Continous infusion of nor adrenaline + albumin Continous infusion of terlipressin + albumin Response will assessed at every 48 hour (i) Complete response: Regression of acute kidney injury stage with reduction of S. Cr within 0.3 mg/dl of baseline (ii) Partial response: Regression of acute kidney injury stage with reduction of S. Cr to ≥0.3 mg/dl above baseline (iii) No response: No regression of acute kidney injury

If intolerant to terlipressin, excluded from study and rescue treatment will be given in form of noradrenaline or octreotide and midodrine.
