目的 探讨3.5mm超细纤维支气管镜在小儿困难气道中的应用及可行性和安全性.方法 28例年龄4个月至8岁具有困难气管插管指征的患儿,采用静脉麻醉、保留自主呼吸的方式,3.5mm超细纤维支气管镜引导经鼻(口)气管插管.结果 28例患儿中除1例口腔出血患儿经吸痰和再次加压给氧后插管成功,其余均一次性插管成功,插管时间(1.50±0.25)min,对气道无损伤,成功率100%.结论 3.5mm超细纤维支气管镜直视引导下插入气管导管,应用于小儿困难气道具有明显优势和安全性,值得临床关注和推广.
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.
