RESUMO
<p><b>OBJECTIVE</b>To investigate the clinical characteristics of acute arsenic poisoning and its influential factors.</p><p><b>METHODS</b>Clinical data of 47 cases of arsenic poisoning were collected and analyzed. Two cases of observation, 40 cases of mild acute poisoning, and 5 severe acute poisoning were investigated in this group.</p><p><b>RESULTS</b>Myocardial enzyme activity was correlated with age and urine arsenic concentrations. Myocardial enzyme, the liver ALT, total bilirubin (TBil) and indirect bilirubin (IBil) were negatively correlated with vomiting frequency, with statistical significance (P < 0.05). Urine arsenic concentration was correlated with vomiting frequency and amount of soup drunk, with statistically significant difference (P < 0.05). Despite no statistical significance in age and amount of soup drunk, the patients with more vomiting or diarrhea had less urine arsenic concentrations, cardiac enzymes and liver enzyme concentration.</p><p><b>CONCLUSION</b>Acute arsenic poisoning can lead to multiple organ damage. The damage is relevant with amount of arsenic intake, vomiting, diarrhea and urinary frequency arsenic concentration. So early use of gastric lavage, vomiting, poison discharges, and adequate application of effective antidote (Na-DMPS) as soon as possible, symptomatic treatment and the reinforced monitoring, are the rescue key for patients with acute arsenic poisoning.</p>
