Minimizing ICU Neurological Dysfunction With Dexmedetomidine-induced Sleep (MINDDS II)

Purpose

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.

Condition

  • Delirium

Eligibility

Eligible Ages
Over 60 Years
Eligible Sex

Accepts Healthy Volunteers
