Introduction: Organophosphate poisoning being most common poisoning in Indian scenario, requires a watchful and emergency diagnosis and management. It requires certain parameters which can help a clinician. Various parameters were studied but here we studied random blood sugar level at presentation as prognostic indicator. Aims and objective: To study the clinical presentation, severity & outcome in OPC poisoning patients and to correlate random blood sugar level with various parameters. Methodology: This is cross sectional study conducted in JLN Medical College and hospital, Ajmer during year 2016–2017 including 100 patients. Results: Random blood sugar level at the time of presentation was statistically significantly correlated with fasciculation (<0.0001), respiratory failure (<0.0001), WHO seriousness grade (0.001), duration of hospital stay (0.0047), ventilator requirement (<0.0001) and outcome (0.0001). Conclusion: India as a developing country has many OPC poisoning patient deaths every year. As a prognostic marker RBS can be used as a simple, easily available & cheap method to asses severity and prognosis.
