From Sphygmomanometer to Lungs: Unveiling Mercury Poisoning in Emergency Department.

ABSTRACT

Mercury, a ubiquitous heavy metal, poses a significant threat to human health. Intravenous mercury poisoning is an uncommon but critical medical emergency. The nature and severity of its toxic effects depend on the form of mercury encountered elemental, inorganic, or organic. It can affect almost all organ systems in the body. Chelating agents are the primary treatment for symptomatic mercury poisoning. This case report is about a 27-year-old male patient who presented to the emergency department with an alleged history of intravenous injection of mercury as an attempt at suicide, followed by breathlessness, chest pain, vomiting, and high-grade fever. He was managed with chelating therapy, non-invasive ventilation, and other supportive measures and was discharged home. After five days of discharge, he presented with fever and rashes and was diagnosed with toxic epidermal necrolysis (TEN). In spite of all aggressive management, he succumbed to death after four days of re-admission. Early intervention can significantly improve the chances of recovery. However, even with successful treatment, some individuals may experience long-term complications.
