Acute Kidney Injury With Cirrhosis
Conditions
Brief summary
Intervention: All patients at presentation would be assessed for the underlying cause of and will be managed by removal of all precipitants(careful review of medications, diuretics, nephrotoxic drugs,vasodilators or non-steroidal anti-inflammatory drugs). The second step would be to consider plasma volume expansion in patients with hypovolemia (the choice of fluid could either be a crystalloid or albumin or even blood as indicated) along with identification and early treatment of bacterial infections. Along with this patients with a differential diagnosis of HRS-AKI would be given terlipressin ( or noradrenaline/octreotide midodrine in case of contraindication to terlipressin). Patients with a clinical diagnosis of ATN would be randomized to the on-demand versus protocol-guided dialysis groups. Further, patients with urine output of less than 0.5ml/kg/hour for 4-6 hours despite adequate fluid resuscitation and vasoconstrictors would also be subjected to randomization. 1. In the on-demand group patients would get dialysis only when patient fulfills absolute criteria requiring dialysis such as metabolic acidosis with ph\<7.2, hyperkalemia, refractory fluid overload (non-responsive to diuretics) or oliguria with urine output of less than 0.5ml/kg for more than 24-48 hours from the time of randomization 2. In the protocol guided group patients all patients would be considered for dialysis within 6 hours of randomization After randomization patients would receive dialysis as three sessions per week of at least 4 h with a blood flow \>200 mL/min and a dialysate flow \>500 mL/min in intermittent group and as 20-25 mL/kg/h of effluent, by filtration and/or diffusion in continuous form until recovery of renal functions
