Title: Utility of lactic acid level for diagnosis of cyanide poisoning in smoke inhalation victims<br/>Author: Hong Kim<br/><a href='http://umem.org/profiles/faculty/526/'>[Click to email author]</a><hr/><p>
Smoke inhalation victims (house fires) are at risk of carbon monoxide (CO) and cyanide poisoning (CN). CO exposure/poisoning can be readily evaluated by CO - Oximetry but CN level can be obtained in majority of the hospital.</p>
<p>
Lactic acid level is often sent to evaluate for CN poisoning.</p>
<p>
</p>
<p>
Bottom line:</p>
<ol>
<li>
Lactatic acid levels should be sent in all smoke inhalation victims.</li>
<li>
Elevate lactate > 10 mmol/L is highly suggestive of CN poisoning<br type="_moz" />
.</li>
</ol>
