Intravenous drug and fluid administration tasks account for a significant proportion of anesthesia care, especially in complex cases. Current processes are inefficient and may predispose to medical error. There appears to be substantial opportunity to improve quality and cost of care through the reengineering of anesthesia intravenous drug and fluid administration processes. General design requirements are proposed.

Tubbesing, V. A and Block, B. A. 2000. Orbital rete and red muscle vein anatomy indicate a high degree of endothermy in the brain and eye of the salmon shark. Ð Acta Zoologica (Stockholm) 81: 49±56The salmon shark has been ranked as the most endothermic lamnid shark based upon geographical range, extent of slow twitch muscle, supra-hepatic rete size, and limited temperature measurements, yet its anatomy has remained largely undescribed, and measurements of brain or eye temperatures have not been reported. In this study, four specimens are examined to determine if the morphological requirements for warming the brain and eyes are present. A well-developed arterial orbital rete lies within a venous sinus on both sides of the cranium. Cool, oxygenated blood from the gills can pass through the vessels of this exchanger before reaching the brain or eyes. Since venous blood in the sinus flows opposite the arterial blood, counter-current heat exchange can occur. A vein originating in the red swimming muscle likely contributes to the warmth of the venous sinus by supplying blood directly from the warmest region of the shark. Before collecting in the orbital sinus, this red muscle vein bathes the brain in warm blood. These morphological data suggest the salmon shark has a significant capacity to warm the brain and eyes.
