[Successful hemodialysis for life-threatening carbamazepine drug overdose: Case-based introduction of new guidelines].

BACKGROUND: Over the last decade, there has been a paradigm shift in the extracorporeal treatment of intoxications. The availability of new treatment options, especially new membranes has led to a decrease in the use of techniques like charcoal hemoperfusion, once considered the gold standard to eliminate highly protein bound substances. EXTRIP GUIDELINES: The EXtracorporeal Treatments In Poisoning (EXTRIP) workgroup is a collaborative international effort of pharmacologists, toxicologists, critical care physicians, and nephrologists that is reviewing all available evidence in extracorporeal procedures for the treatment of poisonings in a standardized way to distill treatment recommendations for the physician at the bedside. One of the first available EXTRIP guidelines summarizes treatment recommendations for severe carbamazepine intoxications. CASE REPORT: We report the case of a 43-year-old Caucasian woman with who ingested about 21 g carbamazepine in a suicidal attempt together with alcohol. Combining gastroscopic removal of carbamazepine and multiple dose activated charcoal with intermittent high-flux hemodialysis lowered the initial carbamazepine level of 56.5 mg/l (47 mg/l before dialysis) to 25 mg/l. The patient, who initially required mechanical ventilation could be transferred to the psychiatric ward 24 h after ICU admission.
