ReviewAnesthesia and Cognitive Outcome in Elderly Patients: A Narrative Viewpoint.
Better ways to manage preoperative, intraoperative and postoperative care of surgical patients is the bailiwick of anesthesiologists. Although we care for patients of all ages, protecting the cognitive capacity of elderly patients more frequently requires procedures and practices that go beyond routine care for nonelderly adults. This narrative review will consider current understanding of the reasons that elderly patients need enhanced care, and recommendations for that care based on established and recent empirical research. In that latter regard, unless and until we are able to classify anesthetic neurotoxicity as a rare complication, the first-do-no-harm approach should: (1) add anesthesia to surgical intervention on the physiological cost side of the cost/benefit ratio when making decisions about whether and when to proceed with surgery; (2) minimize anesthetic depth and periods of electroencephalographic suppression; (3) limit the duration of continuous anesthesia whenever possible; (4) consider the possibility that regional anesthesia with deep sedation may be as neurotoxic as general anesthesia; and (5) when feasible, use regional anesthesia with light or no sedation.

Randomized Controlled Trial Comparative StudyRegional Versus General Anesthesia: Effect of Anesthetic Techniques on Clinical Outcome in Lumbar Spine Surgery: A Prospective Randomized Controlled Trial.
There are only a few prospective clinical trials investigating the effects of different anesthetic techniques on clinical outcomes after lumbar spine surgery. The purpose of this study was to evaluate clinical outcomes in patients receiving general (GA) and regional anesthesia (RA) for lumbar spine surgery. ⋯ There was no difference in postoperative morphine consumption in patients receiving GA and RA for lumbar spine surgery. RA was associated with shorter anesthesia and transition times, lower VAS for pain at arrival at the postoperative anesthesia care unit, and higher patient satisfaction at hospital discharge.
