Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a pragmatic phase III, randomized, blinded, double placebo-controlled, three-arm trial of elderly patients following cardiac surgery to assess the relationship between nighttime intravenous (IV) and sublingual dexmedetomidine on postoperative delirium and functional outcomes after surgery.
