Analysis of risk factors for postoperative respiratory and circulatory complications in elderly patients with hip fracture / 中华老年医学杂志

ABSTRACT

Objective To investigate the risk factors for postoperative cardiorespiratory complications within one month after operative treatment of hip fracture in the elderly. Methods Data of clinical examination ,samples test ,CT or MRI images were collected in 665 hip fracture patients aged 60 years and over who were admitted to our hospital from January 2010 to December 2014. Risk factors for postoperative cardiorespiratory complications within one month after operation were analyzed by correlation analysis and multiple regression analysis. Results The incidence of postoperative complications in cardiovascular system was 4.5% (30/665)in all patients.The risk factors for postoperative circulatory complications included gender ,high white blood cell(WBC)counts before operation ,hypoalbuminemia ,a low hemoglobin level (＜ 35 g/L ) ,renal insufficiency , hyponatremia ,pulmonary arterial hypertension ,segmental ventricular wall abnormal motion ,abnormal ST segment changes. The incidence of postoperative complications in respiratory system was 6.9% (46/665)in all patients. The risk factors for postoperative respiratory complications included high WBC counts before operation ,hypoalbuminemia ,chronic obstructive pulmonary disease (COPD ) , bronchiectasis and emphysema ,history of respiratory failure and abnormal lung markings (P＜0.05 or P＜ 0.01 ). Conclusions The elderly hip fracture patients have high incidence of postoperative respiratory and circulatory complications , and risk factors for these complications include accompanying diseases ,hypoalbuminemia ,abnormal echocardiography and electrocardiogram and hyponatremia.
