Article description

Summary:

• The study aim was to investigate the effect of an audiovisual distraction system(AVD) on the dose of remifentanil for perioperative sedation during transcatheter aortic valve implantation (TAVI) under monitored anesthesia care;
• Single-center prospective randomized nonblinded study;
• The study included 90 patients who underwent transfemoral TAVI implantation between July 2019 and July 2021;
• Patients were randomized into the treatment group (n = 45), including an AVD system, or the control group without additional AVD (n = 45);
• Primary outcomes: The average infusion rate (p = 0.028) and peak infusion rate (p = 0.025) of remifentanil were lower in the group with an audiovisual distraction system;
• Secondary Outcomes: No significant differences were observed in anxiety levels before and after the intervention between the groups;
• Audiovisual distraction during TAVI implantation under monitored anesthesia care serves as an effective adjunct to reduce remifentanil dosage;
• Larger population studies are needed to determine potential benefits on patient satisfaction, incidence of delirium, and possible positive effects on health care services cost.
