简要总结

With the acceleration of population aging, China has entered a stage of "deep aging." According to data from the Seventh National Census of Population released in 2021, the proportion of individuals aged 60 or older is 18.70%, with a total number of 264 million, while the proportion of individuals aged 65 or older is 13.50%, with a total number of approximately 190 million. As the proportion of elderly individuals continues to rise, the number of elderly patients undergoing surgical procedures has also increased significantly. Elderly individuals often suffer from multiple chronic diseases, a decline in physiological reserve function, and a reduced tolerance to anesthesia and surgery, presenting new challenges for anesthesiologists. Moreover, cognitive dysfunction is prevalent among the elderly and increases with age . Cognitive dysfunction before surgery is not only closely related to postoperative complications, delirium, further deterioration of cognitive function, and increased mortality, but also leads to longer hospital stays and higher medical expenses after surgery.Therefore, it is of great significance to timely and accurately identify whether the cognitive function of the elderly has been impaired and to actively implement targeted intervention strategies to maintain the health and prognosis of elderly surgical patients, as well as to control the social medical costs.

详细描述

1.1) To investigate the correlation between the levels of neurofilament light chain protein and the scores obtained from the Mini-Mental State Examination (MMSE).

2) Investigate the correlation between the levels of neurofilament light chain protein and the sensitivity to remazolam in elderly patients.

3) Study the factors that influence the sensitivity of remazolane in elderly patients.

2.Methods: One hundred and twenty-eight patients undergoing knee joint replacement were divided into normal cognitive group and cognitive decline group according to MMSE score.

3.MAIN OUTCOME MEASURES: (1) Age, gender, education level, BMI, ASA classification, smoking history, drinking history, cardiovascular disease history, diabetes mellitus history, hyperlipidemia history and COPD history. (2) BP, MAP, HR, degree of saturation of blood oxygen and BIS were measured after entering the room, after the level of spinal anesthesia was stable, when the patient lost consciousness (mascara reflex was lost) after the patient was injected with Rimazolam, and when the patient woke up immediately after the patient stopped taking the drug. (3) The time of consciousness loss (loss of eyelashes reflection) after the injection of rumazine, and the amount of drug injection. (4) How long the patient wakes after stopping the medication. (5) MMSE scores of patients. (6) Take 2 ml cerebrospinal fluid to measure NFL level.
