Abstract
Background and Objectives: The ARNE score was developed for the prediction of a difficult airway for both general and ear, nose and throat (ENT) surgery with a universal cut-off value. We tested the accuracy of this score in the case of laryngeal surgery and provided an insight into its effects in combination with flexible laryngoscopy. Materials and Methods: This prospective pilot clinical study included 100 patients who were being scheduled for microscopic laryngeal surgery. We calculated the ARNE score for every patient, and flexible laryngoscopy was provided preoperative. Difficult intubation was assessed according to the intubation difficulty score (IDS). Results: A total of 33% patients had difficult intubation according to the IDS. The ARNE score showed limited accuracy for the prediction of difficult intubation in laryngology with p < 0.0001 and an AUC of 0.784. Flexible laryngoscopy also showed limitations when used as an independent parameter with p < 0.0001 and an AUC of 0.766. We defined a new cut-off value of 15.50 for laryngology, according to the AUC. After the patients were divided into two groups, according to the new cut-off value and provided cut-off value, the AUC improved to 0.707 from 0.619, respectively. Flexible laryngoscopy improved the prediction model of the ARNE score to an AUC of 0.882 and of the new cut-off value to an AUC of 0.833. Conclusions: It is recommended to use flexible laryngoscopy together with the ARNE score in difficult airway prediction in patients with laryngeal pathology. Also, the universally recommended cut-off value of 11 cannot be effectively used in laryngology, and a new cut-off value of 15.50 is recommended.

Abstract
INTRODUCTION Emergency airway management is a common and critical task EMS clinicians perform in the prehospital setting. A new set of evidence-based guidelines (EBG) was developed to assist in prehospital airway management decision-making. We aim to describe the methods used to develop these EBGs. METHODS The EBG development process leveraged the four key questions from a prior systematic review conducted by the Agency for Healthcare Research and Quality (AHRQ) to develop 22 different population, intervention, comparison, and outcome (PICO) questions. Evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework and tabulated into the summary of findings tables. The technical expert panel then used a rigorous systematic method to generate evidence to decision tables, including leveraging the PanelVoice function of GRADEpro. This process involved a review of the summary of findings tables, asynchronous member judging, and online facilitated panel discussions to generate final consensus-based recommendations. RESULTS The panel completed the described work product from September 2022 to April 2023. A total of 17 summary of findings tables and 16 evidence to decision tables were generated through this process. For these recommendations, the overall certainty in evidence was "very low" or "low," data for decisions on cost-effectiveness and equity were lacking, and feasibility was rated well across all categories. Based on the evidence, 16 "conditional recommendations" were made, with six PICO questions lacking sufficient evidence to generate recommendations. CONCLUSION The EBGs for prehospital airway management were developed by leveraging validated techniques, including the GRADE methodology and a rigorous systematic approach to consensus building to identify treatment recommendations. This process allowed the mitigation of many virtual and electronic communication confounders while managing several PICO questions to be evaluated consistently. Recognizing the increased need for rigorous evidence evaluation and recommendation development, this approach allows for transparency in the development processes and may inform future guideline development.

Abstract
Airway management is a cornerstone of emergency medical care. This project aimed to create evidence-based guidelines based on the systematic review recently conducted by the Agency for Healthcare Research and Quality (AHRQ). A technical expert panel was assembled to review the evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. The panel made specific recommendations on the different PICO (population, intervention, comparison, outcome) questions reviewed in the AHRQ review and created good practice statements that summarize and operationalize these recommendations. The recommendations address the use of ventilation with bag-valve mask ventilation alone vs. supraglottic airways vs. endotracheal intubation for adults and children with cardiac arrest, medical emergencies, and trauma. Additional recommendations address the use of video laryngoscopy and drug-assisted airway management. These recommendations, and the associated good practice statements, offer EMS agencies and clinicians an opportunity to review the available evidence and incorporate it into their airway management strategies.

Abstract
BACKGROUND In 2017, we established an airway call (AC) team composed of anesthesiologists to improve emergency airway management outside the operating room. In this retrospective analysis of prospectively collected data from the airway registry, we describe the characteristics of patients attended to and practices by the AC team during the first 4 years of implementation. METHODS All AC team activations in which an airway intervention was performed by the AC team between June 2017 and May 2021 were analyzed. RESULTS In all, 359 events were analyzed. Activation was more common outside of working hours (62.1%) and from the intensive care unit (85.0%); 36.2% of AC activations were due to known or anticipated difficult airway, most commonly because of acquired airway anomalies (n = 49), followed by airway edema or bleeding (n = 32) and very young age (≤ 1 years; n = 30). In 71.3% of the cases, successful intubation was performed by the AC team at the first attempt. However, three or more attempts were performed in 33 cases. The most common device used for successful intubation was the videolaryngoscope (59.7%). Tracheal intubation by the AC team failed in nine patients, who then required surgical airway insertion by otolaryngologists. However, there were no airway-related deaths. CONCLUSIONS When coupled with appropriate assistance from an otolaryngologist AC system, an AC team composed of anesthesiologists could be an efficient way to provide safe airway management outside the operating room.

Abstract
BACKGROUND Airway rapid response (ARR) teams can be compiled of anesthesiologists, intensivists, otolaryngologists, general and thoracic surgeons, respiratory therapists, and nurses. The optimal composition of an ARR team is unknown but considered to be resource intensive. We sought to determine the type of technical procedures performed during an ARR activation to inform team composition. METHODS A large urban quaternary academic medical center retrospective review (2016-2019) of adult ARR patients was performed. Analysis included ARR demographics, patient characteristics, characteristics of preexisting tracheostomies, incidence of concomitant conditions, and procedures completed during an ARR event. RESULTS A total of 345 ARR patients with a median age of 60 years (interquartile range, 47-69 years) and a median time to ARR conclusion of 28 minutes (interquartile range, 14-47 minutes) were included. About 41.7% of the ARR had a preexisting tracheostomy. Overall, there were 130 procedures completed that can be performed by a general surgeon in addition to the 122 difficult intubations. These procedures included recannulation of a tracheostomy, operative intervention, new emergent tracheostomy or cricothyroidotomy, thoracostomy tube placement, initiation of extracorporeal membrane oxygenation, and pericardiocentesis. CONCLUSION Highly technical procedures are common during an ARR, including procedures related to tracheostomies. Surgeons possess a comprehensive skill set that is unique and comprehensive with respect to airway emergencies. This distinctive skill set creates an important role within the ARR team to perform these urgent technical procedures. LEVEL OF EVIDENCE Epidemiologic/prognostic, level III.

Abstract
Many guidelines consider supraglottic airway use to be an aerosol-generating procedure. This status requires increased levels of personal protective equipment, fallow time between cases and results in reduced operating theatre efficiency. Aerosol generation has never been quantitated during supraglottic airway use. To address this evidence gap, we conducted real-time aerosol monitoring (0.3-10-µm diameter) in ultraclean operating theatres during supraglottic airway insertion and removal. This showed very low background particle concentrations (median (IQR [range]) 1.6 (0-3.1 [0-4.0]) particles.l-1 ) against which the patient's tidal breathing produced a higher concentration of aerosol (4.0 (1.3-11.0 [0-44]) particles.l-1 , p = 0.048). The average aerosol concentration detected during supraglottic airway insertion (1.3 (1.0-4.2 [0-6.2]) particles.l-1 , n = 11), and removal (2.1 (0-17.5 [0-26.2]) particles.l-1 , n = 12) was no different to tidal breathing (p = 0.31 and p = 0.84, respectively). Comparison of supraglottic airway insertion and removal with a volitional cough (104 (66-169 [33-326]), n = 27), demonstrated that supraglottic airway insertion/removal sequences produced <4% of the aerosol compared with a single cough (p < 0.001). A transient aerosol increase was recorded during one complicated supraglottic airway insertion (which initially failed to provide a patent airway). Detailed analysis of this event showed an atypical particle size distribution and we subsequently identified multiple sources of non-respiratory aerosols that may be produced during airway management and can be considered as artefacts. These findings demonstrate supraglottic airway insertion/removal generates no more bio-aerosol than breathing and far less than a cough. This should inform the design of infection prevention strategies for anaesthetists and operating theatre staff caring for patients managed with supraglottic airways.

Abstract
BACKGROUND The current study explores the trends in the application of combat casualty care following the publication of clinical practice guidelines (CPGs) in five domains for 13 years. METHODS The Israel Defense Forces Trauma Registry was used to assess practice and adherence to guidelines in five domains: (a) crystalloid transfusions, (b) tranexamic acid use, (c) freeze-dried plasma use, (d) chest decompression, and (e) airway management. All patients injured between January 2006 and December 2018 were included in the analysis. Trends were analyzed and presented monthly using linear regression and were compared using the Chow test. RESULTS The mean ± SD crystalloid volume transfused decreased from 1,179 ± 653 mL in 2006 to 466 ± 202 mL in 2018 (B = 0.016, 0.006-0.044). The proportion of patients with an indication treated with tranexamic acid dropped from 8% (238 of 2,979 patients) to 2.5% (60 of 2,356 patients) following the stricter guideline's publication. Freeze-dried plasma administration in indicated casualties rose from 12.5% in 2013 to 48% in 2018 (B = 1.63, 1.3-2.05). The overall proportion of casualties undergoing chest decompression rose from 1% (61 of 6,036 casualties) to 1.5% (155 of 10,493 casualties) following the release of a new CPG in 2012 (p = 0.013). There were no significant trends in intubation ratios before (B = 0.987, 0.953-1.02) or after 2012 (B = 10.2, 0.996-1.05). CONCLUSION Some aspects demonstrate the desired trends in response to new CPGs; in others, initial improvement is achieved but followed by stagnation. In some medical care aspects, completely unexpected and undesirable trends are observed. Every change and update in CPGs should be based on reliable data. The effect of every change must be monitored carefully to ensure adequate adherence to lifesaving guidelines. LEVEL OF EVIDENCE Epidemiological study, level IV.

Abstract
BACKGROUND A 'cannot intubate, cannot oxygenate' (CICO) situation is rare in paediatric anaesthesia, but can always occur in children under certain emergency situations. There is a paucity of literature on specific procedures for securing an emergency invasive airway in children younger than 6 yr. A modified emergency front of neck access (eFONA) technique using a rabbit cadaver model was developed to teach invasive airway protection in a CICO situation in children. METHODS After watching an instructional video of our eFONA technique (tracheotomy, intubation with Frova catheter over which a tracheal tube is inserted), 29 anaesthesiologists performed two separate attempts on rabbit cadavers. The primary outcome was the success rate and the performance time overall and in subgroups of trained and untrained participants. RESULTS The overall success rate across 58 tracheotomies was 95% and the median performance time was 67 s (95% confidence interval [CI], 56-76). Performance time decreased from the first to the second attempt from 72 s (95% CI, 57-81) to 61 s (95% CI, 50-81). Performance time was 59 s (95% CI, 49-79) for untrained participants and 72 s (95% CI, 62-81) for trained participants. Clinical experience and age of the participants was not correlated with performance time, whereas the length of the tracheotomy incision showed a significant correlation (P=0.006). CONCLUSION This eFONA training model for children facilitates rapid skill acquisition under realistic anatomical conditions to perform an emergency invasive airway in children younger than 2 yr.

Abstract
It is impossible to secure the airway of a patient with "neck-only" breathing transorally or transnasally. Surgical removal of the larynx (laryngectomy) or tracheal rerouting (tracheoesophageal diversion or laryngotracheal separation) creates anatomic discontinuity. Misguided attempts at oral intubation of neck breathers may cause hypoxic brain injury or death. We present national data from the American Academy of Otolaryngology-Head and Neck Surgery, the American Head and Neck Society, and the United Kingdom's National Reporting and Learning Service. Over half of US otolaryngologist respondents reported instances of attempted oral intubations among patients with laryngectomy, with a mortality rate of 26%. UK audits similarly revealed numerous resuscitation efforts where misunderstanding of neck breather status led to harm or death. Such data underscore the critical importance of staff education, patient engagement, effective signage, and systems-based best practices to reliably clarify neck breather status and provide necessary resources for safe patient airway management.

Abstract
Current evidence suggests that coronavirus disease 2019 (COVID-19) spread occurs via respiratory droplets (particles >5 µm) and possibly through aerosol. The rate of transmission remains high during airway management. This was evident during the 2003 severe acute respiratory syndrome epidemic where those who were involved in tracheal intubation had a higher risk of infection than those who were not involved (odds ratio 6.6). We describe specific airway management principles for patients with known or suspected COVID-19 disease for an array of critical care and procedural settings. We conducted a thorough search of the available literature of airway management of COVID-19 across a variety of international settings. In addition, we have analyzed various medical professional body recommendations for common procedural practices such as interventional cardiology, gastroenterology, and pulmonology. A systematic process that aims to protect the operators involved via appropriate personal protective equipment, avoidance of unnecessary patient contact and minimalization of periprocedural aerosol generation are key components to successful airway management. For operating room cases requiring general anesthesia or complex interventional procedures, tracheal intubation should be the preferred option. For interventional procedures, when tracheal intubation is not indicated, cautious conscious sedation appears to be a reasonable approach. Awake intubation should be avoided unless it is absolutely necessary. Extubation is a high-risk procedure for aerosol and droplet spread and needs thorough planning and preparation. As updates and modifications in the management of COVID-19 are still evolving, local guidelines, appraised at regular intervals, are vital in optimizing clinical management.

Abstract
BACKGROUND The screening tests used for pre-operative evaluation of airway to predict difficult laryngoscopy and intubation have variable diagnostic accuracy. The unanticipated poor laryngeal view is gold standard for defining difficult intubation. We aimed to find out the prevalence of difficult laryngoscopy and intubation, which airway parameter better predicts difficult intubation and whether difficult laryngoscopy is associated with difficult intubation or not. METHODS This analytic cross sectional study was conducted in 665 ASA I/II adult patients, aged 18-65, without obvious airway pathology undergoing elective surgery under general anesthesia. The pre-operative screening tests included mouth opening, modified mallampatti, ratio of height to thyromental distance, sternomentaldistance and upper lip bite test. Cormack-Lehane grade III/ IV was defined as difficult laryngoscopy and potentially difficult intubation. Sensitivity, specificity, positive predictive value, negative predictive value, accuracy and area under curve at 95% confidence interval was calculated for all five screening tests. RESULTS The prevalence of difficult laryngoscopy and intubation was 6.6% (44 cases). The upper lip bite test because of its highest specificity, positive predictive value, negative predictive value, accuracy and area under curve (99.7%; 93.9%; 99.7%; 95.2%; 85.1% respectively) with moderate level of sensitivity (70.5%) was better predictor of difficult intubation than other tests. The difficult laryngoscopy was associated with difficult intubation (p=0.00). CONCLUSIONS The prevalence of difficult laryngoscopy and intubation was 6.6%.The upper lip bite test was a better predictor of difficult intubation and there was a significant association of difficult laryngoscopy with difficult intubation.

Abstract
INTRODUCTION Airway compromise is the second leading cause of potentially survivable death on the battlefield. The purpose of this study was to better understand wartime prehospital airway patients. MATERIALS AND METHODS The Role 2 Database (R2D) was retrospectively reviewed for adult patients injured in Afghanistan between February 2008 and September 2014. Of primary interest were prehospital airway interventions and mortality. Prehospital combat mortality index (CMI-PH), hemodynamic interventions, injury mechanism, and demographic data were also included in various statistical analyses. RESULTS A total of 12,780 trauma patients were recorded in the R2D of whom 890 (7.0%) received prehospital airway intervention. Airway intervention was more common in patients who ultimately died (25.3% vs. 5.6%); however, no statistical association was found in a multivariable logistic regression model (OR 1.28, 95% CI 0.98-1.68). Compared with U.S. military personnel, other military patients were more likely to receive airway intervention after adjusting for CMI-PH (OR 1.33, 95% CI 1.07-1.64). CONCLUSIONS In the R2D, airway intervention was associated with increased odds of mortality, although this was not statistically significant. Other patients had higher odds of undergoing an airway intervention than U.S. military. Awareness of these findings will facilitate training and equipment for future management of prehospital/prolonged field care airway interventions.

Abstract
This 2019 focused update to the American Heart Association pediatric advanced life support guidelines follows the 2018 and 2019 systematic reviews performed by the Pediatric Life Support Task Force of the International Liaison Committee on Resuscitation. It aligns with the continuous evidence review process of the International Liaison Committee on Resuscitation, with updates published when the International Liaison Committee on Resuscitation completes a literature review based on new published evidence. This update provides the evidence review and treatment recommendations for advanced airway management in pediatric cardiac arrest, extracorporeal cardiopulmonary resuscitation in pediatric cardiac arrest, and pediatric targeted temperature management during post-cardiac arrest care. The writing group analyzed the systematic reviews and the original research published for each of these topics. For airway management, the writing group concluded that it is reasonable to continue bag-mask ventilation (versus attempting an advanced airway such as endotracheal intubation) in patients with out-of-hospital cardiac arrest. When extracorporeal membrane oxygenation protocols and teams are readily available, extracorporeal cardiopulmonary resuscitation should be considered for patients with cardiac diagnoses and in-hospital cardiac arrest. Finally, it is reasonable to use targeted temperature management of 32°C to 34°C followed by 36°C to 37.5°C, or to use targeted temperature management of 36°C to 37.5°C, for pediatric patients who remain comatose after resuscitation from out-of-hospital cardiac arrest or in-hospital cardiac arrest.

Abstract
OBJECTIVE To characterise intubation practices in Australian and New Zealand intensive care units (ICUs) and investigate clinician support for establishing airway management guidelines in Australian and New Zealand ICUs. DESIGN An online survey was designed, piloted and distributed to members of the mailing list of the Australian and New Zealand Intensive Care Society (ANZICS), with medical members invited to participate. Respondents were excluded if their primary practice was in paediatric ICUs. MAIN OUTCOME MEASURES Data collected included the respondents' demographics and airway management practices and whether respondents supported the formulation of Australian and New Zealand intubation guidelines for critically ill patients in ICU and mandatory airway management training for Fellows of the College of Intensive Care Medicine of Australia and New Zealand (CICM). RESULTS Over a quarter of ANZICS medical members completed the survey (203/756, 27%), of which 166 (22%) were included in the analysis. The majority of respondents were male (80%), consultant intensivists (80%), and from tertiary centres (59%). Seventeen per cent worked concurrently in ICU and anaesthesia, and 52% had not completed formal airway training within the previous 3 years. Propofol was the preferred induction agent (67%) and rocuronium was the preferred neuromuscular blocking agent (58%). Videolaryngoscopy was immediately available in 97% of the ICUs and used first-line by 43% of respondents. Sixty-one per cent of respondents were in favour of the development of Australian and New Zealand ICU airway management guidelines, and 80% agreed that airway management training should be mandatory for CICM Fellows. CONCLUSION Variation of practices in intubation was noted in the participants. Approximately 61% of respondents supported the development of Australian and New Zealand ICU airway management guidelines, and 80% supported mandatory airway management training.

Abstract
First responders need hands-on experience with pediatric airway management, but the impact of a learner program in the operating room (OR) is unknown. We developed, implemented, and evaluated a pediatric airway "rotator" (PAR) program for 8 multidisciplinary groups to obtain this experience. This quality improvement pilot was conducted in the pediatric ORs from November 2017 to January 2018. We surveyed learner group leaders and anesthesia teachers about their PAR airway management expectations and developed a universal set of prerequisites, objectives, and simulation experiences. Airway management skills were assessed in a group of PARs at baseline. During implementation, another group of PARs completed prerequisites and reviewed objectives before coming to the OR for simu-lation using an infant mannequin. Then they entered the OR for "live" airway management. A comparison of preintervention and postintervention skills suggested an improvement in performance for most airway management domains except laryngeal mask airway insertion, which stayed about the same, and intubation, which decreased in the postintervention group. In the postassessment surveys, the PARs indicated that the interventions were helpful to their learning, and the anesthesia teachers' responses indicated that the primary goals to improve PARs' preparedness, airway management, and communication skills were achieved.

Abstract
BACKGROUND Effective and timely airway management is a priority for sick and injured patients. The benefit and conduct of pre-hospital emergency anaesthesia (PHEA) and advanced airway management remains controversial but there are a proportion of critically ill and injured patients who require urgent advanced airway management prior to hospital arrival. This document provides current best practice advice for the provision of PHEA and advanced airway management. METHOD This best practice advice was developed from EHAC Medical Working Group enforced by pre-hospital critical care experts. The group used a nominal group technique to establish the current best practice for the provision of PHEA and advanced airway management. The group met on three separate occasions to discuss and develop the guideline. All members of the working party were able to access and edit the guideline online. RESULTS This EHAC best practice advice covers all areas of PHEA and advanced airway management and provides up to date evidence of current best practice. CONCLUSION PHEA and advanced airway management are complex interventions that should be delivered by appropriately trained personnel using a well-rehearsed approach and standardised equipment. Where advanced airway interventions cannot be delivered, careful attention should be given to applying basic airway interventions and ensuring their effectiveness at all times.

Abstract
INTRODUCTION Multiple formulae have been proposed for calculating orotracheal depth for paediatric intubation. However, literature on the validation of these formulae in the emergency department setting is limited. Three methods described in the local Advanced Paediatric Life Support curriculum include the Broselow tape, endotracheal tube (ETT) size x 3, and the age-based formula of age divided by 2, add 12. We aimed to determine their accuracy. MATERIALS AND METHODS Patients with intubation performed in the Children's Emergency from 1 January 2009 to 31 December 2013 were included in this retrospective observational study. The depths of ETT placement based on the formulae were calculated from the actual depth of ETT. ETT position between T2 to T4 vertebral bodies of the chest radiograph was taken as the reference position for radiological accuracy. RESULTS ETT size x 3 has the highest accuracy of 76.5%, as compared to 67.9% for age-based formula and 63.5% for Broselow tape. When the formulae were inaccurate, Broselow tape often predicted a depth that was too shallow as compared to ETT size x 3 (P = 0.006) and age-based formula (P = 0.011). The accuracy of Broselow tape was not uniform across the age groups, with highest accuracy in patients 1 to 8 years old. ETT size x 3 had the highest accuracy in patients weighing more than 25 kg. CONCLUSION ETT size x 3 was superior for determining orotracheal intubation depth but cannot preclude the confirmation of appropriate placement of ETT by auscultation and chest radiograph.

Abstract
Auto-titrating noninvasive ventilation (NIV) has been developed as a new mode applying variable expiratory-positive airway pressure (EPAP) in addition to variable inspiratory pressures (IPAP), both to deliver targeted tidal volume (VT) and to eliminate upper airway resistance. The purpose of this study is to evaluate whether NIV with auto-titrating mode will decrease more PaCO2 within a shorter time compared to volume-assured mode in hypercapnic intensive care unit (ICU) patients. The hypercapnic respiratory failure patients treated with average volume assured pressure support- automated EPAP mode (group1) were compared with those treated with average volume-assured pressure support mode (group2). Two groups were matched with each other according to baseline diagnoses, demographic characteristics, arterial blood gas values, target VT settings and daily NIV usage times. Built-in software was used to gather the ventilatory parameters. Twenty-eight patients were included in group 1, and 22 in group 2. The decrease in PaCO2 had been achieved within a shorter time period in group 1 (p < 0.05). This response was more pronounced within the first 6 h (mean reduction in PaCO2 was 7 ± 7 mmHg in group 1 and 2 ± 5 mmHg in group 2, p = 0.025), and significantly greater reductions in PaCO2 (18 ± 11 mmHg in group 1 and 9 ± 8 mmHg in group 2, p = 0.008) and plasma HCO3 levels (from 32 to 30 mEq and from 35 to 35 mEq, p = 0.007) took place within first 4 days. While mean IPAP was similar in both groups, maximum EPAP, mean VT and leak were significantly higher in group 1 than in group 2 (p < 0.05). Results of this preliminary study suggest that, this new auto-titrating NIV mode may provide additional benefit on volume-assured mode in decreasing PaCO2 more efficiently and rapidly in hypercapnic ICU patients.

Abstract
A decade ago the Difficult Airway Response Team (DART) program was created at The Johns Hopkins Hospital as a multidisciplinary effort to address airway-related adverse events in the nonoperative setting. Root cause analysis of prior events indicated that a major factor in adverse patient outcomes was lack of a systematic approach for responding to difficult airway patients in an emergency. The DART program encompasses operational, safety, and educational initiatives and has responded to approximately 1000 events since its initiation, with no resultant adult airway-related adverse events or morbidity. This article provides lessons learned and recommendations for initiating a DART program.

Abstract
The difficult airway constitutes a continuous challenge for anesthesiologists. Guidelines and algorithms are key to preserving patient safety, by recommending specific plans and strategies that address predicted or unexpected difficult airway. However, there are currently no "gold standard" algorithms or universally accepted standards. The aim of this article is to present a synthesis of the recommendations of the main guidelines and difficult airway algorithms.

Abstract
The purpose of this investigation was to investigate the association between first attempt success and intubation-related complications in the Intensive Care Unit after the widespread adoption of video laryngoscopy. We further sought to characterize and identify the predictors of complications that occur despite first attempt success. This was a prospective observational study of consecutive intubations performed with video laryngoscopy at an academic medical Intensive Care Unit. Operator, procedural, and complication data were collected. Multivariable logistic regression was used to examine the relationship between the intubation attempts and the occurrence of one or more complications. A total of 905 patients were intubated using a video laryngoscope. First attempt success occurred in 739 (81.7 %), whereas >1 attempt was needed in 166 (18.3 %). One or more complications occurred in 146 (19.8 %) of those intubated on the first attempt versus 107 (64.5 %, p < 0.001) of those requiring more than one attempt. Logistic regression analysis shows that >1 attempt is associated with 6.4 (95 % CI 4.4-9.3) times the adjusted odds of at least one complication. Pre-intubation predictors of at least one complication despite first attempt success include vomit or edema in the airway as well as the presence of hypoxemia or hypotension. There are increased odds of complications with even a second attempt at intubation in the Intensive Care Unit. Complications occur frequently despite a successful first attempt, and as such, the goal of airway management should not be simply first attempt success, but instead first attempt success without complications.

Abstract
A difficult airway may lead to hypoxia and brain damage. The WEI Nasal Jet Tube (WNJ) is a new nasal pharyngeal tube that applies supraglottic jet oxygenation and ventilation (SJOV) for patients during tracheal intubation without the need for mask ventilation. We evaluated the effectiveness and safety of SJOV-assisted fibre-optic bronchoscopy (FOB) using the WNJ in the management of difficult tracheal intubations. A total of 50 adult patients with Cormack-Lehane grade ≥3 and general anesthesia with tracheal intubation were randomly assigned to either the laryngeal mask airway (LMA) or WNJ groups. The primary outcome was the percentage of patients with SpO2 values lower than 94 % during intubation. The proportion of successful intubations, total time of intubation, and associated complications were also recorded. The percentage of patients with SpO2 values lower than 94 % during intubation was significantly higher in the LMA group (25 % in the LMA vs. 0 % in the WNJ, P = 0.01). Although there were no statistically significant differences in the total success rates of intubation, the first-attempt success rate was significantly higher in the WNJ group (100 vs. 79.2 %, P = 0.02). The total time required for intubation with the WNJ was shorter than that of the LMA (73.4 vs. 99.5 s, P < 0.001), although the duration of fibre-optic intubation was similar. The incidence of complications was similar between the two groups. SJOV-assisted FOB using the WNJ improved oxygenation and successful tracheal intubation in the management of difficult airways. This technique can be used as an alternative approach to improve success and minimize hypoxia during difficult airway management.

Abstract
Pre-hospital emergency anaesthesia with oral tracheal intubation is the technique of choice for trauma patients who cannot maintain their airway or achieve adequate ventilation. It should be carried out as soon as safely possible, and performed to the same standards as in-hospital emergency anaesthesia. It should only be conducted within organisations with comprehensive clinical governance arrangements. Techniques should be straightforward, reproducible, as simple as possible and supported by the use of checklists. Monitoring and equipment should meet in-hospital anaesthesia standards. Practitioners need to be competent in the provision of in-hospital emergency anaesthesia and have supervised pre-hospital experience before carrying out pre-hospital emergency anaesthesia. Training programmes allowing the safe delivery of pre-hospital emergency anaesthesia by non-physicians do not currently exist in the UK. Where pre-hospital emergency anaesthesia skills are not available, oxygenation and ventilation should be maintained with the use of second-generation supraglottic airways in patients without airway reflexes, or basic airway manoeuvres and basic airway adjuncts in patients with intact airway reflexes.

Abstract
Extraglottic airway (EGA) devices have been used by both physicians and prehospital providers for several decades. The original TCCC Guidelines published in 1996 included a recommendation to use the laryngeal mask airway (LMA) as an option to assist in securing the airway in Tactical Evacuation (TACEVAC) phase of care. Since then, a variety of EGAs have been used in both combat casualty care and civilian trauma care. In 2012, the Committee on TCCC (CoTCCC) and the Defense Health Board (DHB) reaffirmed support for the use of supraglottic airway (SGA) devices in the TACEVAC phase of TCCC, but did not recommend a specific SGA based on the evidence available at that point in time. This paper will use the more inclusive term "extraglottic airway" instead of the term "supragottic airway" used in the DHB memo. Current evidence suggests that the i-gel® (Intersurgical Complete Respiratory Systems; http://www.intersurgical.com/info/igel) EGA performs as well or better than the other EGAs available and has other advantages in ease of training, size and weight, cost, safety, and simplicity of use. The gel-filled cuff in the i-gel both eliminates the need for cuff pressure monitoring during flight and reduces the risk of pressure-induced neuropraxia to cranial nerves in the oropharynx and hypopharynx as a complication of EGA use. The i-gel thus makes the medic's tasks simpler and frees him or her from the requirement to carry a cuff manometer as part of the medical kit. This latest change to the TCCC Guidelines as described below does the following things: (1) adds extraglottic airways (EGAs) as an option for airway management in Tactical Field Care; (2) recommends the i-gel as the preferred EGA in TCCC because its gel-filled cuff makes it simpler to use than EGAs with air-filled cuffs and also eliminates the need for monitoring of cuff pressure; (3) notes that should an EGA with an air-filled cuff be used, the pressure in the cuff must be monitored, especially during and after changes in altitude during casualty transport; (4) emphasizes COL Bob Mabry's often-made point that extraglottic airways will not be tolerated by a casualty unless he or she is deeply unconscious and notes that an NPA is a better option if there is doubt about whether or not the casualty will tolerate an EGA; (5) adds the use of suction as an adjunct to airway management when available and appropriate (i.e., when needed to remove blood and vomitus); (6) clarifies the wording regarding cervical spine stabilization to emphasize that it is not needed for casualties who have sustained only penetrating trauma (without blunt force trauma); (7) reinforces that surgical cricothyroidotomies should not be performed simply because a casualty is unconscious; (8) provides a reminder that, for casualties with facial trauma or facial burns with suspected inhalation injury, neither NPAs nor EGAs may be adequate for airway management, and a surgical cricothyroidotomy may be required; (9) adds that pulse oximetry monitoring is a useful adjunct to assess airway patency and that capnography should also be used in the TACEVAC phase of care; and (10) reinforces that a casualty's airway status may change over time and that he or she should be frequently reassessed.

Abstract
BACKGROUND Advancements in airway management have made the practice of blind nasal intubation obsolete. We report on successful blind nasal intubation performed with the help of capnography and real-time ultrasonography in two patients with tempormandibular joint ankylosis. CASE REPORT Blind nasal intubation was performed in a 12-year-old patient and a 17-year old patient under general anesthesia with spontaneous respiration. Capnography was used as an aid during insertion and dynamic ultrasonography was performed to guide and confirm proper tracheal tube placement. Use of capnography helps in following the correct path toward the glottic opening, with quick detection of any obstruction, and with confirmation of final placement of the tracheal tube. Ultrasonography aids with entry into the glottis and with identifying the correct placement. We recommend the use of this modified blind nasal intubation in patients with limited mouth opening when equipment, such as a fiberoptic scope, is not available or is nonfunctional in the emergency department. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Adapting this technique will add to the armamentarium available for airway management in emergency medicine, particularly in maxillofacial injuries with limited mouth opening.

Abstract
Critically ill patients undergoing emergent intubation are at risk of oxygen desaturation during the management of their airway. Patients with intracranial hemorrhage (ICH) are particularly susceptible to the detrimental effects of hypoxemia. Apneic oxygenation (AP OX) may be able to reduce the occurrence of oxygen desaturation during the emergent intubation of these patients. We sought to assess the effect AP OX on oxygen desaturation during the rapid sequence intubation (RSI) of patients with ICH in the emergency department (ED). We prospectively collected data on all patients intubated in an urban academic ED over the 2-year period from July 1, 2013 to June 30, 2015. Following each intubation, the operator completed a standardized continuous quality improvement (CQI) data form, which included information on patient, operator and intubation characteristics. Operators recorded data on the use of AP OX, the oxygen flow rate used for AP OX, and the starting and lowest saturations during intubation. Adult patients with ICH who underwent RSI by emergency medicine (EM) residents were included in the analyses. The primary outcome variable was any oxygen saturation <90 % during the intubation. We performed a backward stepwise multivariate logistic regression analysis to identify variables associated with oxygen desaturation. The primary independent variable of interest was the use of AP OX during the intubation. Inclusion criteria for the study was met by 127 patients. AP OX was used in 72 patients (AP OX group) and was not used in 55 patients (NO AP OX group). The incidence of desaturation was 5/72 (7 %) in the AP OX group and was 16/55 (29 %) in the NO AP OX group. In the multivariate logistic regression analysis the use of AP OX was associated with a reduced odds of desaturation (aOR 0.13; 95 % CI 0.03-0.53). Patients with ICH who received AP OX during RSI in the ED were seven times less likely to have an oxygen saturation of <90 % during the intubation compared to patients who did not receive AP OX. AP OX is a simple intervention that may minimize the risk of oxygen desaturation during the RSI of patients with ICH.

Abstract
INTRODUCTION Difficult airway management is associated with an increased risk of morbidity and mortality. Several preoperative risk factors associated with airway management difficulties have been proposed; however, no clear guideline for airway assessments exists. We therefore hypothesised that Danish airway assessment was lacking uniformity. We aimed to examine whether multivariable risk assessment tools and predictors for difficult intubation and mask ventilation were used systematically. METHODS Heads of anaesthesia departments were sent a six-question survey at the beginning of 2012. We asked if systematic risk assessment tools, particularly the Simplified Airway Risk Index (SARI), and predictors for difficult intubation and mask ventilation were used. Additionally, we asked if any risk factors were pre-printed on the anaesthesia record. RESULTS In all, 29 of 31 (94%) departments responded. The SARI was implemented in 8 of 29 (28%, 95% confidence interval (CI): 15-46%) departments with major regional differences. There was no significant association between using the SARI and a reduced number of unanticipated difficult intubation (p = 0.06). Mallampati classification (95.2%, 95% CI: 77.3-99.2%), history of airway management difficulties (85.7%, 95% CI: 65.4-95.0%), ability to prognath (81.0%, 95% CI: 60.0-92.3%) and neck mobility (81.0%, 95% CI: 60.0-92.3%) were the main predictors registered. CONCLUSION We found considerable inter-departmental variance in the standards employed for airway assessment and no uniform pattern in the registration of risk factors for airway management difficulties. Better prediction of difficult intubation could not be detected in departments that used the SARI. FUNDING none. TRIAL REGISTRATION not relevant.

Abstract
Nonanesthesiologist administered propofol (NAAP) sedation for flexible bronchoscopy is controversial, because there is no established airway management (AM) training for pulmonologists. The aim was to investigate the performance and acceptance of a proposed AM algorithm and training for pulmonologists performing NAAP sedation. The algorithm includes using 3 maneuvers including bag mask ventilation (BMV), laryngeal tube (LT), and needle cricothyrotomy (NCT). During training (consisting of 2 sessions with a break of 9 weeks in between), these maneuvers were demonstrated and exercised, followed by 4 consecutive attempts to succeed with each of these devices. The primary outcome was the improvement of completion time needed for a competent airway. Secondary outcomes were the trainees' overall reactions to the training and algorithm, and the perceptions of psychological safety (PS). The 23 staff members of the Department of Pulmonology performed a total of 552 attempts at AM procedures (4 attempts at each of the 3 maneuvers in 2 sessions), and returned a total of 42 questionnaires (4 questionnaires were not returned). Median completion times of LT and NCT improved significantly between Sessions 1 and 2 (P = 0.005 and P = 0.04, respectively), whereas BMV was only marginally improved (P = 0.05). Trainees perceived training to be useful and expressed satisfaction with this training and the algorithm. The perception of PS increased after training. An AM algorithm and training for pulmonologists leads to improved technical AM skills, and is considered useful by trainees and raised their perception of PS during training. It thus represents a promising program.

Abstract
PURPOSE Analyzing preventable and potentially preventable deaths is a well-known procedure for improving trauma care. This study analyzes preventable and potentially preventable deaths in German trauma patients. METHODS Patients aged between 16 and 75 years with an Injury Severity Score >15 who were primary admitted from July 2002 to December 2011 were analyzed in this study. Data from the patients' hospital records were retrospectively analyzed, and cases were categorized as preventable, potentially preventable, and non-preventable deaths. In addition, trauma management was screened for errors. RESULTS 2304 patients were admitted from July 2002 to December 2011. 763 of which fulfilled the defined criteria. The mortality rate was 25.3 %. Eight cases (4.2 %) were declared as preventable deaths and 31 cases (16.1 %) as potentially preventable deaths. The most common errors in preclinical trauma care related to airway management. The main clinical error was insufficient hemorrhage control. Fluid overload from infusion was the second most common fault in both. CONCLUSIONS Preventable and potentially preventable errors still occur in the treatment of severely injured patients. Errors in hemorrhage control and airway management are the most common human treatment errors. The knowledge of these errors could help to improve trauma care in the future.

Abstract
These guidelines provide a strategy to manage unanticipated difficulty with tracheal intubation. They are founded on published evidence. Where evidence is lacking, they have been directed by feedback from members of the Difficult Airway Society and based on expert opinion. These guidelines have been informed by advances in the understanding of crisis management; they emphasize the recognition and declaration of difficulty during airway management. A simplified, single algorithm now covers unanticipated difficulties in both routine intubation and rapid sequence induction. Planning for failed intubation should form part of the pre-induction briefing, particularly for urgent surgery. Emphasis is placed on assessment, preparation, positioning, preoxygenation, maintenance of oxygenation, and minimizing trauma from airway interventions. It is recommended that the number of airway interventions are limited, and blind techniques using a bougie or through supraglottic airway devices have been superseded by video- or fibre-optically guided intubation. If tracheal intubation fails, supraglottic airway devices are recommended to provide a route for oxygenation while reviewing how to proceed. Second-generation devices have advantages and are recommended. When both tracheal intubation and supraglottic airway device insertion have failed, waking the patient is the default option. If at this stage, face-mask oxygenation is impossible in the presence of muscle relaxation, cricothyroidotomy should follow immediately. Scalpel cricothyroidotomy is recommended as the preferred rescue technique and should be practised by all anaesthetists. The plans outlined are designed to be simple and easy to follow. They should be regularly rehearsed and made familiar to the whole theatre team.

Abstract
Numerous studies addressing airway management in OHCA have shown a strong association between improved survival with treatment using BVM alone rather than with advanced airways. This BVM effect appears to persist despite variations in geographical region, patient population, and CPR quality. The underlying cause of this phenomenon remains to be determined. Of note, the survival benefit with BVM alone vs. advanced airways doesn't appear in the pediatric population in the papers reviewed by the authors. The authors recommend that a prospective randomized study be conducted in order to explore this finding and to attempt to determine its causation.

Abstract
BACKGROUND Trauma represents a challenge to healthcare systems worldwide, particularly in low-and middle-income countries. Positive effects can be achieved by improving trauma care at the scene of the accident and throughout hospitalization and rehabilitation. Therefore, we assessed the long-term effects of national implementation of a training program for multidisciplinary trauma teams in a southern African country. METHODS From 2007 to 2009, an educational program for trauma, "Better and Systematic Team Training," (BEST) was implemented at all government hospitals in Botswana. The effects were assessed through interviews, a structured questionnaire, and physical inspections using the World Health Organization's "Guidelines for Essential Trauma Care." Data on human and physical resources, infrastructure, trauma administrative functions, and quality-improvement activities before and at 2-year follow-up were compared for all 27 government hospitals. RESULTS A majority of hospitals had formed local trauma organizations; half were performing multidisciplinary trauma simulations and some had organized multidisciplinary trauma teams with alarm criteria. A number of hospitals had developed local trauma guidelines and local trauma registries. More equipment for advanced airway management and stiff cervical collars were available after 2 years. There were also improvements in the skills necessary for airway and breathing management. The most changes were seen in the northern region of Botswana. CONCLUSIONS Implementation of BEST in Botswana hospitals was associated with several positive changes at 2-year follow-up, particularly for trauma administrative functions and quality-improvement activities. The effects on obtaining technical equipment and skills were moderate and related mostly to airway and breathing management.

Abstract
OBJECTIVE To evaluate whether the use of a GlideScope video laryngoscope (GVL) improves first-attempt intubation success compared with the Macintosh laryngoscope (MAC) in the emergency department (ED). DESIGN A propensity score-matched analysis of data from a prospective multicentre ED airway registry-the Korean Emergency Airway Management Registry (KEAMR). SETTING 4 academic EDs located in a metropolitan city and a province in South Korea. PARTICIPANTS A total of 4041 adult patients without cardiac arrest who underwent emergency intubation from January 2007 to December 2010. OUTCOME MEASURES The primary and secondary outcomes were successful first intubation attempt and intubation failure, respectively. To reduce the selection bias and potential confounding effects, we rigorously adjusted for the baseline differences between two groups using a propensity score matching. RESULTS Of the 4041 eligible patients, a GVL was initially used in 540 patients (13.4%). Using 1:2 propensity score matching, 363 and 726 patients were assigned to the GVL and MAC groups, respectively. The adjusted relative risks (95% CIs) for the first-attempt success rates with a GVL compared with a MAC were 0.76 (0.56 to 1.04; p=0.084) and the respective intubation failure rates 1.03(0.99 to 1.07; p=0.157). Regarding the subgroups, the first-attempt success of the senior residents and attending physicians was lower with the GVL (0.47 (0.23 to 0.98), p=0.043). In the patients with slight intubation difficulty, the first-attempt success was lower (0.60 (0.41 to 0.88), p=0.008) and the intubation failure was higher with the GVL (1.07 (1.02 to 1.13), p=0.008). CONCLUSIONS In this propensity score-matched analysis of data from a prospective multicentre ED airway registry, the overall first-attempt intubation success and failure rates did not differ significantly between GVL and MAC in the ED setting. Further randomised controlled trials are needed to confirm our findings.
