Incidental Aluminum Phosphide Poisoning: Case Report and Current Management

: Aluminum phosphide (AlP) is a commonly used cheap rodenticide, insecticide, and fumigant. Most intoxications in the literature are suicidal ingestions, however, AlP may cause incidental inhalational toxicities as well. After ingestion or inhalation, nausea, vomiting, dyspnea and abdominal pain develops within minutes. Hallmark of toxicity is refractory hypotension, cardiac failure and severe metabolic acidosis developing within a matter of hours are the major cause of mortality. In Turkey, AlP tablets are widely accessible and are sold without any restrictions. However, there are few local case reports in the literature. Additionally, incidental AlP intoxications are rarely reported. Herein, we present a 25-year-old male patient incidentally poisoned with AlP. He was found unconscious in a grain storage unit protected by aluminum phosphide tablets. He had hypotension and tachycardia. Arterial blood gas analysis did not reveal metabolic acidosis. He was quickly intubated and admitted to Intensive Care Unit (ICU). Supportive care crystalloid solution, n-acetyl cysteine and norepinephrine infusion was administered. After 36 hours, he was extubated and discharged without any complications. There is no specific antidote or treatment for AlP toxicity. Literature is controversial regarding treatment approach. Inhalational toxicity may occur under extreme conditions, as presented in this case report. Preventive strategies should be considered to reduce incidents. Clinicians should also be aware that AlP is a widely available and highly toxic compound that has no specific antidote and toxicity needs to be urgently treated with best supportive care.
