We aimed to determine if using the EndoFlex tracheal tube on the first intubation attempt provided improved placement times and intubation success compared with a standard-type tracheal tube in 50 patients undergoing gynaecological surgery in a prospective, randomised, cross-over trial. We found that using the EndoFlex resulted in shorter intubation times (mean (SD) 14.8 (9.7) vs 30.1 (30.5) s), easier intubation (VAS, median (range) 10 (0-70) vs 20 (0-100)), and an increased rate of successful insertion at the first attempt; all p < 0.001. Flexing the distal tip of the EndoFlex was used in 18 patients. There were reductions in the use of external laryngeal pressure, advancement of laryngoscope blade and increased lifting force when intubating with the EndoFlex. Furthermore, patients with a grade 2 (19/50) or 3 (6/50) laryngoscopic view had shorter intubation times, easier intubation and reduced insertion attempts with the EndoFlex. The EndoFlex is a satisfactory alternative to a standard-type tracheal tube, even with an anterior larynx.
在一项前瞻性、随机、交叉试验中，我们旨在确定对于50例接受妇科手术的患者，与标准型气管导管相比，首次插管尝试时使用EndoFlex气管导管是否能缩短置管时间并提高插管成功率。我们发现，使用EndoFlex可缩短插管时间（均值（标准差）14.8（9.7）秒对30.1（30.5）秒），使插管更容易（视觉模拟评分，中位数（范围）10（0 - 70）对20（0 - 100）），且首次尝试成功插入的比率增加；所有p < 0.001。18例患者使用了EndoFlex远端尖端的弯曲功能。使用EndoFlex插管时，外部喉压迫的使用减少、喉镜叶片推进减少且提升力增加。此外，喉镜视野为2级（19/50）或3级（6/50）的患者使用EndoFlex时插管时间更短、插管更容易且插入尝试次数减少。即使对于喉部靠前的患者，EndoFlex也是标准型气管导管的一种令人满意的替代选择。
