Severe Glyphosate Intoxication with a Laryngopharyngeal Corrosive Injury

ABSTRACT

Glyphosate is an herbicide that is used worldwide. Suicidal attempts with a glyphosate-surfactant herbicides (GlySH) are on the rise. The severity of corrosive injuries is thought to have a close correlation with a higher complication rate or pulmonary aspiration. We report a case with multiple toxic effects associated with a severe laryngopharyngeal corrosive injury following GlySH intoxciation. Specifically, a severe laryngopharyngeal corrosive injury might be significantly associated with the toxic effects and complications, including respiratory failure and chemical pneumonia, bleeding tendency, increased BUN/Cr ratio, and frequent aspiration due to dysphagia. Appropriate evaluation and management of corrosive injuries may be helpful in caring for GlySH-intoxicated patients.
