RESUMEN
<p><b>OBJECTIVE</b>To explore the effect of hemoperfusion (HP) on tylenol poisoned patients.</p><p><b>METHODS</b>Urgently established the blood access by transfemoral catheterization of femoral vein, we used charcoal hemoperfusion by blood pump and dynamically monitored the plasma concentration of tylenol active ingredients for the 2 patients and the content of tylenol active ingredients in the charcoal was determined.</p><p><b>RESULTS</b>Plasma concentration of tylenol active ingredients of the 2 patients was declined gradually during and after the HP management. The acetaminophen serum concentration of the case 1 was declined from the 13.4 µg/L at the start of HP to the 5.81 µg/L at the end of HP; and the case 2 was declined from 51.1 µg/L to 22.3 µg/L. The adsorption amount of acetaminophen in the blood perfusion device are respectively 119 542 µg of case 1 and 33 2154 µg of case 2.</p><p><b>CONCLUSION</b>Early hemoperfusion should be carried out for acute tylenol poisoning patients if there were indications, hemoperfusion can clear the tylenol active ingredients and this is an effective measure to eliminate tylenol active ingredients.</p>
