Malignant (Definition)

The term malignant can be used in several medical contexts, but is primarily used to describe cancers. More dangerous and disorderly than the benign growth of cells, malignant cells have developed genetic changes that can allow it to invade other tissues in an unregulated way. These tumors can later spread, or metastasize, to other parts of the body and ...Read more

What is malignant hyperthermia?

What is malignant hyperthermia?

MH- temp, HR, etc: Mh is an inherited disease that is typically uncovered after the affected person gets anesthesia for surgery. Symptoms include muscle rigidity, fast, irregular heart rate, rapid rise in body temperature to 104f or higher. Mh can lead to muscle breakdown, kidney failure and death. There may be a family history of mh or unexplained death during anesthesia. Mh differs from hyperthermia (heat stroke). ...Read more

Anesthetic reaction: Malignant hyperthermia is a serious, possibly life threatening reaction to certain anesthetic agents including succinylcholine and inhaled anesthetic gases. This condition is often inherited, and involves a mutation of a gene in muscles involved in calcium release. When exposed to triggering agents, the muscles undergo excessive metabolism, leading to muscle breakdown and heat, which cause death. ...Read more

How do you diagnose malignant hyperthermia?

How do you diagnose malignant hyperthermia?

No one simple test: Malignant hyperthermia is a rare life-threatening condtion often triggered by exposure to certain volatile anesthetic gases and succinylcholine (anesthesia uses this during surgery). The metabolism of the skeletal muscle goes into "overdrive", and it is this oxidative process that overwhelms the body's ability to supply oxygen, remove c02. The result is poor regulation of body temperature. ...Read more

Malignant Hyperthermia (Definition)

Malignant hyperthermia is an inherited disease triggered by certain medications used in anesthesia that can lead to a life-threatening crisis during or shortly after surgery. It is fairly rare, but potentially life-threatening if unrecognized and untreated. The malignant hyperthermia association of the United States is an excellent ...Read more
