目的 为持续提升认知功能障碍患者的应对与处理能力，实现治疗方式的体系化与便捷化，强化临床诊疗方法的持续创新，着眼于实际，分析智能量表在老年患者全身麻醉腹腔镜手术围手术期认知功能障碍中的预防作用。方法 本次研究采取对比试验的方式，在整个研究过程中，选取2019年2月至2021年2月到我院接受治疗的100例老年患者，所有患者均需要做全身麻醉下腹腔镜结肠癌手术的老年患者，将所有患者用随机表法平均分两组，为观察组和对照组，对照组患者在护理过程中采用常规护理方式且使用蒙特利尔认知评估量表，不采用智能量表，观察组患者“,”Objective In order to continuously improve the coping and handling ability of cognitive dysfunction，realize the systematization and convenience of treatment methods，and strengthen the continuous innovation of clinical diagnosis and treatment methods，the prevention effect of intelligent scale in perioperative cognitive dysfunction of elderly patients during laparoscopic surgery under general anesthesia was analyzed with an eye to reality.Methods The study adopt the method of contrast experiment，in the process of the entire study，selected from February 2019 to February 2021 to the hospital for treatment of 100 cases of elderly patients，all patients are all you need to do to elderly patients with laparoscopic colon surgery under general anesthesia，the table with all of the patients randomly divided into two groups，the observation group and control group，respectively，in the nursing process，patients in the control group used conventional nursing methods and Montreal Cognitive Assessment Scale，but not Smart Scale，while patients in the observation group used conventional nursing methods and Montreal Cognitive Assessment Scale and Smart Scale for observation.One day before surgery，three days after surgery and one week after surgery，the accuracy rate and scores of various values in the prevention of perioperative cognitive impairment in patients of the two groups were counted.Results After the use of intelligent scale，the elderly patients can be more timely and accurate judgment of perioperative cognitive impairment，better prevention effect.The accuracy of the two groups in preventing cognitive impairment was 65.27% in the control group and 93.47% in the observation group.All the scores of the control group were higher than that of the observation group.The average score of the control group was 24.27 and the average score of the observation group was 22.45 on the day before surgery.Three days after surgery，the average score of the control group was 23.56，the average score of the observation group was 20.26;one week after surgery，the average score of the control group was 23.12，and that of the observation group was 19.78.The lower the score，the more likely the patient was to have cognitive impairment.There was significant difference between the two groups，P＜0.05.Conclusion The use of intelligent scale has a certain preventive effect on the prevention of perioperative cognitive impairment in elderly patients，which can give reminder to medical staff，so that they can treat patients in advance.And the operation is simple，practical，with clinical value.
