Abstract:

Objective

To analyze the anesthesia-related risk factors of postoperative cognitive dysfunction (POCD) after hip fracture surgery in the elderly and to explore the corresponding emergency intervention strategies.

Methods

A total of 180 elderly patients with hip fractures who were admitted to the Affiliated Hospital of Xuzhou Medical University from May 2022 to February 2025 were selected as the research subjects of this study. The incidence of POCD within 7 days after surgery in all patients was recorded, and the anesthesia-related risk factors for POCD in surgery for hip fractures in the elderly were analyzed.

Results

Among 180 elderly patients with hip fractures, 38 cases developed POCD, with an incidence rate of 21.11%. There were statistically significant differences in the operation time, anesthesia time, anesthesia method, intraoperative dosage of propofol and remifentanil, whether dexmedetomidine was used during the operation, and the lowest intraoperative local cerebral oxygen saturation (rSO2) between the POCD group and the non-POCD group (P<0.05). Univariate Logistic regression analysis showed that the operation time, anesthesia time, anesthesia method, intraoperative dosage of propofol and remifentanil, whether dexmedetomidine was used during the operation, and the lowest intraoperative rSO2 were all anesthesia-related risk factors for POCD in elderly patients with hip fractures (P<0.05).

Conclusion

There are many anesthesia-related risk factors for POCD in surgery for hip fractures in the elderly; clinically, the incidence of POCD can be actively reduced through intervention strategies such as close monitoring of anesthesia depth, reasonable selection of anesthesia methods and anesthetic drugs, and combined rSO2 monitoring.
