Time-Dependent Changes Of Hematological Parameters In Patients With Acute Organophosphate Poisoning

Objective: To investigate the prognostic value of the time-dependent changes of hematological parameters in patients with acute organophosphate poisoning. Methods: All patients admitted to emergency departments from 2010 through 2013 due to organophosphate poisoning were enrolled in the study. Demographic data, route of exposure, serum cholinesterase levels, complete blood count results of 5 consecutive days, mechanical ventilation requirement, length of stay in hospital, and outcomes were recorded. Results: Mechanically ventilated patients had higher leukocyte and neutrophil counts than nonventilated patients during the whole follow-up period, and both of them had a trend of decrease in both patient groups. There was no difference between patient groups in terms of lymphocyte counts at day 1, but mechanically ventilated patients had lower lymphocyte counts than nonventilated patients after day 2. Hemoglobin levels had a trend of decrease during the whole follow-up period in both patient groups. Conclusion: The parameters obtained from complete blood count can be used as sensitive follow-up parameters in patients with acute organophosphate poisoning by serial measurement
