Objective To evaluate the efficacy of the continuous renal replacement therapy (CRRT) for acute kidney injury (AKI) after the surgery of type A aortic dissection. Methods We retrospectively analyzed 58 hemodialysis patients with AKI after type A aortic dissection surgery in our hospital between January 2003 and January 2014.The 58 patients were divided into two groups including a bedside intermittent hemodialysis (IHD) group and a CRRT group based on the methods of hemodialysis. There were 38 patients with 29 males and 9 females at average age of 49.8± 13.7 years in the CRRT group. There were 20 patients in the IHD group with 14 males and 6 females at average age of 52.6± 11.0 years. Results Compared with IHD, CRRT had significantly greater effect on reducing the simplified acute physiology scoring system (SAPS)Ⅱscore (Ftime=60.964, P=0.000; Ftime * group=3.178, P=0.041). However, there was no significant difference in reducing the acute tubular necrosis individual illness severity index (ATN-ISI) score between the two groups (Ftime=13.803, P=0.000; Ftime * group=0.222, P=0.951). Lower incidences of dialysis-related complications including hypotension (P=0.027) and acute congestive heart failure (P=0.011) were found in the CRRT group. There was no statistical difference in operation time (P=0.367) between the two groups. While statistical differences in duration of hospitalization in intensive care unit (P=0.006), in hospital time (P=0.047), frequency of dialysis (P=0.001), and dialysis time (P=0.039) were found between the two groups. However there were no significant differences in mortality during hospital (P=0.544)and incidences of recovery (P=0.056) between the two groups. Conclusion Compared with IHD, CRRT had significantly positive effect on patients who suffered from AKI after type A aortic dissection surgery, which can help reduce incidences of dialysis-related complications, duration and cost of hospitalization in ICU.
