Abstract

Hemodialysis by means of an artificial kidney has become a well-established adjunct in maintaining life and reducing morbidity during the oliguric phase of reversible renal failure.1 Some kidney units such as that developed by Skeggs and co-workers2 and Kolff and Watschinger3 utilize a pump to propel the patient's blood through the dialyzing tubing. This modification permits venous blood to be utilized for outflow to the artificial kidney. A pump or negative pressure surrounding the dialyzing membrane4 incorporates ultrafiltration into the procedure of hemodialysis, making possible the reduction of otherwise intractable edema.5

Hemodialysis is time consuming. This factor limits to some extent the availability of the procedure. The period of actual dialyzation with presently available methods cannot be appreciably reduced. It is doubtful whether more rapid rates of clearance are physiologically desirable. However, any time that may be saved in preparing the instrument or the patient
