The use of the Airtraq® optical laryngoscope for routine tracheal intubation in high-risk cardio-surgical patients
<p>Abstract</p> <p>Background</p> <p>The Airtraq<sup>® </sup>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<sup>® </sup>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<sup>® </sup>optical laryngoscope, in high-risk cardio-surgical patients.</p> <p>Methods</p> <p>123 consecutive ASA III patients undergoing elective coronary artery bypass grafting were routinely intubated with the Airtraq<sup>® </sup>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<sup>® </sup>prior.</p> <p>Results</p> <p>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 SpO<sub>2 </sub>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.</p> <p>Conclusion</p> <p>Tracheal intubation with the Airtraq<sup>® </sup>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.</p> <p>Trial Registration</p> <p>DRKS 00003230</p
