduction of postoperative delirium in the intensive care unit (B-Free)
B-FREE is a pragmatic, multicentre, cluster crossover trial to evaluate whether a policy limiting the use of intra-operative benzodiazepine reduces post-operative delirium when compared with a policy of ‘ad libitum’ administration. The knowledge generated by this study will provide the basis for cardiac anesthesia practice guidelines.
Multi-centre, randomized cluster crossover trial
The primary endpoint is the incidence of postoperative delirium in the cardiovascular intensive care unit.
