Abstract Background Airway management in patients with out of hospital cardiac arrest (OHCA) is important and several methods are used. The establishment of a supraglottic airway device (SAD) is a common technique used during OHCA. Two types of SAD are routinely used in Norway; the Kings LTS-D™ and the I-gel®. The aim of this study was to compare the clinical performance of these two devices in terms of difficulty, number of attempts before successful insertion and overall success rate of insertion. Methods All adult patients with OHCA, in whom ambulance personnel used a SAD over a one-year period in the ambulance services of Central Norway, were included. After the event, a questionnaire was completed and the personnel responsible for the airway management were interviewed. Primary outcomes were number of attempts until successful insertion, by either same or different ambulance personnel, and the difficulty of insertion graded by easy, medium or hard. Secondary outcomes were reported complications with inserting the SAD’s. Results Two hundred and fifty patients were included, of whom 191 received I-gel and 59 received LTS-D. Overall success rate was significantly higher in I-gel (86%) compared to LTS-D (75%, p = 0.043). The rates of successful placements were higher when using I-gel compared to LTS-D, and there was a significant increased risk that the insertion of the LTS-D was unsuccessful compared to the I-gel (risk ratio 1.8, p = 0.04). I-gel was assessed to be easy to insert in 80% of the patients, as opposed to LTS-D which was easy to insert in 51% of the patients. Conclusions Overall success rate was significantly higher and the difficulty in insertion was significantly lower in the I-gel group compared to the LTS-D in patients with OHCA.

Abstract Background: Airway management in patients with out of hospital cardiac arrest (OHCA) is important and several methods are used. The establishment of a supraglottic airway device (SAD) is a common technique used during OHCA. Two types of SAD are routinely used in Norway; the Kings LTS-D™ and the I-gel®. The aim of this study was to compare the clinical performance of these two devices in terms of difficulty and number of attempts before successful insertion.Methods: All adult patients with OHCA, in whom ambulance personnel used a SAD over a one-year period in the ambulance services of Central Norway, were included. After the event, a questionnaire was completed and the personnel responsible for the airway management were interviewed. Primary outcomes were number of attempts until successful placement of SAD and graded difficulty of insertion. Secondary outcomes were specified challenges with the SAD at insertion. Intergroup differences were compared using Chi-square test for multiple groups.Results: Two hundred and fifty patients were included, of whom 191 received I-gel and 59 received LTS-D. Overall success rate was significantly higher in I-gel (86 %) compared to LTS-D (75%, p = 0,043). The difficulties of insertion were significantly lower among patients receiving I-gel (easy 80 %, medium 13 % and difficult 7 %) compared to LTS-D (easy 51 %, medium 22 % and difficult 27 %, p < 0,001). Conclusions: Overall success rate was significantly higher and the difficulty in insertion was significantly lower in the I-gel group compared to the LTS-D in patients with OHCA.

Objective: The study aimed to measure the success rate of pre-hospital tracheal intubation (TI) and supraglottic airway devices (SADs) performed by paramedics for adult patients and to assess the perception of paramedics of advanced airway management.Method: The study consisted of two phases: phase 1 was a retrospective analysis to assess the TI and SADs’ success rates when applied by paramedics for adult patients aged >14 years from 2012 to 2017, and phase 2 was a distributed questionnaire to assess paramedics’ perception of advanced airway management.Result: In phase 1, 24 patients met our inclusion criteria. Sixteen (67%) patients had TI, of whom five had failed TI but then were successfully managed using SADs. The TI success rate was 69% from the first two attempts compared to SADs (100% from first attempt). In phase 2, 63/90 (70%) paramedics responded to the questionnaire, of whom 60 (95%) completed it. Forty-eight (80%) paramedics classified themselves to be moderately or very competent with advanced airway management. However, most of them (80%) performed only 1‐5 TIs or SADs a year.Conclusion: Hospital-based paramedics (i.e. paramedics who are working at hospitals and not in the ambulance service, and who mostly respond to small restricted areas in Saudi Arabia) handled few patients requiring advanced airway management and had a higher competency level with SADs than with TI. The study findings could be impacted by the low sample size. Future research is needed on the success rate and impact on outcomes of using pre-hospital advanced airway management, and on the challenges of mechanical ventilation use during interfacility transfer.

Objective. To evaluate variation in airway management strategies in one suburban emergency medical services system treating patients experiencing out-of-hospital cardiac arrest (OHCA). Method. Retrospective chart review of all adult OHCA resuscitation during a 13-month period, specifically comparing airway management decisions. Results. Paramedics demonstrated considerable variation in their approaches to airway management. Approximately half of all OHCA patients received more than one airway management attempt (38/77 [49%]), and one-quarter underwent three or more attempts (25/77 [25%]). One-third of patients arrived at the emergency department with a different airway device than initially selected (25/77 [32%]). Conclusion. This study confirmed our hypothesis that paramedics’ selection of ventilation strategies in cardiac arrest varies considerably. This observation raises concern because airway management diverts time and energy from interventions known to improve outcomes in OHCA management, such as cardiopulmonary resuscitation and defibrillation. More research is needed to identify more focused airway management strategies for prehospital care providers.

Early insertion of a supraglottic airway (SGA) device could improve chest compression fraction by allowing providers to perform continuous chest compressions or by shortening the interruptions needed to deliver ventilations. SGA devices do not require the same expertise as endotracheal intubation. This study aimed to determine whether the immediate insertion of an i-gel® while providing continuous chest compressions with asynchronous ventilations could generate higher CCFs than the standard 30:2 approach using a face-mask in a simulation of out-of-hospital cardiac arrest. A multicentre, parallel, randomised, superiority, simulation study was carried out. The primary outcome was the difference in CCF during the first two minutes of resuscitation. Overall and per-cycle CCF quality of compressions and ventilations parameters were also compared. Among thirteen teams of two participants, the early insertion of an i-gel® resulted in higher CCFs during the first two minutes (89.0% vs. 83.6%, p = 0.001). Overall and per-cycle CCF were consistently higher in the i-gel® group, even after the 30:2 alternation had been resumed. In the i-gel® group, ventilation parameters were enhanced, but compressions were significantly shallower (4.6 cm vs. 5.2 cm, p = 0.007). This latter issue must be addressed before clinical trials can be considered.

Cardiac arrests are resulted by various aetiology including respiratory cause. Advanced airway placement is an important prehospital intervention for oxygenation and ventilation in respiratory cardiac arrest. We evaluated the association between of advanced airway method and neurologic outcome in arrest with respiratory cause. Adult witnessed non-traumatic OHCA (out-of-hospital cardiac arrest) treated by emergency medical service (EMS) providers in 2013–2017 were enrolled in a nationwide OHCA database. The association between airway management methods (endotracheal intubation (ETI), supraglottic airway (SGA) and bag valve mask (BVM)) and outcome were evaluated according to the presumed cause of cardiac arrest (cardiac, respiratory or others). The primary outcome was good neurological recovery at discharge. Multivariable logistic regression models with interaction analysis was conducted. Of 40,443 eligible OHCA patients, the cause of arrest of 90.0%, 7.5%, and 2.4% of patients were categorized as cardiac, respiratory and others, respectively. There were no statistically significant differences in the effect of the advanced airway type on good neurologic recovery in the total population (adjusted odds ratio (aOR) 0.96 (0.81–1.14) for ETI; 1.01 (95% confidence intervals (CI) 0.93–1.11) for BVM). However, ETI was associated with better neurologic recovery than SGA or BVM in OHCA in cardiac arrest with suspected respiratory cause (aOR 3.12 (95% CI 1.24–7.80) for ETI; 0.99 (95% CI 0.51–1.91) for BVM). Prehospital ETI was associated with good neurologic outcome when the cause of arrest was respiratory. ETI may be considered initially when a respiratory cause is suspected on the scene.

Introduction: Chest x-ray (CXR) abnormalities after cardiopulmonary resuscitation are common. Mechanisms by which these abnormalities develop are not fully elucidated, but aspiration of secretions and regurgitated gastric contents during prehospital airway management may be an important modifiable cause. Hypothesis: We hypothesized that endotracheal intubation (ETI) is associated with decreased incidence of CXR abnormalities after out-of-hospital cardiac arrest (OHCA), as compared to bag-valve-mask (BVM) or supraglottic airway (SGA) use. Methods: We conducted a retrospective review including resuscitated OHCA patients treated at a single academic medical center from 2010-2015. We included patients that had an initial CXR obtained within 66 hours of arrival. We excluded patients with tracheostomy, patients without positive pressure ventilation on emergency department (ED) arrival, or missing initial airway management data. We classified patients by airway management at the time of ED arrival into three groups: BVM, SGA, and ETI. Board certified thoracic imaging radiologists determined if there was any CXR abnormality, and if the observed abnormality was likely due to aspiration. The incidence of any abnormality and aspiration were compared between groups. A multivariable logistic regression model was used to adjust for baseline clinical characteristics. Results: Of the 766 subjects included in the study, 22 (3%) had BVM, 68 (9%) had SGA, and 676 (88%) had ETI. Most 58% were male, 34% had initial rhythm VF/VT, and 61% had a witnessed arrest. Any abnormality on CXR was identified in 543 (71%) cases, and likely aspiration was observed in 205 (27%) cases. Incidence of CXR abnormality was not significantly different between groups: BVM group 18/22 (82%), reference; SGA group 52/68 (76%), OR 0.75, 95% CI 0.13-4.31; ETI group 473/676 (70%), OR 0.81, 95% CI 0.16-4.01. Incidence of aspiration on CXR was also not different between groups: BVM group 6/22 (27%), reference; SGA group 19/68 (28%), OR 1.04, 95% CI 0.18-6.22; ETI group 180/676 (27%), OR 1.26, 95% CI 0.25-6.32. Conclusion: Prehospital airway management strategy for resuscitated OHCA patients was not associated with a significant difference in the incidence of any abnormality or aspiration on CXR.

IntroductionCurrent best practice for paramedic airway management of prehospital cardiac arrest is being continually reviewed following changes to the emphasis on intubation as a primary intervention within international resuscitation guidelines. Subsequently, there is increased enthusiasm for the use of next generation supraglottic airway devices. This review aimed to identify the current evidence for the safety and effectiveness of supraglottic airways for the management of prehospital cardiac arrest. MethodsA search of the electronic databases Medline, PubMed, Science Direct and Cochrane Library was conducted. Papers were excluded if they did not examine airway management in the prehospital cardiac arrest setting, involved the use of sedative or paralysing agents, involved paediatric patients, animals or cadavers. ResultsOf the 689 articles identified, 22 peer-reviewed articles were included for analysis. All 22 articles were from the following countries: America (3), America and Canada (1), Australia (2), Austria (1), Finland (1), Germany (4), Korea (1), Japan (4), The Netherlands (1), Norway (1), Taiwan (1), and United Kingdom (2). DiscussionThis review revealed large variances in both device effectiveness and patient outcome, particularly between geographical locations. Second-generation supraglottic airway devices demonstrated considerable improvement in effectiveness over their predecessors. Interestingly, the use of bag-valve mask ventilation reported better outcomes than any other form of advanced airway intervention. Studies also highlighted the diversity of airway management techniques and devices across global EMS systems. ConclusionDespite favourable indications of the effectiveness and safety of the next generation supraglottic airway devices, the paucity of prehospital-specific research (particularly randomised controlled trials) challenges decision making regarding prehospital airway management best practice.
