Successfully managed aluminum phosphide poisoning: A case report.

INTRODUCTION

and

Importance

Aluminum phosphide (ALP) is a commonly available pesticide in agricultural countries like Nepal. Upon ingestion, this releases highly toxic phosphine gas in the gastrointestinal tract when it comes in contact with humidity. This leads to refractory shock, metabolic acidosis, cardiac arrhythmia, renal failure, and hepato-biliary impairment.

CASE PRESENTATION: We present a successfully managed case of a 17-year-old girl who ingested 6 g (2 tablets) of ALP tablets with suicidal intent. Although the mortality has been reported as 70-100% with mere ingestion of 150-500 mg of ALP, this case survived even after developing severe metabolic acidosis, acute renal failure, refractory shock, and ventricular tachycardia.

CLINICAL DISCUSSION: ALP poisoning is most often lethal. However, there is an emerging evidence of successful use of various drugs such as magnesium sulfate, trimetazidine, and other interventions such as intra-aortic balloon pump and extra corporeal membrane oxygenation in case of ALP poisoning.

CONCLUSION

Owing to the unavailability of an effective antidote of ALP to date, we emphasize early initiation of supportive management, intensive monitoring, and potential role of membrane stabilizers like magnesium sulfate, and cardio-protective agents like trimetazidine, N-Acetyl cysteine, thiamine, vitamin C, and hydrocortisone in decreasing the likelihood of fatal outcome.
