ABSTRACT

Objective:

To investigate the clinical application of continuous renal replacement therapy (CRRT) in infants with acute kidney injury (AKI) after liver transplantation.

Methods:

A retrospective study was conducted on infants with AKI after liver transplantation in Tianjin First Center Hospital from January 1, 2019 to June 1, 2021. Infants with AKI within 1 year after liver transplantation were divided into CRRT group and non-CRRT group according to whether CRRT was performed. The preoperative and intraoperative condition, the postoperative complications were compared, the risk factors of CRRT for AKI infants, the clinical characteristics of CRRT were analyzed, and the prognosis between CRRT group and non-CRRT group were compared.

Results:

① A total of 512 cases of pediatric liver transplantation were performed. A total of 189 cases (36.9%) developed AKI within 1 year after surgery, including 18 cases in CRRT group and 171 cases in non-CRRT group. ② There was no significant difference in preoperative conditions between the two groups. The duration of liver transplantation (hours 8.8±1.5 vs. 7.5±1.3) and intraoperative blood loss [mL 370 (220-800) vs. 310 (200-400)] in CRRT group were significantly higher than those in non-CRRT group. CRRT group had significantly higher incidence of postoperative complication [unplanned operation 8 cases (44.4%) vs. 14 cases (8.2%), primary nonfunction 1 case (5.6%) vs. 0 case (0%), retransplantation 3 cases (16.7%) vs. 0 case (0%), hepatic artery thrombosis 3 cases (16.7%) vs. 4 cases (2.3%), intestinal fistula 2 cases (11.1%) vs. 2 cases (1.2%)] than non-CRRT group (all P < 0.05). ③ The average start time of CRRT was 10 (1-240) days. The per capita frequency of CRRT treatment was 3.3 (1.0-14.0) times. The average duration of each CRRT treatment was 10.1 (6.0-19.3) hours, the average reduction rate of serum creatinine (SCr) was 25.6% (13.5%-45.0%) after CRRT. ④ In CRRT group, 5 patients died, the 1-year and 2-year survival rates were both 72.22%. In non-CRRT group, 6 patients died, the 1-year and 2-year survival rates were 97.1% and 96.5%, respectively. There were significant differences in 1-year and 2-year survival rates between the two groups (both P < 0.01).

Conclusions:

The incidence of AKI after pediatric liver transplantation was high, and most infants treated with CRRT were associated with serious surgical complications. CRRT was a powerful means to remove inflammatory factors and maintain the stability of circulation and internal environment, which could improve the multi-organ dysfunction effectively.
