Effects of Standard Treatment Alone versus Standard Treatment Plus Plasmapheresis on the Levels of Serum Pseudocholinesterase and Erythrocyte Acetyl Cholinesterase in Critically Patients with Organophosphate Poisoning: Randomized Controlled, Open-Label, ClinicalTrial.

Objective: Organophosphates are the insecticides commonly used worldwide. Inadequate treatment for organophosphates poisoning increases morbidity, and mortality. Purpose of the work was to determine the effect of standard treatment alone versus standard treatment plus plasmapheresis on the levels of serum pseudo-cholinesterase, and erythrocyte acetyl cholinesterase in severe patients with organophosphates poisoning. Material and Method: This research is a prospective study. Patients diagnosed with organophosphates poisoning were included in the work. The patients were divided into two groups as the intervention group, and the standard group. The intervention group, plasmapheresis was performed in addition to the standard treatment. Results: The research was conducted with forty cases. (Intervention group n=21, standard group n=19). Serum pseudo-cholinesterase values were 482.5 u/L at baseline, 3723 u/L after plasmapheresis. Erythrocyte acetyl cholinesterase values were 1.91 u/mL on admission, 2.53 u/mL after plasmapheresis. Erythrocyte acetyl cholinesterase and serum pseudo-cholinesterase values were compared between the two groups daily from the admission of patients to intensive care units during the first 5 days, and on the last day in the intensive care units. There was no statistical difference between two groups (p> 0.05), except for the second day. It was observed that there was a statistically significant difference between the pseudo-cholinesterase values in the second day comparison of both groups (p=0.028). Conclusion: In conclusion, plasmapheresis treatment may contribute positively to pseudo-cholinesterase level. This treatment may have provided additional time for the organophosphates to be eliminated from the body. Although acetyl cholinesterase reactivation is achieved with oxime treatment, the clinical effect of this treatment is not clear. [ABSTRACT FROM AUTHOR]
