| Objective:To identify the risk factors related to the development of the cardio-cerebral events in hospital and the 1-year mortality following lower extremity fractures surgery on elderly patients.Methods:Four hundred and thirty patients,age≥65years,undergoing elective lower extremity fracture surgery from January 2010 to December 2014 were selected.Age,gender,past medical history(hypertension,diabetes,coronary heart disease,atrial fibrillation,the cardiac and cerebral disease,hemiplegia),surgical spot(hip and femur,under the femur),anesthesia(general anesthesia and spinal anesthesia),ASA grade,preoperative anemia,operation time,intra-operative hypertension,intra-operative hypotension,the amount of bleeding,postoperative Hb≤ 90g/L in hospital and volume of drainage after operation,postoperative pneumonia and transferred to the ICU after operation were recorded.According to the development of in-hospital postoperative cardio-cerebral events,the patients were divided into either complication group or non-complication group;according to the living status in one year,the patients were divided into either survival group or dead group.If there was significant difference between the 2 groups,the factor was analyzed using multi-factor logistic regression to select the risk factors for the development of postoperative cardio-cerebral events in hospital and the 1-year mortality,respectively.Results:Three hundred and seventy-two patients completed the study,a total of thirty-five patients developed postoperative cardio-cerebral events in hospital,and the incidence was 9.4%,statistical analysis showed that the preoperative cardio-cerebral complications and ASA grade ≥ Ⅲ were risk factors for the development of in-hospital postoperative cardio-cerebral events;thirty-three patients died within one year,the overall 1-year mortality was 8.9%,logistic regression analysis showed that age≥75years,preoperative hemiplegia and the in-hospital postoperative cardio-cerebral events were the risk factors related to 1-year mortality.Conclusion:The independent risk factors for the development of postoperative cardio-cerebral events in hospital following lower extremity fractures surgery on elderly patients are the preoperative cardio-cerebral complications and ASA grade ≥ Ⅲ;age≥75years,preoperative hemiplegia and the in-hospital postoperative cardio-cerebral events are the independent risk factors related to 1-year mortality following lower extremity fractures surgery on elderly patients. |
