Effects of Sevoflurane and Nitrous Oxide Anesthesia on Spatial Recognition in Aged Rats
摘要
Abstract
Objective:To compare the effects of sevoflurane and nitrous oxide anesthesia on spatial recognition in young and aged rats .Methods :Young(3 months ,n=12) and aged(18 months ,n=12) rats were divided randomly into anesthesia group (sevoflurane at 1 minimum alveolar concentration ,70% nitrous oxide ,30% oxygen ,for 4 h ,n=6) and control group(30%oxygen ,for 4 h ,n=6) .After 48 h ,training on spatial learning and memory (probe trial) were done in the Morris water maze for 6 days .Spatial exploration test was conducted at 24 h after training .Result:Sevoflurane and nitrous oxide exposure induced a significant deficit in spatial recognition in aged rats ,but not young rats .Conclusions :A significant deficit in spatial recognition in aged rats can be induced by sevoflurane and nitrous oxide exposure ,which may due to that the aged brain is more susceptible to anesthetic‐mediated changes .关键词
