Hypnosis Versus SIVOC by Remifentanil During TAVI Procedures : Iloact on Peripoperative Confusion

TAVI has become a credible alternative to conventional cardiac surgery in aged high-risk patients with aortic valve stenosis. A large part of these procedures are performed with sedation using remifentanil target-controlled infusion plus local anesthesia. However, a significant proportion of the patients experience postoperative delirium, with subsequent worsened outcomes, time-consuming interventions, and increased costs. The use of hypnosis before and during TAVI could decrease the incidence of postoperative delirium thanks to less opioids and hypnotics consumption. Thus, the investigators ought to evaluate the potential advantages of hypnosis vs. remifentanil target controlled-infusion during TAVI procedures.
