右美托咪定联合高位髂筋膜阻滞对老年髋部骨折术后认知功能恢复的影响

Objective To explore and analyze the impact of dexmedetomidine combined with high ilioinguinal fascial plane block on cognitive function recovery after hip fracture surgery in elderly patients. Methods A retrospective analysis was conducted on the medical records of 102 elderly patients who underwent hip fracture surgery in the hospital from January 2022 to June 2025. Among them, 51 patients from January 2022 to December 2023 formed the control group and received conventional anesthesia, while 51 patients from January 2024 to June 2025 formed the observation group and received dexmedetomidine combined with high ilioinguinal fascial plane block. Clinical indicators, postoperative pain levels, stress response status, patient-controlled intravenous analgesia usage, and cognitive function were compared between the two groups. Results The stay time in the anesthesia recovery room of the observation group was shorter than that of the control group(P<0.05). The postoperative pain scores of the observation group were lower than those of the control group(P<0.05). The cortisol and norepinephrine levels in the observation group at 24 hours after surgery were lower than those in the control group(P<0.05). The time for the first self-administered intravenous analgesia after surgery in the observation group was longer than that in the control group, and the number of presses and the number of rescue analgesia times were lower than those in the control group(P<0.05). The cognitive function of the observation group was higher than that of the control group at 1 day, 3 days, and 7 days after surgery(P<0.05). Conclusion Dexmedetomidine combined with high ilioinguinal fascial plane block can better mitigate the impact on patients' cognitive function while further improving clinical indicators, postoperative pain levels, stress response status, and patient-controlled intravenous analgesia usage, making it worthy of promotion and application.
