a 17 year old male who underwent surgery for thoracic outlet syndrome developed a postoperative complication which was labelled and diagnosed as malignant hyperthermia in kerman medical center. the temperature recorded was 43°c, pac02 70 mmhg and serum potassium level was 7 meq/l. the patient was hospitalized in the intensive care unit for 10 days. on discharge, the patient had aphasia and inco...

''Malignant Hypothermia'' syndrome is a rare, but dangerous occurrence, the aetiology of which is not known. Up to this date 180 cases have been reported. This syndrome i's seen generally in :male children over age of two years, and especially in adolescent males. Also those people with muscular abnormalities are more susciptable to this illnes'S. Anaesthetic agent such as halothane or muscular...

OBJECTIVES Malignant hyperthermia susceptibility is an important risk factor during general anesthesia. Affected patients have an asymptomatic but potentially lethal hypermetabolic reaction after contact with volatile anesthetics or succinylcholine. Classic symptoms include hemodynamic instability, combined with acidosis, rigor, and hyperthermia. During cardiopulmonary bypass, these signs may b...

case presentation we report a male patient with leigh’s syndrome and a family history suggestive of unknown hypotonia and malignant hyperthermia presenting for dental rehabilitation. conclusions dexmedetomidine with remifentanil can be used with no complication in this senerio. introduction usually presenting in infancy, leigh’s syndrome is an inherited condition often manifesting with seizures...

Malignant hyperthermia is a potentially lethal inherited disorder characterized by disturbance of calcium homeostasis in skeletal muscle. Volatile anesthetics and/or the depolarizing muscle relaxant succinylcholine may induce this hypermetabolic muscular syndrome due to uncontrolled sarcoplasmic calcium release via functionally altered calcium release receptors, resulting in hypoxemia, hypercap...

We report a case of malignant hyperthermialike syndrome in a living-donor liver transplant recipient with no familial history of malignant hyperthermia or exposure to known triggering drugs. The patient showed many features of a typical malignant hyperthermia episode, and The Clinical Grading Scale defined this case as almost certain to be an episode of malignant hyperthermia (rank 5). However,...

Malignant hyperthermia is a hypermetabolic response to inhalation agents (such as halothane, sevoflurane, and desflurane), succinylcholine, vigorous exercise, and heat. Reactions develop more frequently in males than females (2 : 1). The classical signs of malignant hyperthermia are hyperthermia, tachycardia, tachypnea, increased carbon dioxide production, increased oxygen consumption, acidosis...

BACKGROUND Central core disease and malignant hyperthermia are human disorders of skeletal muscle resulting from aberrant Ca2+ handling. Most malignant hyperthermia and central core disease cases are associated with amino acid changes in the type 1 ryanodine receptor (RyR1), the skeletal muscle Ca2+-release channel. Malignant hyperthermia exhibits a gain-of-function phenotype, and central core ...
