The effects were investigated of a 25-minute inhalation of halothane with oxygen on three to four months old pigs of the Large White breed. Symptoms of malignant hyperthermia did not occur. The actual total anesthesia, which causes slight hypoproteinemia, hypoglycemia and hypocholesterolemia without significant changes in the content of non-esterified fatty acids (NEFA) and urea, induced only a slight increase of circulating 11-hydroxycorticosteroids (11-OHCS). The combination of anesthesia with castration of gilts or barrows significantly increased the concentration of 11-OHCS but did not reach the level recorded after the application of ACTH. The higher levels of 11-OHCS were accompanied by higher concentrations of NEFA and glucose. The treatment of the animals lasting half an hour prior to inhalation of halothane at maximum doses or one hour in the control unanesthetized pigs produced an effect, mainly on the 11-OHCS concentration and on the activity of creatine kinase in the plasma. The results indicate that the adrenocortical response to the effect of halothane is not stronger than the response to simple handling connected with excitement and muscular activity of the animals. Therefore there is no reason of considering halothane anesthesia as a factor causing great stress and pigs which in its course do not respond with malignant hyperthermia as animals insensitive to stress. The aptness of denotation of clinical manifestations of genetically defective muscles in pigs is discussed.

A four year child presented with an episode of malignant hyperthermia induced by reexposure to halothane. The episode was associated with early onset of a severe hypoglycemia and liver enzymatic perturbances. Etiology of these perturbances is hard to state precisely in this clinical context, but a hepatic toxicity of halothane and/or by dantrolene is considered.

There are many diseases related to ion channels. Mutations in muscle voltage-gated sodium, potassium, calcium and chloride channels, and acetylcholine-gated channel may lead to such physiological disorders as hyper- and hypokalemic periodic paralysis, myotonias, long QT syndrome, Brugada syndrome, malignant hyperthermia and myasthenia. Neuronal disorders, e.g., epilepsy, episodic ataxia, familial hemiplegic migraine, Lambert-Eaton myasthenic syndrome, Alzheimer's disease, Parkinson's disease, schizophrenia, hyperekplexia may result from dysfunction of voltage-gated sodium, potassium and calcium channels, or acetylcholine- and glycine-gated channels. Some kidney disorders, e.g., Bartter's syndrome, policystic kidney disease and Dent's disease, secretion disorders, e.g., hyperinsulinemic hypoglycemia of infancy and cystic fibrosis, vision disorders, e.g., congenital stationary night blindness and total colour-blindness may also be linked to mutations in ion channels.

McArdle disease or type V glycogenosis is a rare metabolic myopathy consisting of muscle loss and weakness. These patients have risks associated with anaesthesia. They can present with hypoglycaemia, rhabdomyolysis, acute renal failure, and electrolyte changes. It has also been associated with a higher incidence of malignant hyperthermia during the anaesthetic procedure. Intermittent compression due to the measurement of non-invasive pressure, postures on the operating table that may cause muscle contractures, or tremor caused by hypothermia or anaesthesia itself, may trigger rhabdomyolysis in these patients. In this article we present our experience in submitting a patient with McArdle's syndrome to general anaesthesia for total thyroidectomy due to multinodular euthyroid goitre.
