> **NCT04246411** · NA · WITHDRAWN · sponsor: **Seoul National University Hospital**

## Conditions studied

- Intubation Complication
- Child
- Ultrasonography

## Interventions

- **BEHAVIORAL:** Ultrasound-guided determination of cuffless RAE tube depth
- **BEHAVIORAL:** Auscultation-guided determination of cuffless RAE tube depth

## Key facts

- **NCT ID:** NCT04246411
- **Lead sponsor:** Seoul National University Hospital
- **Sponsor class:** OTHER
- **Phase:** NA
- **Study type:** INTERVENTIONAL
- **Status:** WITHDRAWN
- **Start date:** 2020-02-01
- **Primary completion:** 2021-12-31
- **Final completion:** 2021-12-31
- **Target enrollment:** 0 (ACTUAL)
- **Why stopped:** It was confirmed that cuffed RAE tubes with small diameter could be used, so there was no reason to use RAE cuffless tubes.
