Résumé
Objective To discuss the practicability and safety of 3.5 mm superfine bronchoscope in children's difficult airway.Methods Twenty-eight children with difficult airway,aged 4 months to 8 years were selected.Intravenous anesthesia was used and autonomous respiration was maintained.The 3.5 mm superfine bronchoscope was used to guide tracheal intubation by nose(mouth).Results Among 28 cases, 1 case had oral bleeding and succeeded after suction and pressurized oxygen supply, and the rest was successful in the first time.The intubation time was(1.50 ± 0.25)min.There was no damage to the whole airway.Success rate was 100%.Conclusions The 3.5 mm superfine bronchoscope in guiding tracheal intubation of children's difficult airway has obvious advantages and security, and it deserves clinical attention and promotion.
