The risk factors for difficult airway or failed airway: a prospective cohort study Airway management is always the first priority and time-treasures in critical ill-patients. Improper managementof difficult airway or resultant fail airway would bring poor prognosis to patients. We investigated the risk factors of difficult or fail airway from the multiple dimension of factors including patients, healthcare and airway devices. We enrolled 252 intubated patients, including 37 trauma patients, 55 patients (22%) with difficult airway, and 22 patients (8.7%) with fail airway. In analysis of risk factors of difficult airway, factors including obesity, short neck or thickness of soft tissue, facial deformities and oral-nasal bleeding have positive association with fail airway, but the seniority of healthcare providers had no effect. However, experienced healthcare providers have more success rate after the occurrence of fail airway. The most complications of fail airway include airway trauma and hypoxia. As compared with non-trauma patients, trauma patients have more episodes of fail airway, difficult airway, and use of RSI, rescue airway for fail airway, airway trauma and vomiting. Therefore, it is necessary to establish an easy and safe standard guideline in daily practice of difficult and urgent airway management for healthcare providers.

Airway management in patients with suspected cervical spine injury plays an important role in the pathway of care of trauma patients. The aim of this study was to evaluate three different airway devices during intubation of a patient with reduced cervical spine mobility. Forty students of the third year of emergency medicine studies participated in the study (F=26,M=14). The time required to obtain a view of the entry to the larynx and successful ventilation time were recorded. Cormack-Lehane laryngoscopic view and damage to the incisors were also assessed. All three airway devices were used by each student (a novice) and they were randomly chosen. The mean time required to obtain the entry-to-the-larynx view was the shortest for the Macintosh laryngoscope 13.4 s (±2.14). Truview Evo2 had the shortest successful ventilation time 35.7 s (±9.27). The best view of the entry to the larynx was obtained by the Totaltrack VLM device. The Truview Evo2 and Totaltrack VLM may be an alternative to the classic Macintosh laryngoscope for intubation of trauma patients with suspected injury to the cervical spine. The use of new devices enables achieving better laryngoscopic view as well as minimising incisor damage during intubation.

In critically ill patients in Intensive Care Unit (ICU), patency of airway and managementof difficult airway are of utmost importance. The incidence of difficult intubation maybe 10% to 22% depending on the various factors in patient as well as availability ofequipment facilities. As compared to the regular surgery in operation theatre, themanagement of airway in critically ill patients is considerably different and morechallenging. The physiological reserve and co-morbidities are more common in criticallyill patients. In ICU, recent techniques of airway management must be considered andpracticed, such as videolaryngoscope (VLS), fiberoptic bronchoscope and supraglotticdevices. The success for airway management would be greater if airway expert, therequired devices and an adequate protocol are available. The outcome of managingairway would be enhanced if best use of available airway devices in a particular hospitalsetup since every instrument may not be available. The standard guidelines for difficultairway and the protocol of individual hospital may reduce the complications; hencemust be followed. The availability of difficult airway cart and capnograph is a must. Theindications and timing of surgical airway must be clear to the airway team. The Trainingcourses for the staff in ICU should be held regularly to apprise them of advancementin airway management. The best use of available airway equipment should be made incritically ill patients. At least, one airway expert must be accessible in ICU at any giventime.

Patients undergoing thyroid surgery with retrosternal goitre may raise concerns for the anaesthetist, especially airway management. We reviewed a multicentre prospective thyroid surgery database and extracted data for those patients with retrosternal goitre. Additionally, we reviewed the anaesthetic charts of patients with retrosternal goitre at our institution to identify the anaesthetic induction technique and airway management. Of 4572 patients in the database, 919 (20%) had a retrosternal goitre. Two cases of early postoperative tracheomalacia were reported, one in the retrosternal group. Despite some very large goitres, no patient required tracheostomy or cardiopulmonary bypass and there were no perioperative deaths. In the subset of 133 patients managed at our institution over six years, there were no major adverse anaesthetic outcomes and no patient had a failed airway or tracheomalacia. In the latter cohort, of 32 (24%) patients identified as having a potentially difficult airway, 17 underwent awake fibreoptic tracheal intubation, but two of these were abandoned and converted to intravenous induction and general anaesthesia. Eleven had inhalational induction; two of these were also abandoned and converted to intravenous induction and general anaesthesia. Of those suspected as having a difficult airway, 28 (87.5%) subsequently had direct laryngoscopy where the laryngeal inlet was clearly visible. We found no good evidence that thyroid surgery patients with retrosternal goitre, with or without symptoms and signs of tracheal compression, present the experienced anaesthetist with an airway that cannot be managed using conventional techniques. This does not preclude the need for multidisciplinary discussion and planning.

Death and severe morbidity attributable to anesthesia are commonly associated with failed difficult airway management. When an airway emergency develops, immediate access to difficult airway equipment is critical for implementation of rescue strategies. Previously, national expert consensus guidelines have provided only limited guidance for the design and setup of a difficult airway trolley. The overarching aim of the current work was to create a dedicated difficult airway trolley (for patients>12 years old) for use in anesthesia theatres, intensive care units, and emergency departments. A systematic literature search was performed, using the PubMed, Embase, and Google Scholar search engines. Based on evidence presented in 11 national or international guidelines, and peer-reviewed journals, we present and outline a difficult airway trolley organized to accommodate sequential progression through a four-step difficult airway algorithm. The contents of the top four drawers correspond to specific steps in the airway algorithm (A = intubation, B = oxygenation via a supraglottic airway device, C = facemask ventilation, and D = emergency invasive airway access). Additionally, specialized airway equipment may be included in the fifth drawer of the proposed difficult airway trolley, thus enabling widespread use. A logically designed, guideline-based difficult airway trolley is a vital resource for any clinician involved in airway management and may aid the adherence to difficult airway algorithms during evolving airway emergencies. Future research examining the availability of rescue airway devices in various clinical settings, and simulation studies comparing different types of difficult airway trolleys, are encouraged.

The supraglottic airway’s usefulness as a dedicated airway is the subject of continuing development. We report the case of an obese patient with unpredicted difficult airway management in which a new “continuous ventilation technique” was used with the Aura-i laryngeal mask and the aScope-2 devices. The aScope-2/Aura-i system implemented airway devices for the management of predictable/unpredictable difficult airway. The original technique required the disconnection of the mount catheter from Aura-i, the introduction of the aScope-2 into the laryngeal mask used as a conduit for video assisted intubation and then towards the trachea, followed by a railroading of the tracheal tube over the aScope-2. This variation in the technique guarantees mechanical ventilation during the entire procedure and could prevent the risk of hypoventilation and/or hypoxia.

Determinar los factores predictivos de una vía aérea difícil constituye un reto para el médico anestesiólogo. La mayoría de guías actuales, sitúan los videolaringoscopios como elementos de rescate de una vía aérea fallida, tras una laringoscopia tradicional óptima. Establecer un algoritmo que en base a unas características físicas, permita determinar qué pacientes se beneficiarán del uso del videolaringoscopio como primera opción, puede suponer una ventaja y una disminución en los problemas relacionados con la vía aérea. Por otra parte, establecer cuáles de estos factores predicen con más fuerza una dificultad con el videolaringoscopio, nos ayudará a realizar mejores planes de abordaje y una óptima toma de decisiones sobre una vía aérea difícil. Este algoritmo ha sido capaz de conseguir la intubación traqueal de todos los pacientes en los que se ha previsto una laringoscopia difícil. ABSTRACT Moving towards videolaryngoscopy handling as first option in difficult airway management? Determining the predictors of a difficult airway is a challenge for the anesthesiologist. Most current guides place videolaryngoscopes as recue elements of a failed airway, after an optimal traditional laryngoscopy. Establishing an algorithm which, based on physical charcteristics, allows to determine which patients will benefit from the use of videolaryngoscopy as a first option, may lead to a potential advantage and a net decrease in airway related problems. On the other hand, establishing which of those factors predict in a more reliable way a difficulty with the videolaryngoscopy, will contribute to make better plans of approach as well as an optimal decision making on a difficult airway. This algorithm has been able to achieve tracheal intubation of all patients for which a difficult laryngoscopy is expected.

Background The single-use supraglottic airway devices LMA-Supreme (LMA-S; Laryngeal Mask Company, Henley-on-Thames, United Kingdom) and i-gel (Intersurgical Ltd, Wokingham, Berkshire, United Kingdom) have a second tube for gastric tube insertion. Only the LMA-S has an inflatable cuff. They have the same clinical indications and might be useful for difficult airway management. This prospective, crossover, randomized controlled trial was performed in a simulated difficult airway scenario using an extrication collar limiting mouth opening and neck movement. Methods Sixty patients were included. Both devices were placed in random order in each patient. Primary outcome was overall success rate. Other measurements were time to successful ventilation, airway leak pressure, fiberoptic glottic view, and adverse events. Results Success rate for the LMA-S was 95% versus 93% for the i-gel (P = 1.000). LMA-S needed shorter insertion time (34 +/- 12 s vs. 42 +/- 23 s, P = 0.024). Tidal volumes and airway leak pressure were similar (LMA-S 26 +/- 8 cm H20; i-gel 27 +/- 9 cm H20; P = 0.441). Fiberoptic view through the i-gel showed less epiglottic downfolding. Overall agreement in insertion outcome was 54 (successes) and 1 (failure) or 55 (92%) of 60 patients. The difference in success rate was 1.7% (95% CI -11.3% to 7.6%). Conclusions Both airway devices had similar insertion success and clinical performance in the simulated difficult airway situation. The authors found less epiglottic downfolding and better fiberoptic view but longer insertion time with the i-gel. Our study shows that both devices are feasible for emergency airway management in patients with reduced neck movement and limited mouth opening.

We report a case of prehospital “cannot intubate” and “cannot ventilate” scenarios successfully managed by strictly following a difficult airway management algorithm. Five airway devices were used: the Macintosh laryngoscope, the gum elastic Eschmann bougie, the LMA Fastrach, the Melker cricothyrotomy cannula, and the flexible fiberscope. Although several airway devices were used, overall airway management duration was relatively short, at 20 min, because for each scenario, failed primary and secondary backup devices were quickly abandoned after 2 failed attempts, each attempt of no more than 2 min in duration, in favor of the tertiary rescue device. Equally, all three of these rescue devices failed, an uncuffed cricothyroidotomy cannula was inserted to restore optimal arterial oxygenation until a definitive airway was secured in the ICU using a flexible fiberscope. Our case reinforces the need to strictly follow a difficult airway management algorithm that employs a limited number of effective devices and techniques, and highlights the imperative for early activation of successive preplanned steps of the algorithm.
