AbstractSedation during invasive procedures provides appropriate humanitarian care as well as facilitates the completion of procedures. Although generally safe and effective, adverse effects may occur especially in patients with comorbid diseases. One particularly challenging situation is the child with an anterior mediastinal mass who requires sedation during performance of a biopsy to obtain a tissue diagnosis. When there is evidence of airway compromise, it is generally accepted that the maintenance of spontaneous ventilation is necessary as complete airway obstruction may occur, if positive pressure ventilation is chosen. We present the use of a dexmedetomidine-ketamine combination for procedural sedation in a three-year-old child who presented with a large mediastinal mass and respiratory compromise. Previous reports regarding the use of dexmedetomidine and ketamine for procedural sedation are reviewed and the potential efficacy of this combination is discussed.
