经鼻盲探气管插管装置新技术的临床应用

Application of blind nasotracheal intubation with BTII new tecnique

目的探讨经鼻盲探气管插管装置(BTII)的临床应用效果。方法常规全麻下行手术的困难气道患者30例均分为两组:Ⅰ组应用BTII新技术;Ⅱ组采用传统经鼻盲探气管插管。记录并比较两组插管成功率、2次及2次以上成功例数、所有患者插管次数、插管所需时间T(计算插管时间从第一次试行插管算起)、记录术后随访咽喉疼痛及声音嘶哑例数。结果Ⅰ组的插管成功率明显高于Ⅱ组(93.3%vs.60.0%)(P<0.05)。Ⅰ组插管所需时间明显少于Ⅱ组[(140.8±41.7)svs.(365.6±180.9)s](P<0.05),插管操作次数明显少于Ⅱ组[(2.7±0.9)次vs.(6.5±3.5)次](P<0.05)。术后Ⅰ组咽喉疼痛及声音嘶哑发生率少于Ⅱ组(6.7%vs.26.7%)(P<0.05)。结论与传统经鼻盲探气管插管相比,应用BTII引导插管装置用于困难气管插管具有操作方便、插管成功率高和并发症少的优势。

Objective To observe the application of blind nasotracheal intubation with blind tracheal intubation instrument（BTII）.Methods Thirty patients with difficult airway undergoing general anesthesis were divided into two groups with 15 cases each.Blind nasotracheal intubation with BTII was performed in group A and conventional tecnique was carried out in group B.Success rate of intubation,the unmber and the time spent on intubating,and complication were recorded.ResultsSuccess rate of intubation was higher in group A than that in group B（93.3% vs. 60.0%）（P0.05）.The average number of intubating for each case was less in group A than that in group B ／[（2.7±0.9） times vs. （6.5±3.5） times／]（P0.05）.The time spent on tubating was less in group A than that in group B ／[（140.8±41.7） s vs. （365.6±180.9） s／]（P0.05）.The incidence of postoperative sore throat and horseness was less in group A than that in group B （6.7% vs. 26.7%）（P0.05）.Conclussion Compared to conventional tecnique,blind nasotracheal intubation with BTII has the advantages of higher success rate,less time spent on the intubating and less complication in the patients with difficult airway.
