Dexmedetomidine Diminishes Halothane Anesthetic Requirements in Rats Through a Postsynaptic Alpha 2 Adrenergic Receptor. By Segal IS, Vickery RG, Walton JK, Doze VA, and Maze M. ANESTHESIOLOGY 1988; 125:590-4. ⋯ These data indicate that the reduction of MAC caused by dexmedetomidine is mediated through α2 adrenoreceptors with no apparent involvement of either opiate or A1 adenosine receptors. Data from catecholamine-depleted rats suggest that the mediating mechanism must involve site(s) other than or in addition to the presynaptic α2 adrenergic receptors on noradrenergic neurons. The authors conclude that central postsynaptic α2 adrenergic receptors mediate a significant part of the reduction of anesthetic requirements caused by dexmedetomidine.

Observational Study
Electronically Mediated Time-out Initiative to Reduce the Incidence of Wrong Surgery: An Interventional Observational Study.
"Wrong surgery" is defined as wrong site, wrong operation, or wrong patient, with estimated incidence up to 1 per 5,000 cases. Responding to national attention on wrong surgery, our objective was to create a care redesign intervention to minimize the rate of wrong surgery. ⋯ Implementation of a forced-completion electronically mediated time-out process before incision is feasible, but it is unclear whether true performance improvements occur.
