Buffering Solution

Most dialysate solutions contain lactate as a buffer, as this results in a stable solution.  Lactate is then metabolized to bicarbonate in the liver.  Commonly therefore patients on CVVHDF will have moderately elevated lactate levels.  In the context of a stable patient (unchanged or improving whole blood pH) this should not cause alarm.‚Äč
