Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to find effective dose of remimazolam for inducing loss of consciousness in children aged 2 to 8 years old. We will explore ED90 of remimazolam for loss of consciousness in 2 minutes after intravenous injection, via a up-and-down method with biased-coin design.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

We will administer remimazolam intravenously to the study participants. Remimazolam will be infused in 30 seconds to the participants, and we will wait for 2 minutes for the participants be sedated.

When a participant was not sedated in 2 minutes, dose of remimazolam in the next participant will be escalated by 0.05mg/kg. When a participant was sedated in 2 minutes, dose of remimazolam in the next participant will be decreased by 0.05mg/kg or maintained as same. The probability of decrement and maintenance will be 90% and 10% respectively. The dose of remimazolam in the first participant of the study will be 0.05mg/kg.

We will collect the results and obtain ED90 of remimazolam for loss of consciousness in children aged 2 to 8 years old.
