Snapshot of 1973 and 1974

The year 2012 marks the 40th anniversary of the Society of Neuroscience in Anesthesiology and Critical Care (SNACC). To celebrate this occasion, we provide a review, speculative synthesis, and commentary addressing research relevant to neurosurgical anesthesiology in 1973 and 1974--the early years of SNACC. We address topics such as effects of anesthetic drugs, neuroprotection, cerebral physiology, and monitoring as they relate to the perioperative care of neurosurgical patients or patients experiencing or at risk for neurological disorders. Our hypothesis is that a review of these publications will identify the foundations of research and practice concepts that persist until today and will also identify concepts that have dwindled or outright disappeared.
