Title: Risk factors of severe outcome in acute salicylate poisoning<br/>Author: Hong Kim<br/><a href='http://umem.org/profiles/faculty/526/'>[Click to email author]</a><hr/><p>
A small retrospective study of an acute poisoning cohort attempted to identify risk factors for severe outcome in salicylate poisoning.</p>
<p>
Severe outcomes were defined as</p>
<ol>
<li>
Acidemia pH < 7.3 or bicarbonate < 16 mEq/L</li>
<li>
Hemodialysis</li>
<li>
Death</li>
</ol>
<p>
A multivariate analysis of 48 patients showed that older age and increased respiratory rate were independent predictors of severe outcomes when adjusted for salicylate level.</p>
<p>
Initial salicylate acid level was not predictive of severe outcome. </p>
<p>
Elevated lactic acid level was also a good predictor of severe outcome in univariate analysis but not in multivariate analysis.</p>
<p>
Limitations</p>
<ol>
<li>
Small sample size with single center study</li>
<li>
Retrospective study design</li>
<li>
Validation study of these predictors is needed.</li>
</ol>
<p>
</p>
<p>
<strong>Bottom line</strong></p>
<ol>
<li>
Older age and increases respiratory rate is associated with severe outcome (acidemia, hemodialysis or/and death) in this study.</li>
<li>
Data must be interpreted with caution due to small sample and retrospective study design.</li>
</ol>
