Glyphosate poisoning - a case report.

Glyphosate is the most commonly used broad-spectrum, non-selective herbicide in the world. The toxicity is supposed to be due to uncoupling of oxidative phosphorylation and the surfactant polyoxyethylene amine (POEA)- mediated cardiotoxicity. Clinical features of this herbicide poisoning are varied, ranging from asymptomatic to even death. There is no antidote and aggressive supportive therapy is the mainstay of treatment for glyphosate poisoning. We present a 69-year-old female patient with suicidal consumption of around 500 ml of Glycel®. Initially, gastric lavage was done and intravenous fluids were given. Within two hours of presentation, the patient developed respiratory distress needing intubation, hypotension needing vasopressor support, and severe lactic acidosis. She also developed acute respiratory distress syndrome, hypokalemia, hypernatremia, and aspiration pneumonia. Our patient was critically ill with multiple poor prognostic factors, but with timely aggressive supportive management, the patient gradually recovered.
