A randomised study was carried out in 60 patients to assess the influence of tracheal tube tip design on the ease of railroading a tracheal tube during fibreoptic intubation. A new design of tracheal tube with a tapered tip, without a bevel, was compared with a tracheal tube of standard design. The new design was found to be greatly superior in both oro- and nasotracheal fibreoptic intubation, when compared with the traditional tracheal tube (p < 0.001). The shape of the tip of a tracheal tube is an important determinant of the ease of railroading the tube over an inserted fibrescope.
对60例患者进行了一项随机研究，以评估气管导管尖端设计对纤维支气管镜引导插管时气管导管推进难易程度的影响。将一种新型的、尖端呈锥形且无斜面的气管导管与标准设计的气管导管进行比较。结果发现，与传统气管导管相比，这种新设计在经口和经鼻纤维支气管镜引导插管中均具有显著优势（p < 0.001）。气管导管尖端的形状是决定在插入的纤维支气管镜上推进导管难易程度的一个重要因素。
