Abstract
Poisoning from mercury has the potential to affect multiple organ systems and can be fatal in some circumstances. We present a case of a patient who had both ingested and inhaled elemental mercury resulting in deposits in his pulmonary and gastrointestinal systems. The patient was admitted to the intensive care unit (ICU) as a precautionary measure but did not require any organ support. The patient was treated with chelation therapy guided by the UK National Poisons Information Service (NPIS) and was discharged from ICU after having a prophylactic appendicectomy due to mercury deposition. This case presented several challenges logistically as there was a need to follow expert guidance with regards to personal protective equipment (PPE) and waste disposal, alongside the clinical requirements.
