Abstract:
Objective To investigate the clinical characteristics,pathogenic causes and treatment outcomes of acute kidney injury (AKI) in very old patients in order to improving the diagnosis and treatment.Methods 39 AKI patients aged ≥80 years in the department of geriatric medicine of our hospital were enrolled and followed up for 3 months.Clinical and laboratory data were analyzed and the pathogenic causes as well as the treatment outcomes were summarized.Results Among the 39 very old patients,31(79.5％) were male,8(20.5％) were female,and the mean age was (93.5±4.6) years.33 (84.6％)patients had chronic kidney diseases.The pathogenic causes of AKI were mainly as follows:urological infections (71.8％),blood volume deficiency (48.7％),cardiac dysfunction (23.1％) and hypotension (15.4％).2 to 4 pathogenic causes were co present in 64.1％ patients.Renal function was improved and recovered in 69.2 ％ patients and the death rate was 25.6％ after treatment.The main causes of death were septic shock (30.0％),multiple organ failure (20.0％),massive gastrointestinal hemorrhage (20.0％) et al.Conclusions Most of the very old patients may suffer from AKI on the basis of chronic kidney disease.AKI is often induced by multiple pathogenic causes.The main factors leading to AKI are urological infections,followed by blood volume deficiency and cardiac dysfunction.Most patients with AKI can recover after the precipitating factors are removed and supportive treatments are administered in time.Septic shock is the main cause of death.
