Tongue Root Retractor For Fibroscopic Intubation

The First Affiliated Hospital with Nanjing Medical University300 enrolled

Overview

Patients admit to the operation rooms of First Affiliated Hospital of Nanjing Medical University and requiring endotracheal intubation for general anesthesia will be enrolled in this case controlled study. Patients 1) aged 18 to 70 years; 2) ASA graded I\~II class; 3) general anesthesia should be performed under endotracheal intubation, will be included from this study. Patients 1) with organ transplant operations; 2) with thoracic and cardiac vascular surgery; 3) with severe heart or lung disease; 4) BMI over 35kg/m2, will be excluded from this study. The primary aim is to compare airway clearance for fibreoptic tracheal intubation in each patient position. Secondary outcomes include times to view the vocal cord and carina, the time for tube advancement through the vocal cords, as well as the total time to achieve tracheal intubation.Two anesthesiologists with 5 years of experience in conventional endotracheal intubation and trained for fibreoptic intubation will perform the maneuvers.

Outcomes

Primary Outcomes

Feasibility of intubation.

Successs of intubation at different attempts.

Time frame: From start of intubation to successfully intubated (the endotracheal tube enters the trachea and the cuff is inflated), usually within 3 minutes.

Secondary Outcomes

Epiglottis level

Airway clearance at the epiglottis level was assessed by observing whether the epiglottis was in contact with the posterior pharyngeal wall

Time frame: within 30 seconds after the beginning of fibroscopy

Carina time

time from the beginning of fibroscopy to the confirmation of the carina

Time frame: within 90 seconds

Successful Intubation on 1st Attemp

the success rate on 1st attempt

Time frame: from start of first intubation to end of first intubation attempt

Number of attempts for tube advancement

number of attempts for tube advancement from the beginning of fibroscopy to the success of the intubation

Time frame: within 120 seconds
