Abstract
Introduction : Les urgences vitales sont fréquentes dans les centres de santé isolés guyanais. La population médicale est composée de médecins généralistes avec peu de formation en médecine d’urgence.
Méthodes : Nous avons réalisé une étude descriptive au moyen d’un questionnaire diffusé à l’aide d’une mailing liste de 310 contacts de médecins ayant travaillé dans les centres délocalisés de prévention et de soins (CDPS) depuis les années 2010 à 2019.
Résultats : Nous avons obtenu 90 réponses sur 310 (29 %) et analysé 87 (28 %). La majorité des médecins était des généralistes (72 %) de moins de 40 ans (69 %) sans formation de médecine d’urgence (76 %). Les urgences majoritairement rencontrées étaient les comas et les polytraumatisés ainsi que les urgences gynéco-obstétricales. La majorité des médecins ont rapporté avoir été inconfortables durant ces prises en charge (67 %). La relation avec le service d’aide médicale urgente (Samu) a été jugée majoritairement adaptée (93 %). L’aide apportée par l’équipe paramédicale des CDPS était jugée correcte dans 49 % et excellente dans 48 % des cas. Plus d’un médecin sur cinq (21 %) a déclaré ne pas vouloir renouveler son contrat en CDPS du fait du vécu des urgences vitales. Afin d’améliorer la prise en charge des patients graves, les médecins sont favorables à la présence de fiches réflexes (87 %), à la formation en préaffectation sur mannequin (75 %), à de courtes formations aux déchoquages par des médecins urgentistes (67 %), à des alternatives à l’intubation orotrachéale telles que des dispositifs supraglottiques (68 %) et à l’aide guidée par la télémédecine (30 %).
Conclusion : Ce travail révèle une importante souffrance des médecins face aux difficultés vécues dans la prise en charge des urgences vitales. Afin de répondre aux problématiques soulevées par cette étude, la majorité des mesures d’amélioration évoquées dans ce travail sont en cours de mise en place depuis la fin de l’année 2019.

Prehospital Use of the Esophageal Tracheal Combitube Supraglottic Airway Device: A Retrospective Cohort Study. J Emerg Med 2022; 62:324-331. [PMID: 35067394 DOI: 10.1016/j.jemermed.2021.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 10/26/2021] [Accepted: 11/27/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND In the province of Quebec (Canada), paramedics use the esophageal tracheal Combitube (ETC) for prehospital airway management. OBJECTIVES Our main objective was to determine the proportion of patients with successful ventilation achieved after ETC use. Our secondary aim was to determine the number of ETC insertion attempts required to ventilate the patient. METHOD This is a retrospective cohort study. All patients who had ≥1 attempt to insert an ETC during prehospital care between January 1, 2017 and December 31, 2018 were included. Prehospital and in-hospital data were extracted. Successful ventilation was defined as thorax elevation, lung sounds on chest auscultation, or positive end-tidal capnography after ETC insertion. RESULTS A total of 580 emergency medical services interventions (99.3% cardiac arrests) were included. Most patients were men (62.5%) with a mean age 67.0 years (SD 17.6 years), and 35 (13.1%) of the 298 patients transported to emergency department survived to hospital discharge. Sufficient information to determine whether ventilation was successful or not was available for 515 interventions. Ventilation was achieved during 427 (82.7%) of these interventions. The number of ETC insertion attempts was available for 349 of the 427 successful ETC use. Overall, the first insertion resulted in successful ventilation during 294 interventions for an overall proportion of first-pass success ranging between 57.1% and 72.1%. CONCLUSION Proportions of successful ventilation and ETC first-pass success are lower than those reported in the literature with supraglottic airway devices. The reasons explaining these lower rates and their impact on patient-centered outcomes need to be studied.

Abstract
Background Prehospital emergency airway management challenges every paramedic. Emergencies evacuated from difficult areas by armed forces need airway maintenance throughout evacuation. Effective use of supraglottic airway (SGA) devices during prehospital transfer is life saving. This study compared use of four commonly available SGAs by Armed Forces paramedics in simulated emergency situations. Methods This prospective observational study conducted in a tertiary care institution, included 58 volunteer paramedics. They were trained on manikins before the study in basic airway skills and insertion of the four SGA devices under study viz. Classic laryngeal mask airway (cLMA), laryngeal tube (LT), I-gel, and Combitube. SGA device insertions were performed on 474 patients scheduled for short elective surgical procedures under general anesthesia. All volunteers inserted and assessed the four SGA devices equal number of times in different patients. Overall success rate, time for successful insertion, first attempt success rate, number of attempts for successful insertion, oro-pharyngeal leak pressures, ease of insertion, durability of device, and complications were recorded. Results Differences among the four groups were statistically significant in all parameters. Intergroup comparison revealed that both I-gel and LT were comparable to each other, however superior to cLMA and Combitube in all outcome measures except ease of insertion and durability of device where I-gel was better and oro-pharyngeal seal pressures where Combitube was better. Conclusion Considering all parameters, I-gel proved superior with minimal complications compared with other SGA devices tested. I-gel may be recommended for emergency airway rescue use in patients by military paramedics.

Abstract
INTRODUCTION Supraglottic airways, which are easily inserted and minimize interruptions in cardiopulmonary resuscitation manoeuvres, are now widely used in pre- and in-hospital emergencies. However, most studies in these devices do not specify whether they ensure good ventilation during CPR. This systematic review aims to determine whether there is evidence that supraglotic airways enable effective ventilation during resuscitation. METHODS The MEDLINE and COCHRANE databases were searched for studies published in English up to 30 November 2018. Eligible studies were all those that objectively evaluated tidal volume during resuscitation maneuvers in patients over 18 years of age using various supraglottic airways. RESULTS A total of 3734 articles were identified, of which 252 were duplicates. Only 1 objectively evaluated ventilation during resuscitation maneuvers and presented data relevant to this review. The study included 470 patients, 51 of which underwent spirometry. Only 4.48% of patients survived to hospital discharge; however, the correlation with ventilation effectiveness was not assessed. CONCLUSION There is no scientific evidence that supraglottic airways provide effective ventilation during resuscitation maneuvers. Evaluation by spirometry, chest impedance and ultrasound may help to determine the ventilatory efficacy of supraglottic airways during CPR, and clarify whether this factor contributes to the difficulties experienced in reversing cardiorespiratory arrest.

Abstract
BackgroundThe role of ambulance services has changed dramatically over the last few decades with the introduction of paramedics able to provide life-saving interventions, thanks to sophisticated equipment and treatments available. The number of 999 calls continues to increase, with adverse events theoretically possible with each one. Most patient safety research is based on hospital data, but little is known concerning patient safety when using ambulance services, when things can be very different. There is an urgent need to characterise the evidence base for patient safety in NHS ambulance services.ObjectiveTo identify and map available evidence relating to patient safety when using ambulance services.DesignMixed-methods design including systematic review and review of ambulance service documentation, with areas for future research prioritised using a Delphi process.Setting and participantsAmbulance services, their staff and service users in UK.Data sourcesA wide range of data sources were explored. Multiple databases, reference lists from key papers and citations, Google and the NHS Confederation website were searched, and experts contacted to ensure that new data were included in the review. The databases MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, Science Direct, Emerald, Education Resources Information Center (ERIC), Applied Social Sciences Index and Abstracts, Social Services Abstracts, Sociological Abstracts, International Bibliography of the Social Sciences (IBSS), PsycINFO, PsycARTICLES, Health Management Information Consortium (HMIC), NHS Evidence, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), NHS Economic Evaluation Database (NHS EED),Health Technology Assessment, the FADE library, Current Awareness Service for Health (CASH), OpenDOAR (Directory of Open Access Repositories) and Open System for Information on Grey Literature in Europe (OpenSIGLE) and Zetoc (The British Library's Electronic Table of Contents) were searched from 1 January 1980 to 12 October 2011. Publicly available documents and issues identified by National Patient Safety Agency (NPSA), NHS Litigation Authority (NHSLA) and coroners’ reports were considered. Opinions and perceptions of senior managers, ambulance staff and service users were solicited.Review methodsData were extracted from annual reports using two-stage thematic analysis, data from quality accounts were collated with safety priorities tabulated and considered using thematic analysis, NPSA incident report data were collated and displayed comparatively using descriptive statistics, claims reported to NHSLA were analysed to identify number and cost of claims from mistakes and/or poor service, and summaries of coroners’ reports were assessed using thematic analysis to identify underlying safety issues. The depth of analysis is limited by the remit of a scoping exercise and availability of data.ResultsWe identified studies exploring different aspects of safety, which were of variable quality and with little evidence to support activities currently undertaken by ambulance services. Adequately powered studies are required to address issues of patient safety in this service, and it appeared that national priorities were what determined safety activities, rather than patient need. There was inconsistency of information on attitudes and approaches to patient safety, exacerbated by a lack of common terminology.ConclusionPatient safety needs to become a more prominent consideration for ambulance services, rather than operational pressures, including targets and driving the service. Development of new models of working must include adequate training and monitoring of clinical risks. Providers and commissioners need a full understanding of the safety implications of introducing new models of care, particularly to a mobile workforce often isolated from colleagues, which requires a body of supportive evidence and an inherent critical evaluation culture. It is difficult to extrapolate findings of clinical studies undertaken in secondary care to ambulance service practice and current national guidelines often rely on consensus opinion regarding applicability to the pre-hospital environment. Areas requiring further work include the safety surrounding discharging patients, patient accidents, equipment and treatment, delays in transfer/admission to hospital, and treatment and diagnosis, with a clear need for increased reliability and training for improving handover to hospital.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

Abstract
Background: Emergency Medical Service (EMS) personnel manage the airway, but only a group of them are allowed to engage in Endotracheal Intubation (ETI). Our purpose was to evaluate if the use of laryngeal mask airway (LMA) or Combitube can be used by inexperienced care providers. Materials and Methods: A randomized, prospective manikin study was conducted. Fifty-nine participants were randomly assigned into two groups. Experienced group included 16 paramedics, eight anesthetic-technicians, and inexperienced group included 27 Emergency Medical Technician-Basic (EMT-B) and eight nurses. Our main outcomes were success rate and time to airway after only one attempt. Results: Airway success was 73% for ETI, 98.3% for LMA, and 100% for Combitube. LMA and Combitube were faster and had greater success than ETI (P = 0.0001). Inexperienced had no differences in time to securing LMA compared with experienced (6.05 vs. 5.4 seconds, respectively, P = 0.26). One failure in inexperienced, and no failure in experienced group occurred to secure the LMA (P = 0.59). The median time to Combitube placement in experienced and inexperienced was 5.05 vs. 5.00 seconds, P = 0.65, respectively. Inexperienced and experienced groups performed ETI in 19.15 and 17 seconds, respectively (P = 0.001). After the trial, 78% preferred Combitube, 15.3% LMA, and 6.8% ETI as the device of choice in prehospital setting. Conclusion: Time to airway was decreased and success rate increased significantly with the use of LMA and combitube compared with ETI, regardless of the experience level. This study suggests that both Combitube and LMA may be acceptable choices for management of airway in the prehospital setting for experienced and especially inexperienced EMS personnel.

Abstract
INTRODUCTION Endotracheal intubation (ETI) is currently considered superior to supraglottic airway devices (SGA) for survival and other outcomes among adults with non-traumatic out-of-hospital cardiac arrest (OHCA). We aimed to determine if the research supports this conclusion by conducting a systematic review. METHODS We searched the MEDLINE, Scopus and CINAHL databases for studies published between January 1, 1980, and 30 April 30, 2013, which compared pre-hospital use of ETI with SGA for outcomes of return of spontaneous circulation (ROSC); survival to hospital admission; survival to hospital discharge; and favorable neurological or functional status. We selected studies using pre-specified criteria. Included studies were independently screened for quality using the Newcastle-Ottawa scale. We did not pool results because of study variability. Study outcomes were extracted and results presented as summed odds ratios with 95% CI. RESULTS We identified five eligible studies: one quasi-randomized controlled trial and four cohort studies, involving 303,348 patients in total. Only three of the five studies reported a higher proportion of ROSC with ETI versus SGA with no difference reported in the remaining two. None found significant differences between ETI and SGA for survival to hospital admission or discharge. One study reported better functional status at discharge for ETI versus SGA. Two studies reported no significant difference for favorable neurological status between ETI and SGA. CONCLUSION Current evidence does not conclusively support the superiority of ETI over SGA for multiple outcomes among adults with OHCA.

Abstract
BACKGROUND In Dutch ambulance practice, failure or inability to intubate patients with altered oxygenation and/or ventilation leaves bag-valve mask ventilation as the only alternative, which is undesirable for patient outcome. A novel Laryngeal Mask Airway Supreme (LMA-S) device may be a suitable alternative. AIM To evaluate the effectiveness and suitability of the LMA-S for emergency medical services in daily out-of-hospital emergency practice. METHODS After a period of theoretical and practical training of ambulance paramedics in the use of the LMA-S, prospective data were collected on the utilisation of LMA-S in an observational study. Procedures for use were standardised and the evaluation included the number of direct intubation attempts before using LMA-S, attempts required, failure rate and the adequacy of ventilation. Data were analysed taking patient characteristics such as age and indication for ventilatory support into account. RESULTS The LMA-S was used 50 times over a period of 9 months (33 involving cardiorespiratory arrest, 14 primary and three rescue). The LMA-S could be applied successfully in all 50 cases (100%) and was successful in the first attempt in 49 patients (98%). Respiratory parameters showed adequate oxygenation. All paramedics were unanimously positive about the utilisation of LMA-S because of the easiness of the effort of insertion and general use, and emphasised its value as a useful resource for patients in need. CONCLUSIONS Ensuring ventilation support by using LMA-S by paramedics in prehospital emergency practice is safe and effective.

Abstract
INTRODUCTION Airway management is an important component of cardiopulmonary resuscitation (CPR). Recent guidelines recommend keeping any interruptions of chest compressions as short as possible and not lasting more than 10 seconds. Endotracheal intubation seems to be the ideal method for establishing a secure airway by experienced providers, but emergency medical technicians (EMT) often lack training and practice. For the EMTs supraglottic devices might serve as alternatives. METHODS 40 EMTs were trained in a 1-hour standardised audio-visual lesson to handle six different airway devices including endotracheal intubation, Combitube, EasyTube, I-Gel, Laryngeal Mask Airway and Laryngeal tube. EMTs performances were evaluated immediately after a brief practical demonstration, as well as after 1 and 3 months without any practice in between, in a randomised order. Hands-off time was pair-wise compared between airway devices using a repeated-measures mixed-effects model. RESULTS Overall mean hands-off time was significantly (p<0.01) lower for Laryngeal tube (6.1s; confidence interval 5.2-6.9s), Combitube (7.9s; 95% CI 6.9-9.0s), EasyTube (8.8s; CI 7.3-10.3s), LMA (10.2s; CI 8.6-11.7s), and I-Gel (11.9s; CI 10.2-13.7s) compared to endotracheal intubation (39.4s; CI 34.0-44.9s). Hands-off time was within the recommended limit of 10s for Combitube, EasyTube and Laryngeal tube after 1 month and for all supraglottic devices after 3 months without any training, but far beyond recommended limits in all three evaluations for endotracheal intubation. CONCLUSION Using supraglottic airway devices, EMTs achieved a hands-off time within the recommended time limit of 10s, even after three months without any training or practice. Supraglottic airway devices are recommended tools for EMTs with lack of experience in advanced airway management.

A comparison of the speed, success rate, and retention of rescue airway devices placed by first-responder emergency medical technicians: a high-fidelity human patient simulation study. J Emerg Med 2012; 44:784-9. [PMID: 22980415 DOI: 10.1016/j.jemermed.2012.07.045] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2011] [Revised: 01/09/2012] [Accepted: 07/01/2012] [Indexed: 11/17/2022]
Abstract
BACKGROUND Current airway management for most first-responder basic emergency medical technicians (EMT-Bs) does not include the use of blind-advanced-airway devices. OBJECTIVE To compare the speed, success rates, and skill retention with which EMT-Bs providers can place three blind-advanced-airway devices. METHODS Prospective study of 43 EMT-Bs trained in the use of the Esophageal-Tracheal-Combitube(®) (ETC), King LT(®) (KLT), and Laryngeal Mask Airway(™) (LMA). The time it took each participant to place each device correctly and ventilate a human patient simulator was assessed. Primary outcome measures were the success rate of proper insertion for each device and time interval from initiation of mouth insertion to initiation of chest rise. To assess skill retention, at 3 months the providers were reassessed under exact conditions. RESULTS At Day 1, time required to place an ETC, LMA, and KLT were 32.7 ± 12.3, 19.2 ± 6.2, and 20.1 ± 6.6 s, respectively. Using paired t-tests, LMA and KLT were faster than ETC, p < 0.0001. At 3 months, pair-wise comparisons showed the ETC took longer to place than the KLT and LMA, p < 0.0001; and the LMA took longer to place than the KLT, p = 0.0034 (36.4 ± 13.1 ETC, 24.8 ± 12.4 LMA, 19.0 ± 6.9 KLT). There was no statistical difference of failures in placing any device. CONCLUSIONS Comparison of three rescue airway devices placed by EMT-Bs providers showed that it takes significantly longer to place an ETC compared to an LMA and KLT both on Day 1 and 3 months later. Three-month retention studies revealed that it took significantly longer to place an LMA compared to the KLT.

Abstract
Emergency physicians, specialists, and primary care doctors across the health care delivery spectrum remain actively engaged in the provision of medical oversight for emergency medical services (EMS) systems, a vital link in the medical continuum of care. Practicing emergency physicians, regardless of their level of formal EMS training, interface with EMS system components and providers on a regular basis. It is important to remain aware of trends and practice patterns that have the potential to affect the care of emergency patients. PubMed was used to find articles for this review. The authors included EMS articles from 2010 felt applicable to all emergency physicians that fit the general topics discussed in this review. Some key articles from 2009 were also included. Case series were generally excluded. The selection is by no means an attempt to single out the best research articles. Like a single 12-lead electrocardiographic (ECG) tracing, this review represents a “snapshot” of current discussions in the EMS community. Prehospital medicine is a dynamic discipline, and its practice patterns are not identical to those found in a hospital emergency department (ED). The purpose of this literature review is to familiarize emergency physicians with some of the ongoing discussions in the prehospital literature.

Abstract
The best chance of survival with a good neurological outcome after cardiac arrest is afforded by early recognition and high-quality cardiopulmonary resuscitation (CPR), early defibrillation of ventricular fibrillation (VF), and subsequent care in a specialist center. Compression-only CPR should be used by responders who are unable or unwilling to perform mouth-to-mouth ventilations. After the first defibrillator shock, further rhythm checks and defibrillation attempts should be performed after 2 min of CPR. The underlying cause of cardiac arrest can be identified and treated during CPR. Drugs have a limited effect on long-term outcomes after cardiac arrest, although epinephrine improves the success of resuscitation, and amiodarone increases the success of defibrillation for refractory VF. Supraglottic airway devices are an alternative to tracheal intubation, which should be attempted only by skilled rescuers. Care after cardiac arrest includes controlled reoxygenation, therapeutic hypothermia for comatose survivors, percutaneous coronary intervention, circulatory support, and control of blood-glucose levels and seizures. Prognostication in comatose survivors of cardiac arrest needs a careful, multimodal approach using clinical and electrophysiological assessments after at least 72 h.

Abstract
OBJECTIVE To simplify airway management and minimize cardiopulmonary resuscitation (CPR) chest compression interruptions, some emergency medical services (EMS) practitioners utilize supraglottic airway (SGA) devices instead of endotracheal intubation (ETI) as the primary airway adjunct in out-of-hospital cardiac arrest (OHCA). We compared the outcomes of patients receiving ETI with those receiving SGA following OHCA. METHODS We performed a secondary analysis of data from the multicenter Resuscitation Outcomes Consortium (ROC) PRIMED trial. We studied adult non-traumatic OHCA receiving successful SGA insertion (King Laryngeal Tube, Combitube, and Laryngeal Mask Airway) or successful ETI. The primary outcome was survival to hospital discharge with satisfactory functional status (Modified Rankin Scale ≤3). Secondary outcomes included return of spontaneous circulation (ROSC), 24-h survival, major airway or pulmonary complications (pulmonary edema, internal thoracic or abdominal injuries, acute lung injury, sepsis, and pneumonia). Using multivariable logistic regression, we studied the association between out-of-hospital airway management method (ETI vs. SGA) and OHCA outcomes, adjusting for confounders. RESULTS Of 10,455 adult OHCA, 8487 (81.2%) received ETI and 1968 (18.8%) received SGA. Survival to hospital discharge with satisfactory functional status was: ETI 4.7%, SGA 3.9%. Compared with successful SGA, successful ETI was associated with increased survival to hospital discharge (adjusted OR 1.40; 95% CI: 1.04, 1.89), ROSC (adjusted OR 1.78; 95% CI: 1.54, 2.04) and 24-h survival (adjusted OR 1.74; 95% CI: 1.49, 2.04). ETI was not associated with secondary airway or pulmonary complications (adjusted OR 0.84; 95% CI: 0.61, 1.16). CONCLUSIONS In this secondary analysis of data from the multicenter ROC PRIMED trial, ETI was associated with improved outcomes over SGA insertion after OHCA.

Hands-off time during insertion of six airway devices during cardiopulmonary resuscitation: a randomised manikin trial. Resuscitation 2011; 82:1060-3.

Abstract
INTRODUCTION Cardiopulmonary resuscitation (CPR) guidelines recommend limiting interruptions of chest compressions because prolonged hands-off (i.e., non-compression) time compromises tissue perfusion. 2010 European Resuscitation Council guidelines suggest that chest compressions should be paused less than 10 s during airway device insertion. METHODS With approval of the local ethics committee of the Medical University of Vienna and written informed consent, we recruited 40 voluntary emergency medical technicians, none of whom had advanced airway management experience. After a standardised audio-visual lecture and practical demonstration, technicians performed airway management with each six airway devices (endotracheal tube, Combitube, EasyTube, laryngeal tube, Laryngeal Mask Airway, and I-Gel) during on-going chest compressions in a randomised sequence on a Resusci Anne Advanced Simulator. Data were analysed using a mixed-effects model accounting for the repeated measurements and pair-wise comparisons among the airway devices. RESULTS The hands-off time associated with airway management using an endotracheal tube (including all intubation attempts) was 48 s (95% confidence interval: 43-53). The hands-off time for airway management using a laryngeal tube was 8.4 (3.4-16.4) s, Combitube 10.0 (4.9-15.1) s, EasyTube 11.4 (6.4-16.4) s, LMA 13.3 (8.2-18.3) s and for I-Gel 15.9 (10.8-20.9) s. Hands-off time was significantly longer with the conventional endotracheal tube than with any of the other airway systems. Only a third of the technicians successfully inserted an endotracheal tube whereas all of them successfully positioned each supraglottic device. CONCLUSION Supraglottic devices appear to be a reasonable emergency airway management strategy, even for inexperienced personnel.

Abstract
INTRODUCTION Endotracheal intubation (ETI) is the most widespread method for emergency airway management. Several studies reported that ETI requires considerable skill and experience and if performed incorrectly, may result in serious adverse events. Unrecognized tube misplacement or oesophageal intubation is associated with high prehospital morbidity. This study investigates the usability of supraglottic airway devices compared to ETI and the skill retention of 41 previously inexperienced paramedics following training using a manikin model. METHODS 41 paramedics participated in this study. None had prior experience in airway management, apart from bag-valve ventilation. After a standardised audio-visual lecture lasting 45min, the paramedics participated in a practical demonstration using the advanced patient simulator SimMan(®) (Laerdal Medical, Stavanger, Norway). Afterwards, paramedics were instructed to perform airway-management using seven different techniques to secure the airway (ETI, Laryngeal mask unique [LMA], Proseal, Laryngeal tube disposable [LT-D(®)], I-Gel(®), Combitube(®), and EasyTube(®)) following a randomized sequence. Participants underwent reassessment after 3 months without any further training or practice in airway-management. RESULTS During the initial training session, ETI was successfully performed in 78% of cases, while 3 months later the success rate was 58%. For the supraglottic airway devices, five out of six were successfully used by all paramedics at both time points, the exception being Proseal(®). Our data show successful skill retention (success rate: 100%) after 3 months for five out of six supraglottic airway devices. Time to ventilation (T3) was significantly less for LMA, LT-D(®) and I-Gel(®) at all time points compared to ETI. CONCLUSION ETI performed by inexperienced paramedics is associated with a low success rate. In contrast, supraglottic airway devices like LMA, LT-D(®), I-Gel(®), Combitube(®) and EasyTube(®) are fast, safe and easy-to-use. Within the limitations of a manikin-study, this study suggests that inexperienced medical staff might benefit from using supraglottic airway devices for emergency airway management.

Abstract
BACKGROUND Airway management is a key component of prehospital care for seriously ill and injured patients. Oral endotracheal intubation (OETI) is the definitive airway of choice in most emergency medical services (EMS) systems. However, OETI may not be an approved skill for some clinicians or may prove problematic in certain patients because of anatomic abnormalities, trauma, or inadequate relaxation. In these situations alternative airways are frequently employed. However, the reported success rates for these devices vary widely, and established benchmarks are lacking. OBJECTIVE We sought to determine pooled estimates of the success rates of alternative airway devices (AADs) and needle cricothyrotomy (NCRIC) and surgical cricothyrotomy (SCRIC) placement through a meta-analysis of the literature. METHODS We performed a systematic literature search for all English-language articles reporting success rates for AADs, SCRIC, and NCRIC. Studies of field procedures performed by prehospital personnel from any nation were included. All titles were reviewed independently by two authors using prespecified inclusion criteria. Pooled estimates of success rates for each airway technique were calculated using a random-effects meta-analysis model. RESULTS Of 2,005 prehospital airway titles identified, 35 unique studies were retained for analysis of AAD success rates, encompassing a total of 10,172 prehospital patients. The success rates for SCRIC and NCRIC were analyzed across an additional 21 studies totaling 512 patients. The pooled estimates (and 95% confidence intervals [CIs]) for intervention success across all clinicians and patients were as follows: esophageal obturator airway-esophageal gastric tube airway (EOA-EGTA) 92.6% (90.1%-94.5%); pharyngeotracheal lumen airway (PTLA) 82.1% (74.0%-88.0%); esophageal-tracheal Combitube (ETC) 85.4% (77.3%-91.0%); laryngeal mask airway (LMA) 87.4% (79.0%-92.8%); King Laryngeal Tube airway (King LT) 96.5% (71.2%-99.7%); NCRIC 65.8% (42.3%-83.59%); and SCRIC 90.5% (84.8%-94.2%). CONCLUSIONS We provide pooled estimates for prehospital AAD, NCRIC, and SCRIC airway interventions. Of the AADs, the King LT demonstrated the highest insertion success rate (96.5%), although this estimate is based on limited data, and data regarding its ventilatory effectiveness are lacking; more data are available for the ETC and LMA. The ETC, LMA, and PTLA all had similar-but lower-success rates (82.1%-87.4%). NCRIC has a low rate of success (65.8%); SCRIC has a much higher success rate (90.5%) and should be considered the preferred percutaneous rescue airway.

Abstract
The goal of therapy for bradycardia or tachycardia is to rapidly identify and treat patients who are hemodynamically unstable or symptomatic due to the arrhythmia. Drugs or, when appropriate, pacing may be used to control unstable or symptomatic bradycardia. Cardioversion or drugs or both may be used to control unstable or symptomatic tachycardia. ACLS providers should closely monitor stable patients pending expert consultation and should be prepared to aggressively treat those with evidence of decompensation.

Abstract
OBJECTIVE To study utilization, indications, and outcomes associated with the use of a statewide, emergency medical services (EMS) standing-order protocol for cricothyrotomy. METHODS A statewide EMS database was queried for patients who received cricothyrotomy under a standardized, standing-order protocol. Patient EMS and hospital records were reviewed in a defined sequence with information recorded on a standardized collection form. RESULTS EMS records included eight years of practice with 1.5 million patient encounters. For each year studied, approximately 540 emergency medical technicians (EMTs) were certified to perform cricothyrotomy. State EMS providers performed a collective mean of eight cricothyrotomy procedures per year (range, 1-17), for a total of 68 cricothyrotomies performed within the eight-year period. Hospital records were available for review in 61 patients. Fifty-six patients received cricothyrotomy by open surgical incision, six by needle with jet ventilation, and one by both methods. Categorization of cricothyrotomy patients as trauma or medical was 61% trauma and 39% medical. Thirty-six patients (59%) were in cardiac arrest on EMS arrival and 12 patients (20%) died during transport. Thirteen trauma patients (21%) were admitted with eight patients surviving to discharge (13%). The neurologic impairment at time of hospital discharge was severe in four, moderate in two, and minimal or none in two patients (3%). CONCLUSION A considerable percentage of cricothyrotomy procedures were performed on patients with non-trauma-related diagnoses in this investigation describing a standing-order EMS protocol for cricothyrotomy. The majority of patients undergoing cricothyrotomy with this protocol were in cardiac arrest at the time of cricothyrotomy, with a small minority of patients surviving to hospital discharge and fewer surviving neurologically intact.

Abstract
OBJECTIVE Recent cardiac arrest resuscitation guidelines have recommended the esophageal tracheal Combitube (ETC) as an advanced airway management alternative for individuals who infrequently perform endotracheal intubation (ETI). This study attempted to analyze basic (nonparamedic) ambulance attendant success rates at ETI and ETC insertion as well as their continuing skill competency over time and whether ongoing practice on mannequins improved skill performance. METHODS Three hundred fifty-seven adult patients in cardiorespiratory arrest were treated by 81 basic ambulance attendants. Original study design called for the analysis of two treatment options in three patient groups: ETC insertion, ETI insertion with mannequin practice (ETI-MP), and ETI insertion without mannequin practice (ETI-NMP). The main outcome measures were:successful insertion and ventilation with ETC or ETI, assessed by receiving physicians; and differences in successful insertion/ventilation between the MP and NMP groups. RESULTS Successful insertion (intent-to-treat) for the ETI-NMP group was 70 of 111 (63%; 95% confidence interval [CI], 54-73%); ETI-MP success was 105 of 139 (76%; 95% CI, 67-84%); ETC-NMP success was 26 of 42 (62%; 95% CI, 49-75%); and ETC-MP success was 36 of 53 (68%; 95% CI, 54-82%). Continuing mannequin practice appeared to improve ETI success (as-treated): MP 75% versus NMP 61% (odds ratio, 2.1; 95% CI, 1.11-3.94). CONCLUSIONS There were similar rates of successful insertion/ventilation with the ETC and ETI. ETI insertion success was lower without mannequin practice. ETI skill erosion was partially mitigated by additional field experience.

Abstract
BACKGROUND The EasyTube (EzT) is a new sterile, disposable airway device approved by the European Union in February 2003 and by the U.S. Food and Drug Administration in January 2005. The two-lumen design of the EzT enables it to be used as an endotracheal tube or as a supraglottic emergency airway. OBJECTIVE To report the preliminary experiences with the EzT airway device in prehospital and in-hospital emergency airway management procedures. METHODS All airway management procedures involving the EzT were recorded for a period of 18 months. RESULTS The EzT was successfully used to intubate 15 patients with unanticipated airway difficulties during either anesthesia induction or prehospital airway management. In all patients, the EzT was positioned successfully in the first attempt, within a median time of 31 seconds until start of ventilation. Effective supraglottic ventilation and oxygenation was achieved within 25 to 40 seconds. In three patients, the EzT needed one additional repositioning maneuver. On removal of the EzT, no blood was observed on the surface of the device, as a sign of absence of potential mucosal lesion. No injuries were observed in the mouth, pharynx, or esophagus. CONCLUSIONS The first experiences with the use of the EzT are promising. In emergency airway management procedures presenting problems, the device successfully established sufficient ventilation and oxygenation. Further studies are needed to compare its value with those of other supraglottic devices.

Abstract
This article is intended as a generic guide to evidence-based airway management for all categories of pre-hospital personnel. It is based on a review of relevant literature but the majority of the studies have not been performed under realistic, pre-hospital conditions and the recommendations are therefore based on a low level of evidence (D). The advice given depends on the qualifications of the personnel available in a given emergency medical service (EMS). Anaesthetic training and routine in anaesthesia and neuromuscular blockade is necessary for the use of most techniques in the treatment of patients with airway reflexes. For anaesthesiologists, the Task Force commissioned by the Scandinavian Society of Anaesthesia and Intensive Care Medicine recommends endotracheal intubation (ETI) following rapid sequence induction when securing the pre-hospital airway, although repeated unsuccessful intubation attempts should be avoided independent of formal qualifications. Other physicians, as well as paramedics and other EMS personnel, are recommended the lateral trauma recovery position as a basic intervention combined with assisted mask-ventilation in trauma patients. When performing advanced cardiopulmonary resuscitation, we recommend that non-anaesthesiologists primarily use a supraglottic airway device. A supraglottic device such as the laryngeal tube or the intubation laryngeal mask should also be available as a backup device for anaesthesiologists in failed ETI.

Abstract
This manuscript reviews the latest literature on alternative airways for use in children requiring prehospital airway management. Case discussions serve as a springboard for discussion of alternatives to bag-mask ventilation and endotracheal intubation for management of ventilation in infants and children in the prehospital setting. Few airway procedures have been studied with any rigor in this setting, and most of the data that are available are extrapolated from adults. Laryngeal mask airway may be the best alternative airway with the most promise to add to the armamentarium of the prehospital provider, but no controlled trial to date has been conducted.

Abstract
PURPOSE The Esophageal-Tracheal Combitube (Combitube) is widely used for the management of the airway during cardiopulmonary resuscitation in the pre-hospital setting. Although serious complications have been reported with the Combitube, there is a paucity of data relative to the frequency and nature of such complications. The objective of this retrospective study was to determine the incidence and the nature of complications associated to the Combitube in the pre-hospital setting. METHODS Since 1993, in the Quebec City Health Region, the basic life support treatment algorithm for emergency medical technicians has included the use of a Combitube as the primary airway device for management of all patients presenting with cardiac or respiratory arrest. The database of the emergency coordination services was searched for the period between 1993 and 2003 (2,981 patients). Only those patients who survived at least 12 hr were included. Medical records of these patients were reviewed to identify complications related to the use of the Combitube. RESULTS Two-hundred-eighty (280) patients were identified. Fifty-eight (58) patients (20.7%, confidence interval (CI)95%=16.0%-25.4%) presented 69 complications: aspiration pneumonitis (n=31), pulmonary aspiration (n=16), pneumothorax (n=6), upper airway bleeding (n=4), esophageal laceration (n=3), sc emphysema (n=2), esophageal perforation and mediastinitis (n=2), tongue edema (n=2), vocal cord injury (n=1), tracheal injury (n=1), and pneumomediastinum (n=1). Thirteen of these complications (12 patients, 4.3%, CI95%=2.0%-6.3%) were judged as most likely resulting from trauma associated with insertion of the Combitube. CONCLUSION The use of the Combitube in the pre-hospital setting is associated with a notable incidence of serious complications.

Abstract
The new CPR guidelines are based on a scientific consensus which was reached by 281 international experts. Chest compressions (100/min, 4-5 cm deep) should be performed in a ratio of 30:2 with ventilation (tidal volume 500 ml, Ti 1 s, FIO2 if possible 1.0). After a single defibrillation attempt (initially biphasic 150-200 J, monophasic 360 J, subsequently with the respective highest energy), chest compressions are initiated again immediately for 2 min. Endotracheal intubation is the gold standard; other airway devices may be employed as well depending on individual skills. Drug administration routes for adults and children: first choice IV, second choice intraosseous, third choice endobronchial [epinephrine dose 2-3x (adults) or 10x (pediatric patients) higher than IV]. Vasopressors: 1 mg epinephrine every 3-5 min IV. After the third unsuccessful defibrillation attempt amiodarone IV (300 mg); repetition (150 mg) possible. Sodium bicarbonate (1 ml/kg 8.4%) only in excessive hyperkalemia, metabolic acidosis, or intoxication with tricyclic antidepressants. Consider atropine (3 mg) and aminophylline (5 mg/kg). Thrombolysis during spontaneous circulation only in myocardial infarction or massive pulmonary embolism; during CPR only during massive pulmonary embolism. Cardiopulmonary bypass only after cardiac surgery, hypothermia or intoxication. Pediatrics: best improvement in outcome by preventing cardiocirculatory collapse. Alternate chest thumps and chest compression (infants), or abdominal compressions (>1-year-old) in foreign body airway obstruction. Initially five breaths, followed by chest compressions (100/min; approximately 1/3 of chest diameter): ventilation ratio 15:2. Treatment of potentially reversible causes (4 "Hs", "HITS": hypoxia, hypovolemia, hypo- and hyperkaliemia, hypothermia, cardiac tamponade, intoxication, thrombo-embolism, tension pneumothorax). Epinephrine 10 microg/kg IV or intraosseously, or 100 microg (endobronchially) every 3-5 min. Defibrillation (4 J/kg; monophasic oder biphasic) followed by 2 min CPR, then ECG and pulse check. Newborns: inflate the lungs with bag-valve mask ventilation. If heart rate<60/min chest compressions:ventilation ratio 3:1 (120 chest compressions/min). Postresuscitation phase: initiate mild hypothermia [32-34 degrees C for 12-24 h; slow rewarming (<0.5 degrees C/h)]. Prediction of CPR outcome is not possible at the scene; determining neurological outcome within 72 h after cardiac arrest with evoked potentials, biochemical tests and physical examination. Even during low suspicion for an acute coronary syndrome, record a prehospital 12-lead ECG. In parallel to pain therapy, aspirin (160-325 mg PO or IV) and in addition clopidogrel (300 mg PO). As antithrombin, heparin (60 IU/kg, max. 4000 IU) or enoxaparine. In ST-segment elevation myocardial infarction, define reperfusion strategy depending on duration of symptoms until PCI (prevent delay>90 min until PCI). Stroke is an emergency and needs to be treated in a stroke unit. A CT scan is the most important evaluation, MRT may replace a CT scan. After hemorrhage exclusion, thrombolysis within 3 h of symptom onset (0.9 mg/kg rt-PA IV; max 90 mg within 60 min, 10% of the entire dosage as initial bolus, no aspirin, no heparin within the first 24 h). In severe hemorrhagic shock, definite control of bleeding is the most important goal. For successful CPR of trauma patients, a minimal intravascular volume status and management of hypoxia are essential. Aggressive fluid resuscitation, hyperventilation, and excessive ventilation pressure may impair outcome in severe hemorrhagic shock. Despite bad prognosis, CPR in trauma patients may be successful in select cases. Any CPR training is better than nothing; simplification of contents and processes remains important.

Abstract
When conventional intubation methods fail, an accessory rescue airway device must be immediately available and rapidly deployed to assist the clinician in managing the airway. I reviewed an emergency intubation database to determine what airway devices were used as a backup to rescue the primary rescue device failures. The bougie and the laryngeal mask airway each have an intrinsic failure rate. The Combitube(R), commonly used in the emergency prehospital setting, appeared to be a useful secondary rescue device in the hospital setting when the bougie and laryngeal mask airway failed.

Abstract
INTRODUCTION The EasyTube, which is constructed in a similar way to the Combitube, is a recently introduced alternative to tracheal intubation for airway management in emergency medicine. OBJECTIVE To determine if there is a difference in rate of, and time to, successful airway placement and ventilation using tracheal intubation, Combitube and EasyTube. METHODS Twenty-six paramedics, trained in tracheal intubation received additional training in the use of the Combitube and the EasyTube. Each participant performed all three methods twice in random order on a manikin. Time to successful ventilation (presented as mean and standard deviation) and success rate were recorded. RESULTS Mean time to successful ventilation was significantly longer for tracheal intubation (45.2 s (S.D.=15.8)) than for the Combitube (36.0 s (S.D. = 8.6)) p = 0.002 and the EasyTube (38.0 s (S.D.=15.3)) p = 0.023 with no difference between the latter (p = 1.000). Success rate for the Combitube and EasyTube combined (103/104) was significantly higher than for tracheal intubation (45/52) with odds ratio 16.0 (95% CI: 1.9-134); p = 0.002. CONCLUSION For paramedics tested on manikins placement success rate was higher with less time required for the Combitube and Easytube than for tracheal intubation with no differences between the Combitube and EasyTube.

Abstract
While remaining prominent in paramedic care and beneficial to some patients, out-of-hospital endotracheal intubation has not clearly improved survival or reduced morbidity from critical illness or injury when studied more broadly. Recent studies identify equivocal or unfavorable clinical effects, adverse events and errors, interaction with other important resuscitation interventions, and challenges in providing and maintaining procedural skill. We provide an overview of current data evaluating the overall effectiveness, safety, and feasibility of paramedic out-of-hospital endotracheal intubation. These studies highlight our limited understanding of out-of-hospital endotracheal intubation and the need for new strategies to improve airway support in the out-of-hospital setting.

Abstract
OBJECTIVE To determine the change in number of endotracheal intubations per paramedic after the implementation of Combitube use and to explore consequences. METHODS Before-and-after study; urban/suburban EMS system; population 1 million. Number of patients 16 years and older, type of airway used, attempts, and successes were abstracted for time periods before and after the use of Combitubes. The number of endotracheal intubations/paramedic for each period was calculated. RESULTS Three-year pre-Combitube: patients 50983; 6.6% arrests; 3142 received an endotracheal intubation attempt with 93.5% success. The average annual number of paramedics was 153 with 6.9 +/- 6.4 intubations per paramedic per year. Three-year post-Combitube: patients 55959; 6.0% arrests; 2913 received an advanced airway attempt: 860 Combitubes, success 89.4%; 2144 endotracheal intubations, success 91.6% (95% confidence interval success rate difference, 0.5-3.3; P = .007). The average annual number of paramedics was 177 with 3.7 +/- 3.3 intubations per paramedic per year. CONCLUSION After implementation of the Combitube, the number of endotracheal intubation attempts/paramedic and success rates decreased.

Abstract
Airway management involves far more than just proficiency with tracheal intubation techniques. There are several infraglottic techniques available and the method chosen will depend on the accessibility of equipment, the level of training and expertise, and the patient's specific injury or disease. Endotracheal intubation is most commonly performed by direct laryngoscopy. Several modifications of laryngoscope blades and a variety of adjuncts such as bougies may help to accomplish even a difficult airway. Rigid intubation fibrescopes do improve the view of the larynx, especially in patients with difficult anatomy. They also permit tracheal intubation with less head and cervical spine movement than is often generated by direct laryngoscopy. Successful intubation, however, requires considerable experience, as in intubation techniques using flexible fibrescopes. Both the EasyTube and the Combitube serve as an infraglottic or a supraglottic airway. The tip of the EasyTube resembles the one of an endotracheal tube, whereas the Combitube is much more bulky.

Abstract
Securing and monitoring the airway are among the key requirements of appropriate therapy in emergency patients. Failures to secure the airways can drastically increase morbidity and mortality of patients within a very short time. Therefore, the entire range of measures needed to secure the airway in an emergency, without intermediate ventilation and oxygenation, is limited to 30-40 seconds. Endotracheal intubation is often called the 'gold standard' for airway management in an emergency, but multiple failed intubation attempts do not result in maintaining oxygenation; instead, they endanger the patient by prolonging hypoxia and causing additional trauma to the upper airways. Thus, knowledge and availability of alternative procedures are also essential in every emergency setting. Given the great variety of techniques available, it is important to establish a well-planned, methodical protocol within the framework of an algorithm. This not only facilitates the preparation of equipment and the training of personnel, it also ensures efficient decision-making under time pressure. Most anaesthesia-related deaths are due to hypoxaemia when difficulty in securing the airway is encountered, especially in obstetrics during induction of anaesthesia for caesarean delivery. The most commonly occurring adverse respiratory events are failure to intubate, failure to recognize oesophageal intubation, and failure to ventilate. Thus, it is essential that every anaesthesiologist working on the labour and delivery ward is comfortable with the algorithm for the management of failed intubation. The algorithm for emergency airway management describing the sequence of various procedures has to be adapted to internal standards and to techniques that are available.

Abstract
In out-of-hospital emergencies, including cardiac arrest, securing the airway and providing adequate lung ventilation are of paramount importance. Tracheal intubation is perceived as the gold standard technique and it is recommended by International Guidelines, but non skilled personnel often find the procedure difficult to achieve. Supraglottic devices are a good alternative in these situations, because they are superior to a bag-valve-mask for lung ventilation and offer better protection from aspiration. We have tested the laryngeal tube (LT) in out-of-hospital emergencies by minimally trained nurses. The LT was placed in 30 patients in cardiac arrest. LT insertion was successful within two attempts in 90% of patients, and ventilation was adequate in 80% of cases. No regurgitation occurred in any patient. The laryngeal tube remained in the correct position throughout resuscitation attempts in 93.3% of cases, while in two patients (6.6%) it became dislodged. In a subjective evaluation of the manoeuvre by nurses (ease of insertion, adequacy of ventilation, protection from aspiration), 86.7% of them expressed a positive opinion. The laryngeal tube appeared to be a reliable device for nurses to manage the airway in out-of-hospital emergencies.
