Project description:IntroductionSignificant concerns raise for the healthcare workers involved in airway management of patients diagnosed with coronavirus 2019 disease (COVID-19). Due to shortages of personal protective equipment (PPE), barrier enclosure systems such as aerosol box (AB) have been proposed worldwide. The aim of this study was to evaluate our experience using AB as protective equipment in patients with COVID-19 in a third-level center in Mexico.MethodsA retrospective study of COVID-19 patients requiring airway management using an AB in the Hospital Central Sur de Alta Especialidad de Pemex in Mexico City from March 1 to June 1, 2020. Antropometric data, pre-intubation vital signs, and laboratory tests were recorded; the primary endpoints were intubation success rate and complications associated with AB and patients' mortality. As a secondary endpoint, AB subjective evaluation was explored by administering a survey after airway management procedures.ResultsThirty-nine patients for a total of 40 intubations were documented. Thirty-one (77.5%) were men, with a mean age of 61.65 years; successful intubation occurred in 39 (97.55%) of the procedures, and AB was used in 36 (90%) of intubations, with success in 28 (70.0%); A Cormack-Lehane grade 3 view was recorded in 18 patients (46.2%), and during the procedure, the AB had to be removed in 8 (22.2%) cases, with migration documented in 91.6% of cases. The 30-day mortality was 48.71%, with 23.0% of patients discharged. 83.3% of surveyed anesthesiologists reported significant limitations in manipulating airway devices with AB used.ConclusionOur data indicate that in clinical practice, the use of AB may hinder airway management and decrease the intubation success rate and may also result in patients' injury. Further studies are necessary to validate the use of AB in clinical practice, and they should not replace certified PPE.

Project description:Objectives:To determine the feasibility of integrating pre-intubation ultrasound into airway course and assess emergency medicine (EM) residents' confidence and comfort level in using ultrasound for pre-intubation hemodynamic stabilization and identifying cricothyroid membrane after the training session. Materials and methods:This is a retrospective study. Pre-intubation ultrasound training was delivered with the following ultrasound components (didactics and hands-on sessions using human models) to EM residents: (1) sonoanatomy and scanning technique to identify cricothyroid membrane and (2) pre-intubation echocardiography for recognition of acute right ventricular failure and pre-intubation hemodynamic stabilization. Results:A total of 56 EM residents participated in this study. Only 21% [95% confidence interval (CI), 10-31%] reported using ultrasound for pre-intubation hemodynamic stabilization. After the training session, 89% (95% CI, 81-97%) reported that ultrasound-based teaching increased their knowledge of pre-intubation hemodynamic stabilization compared with traditional teaching methods. On a scale of 1 (low) through 10 (high), the average comfort level for integrating ultrasound findings into medical decision making for pre-intubation hemodynamic stabilization was 6.8 (95% CI, 6.3-7.3). Seventy-nine percent (95% CI, 68-89%) reported that focused training in airway ultrasound is adequate to identify cricothyroid membrane. On a scale of 1 (low) through 10 (high), the average confidence level for identifying cricothyroid membrane using ultrasound was 6.6 (95% CI, 6.1-7.1). Conclusion:At our institution, we successfully integrated pre-intubation ultrasound into an airway course. Emergency medicine residents had a moderate level of comfort and confidence level using ultrasound for pre-intubation hemodynamic stabilization and identifying cricothyroid membrane after the training session.

Project description:Endotracheal intubation success rates in the prehospital setting are variable. Our objective was to describe the challenges encountered and corrective actions taken during the process of endotracheal intubation by paramedics.Analysis of prehospital airway management using a prospective registry that was linked to an emergency medical services administrative database.Emergency medical services system serving King County, Washington, 2006-2011. Paramedics in this system have the capability to administer neuromuscular blocking agents to facilitate intubation (i.e., rapid sequence intubation).A total of 7,523 patients more than 12 years old in whom paramedics attempted prehospital endotracheal intubation.None.An intubation attempt was defined as the introduction of the laryngoscope into the patient's mouth, and the attempt concluded when the laryngoscope was removed from the mouth. Endotracheal intubation was successful on the first attempt in 77% and ultimately successful in 99% of patients (7,433 of 7,523). Paramedics used a rapid sequence intubation strategy on 54% of first attempts. Among the subset with a failed first attempt (n = 1,715), bodily fluids obstructing the laryngeal view (50%), obesity (28%), patient positioning (17%), and facial or spinal trauma (6%) were identified as challenges to intubation. A variety of adjustments were made to achieve intubation success, including upper airway suctioning (used in 43% of attempts resulting in success), patient repositioning (38%), rescue bougie use (19%), operator change (16%), and rescue rapid sequence intubation (6%). Surgical cricothyrotomy (0.4%, n = 27) and bag-valve-mask ventilation (0.8%, n = 60) were rarely performed by paramedics as final rescue airway strategies.Airway management in the prehospital setting has substantial challenges. Success can require a collection of adjustments that involve equipment, personnel, and medication often in a simultaneous fashion.

Project description:Study objectiveThroughout the coronavirus disease 2019 pandemic, many emergency departments have been using passive protective enclosures ("intubation boxes") during intubation. The effectiveness of these enclosures remains uncertain. We sought to quantify their ability to contain aerosols using industry standard test protocols.MethodsWe tested a commercially available passive protective enclosure representing the most common design and compared this with a modified enclosure that incorporated a vacuum system for active air filtration during simulated intubations and negative-pressure isolation. We evaluated the enclosures by using the same 3 tests air filtration experts use to certify class I biosafety cabinets: visual smoke pattern analysis using neutrally buoyant smoke, aerosol leak testing using a test aerosol that mimics the size of virus-containing particulates, and air velocity measurements.ResultsQualitative evaluation revealed smoke escaping from all passive enclosure openings. Aerosol leak testing demonstrated elevated particle concentrations outside the enclosure during simulated intubations. In contrast, vacuum-filter-equipped enclosures fully contained the visible smoke and test aerosol to standards consistent with class I biosafety cabinet certification.ConclusionPassive enclosures for intubation failed to contain aerosols, but the addition of a vacuum and active air filtration reduced aerosol spread during simulated intubation and patient isolation.

Project description:IntroductionWhile awake tracheal intubation (ATI) is regarded as the gold standard for difficult airway management according to current guidelines, there seems to be a reluctance in its application. This retrospective cohort study, conducted at a German tertiary hospital over a 2-year period, aimed to demonstrate that integrating awake tracheal intubation using flexible bronchoscopy (ATI:FB) into routine airway management makes it a successful and safe approach.Materials and methodsIn 2019 and 2020, records from the data acquisition system (DAQ) and archived anesthesia records were screened to evaluate the specifics of ATI:FB procedures, focusing on overall success and safety. Analysis included complications, time required for ATI:FB, and potential influencing factors such as patient characteristics, indication, medical/operative specialty, sedation technique, route and experience of anesthesiologist. Logistic regression assessed the impact of various variables on occurrence of complications and linear regression, with log(time) as the dependent variable, evaluated median time required to perform ATI:FB.ResultsATI:FB constituted 4.3 % (n = 1,911) of all airway management procedures, predominantly observed in dental, oral, and maxillofacial surgery (46.5 %) and otorhinolaryngology (38.4 %). The success rate for ATI:FB was notably high at 99.6 %, with only 5.4 % of cases experiencing complications, including technical issues, agitation, and visibility obstruction due to mucous secretion. Complication risk was influenced by the medical specialty and the experience of the anesthesiologist. A strong effect was observed in otorhinolaryngology (OR = 4.54, 95 % CI [1.64; 14.06]). The median time required for ATI:FB was 16 minutes (IQR: 11 to 23), with factors such as indication (p < 0.0001), experience of anesthesiologist (p < 0.0001), sedation technique (p = 0.0408), priority of the procedure (p = 0.0134), and medical/operative specialty (p < 0.0001) affecting the duration. The median time required for ATI:FB differed significantly based on the experience of the anesthesiologist (p < 0.0001).ConclusionATI:FB proves successful and safe, with low complications and manageable procedural time. Experience of the anesthesiologist is a modifiable factor enhancing safety, emphasizing the need for ATI:FB integration into routine airway management.

Project description:ObjectivesTo systematically appraise the quality of clinical practice guidelines (CPGs) regarding awake tracheal intubation (ATI) and to compare the consistency of common recommendations.DesignSystematic review, critical appraisal and narrative synthesis of CPG recommendations for ATI.MethodsA systematic search of the PubMed, EMBASE, Cochrane, Web of Science, and Scopus databases was conducted up to July 1, 2024, to identify up-to-date CPGs. The AGREE II (Appraisal of Guidelines for Research and Evaluation) checklist was used to critically appraise the CPGs. Interrater agreement was determined via intraclass correlation coefficients (ICCs) with a two-way random effects model for each domain and overall rating score. All the suggestions extracted from the included guidelines were sorted and analyzed and summarized via the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system.ResultsOur study resulted in 939 records and ultimately 7 CPGs were appraised. The content of these CPGs covered six themes of ATI: indications, airway local anesthesia, the intubation procedure, checking the tube position, management after ATI failure, and the extubation process. When the AGREE II tool was used to appraise CPGs, only 3 CPGs were rated as "high" quality. With the exception of domain 1, we observed good agreement in all five other domains (ICCs over 0.7). These CPGs provided relatively consistent recommendations and evidence on intubation procedures and checking tube position. In terms of indications and airway local anesthesia, there was controversy. Twenty-nine recommendations regarding ATI were summarized through the GRADE system, among which 16 were considered relatively reliable.ConclusionThrough the AGREE II tool and the GRADE system, the strengths and weaknesses of each CPG were comprehensively analyzed on the basis of its scientific validity and practicability. Moreover, the limitations of the current CPGs in terms of indications, airway local anesthesia and complex clinical situations are presented, and clinicians are encouraged to apply the guidelines more scientifically and to update and improve the guidelines.Systematic review registrationCRD4202458548 (PROSPERO).

Project description:BackgroundThis study characterizes clinical and educational practices around the use of videolaryngoscopy in pediatric emergency airway management through qualitative exploration.MethodsThis is a descriptive qualitative study using semi-structured interviews of emergency medicine physicians. Physicians were selected by theoretical sampling from urban, tertiary care pediatric hospitals across the United States until theoretical data saturation was achieved. The study applied a constructivist grounded theory approach to data collection and analysis. Manual line-by-line coding of interview transcripts was used initially, then grouped into categories with constant comparative analysis to generate the final coding scheme organized by themes and subthemes. Finally, memo-writing and iterative analysis meetings explored relationships between themes and identified an interpretive model.ResultsTheoretical saturation was achieved after 10 of the initial 12 interviews. Emerging from the data were six themes that describe the concept of intubation sharing: (1) Videolaryngoscopy encompasses multiple modalities that all provide a shared view and ability to record; (2) Airway experts and systems help realize the full potential of videolaryngoscopy; (3) Videolaryngoscopy can be a clinical, educational, quality assurance and research tool; (4) Some skills required for videolaryngoscopy are unique, while others overlap with direct laryngoscopy; (5) Videolaryngoscopy allows a coaching laryngoscopist to provide real-time guidance to the primary laryngoscopist from a shared view; (6) Videolaryngoscopy provides an opportunity for post-intubation coaching and feedback and shared learning from a single experience for the provider community.ConclusionsThrough this multicenter qualitative interview study, we derived the concept of intubation sharing through videolaryngoscopy for real-time and remote coaching, for both the primary laryngoscopist and the community of emergency medicine providers who intubate.

Project description:Exposure of healthcare providers to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a significant safety concern during the coronavirus disease 2019 (COVID-19) pandemic, requiring contact/droplet/airborne precautions. Because of global shortages, limited availability of personal protective equipment (PPE) has motivated the development of barrier-enclosure systems, such as aerosol boxes, plastic drapes, and similar protective systems. We examined the available evidence and scientific publications about barrier-enclosure systems for airway management in suspected/confirmed COVID-19 patients. MEDLINE/Embase/Google Scholar databases (from December 1, 2019 to May 27, 2020) were searched for all articles on barrier enclosures for airway management in COVID-19, including references and websites. All sources were reviewed by a panel of experts using a Delphi method with a modified nominal group technique. Fifty-two articles were reviewed for their results and level of evidence regarding barrier device feasibility, advantages, protection against droplets and aerosols, effectiveness, safety, ergonomics, and cleaning/disposal. The majority of analysed papers were expert opinions, small case series, technical descriptions, small-sample simulation studies, and pre-print proofs. The use of barrier-enclosure devices adds to the complexity of airway procedures with potential adverse consequences, especially during airway emergencies. Concerns include limitations on the ability to perform airway interventions and the aid that can be delivered by an assistant, patient injuries, compromise of PPE integrity, lack of evidence for added protection of healthcare providers (including secondary aerosolisation upon barrier removal), and lack of cleaning standards. Enclosure barriers for airway management are no substitute for adequate PPE, and their use should be avoided until adequate validation studies can be reported.

Project description:IntroductionThis statement was planned on 11 March 2020 to provide clinical guidance and aid staff preparation for the coronavirus disease 2019 (COVID-19) pandemic in Australia and New Zealand. It has been widely endorsed by relevant specialty colleges and societies.Main recommendationsGeneric guidelines exist for the intubation of different patient groups, as do resources to facilitate airway rescue and transition to the "can't intubate, can't oxygenate" scenario. They should be followed where they do not contradict our specific recommendations for the COVID-19 patient group. Consideration should be given to using a checklist that has been specifically modified for the COVID-19 patient group. Early intubation should be considered to prevent the additional risk to staff of emergency intubation and to avoid prolonged use of high flow nasal oxygen or non-invasive ventilation. Significant institutional preparation is required to optimise staff and patient safety in preparing for the airway management of the COVID-19 patient group. The principles for airway management should be the same for all patients with COVID-19 (asymptomatic, mild or critically unwell). Safe, simple, familiar, reliable and robust practices should be adopted for all episodes of airway management for patients with COVID-19.Changes in management as a result of this statementAirway clinicians in Australia and New Zealand should now already be involved in regular intensive training for the airway management of the COVID-19 patient group. This training should focus on the principles of early intervention, meticulous planning, vigilant infection control, efficient processes, clear communication and standardised practice.
