Myotonia congenita (MC) is caused by a defect in the skeletal muscle chloride channel function, which may cause sustained membrane depolarisation. We describe a previously healthy 32-year-old woman who developed a life-threatening muscle spasm and secondary ventilation difficulties following a preoperative injection of suxamethonium. The muscle spasms disappeared spontaneously and the surgery proceeded without further problems. When subsequently questioned, she reported minor symptoms suggesting a myotonic condition. Myotonia was found on clinical examination and EMG. The diagnosis MC was confirmed genetically. Neither the patient nor the anaesthetist were aware of the diagnosis before this potentially lethal complication occurred. We give a brief overview of ion channel disorders including malignant hyperthermia and their anaesthetic considerations.

This article is dedicated to our teacher, Prof. Erich Kuhn, Heidelberg, on the occasion of his 88th birthday on 23rd November 2008. In contrast to muscular dystrophies, the muscle channelopathies, a group of diseases characterised by impaired muscle excitation or excitation-contraction coupling, can fairly well be treated with a whole series of pharmacological drugs. However, for a proper treatment proper diagnostics are essential. This article lists state-of-the-art diagnostics and therapies for the two types of myotonic dystrophies, for recessive and dominant myotonia congenita, for the sodium channel myotonias, for the primary dyskalemic periodic paralyses, for central core disease and for malignant hyperthermia susceptibility in detail. In addition, for each disorder a short summary of aetiology, symptomatology, and pathogenesis is provided.
