ABSTRACT
INTRODUCTION: Aluminium phosphide (Alp) poisoning mortality rate has been reported as high as 70-100%, and refractory hypotension and cardiogenic shock are the two most common presentations leading to death. Due to lack of specific antidote, all treatments are focused on supportive care and recently, intra-aortic balloon pump (IABP) has been suggested to treat cardiogenic shock resulting from toxic myocarditis. In the current paper, we introduce three Alp poisoned patients for whom IABP was applied to manage their refractory shock. CASE PRESENTATION: Two men and one woman who were admitted to emergency department (ED) of Imam Reza academic Hospital, Mashhad, Iran due to intentional Alp poisoning are reported. The cases visited the ED shortly after ingestion and nearly all of them showed hypotension, tachycardia and metabolic acidosis during early hospitalization. Due to persistent shock state, despite receiving intravenous fluid therapy and vasopressor agents, IABP insertion was performed in these cases. Finally, one of them survived and the other two died. CONCLUSION: It still cannot be decided whether IABP insertion is effective in cases of Alp poisoning or not. It might be reasonable to try this intervention along with other conservative treatments in patients who survive more than 12 hours and consistently suffer from refractory hypotension.
ABSTRACT
BACKGROUNDS AND AIMS: Acute kidney injury (AKI) is a frequent event after congenital heart surgery with increased mortality and morbidity. We investigated frequency, risk factors, and associated morbidity and mortality of AKI after pediatric cardiac surgery at a single institution. METHODS: Children undergoing congenital heart surgery from March 2013 to February 2016 were assessed for development of AKI based on modified pediatric Risk, Injury, Failure, Loss, and End-stage renal disease criteria. They were also investigated for predictive risk factors, associated mortality, and morbidity including duration of mechanical ventilation, Intensive Care Unit (ICU), and hospital length of stay. RESULTS: Five hundred and nineteen patients were recruited during the study period including 259 (49.9%) males and 260 (50.1%) females. AKI was seen in 150 (28.9%) patients including 101 (67.3%), 42 (28%), and 7 (4.7%) cases with risk, injury, and failure stages, respectively. Patients with AKI had longer ventilation time (P = 0.002), ICU (P = 0.05), and hospital (P = 0.56) stay. Mortality was seen in 31 (2.7%) and 44 (11.9%) patients with and without AKI, respectively (P = 0.01). After multivariable logistic regression, there was an association between AKI and preoperative abnormal levels of creatinine (adjusted odds ratio [aOR] = 0.47, 95% confidence interval [CI] 0.22-1.01; P = 0.05), presence of cyanotic heart disease (aOR = 1.97, 95% CI = 1.15-3.2; P = 0.01), duration of surgery (aOR = 1.05/10 min, 95% CI = 1.01-1.08; P = 0.007), and elevated lactate level (aOR = 1.14, 95% CI = 1.03-1.3; P = 0.01). CONCLUSION: The presence of cyanotic heart disease, duration of surgery, elevated postoperative lactate level, and likely preoperative creatinine level were independent risk factors for the development of AKI after congenital heart surgery.
