Impact of extra-corporeal membrane oxygenation on outcome of aluminium phosphide poisoning complicated with myocardial dysfunction
2019
AbstractBackground: Aluminium phosphide (AlP) poisoning is associated with a high mortality rate when patients are complicated with myocardial dysfunction and refractory shock or severe metabolic acidosis. We studied the role of veno-arterial extra-corporeal membrane oxygenation (VA-ECMO) in patients of AlP poisoning induced myocardial dysfunction.Methods and results: This is a tertiary care, single-centre, retrospective study. Between January 2011 and June 2016, total of 107 patients with AlP poisoning were identified and of those 67 were categorised in high-risk category as per the criteria. The in-hospital mortality of patients who received ECMO (n = 35) was compared to those who received conventional treatment (n = 32) only. The use of ECMO in addition to conventional treatment has reduced the in-hospital mortality from 84.4% to 40% (odds ratio: 0.47; 95% confidence interval 0.31–0.73). Among survivors, the ECMO group had a significantly lower baseline left ventricular ejection fraction (LVEF; median:...
