What is the dose of magnesium sulfate administered for the treatment of torsades de pointes during CPR?

The recommended dose of magnesium sulfate for the treatment of torsades de pointes during CPR is 25-50 mg/kg IV. This dosage is effective in stabilizing the cardiac membrane and is important for managing this specific type of polymorphic ventricular tachycardia that can occur in pediatric patients, particularly in those with conditions that might cause prolonged QT intervals. Administering magnesium sulfate in this range allows for rapid correction of magnesium deficiency and helps to restore normal cardiac rhythm, which is crucial during the emergency management of arrhythmias.

The selection of this dosage reflects the guidelines and evidence-based practice that emphasize effective intervention while minimizing risks of toxicity, clarifying the appropriate approach to addressing torsades de pointes in a critical setting. Providing care within these established dosing guidelines supports the safety and efficacy of the treatment intervention for pediatric patients.
