简要总结
Ambu AuraGain, I-gel, Air-Q intubating laryngeal airway are the most commonly used supraglottic airway. In children, they can be used as intubation conduits. However, there has been no guideline for optimal insertion depth of endotracheal tube through those supraglottic airway. In this study, the investigators will measure the distance from grille of those supraglottic airways to glottis using fiberoptic bronchoscope in children undergoing anesthesia. This distance allows us to predict an appropriate depth of endotracheal tube when it should be inserted through each supraglottic airway.

研究组 & 干预措施
Ambu AuraGain
Ambu AuraGain is inserted in children undergoing general anesthesia. The size of AuraGain is as follows: size 1 for children <5 kg, size 1.5 for 5-10kg, size 2 for 10-20kg, size 2.5 for 20-30kg. Fiberoptic bronchoscope will be performed to measure the distance between the grill and vocal cord.
干预措施: fiberoptic bronchoscope (Procedure)
I-gel
I-gel is inserted in children undergoing general anesthesia. The size of I-gel is as follows: size 1 for children weighing 2-5kg, size 1.5 for 5-12kg, size 2 for 10-25kg, size 2.5 for 25-35kg. Fiberoptic bronchoscope will be performed to measure the distance between the grill and vocal cord.
干预措施: fiberoptic bronchoscope (Procedure)
Air-Q intubating laryngeal airway (ILA)
Air-Q ILA is inserted in children undergoing general anesthesia. The size of Air-Q ILA is as follows: size 1 for children between 4-7 kg, size 1.5 for 7-17kg, size 2 for 17-30kg, size 2.5 for 30-50kg. Fiberoptic bronchoscope will be performed to measure the distance between the grill and vocal cord.
