Abstract

We have found that charcoal hemoperfusion is effective in removing bromvalerylurea (BVU) from circulation. A patient poisoned with BVU showed a marked lightening of coma after 3 h of hemoperfusion. The BVU concentration in the patient's serum was decreased significantly by hemoperfusion. In an experiment with dogs without hemoperfusion, the BVU concentration had its peak at the fourth hour after oral administration and decreased in 24 h. In an experiment with hemoperfusion, BVU concentration in dogs decreased markedly during hemoperfusion. After hemoperfusion a rebound of concentration was observed.
