The next most appropriate management for this 21-year-old woman with MDMA (ecstasy) toxicity is immediate supportive care with aggressive cooling measures, intravenous fluid resuscitation with normal saline, benzodiazepines for seizure control, and close monitoring in an intensive care setting. Specifically, administer lorazepam 2-4 mg IV or diazepam 5-10 mg IV for seizure control, as supported by the study 1 which found lorazepam to be more effective than phenytoin for initial intravenous treatment of overt generalized convulsive status epilepticus. Initiate cooling with ice packs to axilla and groin, and begin IV normal saline at 150-200 mL/hour while monitoring electrolytes. Respiratory support with supplemental oxygen or mechanical ventilation may be necessary given her respiratory depression. Electrolyte abnormalities should be corrected gradually, particularly addressing hyponatremia with careful fluid management rather than rapid sodium correction to avoid central pontine myelinolysis, as cautioned in the study 2. Potassium replacement should be initiated for hypokalemia, typically with IV potassium chloride 10-20 mEq over 1 hour for severe deficiency. Continuous cardiac monitoring is essential due to the risk of arrhythmias. This approach addresses the life-threatening complications of MDMA toxicity, which causes serotonin syndrome, inappropriate ADH secretion leading to hyponatremia, hyperthermia from increased muscle activity and impaired thermoregulation, and metabolic derangements that can lead to rhabdomyolysis and multi-organ failure if not promptly treated. The most recent study 3 on intravenous lorazepam dosing strategies for status epilepticus supports the use of a dose of 0.1 mg/kg/dose, up to a maximum of 4 mg, which aligns with the recommended dose for seizure control in this patient. Given the potential for underdosing lorazepam, as highlighted in 3, it is crucial to ensure adequate dosing to prevent refractory status epilepticus. Overall, the management strategy should prioritize addressing the immediate life-threatening complications while carefully managing electrolyte imbalances and monitoring for potential complications.
