Perioperative Risk Factors for Postoperative Delirium in Elderly Patients with Hip Fractures

Abstract

ostoperative delirium is a major health concern in elderly patients. Which is a common complication in elderly patients that is characterized by disorders of consciousness, attention, perception, thinking, memory, mental activity, emotions and sleep-wake cycle. This complication usually occurs within 5 days after surgery, especially during the first 24 – 48 h postoperatively. POD impairs postoperative recovery, increases the burden of care, prolongs hospitalization time, increases the in-hospitalization mortality rate, and leads to long-term cognitive impairment or even permanent dementia. This prospective cohort study was conducted on 80 elderly patients with hip fractures admitted to ASU hospitals in orthopedic department to assess perioperative risk factors for postoperative delirium. Our thesis shows that 38% of our study population developed delirium preoperatively after admission, 68% developed delirium at day one postoperative versus only 37% at day two postoperatively. The average age range of all patients was 60 – 90 with mean age (68.625 ± 5.916 years). Age & gender were no statically significant with postoperative delirium. Also, history of fracture &history of falls had no relation with postoperative delirium.
