Charcoal hemoperfusion for chronic renal failure.

16 patients with end-stage renal disease were treated with a fixed-bed, uncoated-charcoal hemoperfusion device, used either alone or in series with a hemodialyzer. 3 patients had one of their thrice weekly dialyses replaced by one 3 hour combined treatment for up to 6 months, and 3 patients had 150-min combined treatments thrice weekly for up to 5 months. The procedure was well tolerated. Transient hypotension occurred and interfered with fluid removal by ultrafiltration. Platelet counts were reduced, but there was no clinical bleeding. Pretreatment of the device with albumin provided no advantage over heparinized saline, and dextran caused a more severe reduction in the platelet count. The changes in platelets, white blood cells, and hematocrit were transient and noncumulative. Considerable amounts of creatinine and uric acid were removed. Regular charcoal hemoperfusion appears to be safe, and long-term studies of clinical efficacy are indicated.
