Abel, Rowntree, and Turner “dialyzed” anesthetized animals by directing their blood outside the body and through tubes of semipermeable membranes made from Collodion, a material based on cellulose. The first historical description of this type of procedure was published in 1913.

Today hemodialysis describes an extracorporeal procedure, or procedure outside the body, for filtering uremic substances from the blood of patients suffering from kidney disease. The first scientific descriptions of these procedures dates back to the 19 th century and came from the Scottish chemist Thomas Graham, who became known as the “Father of Dialysis.” At first, osmosis and dialysis became popular as methods used in chemical laboratories that allowed the separation of dissolved substances or the removal of water from solutions through semipermeable membranes.įar ahead of his time, Graham indicated in his work the potential uses of these procedures in medicine. Current procedures for the treatment of kidney failure include physical processes such as osmosis and diffusion, which are widespread in nature and assist in the transport of water and dissolved substances. In early Rome and later in the Middle Ages, treatments for uremia included the use of hot baths, sweating therapies, bloodletting, and enemas.
