目的：比较颌面部骨折术中HC可视喉镜和普通喉镜经鼻气管插管的效果。方法择期行颌面部骨折内固定术患者50例，随机分为两组，分别采用HC可视喉镜组（H组）和普通喉镜组（P组）引导下经鼻腔气管插管，记录直接喉镜下声门显露情况、气管插管时间、喉外压迫例数、Magil插管钳辅助例数、喉镜沾血发生率以及术后咽痛不适发生率。结果 H组声门暴露分级，插管时间明显低于P组(<0.05)，需要Magil插管钳辅助、喉外压迫次数，喉镜沾血发生率均低于P组。结论 HC可视喉镜在颌面部骨折内固定术中引导鼻腔气管插管具有视野暴露好、插管迅速、损伤小、成功率高等优点，值得推广使用。“,”Objective To compare the maxil ofacial fracture video laryngoscope andordinarylaryngoscopy in nasotrachealintubation ef ect. Methods Patients undergoing maxil ofacial fracture internal fixation of 50 cases of patients were randomly divided into video laryngoscope group (H group) and normal laryngoscope group (P group) under the guidance of nasal tracheal intubationby direct laryngoscopy, record the glot is exposure, duration of tracheal intubation, laryngealexternal compression frequency,Magil intubating forceps assisted, blood stained occurredlaryngoscope rate, and Incidence of postoperative sore throat discomfort. Results In H group, glot ic exposure time, intubation was significantly lower than that of P group ( <0.05), need Magilintu-bation forceps assisted, laryngeal external compression times, laryngoscope bloody incidence was lower than that in group P. Conclusion HC video laryngoscope in maxil ofacial fracture internal fixation guide nasal endotracheal intubation with vision good exposure, rapid intubation success rate, lit le damage, etc, is worthy to be popularized.
