Malignant hyperthermia (MH)

چکیده
Malignant hyperthermia (MH) or malignant hyperpyrexia is a rare life-threatening condition that is usually triggered by exposure to certain drugs used for general anesthesia, specifically the volatile anesthetic agents and the neuromuscular blocking agent, succinylcholine. In susceptible individuals, these drugs can induce a drastic and uncontrolled increase in skeletal muscle oxidative metabolism, which overwhelms the body's capacity to supply oxygen, remove carbon dioxide, and regulate body temperature, eventually leading to circulatory collapse and death if not treated quickly.

A Review of the Factors Affecting the Incidence of Malignant Hyperthermia in the Greater Kansas City Area
Malignant Hyperthermia (MH) is a rare genetic disease. However, it is devastating when it occurs in a patient. MH is usually triggered by inhalational anesthetics and/or depolarizing muscle relaxants. Public awareness of MH has increased with the presentation of an episode on the television program, “House”, and the availability of web-based information. For over 20 years, the MH susceptible pi...
متن کاملAdministrative databases: are they useful for clinical analyses?
To the Editor:—We are pleased that Rosero et al. pursued a study of the epidemiology of malignant hyperthermia (MH). We agree with Rosero et al. that reporting to the North American Malignant Hyperthermia Registry may underestimate MH mortality. From the Malignant Hyperthermia Association of the United States Hotline and the American Society of Anesthesiologists Closed Claims Project database w...
متن کاملRecognizing and managing a malignant hyperthermia crisis: guidelines from the European Malignant Hyperthermia Group.
Survival from a malignant hyperthermia (MH) crisis is highly dependent on early recognition and prompt action. MH crises are very rare and an increasing use of total i.v. anaesthesia is likely to make it even rarer, leading to the potential risk of reduced awareness of MH. In addition, dantrolene, the cornerstone of successful MH treatment, is unavailable in large areas around the world thereby...
متن کاملDeveloping effective drills in preparation for a malignant hyperthermia crisis.
A malignant hyperthermia (MH) crisis is a medical emergency. To give the patient the best possible chance for a successful outcome, a swift, coordinated, multidisciplinary team response is necessary. Malignant hyperthermia occurs infrequently and, as such, details about its diagnosis, treatment, and management must be reviewed and reinforced during periodic education sessions. An MH response pl...
متن کاملCost-effectiveness analysis of stocking dantrolene in ambulatory surgery centers for the treatment of malignant hyperthermia.
BACKGROUND Malignant hyperthermia (MH) is a rare hypermetabolic syndrome of the skeletal muscle and a potentially fatal complication of general anesthesia. Dantrolene is currently the only specific treatment for MH. The Malignant Hyperthermia Association of the United States has issued guidelines recommending that 36 vials (20 mg per vial) of dantrolene remain in stock at every surgery center. ...
متن کاملAnalysis of the clinical variables associated with recrudescence after malignant hyperthermia reactions.
BACKGROUND Some patients develop recrudescence after a malignant hyperthermia (MH) reaction, but it is not clear which patients are at risk. The authors analyzed clinical variables associated with recrudescence after a clinical MH episode. METHODS Data were obtained from Adverse Metabolic Reaction to Anesthesia reports in the North American Malignant Hyperthermia Registry. Patients who underw...
