RESUMEN
Organophosphorous (OP) poisoning is an ever increasing and troublesome situation in the developing countries and is a major health care challenge in the 21st century. Hundred patients who attempted suicide with organophosphates, admitted to the emergency services were included in the study. They were graded (grade 0,1,2,3) according to clinical findings and examined for parameters like RBS, serum urea, serum creatinine, liver function tests, serum amylase, serum cholinesterase and LDH . The APACHE (II) of the cases were determined and correlated with severity of the clinical manifestations. A significant decline in serum cholinesterase (ChE) with increasing grades of intoxication(p <0.05) was observed along with raised levels of random blood sugar, serum urea, creatinine, hepatic enzymes and amylase. APACHE(II) score, showed a significant rise with severity of the degree of intoxication (p<0.001) and a negative correlation with serum cholinesterase. The findings of this study highlighted usefulness of biochemical and clinical indices in the management of organophosphorous poisoning thereby recognizing the complications early and facilitating early management.
