What’s the optimal dose of continuous renal replacement therapy? The Australasian RENAL investigators compared 25ml/kg/hr vs 40ml/kg/hr (effluent flow) of post-dilution continuous venovenous haemodiafiltration in over 1500 intensive care patients. There was no difference in 90 day mortality or renal recovery, but the high intensity group had significantly more hypophosphataemia.
