Figure 2
Up-and-down sequential allocation analysis of intranasal DEX was performed in all pediatric patients receiving sedation for TTE in both groups. The dose increment/decrement was 0.2 μg/kg. The calculated ED50 was 2.486 μg/kg (2.530 μg/kg) in group A and 2.485 μg/kg (2.500 μg/kg) in group B.
