Objective: In our study the factors related to anesthesia and peroperative variables associated with postoperative mortality among patients aged ≥65 years who had undergone orthopedic surgery were assessed. Methods: Reports on patients aged ≥65 years who had undergone orthopedic surgery between 2015 and 2017 were investigated retrospectively. Results: A total of 135 patients were included in the study. The operations comprised implantations of total hip prosthesis in 26%, total knee prosthesis in 18%, fixation of lower extremity fractures in 24, and upper extremity fractures in 14%, and amputation surgery in 17% of the patients. The postoperative mortality rates were highest (76.9%) among patients who underwent amputation surgery (p<0.05). It was found that anesthesia type, whether regional or general, was not related to mortality. Mortality was found to be associated with increasing age, ≥3 ASA score, emergency surgery, ≥3 accompanying diseases, prolonged preoperative hospital stay and low preoperative hemoglobin (Hb) values (p<0.05). Patients developing postoperative complications, those who were monitored in intensive care unit (ICU) and required mechanical ventilator (MV), and patients with prolonged ICU and hospital stay had higher mortality rates (p<0.05). 9% of all patients were determined dead. Conclusion: Among geriatric orthopedic surgery patients, apart from gender and anesthesia method, increasing age, high ASA scores, emergency surgery, the number of accompanying diseases, duration of preoperative hospital stays, low preoperative Hb values, postoperative complications requiring ICU-MV and prolonged ICU and hospital stays were all factors that affected postoperative mortality. We believe that detailed preoperative assessment and perioperative clinical management are essential if postoperative prognosis after geriatric orthopedic surgery is to be improved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
