Clinical Trial Summary

Purpose: To compare the efficacy and safety of TCI tube core and ordinary tube core assisted tracheal intubation in simulating difficult airway under visual laryngoscope, and to provide reference for clinical application

Description:

Endotracheal intubation plays an important role in contemporary clinical anesthesia. Direct laryngoscope intubation is the traditional intubation method in anesthesia and emergency medical work. However, due to the constraints of the operator's technical level, the abnormal airway structure and the condition of patients, about 1.5% ~ 8.5% of the cases of intubation difficulties occur. It's even impossible to intubate. Failure of intubation can lead to major complications, including brain damage and death. When a tracheal intubation cannot be placed on the first two attempts, the intubation is classified as difficult, and repeated routine tracheal intubation may lead to morbidity in the patient, and the incidence of airway related complications increases significantly with the number of tracheal intubations. Difficult intubation accounted for 4% of operating room intubation and 10% of intubation outside the operating room. For patients with high glottis and short epiglottis, although the glottis can be seen, intubation is difficult to place. The effectiveness and safety of TCI tube assisted intubation under visual laryngoscope and ordinary tube tube assisted intubation in simulated difficult airway were compared to provide reference for clinical application.
