Abstract: To explore the effect of multi-mode analgesia combined with personalized psychological intervention on postoperative delirium in aged patients after femoral surgery,80 aged patients with femoral fracture admitted to the Department of Orthopedics of Jishou People's Hospital of Hunan Province from January 2021 to August 2023 were randomly divided into observation group (40 cases) and control group (40 cases).The observation group was given multi-mode analgesia combined with personalized psychological intervention,and the control group was given routine postoperative analgesia.The hemodynamic  index at different time after operation,blood gas index on the first day after operation,sleep quality,relief of pain and anxiety,and delirium occurrence in the two groups of patients were observed and analyzed.The results showed that compared with the control group,the patients in the observation group had lower heart rate,lower mean arterial pressure,lower resting and activity pain scores before anesthesia,at the beginning and the end of surgery;on the 1st,3rd and 7th day after surgery,the score of insomnia and the probability of postoperative delirium were lower;the blood gas indexes PaO₂,SaO₂ and OI were higher on the 1st day after surgery;and the differences in the above indexes between the two groups were statistically significant (P<0.05).It can be concluded that the method of multi-mode analgesia combined with individual psychological intervention can play an active role in maintaining the stability of respiration and circulation,improving the postoperative sleep quality,relieving the postoperative pain and anxiety,and promoting the postoperative rapid rehabilitation of the patients,and it can reduce the incidence of postoperative delirium and improve the cognitive function of aged patients,which is an important part of rapid rehabilitation surgery.
