title: [Anesthesia and porphyria].
abstract: The porphyrias are a group of disorders of haem metabolism. A knowledge of which anaesthetic can precipitate an acute attack of porphyria is important, since an accumulation of metabolites can result in life threatening symptoms, such as abdominal pain, vomiting, photophobia, neuropathy, bulbar paresis and respiratory failure. Treatment consists primarily of adequate calorie intake e.g. glucose, but is otherwise symptomatic. Anaesthetic drug recommendations are based both on animal experiments and patient experience, primarily case histories. An array of local anaesthetics, hypnotics, sedatives, neuroleptics, analgesics, muscle relaxants, inhalation anaesthetics and some antibiotics are reviewed. Patients with a history of porphyria should be in an optimal condition and maintain a high calorie intake perioperatively. The pre-operative fast should be a minimum and iv-glucose is advisable while fasting. There are anaesthetic agents that are safe for both regional and general anaesthesia.
