Inadequate removal of methanol and formate using the sorbent based regeneration hemodialysis delivery system.

The sorbent based hemodialysis delivery system was shown to be ineffective for the treatment of methanol intoxication. Clinical and in vitro studies showed rapid saturation of the sorbent cartridge for methanol and formate adsorption. Methanol and formate clearances were four fold less than achieved with the recirculating single pass delivery system. The sorbent delivery system should not be used for methanol intoxication.
