Abstract
Background: Organophosphates (OP) compounds are used as insecticides in agricultural and domestic settings throughout the world. Acute pesticide poisoning has a high morbidity and mortality, especially in developing countries. The purpose of this study was to evaluate the data on acute adult organophosphate poisoning (OPP).
Methods: In Descriptive cross sectional study at Loghman Hakim Hospital in Tehran-Iran during March 2010 to June 2013 and identify the risk factors of mortality, patients with the primary diagnosis of OPP who were admitted to Loghman-Hakim Hospital Poison Centre (LHHPC) were the subjects of this prospective study. Cholinesterase (CE) activity and the PR interval was determined for each patient using the Bazett formula and considering >200 msec. as prolonged. Comparative outcomes of the study were respiratory failure, systolic blood pressure, GCS and intentional poisoning, analysis of the PR interval in the primary ECG on admission, and rate of mortality.
Results: The study included 201 patients with a diagnosis of OPP. The mean age of the patients was 33.93. The mortality rate was 9%. Nine patients had conductive abnormality (PR prolongation) in ECG. There was no significant difference between two groups (prolonged and normal PR intervals) according to respiratory failure and systolic blood pressure<90mm Hg and GCS and intentional poisoning. The mortality rate in the long PR group was significantly higher than that of the normal PR group.
Conclusion: In our study it has been well demonstrated that PR-interval prolongation affects mortality rate. Prolongation of the PR interval is associated with increased risks of mortality in OPP.
