DEX, Delirium and Dilemma.

Abstract

Dexmedetomidine has been subjected to an extensive evaluation for its' role in the prevention of postoperative delirium following cardiac surgery. In striking contrast to the preexisting meta-analysis supporting postoperative delirium-reduction with dexmedetomidine, few recently concluded multicentric large scale randomized controlled trials suggest otherwise. This article aims to present a nuanced perspective of the evolving controversy by attempting to decode the apparent incongruences in the literature accumulating off-late, which is particularly pertinent amidst an ever-escalating heterogeneity in the current research ecosystem.
