The WEI Jet Endotracheal Tube (WEI JET) is a new tracheal tube that facilitates both oxygenation and ventilation during the process of intubation and assists tracheal intubation in patients with difficult airway. We evaluated the effectiveness and usefulness of the WEI JET in combination with lightwand under direct laryngoscopy in difficult tracheal intubation due to unstable cervical spine.
Ninety patients with unstable cervical spine disorders (ASA I-III) with general anaesthesia were included and randomly assigned to three groups, based on the device used for intubation: lightwand only, lightwand under direct laryngoscopy, lightwand with WEI JET under direct laryngoscopy.
No statistically significant differences were detected among three groups with respect to demographic characteristics and C/L grade. There were statistically significant differences between three groups for overall intubation success rate (p = 0.015) and first attempt success rate (p = 0.000). The intubation time was significantly longer in the WEI group (110.8±18.3 s) than in the LW group (63.3±27.5 s, p = 0.000) and DL group (66.7±29.4 s, p = 0.000), but the lowest SpO2 in WEI group was significantly higher than other two groups (p<0.01). The WEI JET significantly reduced successful tracheal intubation attempts compared to the LW group (p = 0.043). The severity of sore throat was similar in three groups (p = 0.185).
The combined use of WEI JET under direct laryngoscopy helps to assist tracheal intubation and improves oxygenation during intubation in patients with difficult airway secondary to unstable spine disorders.

WEI喷射气管导管（WEI JET）是一种新型气管导管，在插管过程中便于给氧和通气，并协助困难气道患者进行气管插管。我们评估了在直接喉镜检查下，WEI JET联合光棒用于颈椎不稳定导致的困难气管插管的有效性和实用性。
纳入90例接受全身麻醉的颈椎不稳定疾病患者（ASA I-III级），根据插管所用设备随机分为三组：仅用光棒组、直接喉镜检查下用光棒组、直接喉镜检查下用光棒联合WEI JET组。
三组在人口统计学特征和C/L分级方面未检测到统计学显著差异。三组在总体插管成功率（p = 0.015）和首次尝试成功率（p = 0.000）方面存在统计学显著差异。WEI组的插管时间（110.8±18.3秒）显著长于光棒组（63.3±27.5秒，p = 0.000）和直接喉镜检查下用光棒组（66.7±29.4秒，p = 0.000），但WEI组的最低SpO2显著高于其他两组（p<0.01）。与光棒组相比，WEI JET显著减少了成功气管插管的尝试次数（p = 0.043）。三组的咽痛严重程度相似（p = 0.185）。
在直接喉镜检查下联合使用WEI JET有助于协助气管插管，并改善因脊柱不稳定疾病导致的困难气道患者插管期间的氧合。
