ANESTHETIC CONSIDERATIONS FOR THE PATIENT WITH RENAL FAILURE

The blood urea nitrogen (BUN) itself probably does not cause all the manifesta- tions of the syndrome known as uremia, and may be elevated independently of renal failure. Nonetheless it serves as a marker for the basic pathophysiologic

clinical and pathological differences were due to the disease being observed at different stages. This lengthy and futile debate is well described by J. Bleker . Around 1890 the dilemma of what was known as dissociated renal impermeability, that is, edema without clinical uremia versus clinical uremia without edema remained unsolved. Con-

Oral manifestations in chronic uremia patients

The clinical manifestations of acute renal failure (ARF) do not differ in kind from those seen in chronic renal failure (CRF), but tend to be more severe, occur at lower levels of BUN, and in a more fulminant manner. The neurologic manifesta tions of uremia are generally similar whatever the
