Effect of Sevoflurane Inhalation Anesthesia on Postoperative Cognitive Function and CAM Score in Elderly Patients Undergoing Minimally Invasive Surgery

目的：分析老年微创手术患者运用七氟烷吸入麻醉的效果。方法：随机纳入从2023.02到2024.06于安徽医科大学第二附属医院行微创手术治疗的老年患者共82例，其中对照组为丙泊酚静脉麻醉41例，观察组为七氟烷吸入麻醉41例并分析麻醉质量。结果：观察组具有更短的麻醉复苏时间，麻醉10分钟后有更高的心率和平均动脉压指标，术后有更高的认知功能评分且术后谵妄发生占比低，上述结果均(P Objective: To analyze the effect of sevoflurane inhalation anesthesia in elderly patients with minimally invasive surgery. Methods: A total of 82 elderly patients who underwent minimally invasive surgery in the Second Affiliated Hospital of Anhui Medical University from 2023.02 to 2024.06 were randomly included, including 41 cases of propofol intravenous anesthesia in the control group and 41 cases of sevoflurane inhalation anesthesia in the observation group, and the quality of anesthesia was analyzed. Results: The observation group had shorter anesthesia recovery time, higher heart rate and mean arterial pressure index after 10 minutes of anesthesia, higher postoperative cognitive function score and lower proportion of postoperative delirium, all the above results (P < 0.05). Conclusion: Sevoflurane inhalation anesthesia is used for minimally invasive surgery in elderly patients. The vital signs during the operation are stable. The early postoperative recovery of cognitive function is faster and the incidence of postoperative delirium can be reduced. It has certain application value.
