To investigate the e cacy and safety of continuous blood puri cation (CBP) in neonates with septic shock and acute kidney injury (AKI).
MethodsA retrospective study was conducted in two tertiary care children's hospitals between January 2015 and May 2022.
ResultsIn this study, 26 neonates with septic shock and AKI were included with a mortality of 50%. Fourteen neonates (53.8%) received continuous veno-venous hemodia ltration, while 12 (46.2%) received continuous veno-venous hemo ltration. Compared with the indexes before CBP, urine output increased 12h after CBP initiation (P = 0.003), and serum creatinine decreased (P = 0.019). After 24h of CBP, blood urea nitrogen had decreased (P = 0.006), and mean arterial pressure had increased (P = 0.007). At the end of CBP, vasoactive inotropic score and blood lactate were decreased (P = 0.035 and 0.038), and PH was increased (P = 0.015). The most common complication of CBP was thrombocytopenia, and univariate analysis identi ed no risk factors for CBP-related death.
ConclusionCBP can e ciently maintain hemodynamic stability, improve renal function, and has good safety in neonates with septic shock and AKI. However, the mortality remains high, and whether CBP improves the prognosis of neonates with septic shock and AKI remains unclear.
What is Known• Over 50% of children with septic shock was complicated with severe AKI, of which 21.6% required CBP.• The clinical application of CBP in septic shock has attracted increasing attention.What is New:• CBP can e ciently maintain hemodynamic stability, improve renal function, and has good safety in neonates with septic shock and AKI.• The mortality of neonates with septic shock and AKI receiving CBP remains high.
