Malignant hyperthermia is an extreme response to certain gases used during anesthesia and/or a muscle depressant used to briefly disable an individual throughout surgical procedure. People with certain inherited muscle mass diseases have MH vulnerability. While malignant hyperthermia itself is not inherited, malignant hyperthermia susceptibility is inherited in an autosomal dominant way. Parents of a person with an evidently new mutation might be evaluated by having contracture screening or molecular genetic testing, if the mutation in the affected person is understood. The risk to other relative of an affected person depend on whether an affected person's parent has the problem. If given these drugs, people in danger of malignant hyperthermia may experience a fast increase in heart rate and body temperature level, extraordinarily fast breathing, muscular tissue strength, break down of muscular tissue fibers, and increased acid levels in the blood and other tissues. Malignant hyperthermia may not occur every time anesthesia is used. Without timely treatment, the difficulties caused by malignant hyperthermia can be deadly. In rare cases, people at risk of malignant hyperthermia have shown signs of a reaction after intense physical activity during extreme heat or humidity, during a viral illness, or when taking statin medicine. If you're at risk of malignant hyperthermia and you do not have a significant response throughout your first exposure to certain anesthesia drugs, you're still at risk if you receive these drugs in the future.
