Severe reactions to Cuprophan capillary dialyzers.

Five severe reactions occurred in four maintenance hemodialysis patients 1 to 5 minutes after initiating dialysis with Cuprophan capillary dialyzers. All reactions were life-threatening and one resulted in death. Inadequate rinsing of the dialyzers was probably the cause of the reactions. The severe reactions were managed by immediate discontinuation of dialysis and the institution of supportive treatment. Antianaphylactic measures were also attempted, but their therapeutic effectiveness remains to be determined.

Hematologic studies during isolated ultrafiltration.

The effect of negative-pressure isolated ultrafiltration on leucocytes, platelets, and clotting factors was evaluated in maintenance hemodialysis patients. A significant decrease in the number of leucocytes was observed during the first 45 minutes of ultrafiltration. However, by one hour, leucocyte counts had returned to pre-ultrafiltration values. A slight, of haptoglobin, free hemoglobin, or fibrinogen after one hour of isolated ultrafiltration. Levels of fibrin degradation products and fibrin monomers similarly showed no change. Heparin administration alone had no effect on the above hematologic values. We suggest that isolated ultrafiltration, as clinically practised, has little acute effect on the coagulation system, and does not cause detectable hemolysis. The transient decrease in leucocyte count, and the modest fall in platelet count that were found are in keeping with changes previously reported to occur during hemodialysis.

Treatment of uremic pericardial effusion by local steroid instillation via subxiphoid pericardiotomy.

Seven maintenance hemodialysis patients suffering from intractable uremic pericardial effusion were treated with instillation of a non-absorbable steroid, triamcinolone hexacetonide, into the pericardial sac via a large-bore catheter. The latter was placed under direct vision by subxiphoid pericardiotomy. All patients responded to the treatment while complications of the procedure were few and minor.

Isolated ultrafiltration in the treatment of dialysis ascites.

Three patients with dialysis ascites improved markedly after treatment with isolated ultrafiltrations. This simple, noninvasive technique should be applied first to patients with dialysis ascites before resorting to more drastic therapeutic measures.
