Forensic view on aluminium phosphide poisoning.

ABSTRACT

In India, acute aluminium phosphide poisoning (AAlPP) is a serious health care problem. This study aimed to determine the characteristics of AAlPP and the predictors of mortality at the time of patients' admission. We studied consecutive admissions of patients with AAlPP admitted to the intensive care unit (ICU). We noted 38 parameters at admission to the hospital and the ICU and compared survivor and non-survivor groups. A total of 54 patients were enrolled comprising 10 females and 44 males and the mean ingested dose of poison was 0.75 ± 0.745 grams. The mortality from AAlPP was 59.3%. We found the following factors to be associated with an increased risk of mortality a serum creatinine concentration of more than 1.0 mg % (P = 0.01), pH value less than 7.2 (P = 0.014), serum bicarbonate value less than 15 mmol/L (P = 0.048), need for mechanical ventilation (P = 0.045), need for vasoactive drugs like dobutamine (P = 0.027) and nor adrenaline (P = 0.048) AAlPP causes high mortality primarily due to early haemodynamic failure and multi-organ dysfunction.
