Abstract

To explore the optimal stage of initiating continuous renal replacement therapy (CRRT) in the treatment of neonatal acute kidney injury (AKI), a total of 25 AKI neonates treated with CRRT were hospitalized at the Department of Neonatology of Shanghai Children's Hospital, School of Medicine, Shanghai Jiao Tong University (Shanghai, China) from November 2016 to June 2021. According to the renal function, the AKI neonates prior to CRRT were divided into two groups as follows: AKI stage 0‑1 and AKI stage 2‑3. The changes noted in specific indicators including renal function, electrolyte concentration, and acid‑base balance index were analyzed at 0, 12, 24 and 48 h, and at the end of the CRRT treatment. Among the 25 neonates with AKI, serum potassium, urea nitrogen and creatinine levels were significantly decreased following 12 h of CRRT treatment and reached the normal range following 24 h of CRRT treatment with a significant increase in the volume of urine. The serum creatinine levels of the neonates in the AKI stage 0‑1 group were significantly decreased following 24 h of CRRT treatment and urine output was significantly increased. At 24 h and following CRRT treatment, the levels of serum creatinine of AKI stage 2‑3 neonates were higher than those of AKI stage 0‑1 neonates (F=3.013, 5.005; P<0.05), and at all time‑points, the urine output of AKI stage 0‑1 was higher than that of AKI stage 2‑3 (F=13.785, 4.008, 0.965; P<0.05). A total of four cases of thrombocytopenia, two cases of obstruction, and two cases of hypotension were noted in the course of CRRT treatment (the occurrence rate was 8/25). Therefore, it was concluded that CRRT could be an effective measure for the treatment of AKI neonates. Thus, ideally CRRT treatment of AKI neonates should be initiated in cases characterized as AKI stages 0‑1.
