Acute venous hemodialysis using the unipuncture apparatus.

Hemodialysis is a well recognized treatment modality for the support of patients with acute renal failure. In such patients, rapid access to the circulation for hemodialysis is important. For those patients with self-limited acute renal failure in whom recovery is expected, a rapid means of gaining temporary access to the circulation would be particularly desirable. The Seldinger technic for femoral vein catheterization and the use of the unipuncture dialysis apparatus have been combined to meet this requirement. The efficiency of unipuncture dialysis through a single femoral catheter compares favorably with the efficiency of dialysis by the standard two catheter technic.
