Talk:Myotonia

note
RE: proposed merger with myotonia congenita. This would be an inappropriate merger. Myotonia is also seen in paramyotonia congenita and potassium-aggravated myotonia (among others). We should keep this article as a general myotonia description so it doesn't have to be described repetitively elsewhere -Dpryan 22:04, 27 July 2006 (UTC)

People suffering from disorders involving myotonia can have a life threatening reaction to certain anaesthetics, one of these conditions occurs when the patient is under anaesthetic and is termed " Malignant Hyperthermia ". Anaesthesiologists cannot diagnose this condition until the patient is under anaesthetic so this condition is very life threatening. Is this always true? Is malignant hyperthermia otherwise found? —Preceding unsigned comment added by 206.207.158.99 (talk) 06:17, 7 April 2008 (UTC)

Malignant hyperthermia is always associated with a channelopathy. There are channelopathies that cause it and do not cause Myotonia, and there are channelopathies that cause myotonia and not cause maligant hyperthermia. Furthermore, malignant hyperthermia is not caused by anesthetics themselves, but by muscle relaxers commonly used when anesthetic is applied (especially gaseous ones. The caffeine halothane contracture test allows safely testing for malignant hyperthermia without the risk of a systemic reaction. — Preceding unsigned comment added by Haxxorz596 (talk • contribs) 02:22, 17 November 2019 (UTC)
