Ultrasound
Ultrasound-guided detection of endobronchial intubation depth by loss of lung sliding sign in the left lung field
干预措施: Ultrasound-guided determination of cuffless RAE tube depth (Behavioral)
Auscultation
Auscultation-guided detection of endobronchial intubation depth by loss of breathing sound in the left lung field
干预措施: Auscultation-guided determination of cuffless RAE tube depth (Behavioral)
结局指标
主要结局
The proportion of optimal location of the cuffless Oral RAE tube (%)
时间窗: during operation (until endotracheal extubation) up to 18 hour after induction
The distance between the tip of cuffless RAE tube and right pulmonary artery is within the -5mm \~ +5mm value of the distance between the T2 mid-vertebra and carina (optimal depth)
次要结局
- M-distance (between the carina and the T2 mid-vertebra)(during operation up to 18 hour after induction)
- Distance between the optimal depth and the relocated depth(during operation up to 18 hour after induction)
- Subglottic diameter at the cricoid cartilage level(during operation)
- ID and OD of optimal cuffless oral RAE tube(during operation up to 18 hour after induction)
- Time from intubation to confirming the tube depth(during operation up to 18 hour after induction)
- Distance between the optimal depth and the manufacturer's recommended depth(during operation up to 18 hour after induction)
- Airway leakage pressure(during operation up to 18 hour after induction)
- Incidence of the intraoperative airway-related events(during operation up to 18 hour after induction)
- Incidence of the airway-related symptoms after extubation(up to 18 hour after induction)
