Objective: To investigate the impact of postoperative delirium in elderly patients. Methods: This retrospective study of our hospital included 496 cases of elderly patients after operations in the period from August 1999 to April 2000.Results: 58 cases (11.7%) expressed postoperative delirium in 496 cases of elderly patients. We also found that the incidence of ASA Ⅲ, hypoxemia and postoperative pain in patients with postoperative delirium was statistically higher than that in patients without them( P <0.05). Conclusion: We concluded that the improvement of physical conditions, intake of sufficient oxygen during operations and better methods of postoperative analgesia might be a useful way to predict the occurrence of postoperative delirium in elderly patients.
