The Airtraq® optical laryngoscope (Prodol Ltd., Vizcaya, Spain) is a novel disposable device facilitating tracheal intubation in routine and difficult airway patients. No data investigating routine tracheal intubation using the Airtaq® in patients at a high cardiac risk are available at present. Purpose of this study was to investigate the feasibility and hemodynamic implications of tracheal intubation with the Aitraq® optical laryngoscope, in high-risk cardio-surgical patients.
123 consecutive ASA III patients undergoing elective coronary artery bypass grafting were routinely intubated with the Airtraq® laryngoscope. Induction of anesthesia was standardized according to our institutional protocol. All tracheal intubations were performed by six anesthetists trained in the use of the Airtraq® prior.
Overall success rate was 100% (n = 123). All but five patients trachea could be intubated in the first attempt (95,9%). 5 patients were intubated in a 2nd (n = 4) or 3rd (n = 1) attempt. Mean intubation time was 24.3 s (range 16-128 s). Heart rate, arterial blood pressure and SpO2 were not significantly altered. Minor complications were observed in 6 patients (4,8%), i.e. two lesions of the lips and four minor superficial mucosal bleedings. Intubation duration (p = 0.62) and number of attempts (p = 0.26) were independent from BMI and Mallampati score.
Tracheal intubation with the Airtraq® optical laryngoscope was feasible, save and easy to perform in high-risk patients undergoing cardiac surgery. In all patients, a sufficient view on the vocal cords could be obtained, independent from BMI and preoperative Mallampati score.

Airtraq®可视喉镜（Prodol有限公司，西班牙比斯开省）是一种新型一次性器械，可辅助常规气道和困难气道患者进行气管插管。目前尚无关于在心脏高危患者中使用Airtraq®进行常规气管插管的数据。本研究旨在探讨在高危心脏手术患者中使用Aitraq®可视喉镜进行气管插管的可行性及对血流动力学的影响。
123例连续接受择期冠状动脉搭桥术的ASA III级患者，使用Airtraq®喉镜进行常规插管。麻醉诱导按照我们机构的方案进行标准化。所有气管插管均由6名之前接受过Airtraq®使用培训的麻醉医生完成。
总体成功率为100%（n = 123）。除5例患者外，其余所有患者均在首次尝试时成功插管（95.9%）。5例患者在第二次（n = 4）或第三次（n = 1）尝试时成功插管。平均插管时间为24.3秒（范围16 - 128秒）。心率、动脉血压和SpO2无显著变化。6例患者（4.8%）出现轻微并发症，即2例唇部损伤和4例轻微浅表黏膜出血。插管持续时间（p = 0.62）和尝试次数（p = 0.26）与BMI和马兰帕蒂评分无关。
在接受心脏手术的高危患者中，使用Airtraq®可视喉镜进行气管插管是可行、安全且易于操作的。在所有患者中，均可获得足够的声门视野，与BMI和术前马兰帕蒂评分无关。
