AbstractPorphyrias are a group of rare, mostly inherited metabolic disorders of heme biosynthesis. Each type of porphyria results from a specific deficiency of one of the pathway enzymes, causing a characteristic accumulation and excretion of heme precursors. Diagnosis is confirmed by the biochemical detection of these porphyrins and the precursors in urine, feces and blood. Porphyrias can be classified into acute and non-acute forms. The clinical presentation is unspecific and includes acute neurovisceral and/or cutaneous symptoms. The latent phase can evolve into a potentially life-threatening acute crisis, which is often misdiagnosed. The four acute hepatic porphyrias are relevant for anesthesiologists as precipitating factors are commonly found in the perioperative setting. Safe anesthetic management in cases of known porphyria is possible by adherence to current recommendations. The immediate administration of heme arginate as specific treatment for acute attacks is decisive for the outcome.© 2022.
