Evolution of CRRT ca. 2006 from @croncoIRRIV #Nephpearls #DialysisDirector

CVVHD
📌 Dialysate is passed through the dialysate compartment of the filter continuously and at a slow rate
📌 Diffusion is the primary method of solute removal
📌 Fluid removal: Usually about 3–6 L per day
#Nephpearls #DialysisDirector

CVVH
📌 Dialysate is not used
👉🏼 Large volume (~ 25–50 L/day) of replacement fluid is infused into either inflow or outflow blood line
📌 Convection is the primary method of solute removal
📌 Fluid removed = Replacement fluid + excess fluid removed
#Nephpearls #DialysisDirector

CVVHDF
📌 Dialysate is used
👉🏼 Replacement fluid is infused into either inflow or outflow blood line.
📌 Diffusion and Convection are the methods of solute removal
📌 Fluid removed = Infused Fluid + Net Volume removed
#Nephpearls #DialysisDirector

SCUF
📌 Set-up is similar to that for CVVHD and CVVHDF
📌 Neither dialysate nor replacement fluid is used
📌 Minimal solute removal via convection
📌 Fluid removal: Usually about 3–6 L per day (similar to CVVHD)

SLED
📌 Form of intermittent hemodialysis
📌 Extended (6-10 hours) session length
📌 ⬇️ BFR (200 mL/min)
📌 ⬇️ DFR (100-300 mL/min)
📌 Diffusion is the primary method of solute removal
