引导钢丝对经鼻气管插管时鼻咽部损伤状况的影响

Nasopharynx trauma on steel guidewire applied for nasotracheal intubation

目的观察在经鼻腔气管插管过程中应用引导钢丝对减轻鼻咽部损伤的作用。方法 120例择期手术患者随机分为观察组(引导钢丝引导经鼻腔插管)和对照组(不用引导钢丝),每组60例。观察两组患者插管所用时间和鼻咽部损伤发生例数。结果观察组从插管至确认导管位置正确所需时间比对照组长[(68.1±13.7)s vs(57.8±11.5)s,P<0.01)];观察组、对照组致鼻咽部损伤者分别为7例(11.7%)和16例(26.7%),差异有统计学意义(χ2=4.357,P<0.05)。结论中心静脉导丝引导经鼻腔气管插管虽然延长插管时间,但可减轻气管插管对鼻咽部的损伤。

Objective To investigate the protection role of steel guidewire applied for nasotracheal intubation on attenuation of nasopharynx trauma. Methods One hundred patients scheduled for selective surgery were randomly divided into observation group in which a steel guidewire applied for nasotracheal intubation and control group in which the guidewire was not applied（60 cases in each group）. Time of nasotracheal intubation and cases of nasopharynx trauma were measured. ResultTime of nasotracheal intubation in observation group was longer than that in control group（68.1±13.7） s vs（57.8±11.5） s,P〈0.01）,and cases of nasopharynx trauma were observed in both groups, but cases of nasopharynx trauma have significant difference in the tow groups, observation group was lower than control group（7 vs 16,χ^2=4.357,P〈0.05）. ConclusionApplication of steel guidewire for nasotracheal intubation may cost more time, but it could ruduce nasopharynx trauma caused by nasotracheal intubation
