RESUMEN
Objective To investigate the incidence and risk factors of acute kidney injury (AKI). Methods The clinical data of 438 patients with severe pneumonia who were admitted in the intensive care unit in 2016 were retrospectively analyzed for analysis of AKI and assessment of risk factors. Results Among the 438 patients with severe pneumonia,the incidence of AKI was 53.42%. Within 72 hours after admission into the ICU, 86.75% of them developed AKI mainly from hypovolemic or septic shock(accounting for 80.34%). The detection rate of AKI by the standards of RIFLE and AKIN was lower than by the standards of KDIGO (45.89%,48.17%vs. 53.42%). Anemia ,shock /hypotension ,drugs ,RRT ,APPACHE II scores were the predictors of AKI. Conclusions The incidence of severe pneumonia complicated with AKI is high. Most of the patients develop it in 72 hours after admission into the ICU. Anemia,shock/hypotension,drugs,RRT,APPACHE II scores are its risk factors.
