A case of malignant hyperthermia that was difficult to be differentiated from oral antipsychotic polypharmacy-associated neuroleptic malignant syndrome

چکیده
Malignant hyperthermia (MH) occurred during anesthesia with volatile inhalation anesthetics in a patient under treatment with multiple oral antipsychotic drugs and with a history of multi-acting receptor-targeted antipsychotic drug (MARTA)-induced elevation of serum creatine kinase (CK). Since the patient was considered to be at high risk for neuroleptic malignant syndrome (NMS) based on this history, differential diagnosis between MH and NMS was difficult at the time of onset. Later, the patient was found to be predisposed to MH based on abnormal high rate of the Ca2+-induced Ca2+ release (CICR). We concluded that MH was induced by the volatile inhalation anesthetics.

Olanzapine-Induced Neuroleptic Malignant Syndrome
Neuroleptic malignant syndrome (NMS) is a rare but life-threatening idiosyncratic side effect resulting from neuroleptic drugs. NMS mainly occurs in patients treated with high-potency typical antipsychotics, but rarely caused by atypical antipsychotics. Although NMS is less common with atypical antipsychotic, but it seems that its incidence is rising due to increased administration of such drug...
متن کاملA rare case of neuroleptic malignant syndrome presenting with serious hyperthermia treated with a non-invasive cooling device: a case report
INTRODUCTION A rare side effect of antipsychotic medication is neuroleptic malignant syndrome, mainly characterized by hyperthermia, altered mental state, haemodynamic dysregulation, elevated serum creatine kinase and rigor. There may be multi-organ dysfunction including renal and hepatic failure as well as serious rhabdomyolysis, acute respiratory distress syndrome and disseminated intravascul...

Neuroleptic malignant syndrome is an uncommon but dangerous complication of antipsychotic drugs, characterized by clinical symptoms that include hyperthermia, severe muscle rigidity, autonomic dysfunction, and altered mental state. Serum creatine kinase (CK) elevation occurs in over 90% of cases. Many diagnostic criteria sets for neuroleptic malignant syndrome have been proposed, all of which i...
متن کاملAmisulpride and neuroleptic malignant syndrome.
Neuroleptic malignant syndrome (NMS) is a rare but lethal complication of neuroleptics. Its incidence ranges between 0.02% and 3%. Amisulpride, a second generation neuroleptic, was associated with rhabdomyolysis in one report and NMS in 2 reports. Although the precise pathogenesis is still unclear, dopamine receptor blockade is theorized to play a central role. Conventional presentations includ...
متن کاملAcute psychosis followed by fever--malignant neuroleptic syndrome or viral encephalitis?
INTRODUCTION Neuroleptic malignant syndrome is rare, but potentially fatal idiosyncratic reaction to antipsychotic medications. It is sometimes difficult to diagnose some clinical cases as neuroleptic malignant syndrome and differentiate it from the acute viral encephalitis. CASE REPORT We reported a patient diagnosed with acute psychotic reaction which appeared for the first time. The treatm...
