Abstract：Objective To observe postoperative cognitive dysfunction (POCD) in elderly patients with hip fracture, to understand its pathogenesis, clinical manifestations, give prevention and treatment measures to promote early rehabilitation of the patients.Method Clinical data of 120 hip fracture patients were retrospectively analyzed from January 2011 to January 2014 in this hospital. All patients’ age were older than 70 years. There were 40 patients diagnosed as having POCD after surgery, to explore the clinical features, causes and prevention measures.Results After symptomatic treatment and comprehensive treatment, 25 of 40 POCD patients’ cognitive dysfunction improved within 1 week postoperatively, 13 cases improved within 2 weeks after surgery. But 2 cases still had cognitive dysfunction 6 months postoperatively.Conclusions The incidence of POCD in elderly patients with hip fracture is associated with preoperative cognitive impairment, perioperative anemia, blood loss in operation and operation time. But we should be aware that POCD is not caused by a single factor, it is not a simple sum of a variety of factors, but the multiple factors interaction.
