In most people with malignant hyperthermia susceptibility, they have few or no symptoms unless they are exposed to a triggering agent. The most common triggering agents are volatile anesthetic gases, such as halothane , sevoflurane , desflurane , isoflurane , enflurane or the depolarizing muscle relaxants suxamethonium and decamethonium used ...
Drug-induced fever is a symptom of an adverse drug reaction wherein the administration of drugs intended to help a patient causes a hypermetabolic state resulting in fever. The drug may interfere with heat dissipation peripherally, increase the rate of metabolism , evoke a cellular or humoral immune response , mimic endogenous pyrogen , or ...
Recreational drugs such as amphetamines [17] and cocaine, [18] PCP, dextromethorphan, LSD, and MDMA may cause hyperthermia. [2] Malignant hyperthermia is a rare reaction to common anesthetic agents (such as halothane) or the paralytic agent succinylcholine. Those who have this reaction, which is potentially fatal, have a genetic predisposition. [2]
The efficacy of dantrolene in humans was later confirmed in a large, multicenter study published in 1982, [21] and confirmed epidemiologically in 1993. [22] Before dantrolene, the only available treatment for malignant hyperthermia was procaine, which was associated with a 60% mortality rate in animal models. [20]
Succinylcholine may also trigger malignant hyperthermia in rare cases in patients who may be susceptible. In depolarizing the musculature, suxamethonium may trigger a transient release of large amounts of potassium from muscle fibers. This puts the patient at risk for life-threatening complications, such as hyperkalemia and cardiac arrhythmias.
The diagnosis is suggested on patients with a history of drug exposure to the most common inducing agents such as strong antidopaminergic medications. [6] [40] The differential diagnosis includes serotonin syndrome, [41] encephalitis, toxic encephalopathy, status epilepticus, heat stroke, catatonia and malignant hyperthermia.
New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...
Hyperthermia therapy (or hyperthermia, or thermotherapy) is a type of medical treatment in which body tissue is exposed to temperatures above body temperature, in the region of 40–45 °C (104–113 °F). Hyperthermia is usually applied as an adjuvant to radiotherapy or chemotherapy, to which it works as a sensitizer, in an effort to treat cancer.
