The role of plasmapheresis in organophosphate poisoning: Case reports of three pediatric patients.

The aim of the study was to assess the impact of plasmapheresis treatment in the management of three pediatric patients with organophosphate poisoning who did not respond to standard treatment. The treatment of signs and symptoms, and supportive treatment has been evaluated in this paper. Patients were initially given atropine infusion and 0.05 mg/kg atropine with five-minute intervals. Despite pralidoxime loading and three consecutively infusions clinical symptoms did not respond to the treatment and plasma pseudocholinesterase levels did not decrease. At this point, plasmapheresis was used on three consecutive days. Accordingly, the clinical signs improved and mechanical ventilation was no longer necessary. Patients were discharged on the sixteenth day after their admission to the hospital. Plasmapheresis may be an option for the patients who do not respond to atropine and pralidoxime treatment in organophosphate poisoning.
