We have investigated the efficacy of a pumpless hemoperfusion technique, continuous arteriovenous hemoperfusion (CAVHP) in 3 cases of acute intoxications with meprobamate, theophylline and phenobarbital. Dramatic responses were noted in both hemodynamic unstable and comatous patients. With this technique, a blood flow of 120cm3/ min could be achieved in severe hypotension. Moreover, with the restoration of blood pressure, blood flow increased to 150-400 cm3/ min. Our preliminary experience has shown that CAVHP allows an exceptionally high solute elimination. Hemoperfusion clearances of meprobamate, phenobarbital and theophylline were 198 ± 5.6 cm3/min, 290.25 ± 25.33 cm3/ min and 192.79 ± 55 cm3/ min, respectively. Our present results suggest that CAVHP is a simple, safe, effective and less costly alterative of conventional hemoperfusion.
