RESUMO
<p><b>OBJECTIVE</b>To investigate the factors affecting clinical therapeutic effect on acute tetramine poisoning.</p><p><b>METHODS</b>Using Logistic regression to analyze the relationships among the degree of tetramine poisoning, time of onset, time of admission, exposure history, sex, age, unithol, gastric lavage, etc with the death of poisonded patients.</p><p><b>RESULTS</b>The fatality rate of patient with tetramine poisoning who got gastric lavage was less than that who did not (5.85% vs 38.00%, P < 0.01). In patients who got gastric lavage, the fatality rates were increased with the degree of tetramine poisoning (control: 0%, mild poisoning: 3.07%, severe poisoning: 9.14%, P < 0.05). There was no significant difference in fatality between using unithol and not using patients (7.22% vs 8.25%, P > 0.05).</p><p><b>CONCLUSION</b>Unithol has no significant influence of clinical therapeutic effect on tetramine poisoning patients and dose not reduce the fatality rate of patient with tetramine poisoning, but gastric lavage and the degree of tetramine poisoning do. Logistic regression analysis showed that gastric lavage is the main factor affecting the therapeutic effect on tetramine poisoning.</p>
