Aluminium release from the Sorbsystem D-3160 and D-3260 cartridges.
Recent clinical information indicates that the aluminium level of patients' serum can rise while they are being treated with the Sorbsystem haemodialysis system. Further evidence suggests that the quality of aluminium removed from the dialysing fluid by the sorbent cartridge utilized in this equipment is time-dependent. Evaluation of the sorbent cartridges D-3160 and D-3260 has shown that ultimately aluminium is satisfactorily removed from the dialysing fluid. However, the time taken to achieve the safe condition of less than 30 micrograms/litre of aluminium is dependent on the quantity of aluminium washed out from a new cartridge before being reabsorbed, and the highly variable quantity contained in the diluting water. The results have also shown that the level of aluminium recommended by the DHSS in April 1982 (30 micrograms/litre) is not reliably attained following the manufacturer's recommended pretreatment, and a further 60 min of operation in the 'dialyse' mode is necessary. It should be noted that, as a result of evaluation of the Sorbsystem, the DHSS have issued guidelines on the use of this equipment.
