简要总结
This is a parallel and randomized-controlled clinical study aimed to identify the optimized size of atomized particles of 2% lidocaine that can provide the best topical anesthesia during ATI. To determine the effect of nebulization with different sizes of atomized particles of 2% lidocaine on cough, reaction, and comfort during ATI in patients with predicted difficult airway.
