Primary and secondary detoxification in severe flecainide intoxication.
Since experience with primary and secondary detoxification in severe flecainide intoxications is limited, 2 different cases of flecainide intoxications are reported. In the first case, with plasma concentrations of 6500 ng/ml (therapeutic range: 200-980 ng/ml), the patient survived with a pacemaker and catecholamine support. In the second case, hemoperfusion terminated the need for emergency resuscitation during the initial phase, but was unsuccessful 3 h later. Even with a lower plasma concentration the patient died. Both patients had rapid onset of symptoms due to the very good bioavailability of the drug. Although it may be a rare intoxication, it is dangerous because of its quick onset and its efficiency in altering the cardiac stability. We recommend the prophylactic use of a pacemaker and gastric suction. The usefulness of hemoperfusion has not yet been proven.
