Cognitive Recovery by Decade in Healthy 40- to 80-Year-Old Volunteers After Anesthesia Without Surgery.
Postoperative delirium and postoperative cognitive dysfunction are the most common complications for older surgical patients. General anesthesia may contribute to the development of these conditions, but there are little data on the association of age with cognitive recovery from anesthesia in the absence of surgery or underlying medical condition. ⋯ Recovery of cognitive function to baseline was rapid and did not differ between age decades of participants, although the number in each decade was small. These results suggest that anesthesia alone may not be associated with cognitive recovery in healthy adults of any age decade.

Recent studies have identified stable hemodynamics as a contributing factor to improve outcome in pediatric anesthesia. So far, most of the hemodynamic monitoring methods applied in children have been complex to apply and often not satisfactory validated. ⋯ This review will describe the principle behind dynamic capnography measurement of cardiac output and mixed venous oxygen saturation. Additionally, the methods limitations and challenges when applied in children will be delineated.

Awake anesthesia with monitored anesthesia care (MAC) might confer time benefits compared with traditional general anesthesia (GA) in the setting of single-level lumbar spine surgery. Therefore, we sought to define the quantitative time difference spent in the operating room between the MAC and GA approaches for single-level lumbar spine surgery. ⋯ We found MAC to be a safe anesthesia option for use in single-level lumbar spine surgery, which led to statistically significant benefits regarding the time under sedation and time in the operating room compared with GA. Future studies are required to understand whether MAC will require other synergistic measures to generate observable change at a health systems level.

Exposure to general anaesthesia in children may be related to deficits in certain areas of cognition. It is unclear if these deficits could be measured in the immediate postoperative period in young children. The goal of the current study was to evaluate the trajectory of cognitive function in the domains of processing speed, working memory, and fine motor skills amongst children aged 2.5-6 yr who underwent general anaesthesia for elective surgery. ⋯ General anaesthesia for elective surgery in young children was not associated with declines in working memory, processing speed, and fine motor skills in the first 3 months postoperatively, including in children with prior exposure to anaesthesia.
