RESULTS IN PATIENTS TREATED WITH THE COIL KIDNEY (DISPOSABLE DIALYZING UNIT)

JAMA. 1956;161(15):1433-1437. doi:10.1001/jama.1956.02970150001001
Abstract

• A disposable type of artificial kidney, a dialyzing unit consisting of twin coils of cellulose tubing, was used in eight patients. The biochemical details of 11 dialyses are given to show the reduction of blood urea thus achieved, and the clinical effects are illustrated in a table and in three case histories. In one patient a total of 50 gm. of urea was removed at one session and 66 gm. at a later time.

The device here described has a dialyzing area of 18,000 sq. cm. and gives a urea clearance of about 140 ml. per minute. It has an advantage over some other forms of artificial kidney in being disposable; this eliminates certain problems of cleaning, sterilizing, and setting up. The temporary improvement in some patients and complete recovery in others demonstrated the lifesaving possibilities of this apparatus.
