Abstract: Objective To explore the effects of different anesthesia methods on postoperative cognitive function and recovery of elderly patients with hip fracture. Methods A total of 100 elderly hip fracture patients admitted to the People's Hospital of Yangdong District, Yangjiang City from April 2018 to April 2021 were selected and divided into a control group and an observation group （50 cases in each group） by lottery method. The control group was treated with traditional intravenous anesthesia, while the observation group was given local infiltration anesthesia on the basis of the control group. Comparisons between the two groups were made in the onset time of pain block, operation time, Ramsay sedation scores at different time points, cognitive function, postoperative time to get out of bed, and postoperative eating time. Results There was no significant difference in the onset time of pain block and operation time between the two groups （P>0.05）. The Ramsay sedation score of the observation group was higher than that of the control group at 5 min after awakening （P<0.05）. There was no significant difference in the scores of Montreal Cognitive Assessment before or after the surgery （P>0.05）. The observation group’s postoperative time to get out of bed and postoperative eating time were shorter than those of the control group （P<0.05）. Conclusion Comparing with intravenous anesthesia, intravenous anesthesia combined with local infiltration anesthesia for elderly patients with hip fracture has a more stable postoperative sedative effect, and it can shorten the postoperative time to get out of bed and and eating without affecting the postoperative cognitive function of the patients.
