Abstract

Objectives: Organophosphorus compound (OPC) poisoning is primarily a problem in developing countries. Its widespread use and easy availability have increased the likelihood of poisoning with these compounds. Serum cholinesterase levels are easier to estimate and usually depressed after organophosphorus (OP) poisoning. Peradeniya OP poisoning scale has not been studied much in the Indian scenario. It could be a simple and effective system to determine the need for ventilatory support early on in the course. Hence, this study was undertaken to assess the severity of OPC poisoning clinically using Peradeniya scoring and by estimating creatine phosphokinase (CPK) and lactate dehydrogenase (LDH) levels. Material and Methods: A prospective observational study was performed among 100 cases of OP poisoning from January 2021 to October 2022. On patient’s fulling, inclusion criteria were investigated with serum acetylcholinesterase at the time of admission, and periodic estimation of serum CPK and serum LDH was done on the day of admission and then on day three and day 5 of admission Results: The CPK and LDH levels were significantly elevated in patients who developed respiratory failure and thus strongly correlated with clinical severity Conclusion: Serum CPK and LDH show a strong degree of positive correlation with the severity of poisoning and can be used as a predictor of outcome in OP poisoning.
