Clinical Profile and Treatment Outcome of Aluminum Phosphide Poisoning in Felege Hiwot Referral Hospital, Northwest Ethiopia: A Retrospective Study.

backgroundAluminum phosphide (AlP) is an effective fumigant and rodenticide which is a commonly used agent for self-poisoning in parts of Ethiopia. AlP poisoning results in serious manifestations involving many vital organs and it has high mortality. Despite its high incidence and mortality, studies on AlP poisoning in Ethiopia are lacking. Our objective was to study the clinical profile and treatment outcome of AlP poisoning in Felege Hiwot Referral Hospital (FHRH), a major referral hospital in Ethiopia.

methodsIt is a retrospective study conducted over all consecutive AlP poisoning cases who presented to the emergency department (ED) of the hospital from March 2018 to August 2020. A questionnaire was used to collect data from patient medical records. All data were analyzed using SPSS 25.

resultsA total of 125 patients were studied. Females were 57.6% and males were 42.4%. Age of patients ranged from 12 to 60 with mean age 28.5 years. The average number of AlP tablets taken was 1.2 (3.6 gm) and the average time of arrival to hospital after AlP ingestion was 4.8 hours. Nausea and vomiting were the commonest presenting features seen in 74.4% of the cases followed by hypotension which was seen in half of the cases. A wide range of laboratory findings and complications were also observed. Cases of AlP poisoning with hypotension were managed in the ICU with dopamine infusion, magnesium sulphate, hydrocortisone, and calcium gluconate in addition to gastric lavage and fluid administration. Those cases without hypotension were managed with gastric lavage and maintenance fluid only. Overall mortality from AlP poisoning was 31.2%.

conclusionWith a treatment protocol used in FHRH, mortality from AlP poisoning was 31.2%. Using this protocol in resource limited settings might give opportunities to reduce mortality from AlP poisoning.
