RÉSUMÉ
BACKGROUND: Prehospital airway management remains crucial with regard to the quality and safety of emergency medical service (EMS) systems worldwide. In 2007, the benchmark study by Timmermann et al. hit the German EMS community hard by revealing a significant rate of undetected oesophageal intubations leading to an often-fatal outcome. Since then, much attention has been given to guideline development and training. This study evaluated the incidence and special circumstances of tube misplacement as an adverse peri-intubation event from a Helicopter Emergency Medical Services perspective. METHODS: This was a retrospective analysis of a German helicopter-based EMS database from January 1, 2012, to December 31, 2020. All registered patients were included in the primary analysis. The results were analysed using SPSS 27.0.1.0. RESULTS: Out of 227,459 emergency medical responses overall, a total of 18,087 (8.0%) involved invasive airway management. In 8141 (45.0%) of these patients, airway management devices were used by ground-based EMS staff, with an intubation rate of 96.6% (n = 7861), and alternative airways were used in 3.2% (n = 285). Overall, the rate of endotracheal intubation success was 94.7%, while adverse events in the form of tube misplacement were present in 5.3%, with a 1.2% rate of undetected oesophageal intubation. Overall tube misplacement and undetected oesophageal intubation occurred more often after intubation was carried out by paramedics (10.4% and 3.6%, respectively). In view of special circumstances, those errors occurred more often in the presence of trauma or cardiopulmonary resuscitation, with rates of 5.6% and 6.4%, respectively. Difficult airways with a Cormack 4 status were present in 2.1% (n = 213) of HEMS patients, accompanied by three or more intubation attempts in 5.2% (n = 11). CONCLUSIONS: Prehospital airway management success has improved significantly in recent years. However, adverse peri-intubation events such as undetected oesophageal intubation remain a persistent threat to patient safety. TRIAL REGISTRATION: The study was registered in the German Register for Clinical Studies (number DRKS00028068).

Tracheal intubation is a fundamental facet of airway management, for which the importance of achieving success at the first attempt is well recognized. Failure to do so can lead to significant morbidity and mortality if there is inadequate patient oxygenation by alternate means. The evidence supporting the benefits of a videolaryngoscope in attaining this objective is now overwhelming (in adults). This has led to its increasing recognition in international airway management guidelines and its promotion from an occasional airway rescue tool to the first-choice device during routine airway management. However, usage in clinical practice does not currently reflect the increased worldwide availability that followed the upsurge in videolaryngoscope purchasing during the coronavirus disease 2019 pandemic. There are a number of obstacles to widespread adoption, including lack of adequate training, fears over de-skilling at direct laryngoscopy, equipment and cleaning costs, and concerns over the environmental impact, among others. It is now clear that in order for patients to benefit maximally from the technology and for airway managers to fully appreciate its role in everyday practice, proper training and education are necessary. Recent research evidence has addressed some existing barriers to default usage, and the emergence of techniques such as awake videolaryngoscopy and video-assisted flexible (bronchoscopic) intubation has also increased the scope of clinical application. Future studies will likely further confirm the superiority of videolaryngoscopy over direct laryngoscopy, therefore, it is incumbent upon all airway managers (and their teams) to gain expertise in videolaryngoscopy and to use it routinely in their everyday practice..

ABSTRACT: Advanced airway management is a skill that is used every day in patient care settings throughout the world. Albeit common, it is not benign. Advanced airway management may either be elective or urgent; in either case, it may result in significant patient morbiidity and mortality. The complications of difficult or failed endotracheal intubation can be severe and include death or permanent neurologic injury. Difficulty or failure with advanced airway management often coincides with the onset of hypoxia. The onset of hypoxia affects both the patient and the airway manager. While hypoxemia may result in dysrhythmias and ultimately cardiac arrest for the patient, it adds time pressure and stress to the airway manager, and thus may impact successful performance. In this review, we will discuss how to identify patients at risk for rapid desaturation during advanced airway management. Additionally, methods of peri-oxygenation throughout the performance of airway management will be discussed.

ABSTRACT: Supraglottic airways have been utilized as an alternative to facemask ventilation and endotracheal intubation and thus have been essential to airway management since their introduction in the late 1980s. This chapter describes basic considerations in their use and an update on current clinical practice, with an emphasis on safe management. The devices have evolved to meet today's clinical airway challenges, and they provide benefits for patients and practitioners.

Awake tracheal intubation (ATI) remains the "gold standard" technique in securing a definitive airway in conscious, self-ventilating patients with predicted or known difficult airways and the procedure is associated with a low failure rate. Since its inception a variety of techniques to achieve ATI have emerged and there have been accompanying advancements in pharmaceuticals and technology to support the procedure. In recent years there has been a growing focus on the planning, training and human factors involved in performing the procedure. The practice of ATI, does however, remain low around 1% to 2% of all intubations despite an increase in those with head and neck pathology. ATI, therefore, presents a skill that is key for the safety of patients but may not be practised with regularity by many anesthetists. In this article we therefore aim to highlight relevant guidance, recent literature and provide an update on the practical methods fundamental for successful ATI. We also discuss the crucial aspects of a safe airway culture and how this can help to embed training and maintenance of skills.

Emergency front-of-neck access refers to all techniques that deliver oxygen into the airway lumen through the anterior neck structures and encompasses access both through the cricothyroid membrane and the tracheal wall. There has yet to be a universal agreement regarding the preferred technique. A surgical incision is currently the most common approach in prehospital and in-hospital care. This review intends to review and summarize the existing clinical, basic science, and societal guidelines for eFONA.

BACKGROUND Submental intubation, a technique often considered a good alternative for managing the airway in challenging maxillofacial surgical scenarios, plays a pivotal role in providing accessibility to the surgical site and ensuring airway safety, particularly in cases involving facial fractures. This innovative approach not only grants surgeons adequate access to the operative field but also mitigates potential complications associated with traditional intubation methods, making it a valuable tool in dealing with complex facial trauma cases. CASE REPORT A 37-year-old man arrived at the Emergency Department (ED) with a severe facial injury caused from a traumatic incident involving a falling concrete wall, resulting in severe facial injuries that included multiple lacerations and abrasions on his face and body. The patient presented with multiple facial and body lacerations and abrasions, necessitating prompt medical intervention. The ED team swiftly treated the facial lacerations, controlled the bleeding, stabilized the patient, and proceeded to secure the airway through orotracheal intubation. Following stabilization, the patient was transferred to the operation theater (OT) for further management of his extensive pan-facial fractures under general anesthesia, utilizing the submental intubation technique for airway management. CONCLUSIONS Despite its limited use, submental intubation is a good option for some maxillofacial surgeries, offering a less intrusive approach to airway management and presenting an alternative pathway to the conventional endotracheal intubation technique. Its ability to streamline procedures, enhance patient outcomes, and reduce complications underscores the importance of considering submental intubation as a valuable tool in dealing with complex maxillofacial cases.

Infants with Pierre Robin sequence present with difficult airways due to their triad of micrognathia, glossoptosis, and cleft palate. This creates a difficult airway to intubate and ventilate. Typically, with various interventions and the growth of the mandible with age, the airway gets easier to manage into adulthood. Surgeries, such as coronoidectomy, have been found to ease the difficulty of intubation in pediatric patients, but the results are not always permanent. We present an adult with Pierre Robin sequence who continued to have a difficult airway, suggesting that airway management does not necessarily improve with age.

INTRODUCTION: Between 2011 and 2014, the Combat Casualty Training Consortium research study sought to evaluate all aspects of combat casualty care, including mortality, with a special focus on the incidence and causes of potentially preventable deaths among American combat fatalities. This study identified a major training gap in critical airway management. Because of the high rate of morbidity and mortality associated with poor or incorrect airway management, an effort to address this training gap was necessary. MATERIALS AND METHODS: This experiment compared the training using the Advanced Joint Airway Management System, a novel high-fidelity airway simulator, relative to one of the most utilized simulators for endotracheal intubation (ETI) via a parallel group randomized control trial design. Before training, participants (n = 19) attempted an ETI on a cadaver using direct laryngoscopy. Performance during the attempt was recorded and scored by trained blinded raters. Participants were then randomly allocated to either novel or conventional training. Post-training, participants completed a second ETI under the same parameters. Analysis was completed via 2 × 2 mixed analysis of variance for (1) ETI Score, (2) Errors, (3) Critical Failures, and (4) Duration, across both the pre- and post-training tests and between the two groups. RESULTS: A priori power analysis required a total sample size of 84 participants in this experimental design. Consequently, this study is under-powered to reach statistical significance. Scores for all trainees did improve with training, yet analyses did not reveal a difference in overall ETI score between the novel and conventional training group, at baseline or at the post-training test (P = .249). CONCLUSION: The Advanced Joint Airway Management System simulator presents a training effect that is comparable to the conventional training model. However, given this study's small sample size, these results must be considered preliminary and further research is merited to draw firm conclusions about its impact on trainee performance. Future studies engaging larger cohorts of trainees and exploring the other capabilities of the Advanced Joint Airway Management System (cricothyroidotomy, needle chess decompression) are needed to further examine the educational potential of this novel airway management training system.

OBJECTIVES: Parturients are at increased risk for difficult airway management with subsequent fetal complications. Videolaryngoscopy was opined to be the new standard of airway care to facilitate orotracheal intubation under urgent care conditions. We examined in parturients requiring general anesthesia for urgent cesarean delivery the association of the type of laryngoscopy technique and time required to facilitate orotracheal intubation with the incidence of subsequent neonatal intensive care unit (NICU) admission. METHODS: Following institutional review board approval, 431 parturients aged 18 years and older who underwent urgent cesarean section requiring general anesthesia were entered into this study. Patient characteristics, maternal comorbidities, and indications for urgent cesarean delivery were collected from the electronic medical records from January 2013 to November 2018. Orotracheal intubation times by type of laryngoscopy (video or direct) and NICU admission rates also were collected. A measure of effect size, risk differences with 95% confidence intervals (CIs), were calculated for the likelihood of NICU admission by difficult orotracheal intubation and by type of laryngoscopy used to secure the airway. RESULTS: Videolaryngoscopy as the primary type of laryngoscopy was used in 24.1% (95% CI 20.3%-28.3%) of general anesthetics. The incidence of difficult orotracheal intubation was 4.4% (95% CI 2.8%-6.7%), with a higher incidence observed with videolaryngoscopy (8.7%) than with direct laryngoscopy (3.1%) and a risk difference of 5.6% (95% CI 0.001%-11.3%). The incidence of NICU admission was 38.4% (95% CI 34.0%-43.1%). Times for successful orotracheal intubation were longer with videolaryngoscopy. Videolaryngoscopy had a higher association for NICU admission (47%) than for direct laryngoscopy (36%), with a risk difference of 11.4% (95% CI 0.01%-22.3%). CONCLUSIONS: Videolaryngoscopy did not decrease the incidence of difficult orotracheal intubation, and it did not decrease the time associated with orotracheal intubation. Videolaryngoscopy was associated with a higher association of NICU admission. These results suggest that videolaryngoscopy does not supplant direct laryngoscopy as the standard of care for orotracheal intubation under urgent care conditions of general anesthesia for cesarean section.

BACKGROUND: Securing the airway in the emergency department (ED) is a high-stakes procedure; however, the primary success and complication rate are largely unknown in Germany. The aim of this study was a retrospective analysis of prospectively collected resuscitation room data for endotracheal intubation (ETI) regarding indications, performance and complications. METHOD: Between 1 January 2020 and 30 June 2023 all ETIs conducted in the ED (Kliniken Maria Hilf, Moenchengladbach, Germany) were analyzed following approval by the ethics committee (EK 23-369). Primary intubations performed by the anesthesiology department were excluded. The core medical team of the ED underwent a six-week training program including a two-week anesthesia rotation prior to performing ETI in the ED. There were standard operating procedures (SOP) for both rapid sequence induction (RSI) and airway exchange with a placed laryngeal tube (LT) utilizing video laryngoscopy (C-Mac, Storz), rocuronium for relaxation and primary intubation with an elastic bougie. The primary success rate, overall success rate and intubation-related complications were analyzed. Additionally, the factor of consultant ED staff and residents was evaluated with respect to the primary success rate. RESULTS: During the study period 499 patients were intubated by the core ED team and 28 patients underwent airway exchange from LT to ETI. Primary success could be achieved in 489/499 (98.0%) ETI and in 25/28 (89.3%) LT exchange patients. Surgically achieved securing of the airway was carried out in 5/527 (0.9%) patients in a cannot intubate situation and 11/527 (2.2%) patients suffered cardiac arrest minutes after the ETI. The overall first pass success rate of endotracheal tube placement was 514/527 (97.4%). The comparison of the primary success of consultants (168/175; 96.0%) vs. residents 320/325 (98.5%) yielded no significant differences (pâ¯= 0.08). CONCLUSION: In clinical acute and emergency medicine, a standardized approach utilizing video laryngoscopy and a bougie following a structured training concept, can achieve an above-average high primary success rate with simultaneous low severe complications in the high-risk collective of critically ill emergency patients in an intrahospital setting.

INTRODUCTION: Between 2011 and 2014, The Combat Casualty Training Consortium research study sought to evaluate all aspects of combat casualty care, including mortality, with a special focus on the incidence and causes of potentially preventable deaths among U.S. combat fatalities. This study identified a major training gap in critical airway management. To address this gap, the Advanced Joint Airway Management System (AJAMS) was designed and assessed for physical fidelity and educational utility in a population of paramedic instructors. MATERIALS AND METHODS: Paramedic instructors served as participants in this prospective observational pilot study (n = 12). Participants interacted with three airway management trainers: The AJAMS trainer, the Laerdal Airway Management Trainer, and the TruCorp AirSim Advance Bronchi X Trainer. Participants then completed an evaluation of the trainer using a purpose-built data collection instrument that queried the trainer's realism and educational utility. Within-group differences were analyzed via a 1-way repeated measures ANOVA, with a Bonferroni post hoc analysis. Rank data were analyzed via non-parametric Freidman's test, and Wilcoxon signed-rank test post hoc analysis, corrected using the Bonferroni correction. RESULTS: The AJAMS trainer conveys significantly more physical fidelity (visual: P < .001, ηp2 = 0.977; tactile: P < .001, ηp2 = 0.983; and behavioral: P = .001, ηp2 = 0.971) and overall educational utility (χ2(2) = 15.273, P < .001) than the two commercially available skill trainers. CONCLUSIONS: These data suggest that physical fidelity is an important attribute in the design of simulators for health care, as perceived by expert instructors. These data illustrate that the AJAMS-integrated simulator demonstrates unparalleled physical fidelity, relative to commercially available airway management skill trainers.

Importance: Identifying longitudinal changes in advanced airway management by emergency medical services (EMS) is crucial for understanding practice patterns and optimizing care. Objective: To examine the longitudinal trends in endotracheal intubation (ETI) and supraglottic airway (SGA) utilization in a national EMS cohort. Design, Setting, and Participants: This retrospective cross-sectional study analyzed 2011 to 2022 data from the ESO Data Collaborative, a national database of US prehospital electronic health records. The study included all 911 EMS events in which advanced airway management was attempted. Data were analyzed from November 2022 to January 2024. Exposures: Advanced airway management attempts, including ETI, SGA, and surgical airways. Main Outcomes and Measures: The annual percentage of ETI and SGA attempts, stratified by underlying condition (cardiac arrest, nonarrest medical, nonarrest trauma, pediatrics). Results: Among 47.5 million EMS activations, 444â¯041 (mean [SD] age, 60.6 [19.8] years; 273â¯296 [61.5%] men) involved advanced airway management, including 305â¯584 (68.8%) that used ETI and 200â¯437 (45.1%) that used SGA. The overall incidence was 9.3 per 1000 EMS events. In the cardiac arrest cohort from 2011 to 2022, EMS events with ETI attempts decreased from 2470 of 2831 (87.3%) to 40â¯083 of 72â¯793 (55.1%) and those with SGA attempts increased from 711 of 2831 (25.1%) to 44â¯386 of 72â¯793 (61.0%). In the pediatric subset, there were similarly large decreases in ETI attempts, from 117 of 182 EMS events (97.3%) to 1573 of 2307 EMS events (68.2%), and increases in SGA attempts, from 11 of 182 EMS events (6.6%) to 1058 of 2307 EMS events (45.9%). In the nonarrest medical and nonarrest trauma cohorts, ETI attempts decreased and SGA attempts increased but to a much lower extent. Conclusions and Relevance: In this national cross-sectional study of EMS care episodes, there were marked shifts in advanced airway management practices, with the increased use of SGA and decreased use of ETI. These observations highlight current trends in EMS airway management practices.

Coffin-Lowry Syndrome (CLS) is a rare X-linked genetic disorder characterized by growth delays, facial dysmorphisms, and intellectual disabilities. Currently, there are limited published case reports regarding the anesthetic management of patients with CLS. Managing anesthesia for CLS patients can be complex due to difficult airway management. In this case report, we present a patient with CLS who underwent surgical intervention, highlighting the anesthetic considerations encountered throughout the perioperative period. We aim to summarize the difficulties involved in anesthetic management of rare conditions like CLS to improve clinical outcomes for affected individuals.
