Filter by:Perioperative neurocognitive disorders（PND） is a common complication during the perioperative period, which affects the patient's rehabilitation and quality of life. Animal studies have found that repeated anesthesia and operation lead to neurological disorders. However, there is currently a lack of clinical studies on the effects of repeated anesthesia on patients' neurological function. With the full liberalization of China's three-child policy, the number of women in need of childbearing has increased, and infertile women who repeatedly undergo hysteroscopic surgery under intravenous anesthesia is increasing . Therefore, it is of great significance to investigate whether repeated and repeated general anesthesia and hysteroscopic surgery affect the patient's neurological function. The purpose of this study is to explore the effect of repeated propofol intravenous anesthesia on the neurological function of patients undergoing hysteroscopic surgery.
Perioperative Neurocognitive Disorders(PND) is a common perioperative complication among the elderly, especially in the plastic surgery. Different anesthesia methods have different incidences of PND, but it's still unknow which is better between spinal anesthesia and nerve block combined with general anesthesia. We will apply a psychometric battery test which contain different cognitive domains to estimate the incidence of PND at a week a month and a year after surgery with different anesthesia methods. Study has showed that functional magnetic resonance imaging (fMRI) could detect a cognitive decline through spontaneous neuronal activity in the cortex and hippocampus. In our study, multi-mode imaging technology is used to conduct in-depth research on MRI and make correlation analysis with cognitive function.
