First described in 1956 subsequent to a reaction reported to the newly introduced antipsychotic drug chlorpromazine, neuroleptic malignant syndrome (NMS) is a rare, potentially life-threatening reaction to antipsychotic drugs characterized by high fever, muscle rigidity, altered mental status, and autonomic instability. All neuroleptics, including newer antipsychotics, have been linked to this condition. Due to similar symptoms, it is debatable if individuals with NMS can be susceptible to malignant hyperthermia (MH). This case report presents the anesthetic care of a 30-year-old male undergoing general anesthesia in the office-based dental environment. The rationale behind the selected total intravenous anesthesia technique without NMS or MH triggering agents is outlined as well as other agents that may still be questionable regarding their trigger effect for NMS.
