The Comparative Effectiveness of Alprostadil,Sodium Ferulate and Dopamine in Pediatric Acute Kidney Injury

Acute kidney injury (AKI) is a pervasive clinical event in children.It has been independently associated with prolonged hospital stays, risk of in-hospital death and future progression to chronic kidney disease. Except for removal of nephrotoxic agents and optimization of supportive care,there are still no other effective therapeutic options recommended by recent guidelines. Renal ischemia is the main mechanism of AKI, the improving microcirculation therapy would be the effective management to improve the outcome of AKI in children. Dopamine is a vasodilating drug that in small doses improves renal circulation. Alprostadil have been used in chronic arterial occlusion and Sodium Ferulate in ischemic cerebral vascular disease,they have a similar therapeutic effect of anti-platelet aggregation and vasodilation. Recent research shows that alprostadil might be associated with a significant reduction in postcontrast Scr, blood urine nitrogen (BUN) and Cystatin C (CysC) level and decrease the incidence of contrast-induced nephropathy.The investigators speculate that Alprostadil,Sodium Ferulate and dopamine would be effective in treating AKI in children. This is a prospective, multicenter, randomized, double-blind, 52-week study. The purpose of this study is to evaluate the comparative effectiveness and safety of Alprostadil,Sodium Ferulate and dopamine in improving the outcome of AKI in children.
