Objective To study the occurrence situation and risk factors of delirium after hip fracture surgery in the elderly. Methods A total of 180 elderly patients with hip fractures in our hospital from December 2014 to January 2019 were selected as the study subjects, and all underwent surgical treatment. The occurrence situation of delirium during hospitalization were investigated and they divided into the delirium group and non- delirium group. Multivariate logistic regression analysis were used to investigate the risk factors of delirium after hip fracture surgery in the elderly. Results Delirium occurred in 42 patients of 180 patients during hospitalization, with an incidence of 23.33%. Surgical methods, postoperative mechanical ventilation, Hamilton depression scale (HAMD), anxiety scale (HAMA), partial arterial oxygen pressure (PaO2), midazolam, injury to operation time, age and operation time of the delirium group and non- delirium group were statistically significant (P<0.05). There was no significant difference in gender and surgical bleeding between the two groups (P>0.05). Multivariate logistic regression analysis showed that hip replacement, postoperative mechanical ventilation, HAMA ≥ 14 points, use of midazolam, and PaO2 <83mmHg were risk factors for delirium after hip fracture surgery in the elderly. Conclusion The incidence of delirium after hip fracture in the elderly is higher. Hip replacement, mechanical ventilation, anxiety, midazolam use, and low PaO2 all increase the risk.
