Swedish consensus regarding difficult pre-hospital airway management: a Delphi study

BackgroundThe aim of this study was to establish a consensus among experts in prehospital work regarding the management of difficult airways in prehospital care in Sweden. The results were subsequently used to develop an algorithm for handling difficult airway in prehospital care, as there was none available in Sweden prior to this study.MethodsThis two-round Delphi study was conducted by forming an expert panel comprising anesthesiologists and anesthesia nurses working in prehospital setting in Sweden. The expert panel responded digital forms with questions and statements related to airway management. The study continued until consensus was reached, defined as more than 70% agreement. The study took place from December 4, 2021, to May 15, 2022.ResultsIn the first round, 74 participants took part, while the second round involved 37 participants. Consensus was reached in 16 out of 17 statements. 92% of the participants agreed that an airway algorithm adapted for prehospital use is necessary.ConclusionsThe capacity to adapt the approach to airway management based on specific pre-hospital circumstances is crucial. It holds significance to establish a uniform framework that is applicable across various airway management scenarios. Consequently, the airway management algorithm that has been devised should be regarded as a recommendation, allowing for flexibility rather than being interpreted as a rigid course of action.This represents the inaugural nationwide algorithm for airway management designed exclusively for pre-hospital operations in Sweden. The algorithm is the result of a consensus reached by experts in pre-hospital care.

Advanced airway management in the prehospital setting during traumatic out-of-hospital cardiac arrest following traffic collision in Japan, 2013-2019

Abstract Funding Acknowledgements Type of funding sources: Private grant(s) and/or Sponsorship. Main funding source(s): Okinaka Memorial Institute for Medical Research; Toranomon Hospital. Background The European guideline on management of major bleeding and coagulopathy following trauma (sixth edition) recommend that endotracheal intubation or alternative airway management be performed without delay to facilitate adequate ventilation and oxygenation during trauma resuscitation. However, controversy remains as to whether advanced airway management should be provided for out-of-hospital cardiac arrest (OHCA) in the prehospital setting. Purpose This study aimed to examine the association of prehospital advanced airway management with outcomes after traumatic OHCA. Methods This observational study analyzed the Japanese government-led nationwide population-based registry data of OHCA patients. Patients with traumatic OHCA following traffic collision who received advanced life support in the prehospital setting from 2013 to 2019 were included. Propensity score matching was used to examine the association of advanced airway management with outcomes after traumatic OHCA following traffic collision. The primary outcome was one-month survival. Results A total of 5,617 patients (mean [SD] age, 60.1 [21.6] years; 68.6% male) were included. 3,822 (68.0%) received advanced airway management, and 1,795 (32.0%) did not. After adjusting for potential confounders using propensity score matching, advanced airway management was associated with decreased chance of one-month survival (23/1452 [1.6%] vs 43/1452 [3.0%]; RR, 0.53; 95%CI, 0.32-0.88; P=0.0128). Similar association was observed for prehospital return of spontaneous circulation (88/1452 [6.1%] vs 139/1452 [9.6%]; RR, 0.63; 95%CI, 0.49-0.82; P=0.0004). Conclusion Among patients with traumatic OHCA following traffic collision, advanced airway management was associated with decreased chance of one-month survival and prehospital return of spontaneous circulation.

A Simpler Method for Choosing Adult i-gel Size: An Evaluation of Real-World Prehospital Data

ObjectiveThe i-gel supraglottic airway device (Intersurgical, Berkshire, UK) is commonly used in the United States and worldwide for prehospital airway management. Previous research has suggested that a sex-based method of size selection (4.0 for female patients and 5.0 for male patients) is superior to a weight-based method in patients undergoing elective anesthesia. Our objective was to compare a sex-based i-gel size selection strategy with a weight-based strategy using real-world prehospital data. MethodsThe ESO Data Collaborative 2018 to 2022 dataset was used. All initial i-gel insertion attempts in patients > 18 years of age were evaluated for inclusion. Insertion attempts were excluded if age, sex, weight, success, or device size was not documented. Logistic regression was used to compare the rate of insertion failure on the first attempt for the group placed in alignment with the weight-based but not sex-based method with the group placed in alignment with the sex-based but not weight-based method. ResultsAfter the application of the exclusion criteria, 39,867 initial i-gel insertion attempts were included. The overall rate of failure was 6.5% (2,585/39,867). The rate of unsuccessful i-gel placement was similar when i-gel devices were placed in alignment with a sex-based size selection method in comparison to i-gel placement in alignment with a weight-based selection strategy (6.0% vs. 6.4%). Logistic regression analysis did not reveal a significant difference between groups (odds ratio: 1.08; 95% confidence interval: 0.95-1.23). ConclusionThe use of a sex-based method of i-gel size selection may be equivalent with respect to the rate of unsuccessful i-gel placement on the first attempt in comparison to a weight-based method.

Influence of Patient Weight on Prehospital Advanced Airway Procedure Success Rates

ABSTRACT Objective: Previous investigations of the relationship between obesity and difficult airway management have provided mixed results. Almost universally, these studies were conducted in the hospital setting, and the influence of patient body weight on successful prehospital airway management remains unclear. Because patient weight could be one readily identifiable risk factor for problematic airway interventions, we sought to evaluate this relationship. Methods: We conducted a retrospective analysis using the 2020 ESO Data Collaborative dataset. The inclusion criteria consisted of adult patients weighing >30kg with an attempted orotracheal intubation (OTI) and/or blind insertion airway device (BIAD) placement. Separate logistic regression models were developed to determine the influence of weight (dichotomized at 100kg) on cumulative procedure success for OTI and BIAD, and linear regression models were used to identify trends for each across weight strata. Results: A total of 45,344 patients met inclusionary criteria, among which 40,668(89.7%) suffered from a medical emergency, followed by 3,130(6.9%) with traumatic injuries, and 1,546(3.4%) attributable to a combined medical-trauma etiology. Cardiac arrest occurred either prior to EMS arrival or at some point during EMS care in 38,210(84.3%) patients. OTI was attempted in 18,153(40.0%) patients, while 21,597(47.6%) had a BIAD attempt and 5,594(12.3%) had both airway types attempted. The overall cumulative insertion success rates for OTI and BIAD were 79.5% and 92.7%, respectively. Altogether, 2,711(6.0%) had no advanced airway of any type successfully placed, which represents the overall failed advanced airway rate. After controlling for patient age, sex, minority status, and call type (medical vs. trauma), weight >100kg was associated with decreased likelihood of cumulative OTI success (OR = 0.64,p < 0.001), but higher likelihood of cumulative BIAD success (OR = 1.31,p < 0.001). Cumulative OTI success was associated with a negative 0.6% linear trend per 5kg of body weight (p < 0.001) while cumulative BIAD success had a 0.2% positive trend (p < 0.001). Conclusion: This retrospective analysis of a national EMS database revealed that increasing patient weight was negatively associated with intubation success. A positive, but smaller, linear trend was observed for BIAD placement. Patient weight may be an easily identifiable predictor of difficult oral intubation and may be a consideration when selecting an airway management strategy.

In-hospital mortality after prehospital endotracheal intubation versus alternative methods of airway management in trauma patients. A cohort study from the TraumaRegister DGU®.

Prehospital airway management in trauma is a key component of care and is associated with particular risks. Endotracheal intubation (ETI) is the gold standard, while extraglottic airway devices (EGAs) are recommended alternatives. There is limited evidence comparing their effectiveness. In this retrospective analysis from the TraumaRegister DGU®, we compared ETI with EGA in prehospital airway management regarding in-hospital mortality in patients with trauma. We included cases only from German hospitals with a minimum Abbreviated Injury Scale score ≥ 2 and age ≥ 16 years. All patients without prehospital airway protection were excluded. We performed a multivariate logistic regression to adjust with the outcome measure of hospital mortality. We included n = 10,408 cases of whom 92.5% received ETI and 7.5% EGA. The mean injury severity score was higher in the ETI group (28.8 ± 14.2) than in the EGA group (26.3 ± 14.2), and in-hospital mortality was comparable: ETI 33.0%; EGA 30.7% (27.5 to 33.9). After conducting logistic regression, the odds ratio for mortality in the ETI group was 1.091 (0.87 to 1.37). The standardized mortality ratio was 1.04 (1.01 to 1.07) in the ETI group and 1.1 (1.02 to 1.26) in the EGA group. There was no significant difference in mortality rates between the use of ETI or EGA, or the ratio of expected versus observed mortality when using ETI.

The current trend of emergency airway management: a clinical review.

Airway management is a fundamental and intricate process that involves a sequence of integrated tasks. Situations requiring emergency airway management may occur in emergency department, intensive care units, and various other spaces. Emergency airway management can face a variety of challenges during preparation, intubation, and post-intubation, and may result in significant complications for the patients. Therefore, many countries are establishing step-by-step systemization and detailed guidelines, and updating the content based on the latest research. This clinical review introduces the current trends in emergency airway management, such as emergency airway management algorithms, comparison of video and direct laryngoscopy, rapid sequence intubation, pediatric airway management, pre-hospital airway management, surgical airway management, and airway management education.

Prehospital Cervical Spine (C-spine) Stabilization and Airway Management in a Trauma Patient: A Review.

Severe traumatic damage to the brain-to-body signaling bundle that results in bruising and a partial or total tear of the spinal cord is known as a spinal cord injury (SCI). SCI may develop at the time of an eventor after. It can also developwhile handling the patient andcan worsen during the transportation of the patient. So prehospital care is crucial to prevent or minimize SCI. Prehospital care involves examining the patient, immobilizing the cervical spine (C-spine), providing cardiovascular support (keeping the mean arterial blood pressure over 85 mmHg), and carefully managing the airway (possibly intubating the patient using manual in-line stabilization (MILS)).Methylprednisolone (MPS) and other pharmacological treatments have not been shown to offer clinically meaningful and essential benefits for people with SCI. The therapeutic use of MPS in patients with SCI in the prehospital context is no longer supported. Additionally, whether or not pharmaceutical drugs will be effective in therapeutic hypothermiais unknown. When performing endotracheal intubation on these patients, the potential for C-spine damage is always considered. During intubation, the MILSapproach significantly reduces C-spine movement. The MILS method, however, can potentially restrict mouth opening and result in subpar laryngoscopic vision. These issues can be handled using the recently developed video laryngoscope, such as Airtraq laryngoscope and AirWay Scope (AWS). Compared to a direct laryngoscope, the AWSand Airtraqlaryngoscope reduced the improvement of intubation conditions and the acceleration of tracheal intubation through the occiput-C1 and C2-C4 levels of the C-spineextension movement.

In Search of the Truth: Choice of Ground-Truth for Predictive Modeling of Trauma Team Activation in Pediatric Trauma.

Assigning trauma team activation levels for trauma patients is a classification task that machine learning models can help optimize. However, performance is dependent upon the "ground-truth" labels used for training. Our purpose was to investigate two ground-truths, the Cribari matrix and the Need for Trauma Intervention (NFTI), for labeling training data. Data was retrospectively collected from the institutional trauma registry and electronic medical record, including all pediatric patients (age <18 y) who triggered a trauma team activation (1/2014 - 12/2021). Three ground-truths were used to label training data: 1) Cribari (Injury Severity Score >15 = full activation), 2) NFTI (positive for any of 6 criteria = full activation), and 3) the union of Cribari+NFTI (either positive = full activation). Of 1,366 patients triaged by trained staff, 143 (10.47%) were considered under-triaged using Cribari, 210 (15.37%) using NFTI, and 273 (19.99%) using Cribari+NFTI. NFTI and Cribari+NFTI were more sensitive to under-triage in patients with penetrating mechanisms of injury (p = 0.006), specifically stab wounds (p = 0.014), compared to Cribari, but Cribari indicated over-triage in more patients who required prehospital airway management (p < 0.001), CPR (p = 0.017), and who had mean lower GCS scores on presentation (p < 0.001). The mortality rate was higher in the Cribari over-triage group (7.14%, n = 9) compared to NFTI and Cribari+NFTI (0.00%, n = 0, p = 0.005). To prioritize patient safety, Cribari+NFTI appears best for training a machine learning algorithm to predict trauma team activation level.

Informing Utstein-style reporting guidelines for prehospital thrombolysis: A scoping review

BackgroundRural Australians with acute myocardial infarction (AMI) face higher mortality rates due to limited access to specialised cardiac services. Paramedic-administered prehospital thrombolysis (PHT) has emerged as an alternative to primary percutaneous intervention (pPCI) for patients facing barriers or delays to cardiac care. There is variability in PHT practices among Australian ambulance services, lacking standardised definitions and outcome measures. The aim of this scoping review was to identify quality indicators and influencing factors associated with outcomes for patients receiving PHT. MethodsA systematic search of literature in SCOPUS and Academic Search Complete, CINAHL and Health Source: Nursing/Academic Edition databases via EBSCO (Health) was conducted following the Joanna Briggs Institute methodology. Peer-reviewed studies from the past decade were screened using search criteria relevant to prehospital thrombolysis and quality indicators. Data extraction was performed and themed using five domains from the Utstein-style template commonly known for standardised prehospital cardiac arrest reporting. ResultsAfter removing duplicates, the search yielded 3596 articles with 28 empirical studies meeting inclusion criteria for the review. These were primarily retrospective cohort studies performed in Australia, Canada and the United States. The scoping review identified 24 clinical quality indicators and factors related to Emergency Medical Service (EMS) systems, AMI recognition and ambulance dispatch, patient variables, PHT processes and patient outcomes. These findings correlate to the Donabedian structure-process-outcome quality of care model and have utility to inform future PHT reporting guidelines for jurisdictional ambulance services. ConclusionsGiven the variability in prehospital practice across Australian ambulance services, standardised reporting on quality indicators for PHT is needed. The Utstein-style template used to report data on pre-hospital cardiac arrest, trauma and airway management could be used for quality improvement in PHT. This review presents 24 quality indicators representing system, recognition and response, patient, process, and outcomes related to PHT. These results could be used to inform a future Delphi study and Utstein-like reporting guideline for prehospital thrombolysis.

Etomidate versus Ketamine as Prehospital Induction Agent in Patients with Suspected Severe Traumatic Brain Injury.

Severe traumatic brain injury is a leading cause of morbidity and mortality among young people around the world. Prehospital care focuses on the prevention and treatment of secondary brain injury and commonly includes tracheal intubation after induction of general anesthesia. The choice of induction agent in this setting is controversial. This study therefore investigated the association between the chosen induction medication etomidate versus S(+)-ketamine and the 30-day mortality in patients with severe traumatic brain injury who received prehospital airway management in the Netherlands. This study is a retrospective analysis of the prospectively collected observational data of the Brain Injury: Prehospital Registry of Outcomes, Treatments and Epidemiology of Cerebral Trauma (BRAIN-PROTECT) cohort study. Patients with suspected severe traumatic brain injury who were transported to a participating trauma center and who received etomidate or S(+)-ketamine for prehospital induction of anesthesia for advanced airway management were included. Statistical analyses were performed with multivariable logistic regression and inverse probability of treatment weighting analysis. In total, 1,457 patients were eligible for analysis. No significant association between the administered induction medication and 30-day mortality was observed in unadjusted analyses (32.9% mortality for etomidate versus 33.8% mortality for S(+)-ketamine; P = 0.716; odds ratio, 1.04; 95% CI, 0.83 to 1.32; P = 0.711), as well as after adjustment for potential confounders (odds ratio, 1.08; 95% CI, 0.67 to 1.73; P = 0.765; and risk difference 0.017; 95% CI, -0.051 to 0.084; P = 0.686). Likewise, in planned subgroup analyses for patients with confirmed traumatic brain injury and patients with isolated traumatic brain injury, no significant differences were found. Consistent results were found after multiple imputations of missing data. The analysis found no evidence for an association between the use of etomidate or S(+)-ketamine as an anesthetic agent for intubation in patients with traumatic brain injury and mortality after 30 days in the prehospital setting, suggesting that the choice of induction agent may not influence the patient mortality rate in this population.

Prehospital airway management by health workers in Riyadh City: A local survey

This study sought to determine the perception of healthcare workers (HCWs) about pre-hospital airway management and their experiences. Methods: This cross-sectional study was conducted among health workers at the emergency department of King Fahad Medical City in the capital of Saudi Arabia, Riyadh City. This study targeted physicians, nurses, paramedics, and respiratory therapists. Data were collected using an online questionnaire. The questionnaire included demographic characteristics, training, and experiences in airway management and a 5-item questionnaire to measure the perception of HCWs about airway management. Results: Of the 100 HCWs, 39% were doctors, and 37% were nurses. Approximately 23% had a poor experience with intubation. Traumatic injuries were the major difficulties involving airway management (44%). The overall perception of HCWs about prehospital airway management was good (68%), 31% were moderate, and only 1% were considered poor perception levels. No significant differences were observed between perception scores in relation to the demographic characteristics and experiences of HCWs in airway management (all p&amp;gt;0.05). Conclusion: Despite HCWs&amp;apos; good perception of prehospital airway management, some gaps have been identified mainly through intubation skills and experiences. This study provided evidence that perception towards prehospital airway management was not affected by profession, years of experience, regular practice of intubation, and airway management. Regular training should be implemented, with equipment and resources should be available to improve airway management and patient quality of care.

Evidence-Based Guidelines for Prehospital Airway Management: Methods and Resources Document

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

Prehospital and emergency department airway management of severe penetrating trauma in Sweden during the past decade

BackgroundPrehospital tracheal intubation (TI) is associated with increased mortality in patients with penetrating trauma, and the utility of prehospital advanced airway management is debated. The increased incidence of deadly violence in Sweden warrants a comprehensive evaluation of current airway management for patients with penetrating trauma in the Swedish prehospital environment and on arrival in the emergency department (ED).MethodsThis was an observational, multicenter study of all patients with penetrating trauma and injury severity scores (ISSs) ≥ 15 included in the Swedish national trauma register (SweTrau) between 2011 and 2019. We investigated the frequency and characteristics of prehospital and ED TI, including 30-day mortality and patient characteristics associated with TI.ResultOf 816 included patients, 118 (14.5%) were intubated prehospitally, and 248 (30.4%) were intubated in the ED. Patients who were intubated prehospitally had a higher ISS, 33 (interquartile range [IQR] 25, 75), than those intubated in the ED, 25 (IQR 18, 34). Prehospital TI was associated with a higher associated mortality, OR 4.26 (CI 2.57, 7.27, p < 0.001) than TI in the ED, even when adjusted for ISS (OR 2.88 [CI 1.64, 5.14, p < 0.001]). Hemodynamic collapse (≤ 40 mmHg) and low GCS score (≤ 8) were the characteristics most associated with prehospital TI. Traumatic cardiac arrests (TCAs) occurred in 154 (18.9%) patients, of whom 77 (50%) were intubated prehospitally and 56 (36.4%) were intubated in the ED. A subgroup analysis excluding TCA showed that patients with prehospital TI did not have a higher mortality rate than those with ED TI, OR 2.07 (CI 0.93, 4.51, p = 0.068), with OR 1.39 (0.56, 3.26, p = 0.5) when adjusted for ISS.ConclusionPrehospital TI was associated with a higher mortality rate than those with ED TI, which was specifically related to TCA; intubation did not affect mortality in patients without cardiac arrest. Mortality was high when airway management was needed, regardless of cardiac arrest, thereby emphasizing the challenges posed when anesthesia is needed. Several interventions, including whole blood transfusions, the implementation of second-tier EMS units and measures to shorten scene times, have been initiated in Sweden to counteract these challenges.

Supraglottic Airway Versus Tracheal Intubation for Airway Management in Out-of-Hospital Cardiac Arrest: A Systematic Review, Meta-Analysis, and Trial Sequential Analysis of Randomized Controlled Trials.

Given the uncertainty regarding the optimal approach for airway management for adult patients with out-of-hospital cardiac arrest (OHCA), we conducted a systematic review and meta-analysis to compare the use of supraglottic airways (SGAs) with tracheal intubation for initial airway management in OHCA. We searched MEDLINE, PubMed, Embase, Cochrane Library, as well as unpublished sources, from inception to February 7, 2023. We included randomized controlled trials (RCTs) of adult OHCA patients randomized to SGA compared with tracheal intubation for initial prehospital airway management. Reviewers screened abstracts, full texts, and extracted data independently and in duplicate. We pooled data using a random-effects model. We used the modified Cochrane risk of bias 2 tool and assessed certainty of evidence using the Grading Recommendations Assessment, Development, and Evaluation approach. We preregistered the protocol on PROSPERO (CRD42022342935). We included four RCTs ( n = 13,412 patients). Compared with tracheal intubation , SGA use probably increases return of spontaneous circulation (ROSC) (relative risk [RR] 1.09; 95% CI, 1.02-1.15; moderate certainty) and leads to a faster time to airway placement (mean difference 2.5 min less; 95% CI, 1.6-3.4 min less; high certainty). SGA use may have no effect on survival at longest follow-up (RR 1.06; 95% CI, 0.84-1.34; low certainty), has an uncertain effect on survival with good functional outcome (RR 1.11; 95% CI, 0.82-1.50; very low certainty), and may have no effect on risk of aspiration (RR 1.04; 95% CI, 0.94 to 1.16; low certainty). In adult patients with OHCA, compared with tracheal intubation, the use of SGA for initial airway management probably leads to more ROSC, and faster time to airway placement, but may have no effect on longer-term survival outcomes or aspiration events.

Abstract 234: Longitudinal Trends in Prehospital Advanced Airway Management in the United States

Background: While endotracheal intubation (ETI) is the most common prehospital advanced airway management technique in the United States (US), observations from clinical trials and the COVID-19 pandemic have motivated the broader use of supraglottic airways (SGA). The current national patterns of prehospital airway practices are unknown. We sought to describe longitudinal trends in Emergency Medical Services (EMS) advanced airway management in the US. Methods: We analyzed 2011-2021 data from ESO, a data set of US prehospital electronic health records. We identified all 911 events with attempted advanced airway management, determining the annual percentage receiving ETI and/or SGA attempts. We determined temporal trends using mixed effects regression. We stratified the analyses by condition (cardiac arrest, trauma, medical non-arrest) and age (adult vs. children [&amp;lt;18y]). Results: During the study period 355,532 patients underwent prehospital advanced airway management (annual incidence 9.0-10.0 per 1,000 911 events). Annual patients with SGA attempts increased almost three-fold (20.8% to 53.2%; p-trend&amp;lt;0.001), while annual patients with ETI attempts decreased (90.0% to 60.7%, p-trend&amp;lt;0.001). (Figure) Trends for cardiac arrest (SGA increased from 25.1% to 60.6%; ETI decreased from 87.3% to 54.7%) and trauma (SGA increased from 17.2% to 40.7%; ETI decreased from 90.5% to 71.8%) were similar. Advanced airway management in medical non-arrest patients remained stable (SGA 15.7% to 20.0%, p-trend=0.26; ETI 93.3% to 87.5%, p-trend=0.85). In children SGA attempts increased five-fold (11.2% to 50.9%, p-trend&amp;lt;0.001) while ETI attempts decreased (89.7% to 60.6%, p-trend&amp;lt;0.001). Conclusion: US prehospital advanced airway management practices have shifted, with marked increases in SGA and decreases in ETI attempts. These observations have critical implications for EMS care, training and system planning.

Prehospital Surgical Airway Management Skills in a Rural Emergency Medical Service System.

The objective of this study is to describe the education, training, and use of prehospital surgical airways in a rural Emergency Medical Service (EMS) system. We conducted an internet-based survey instrument of all advanced life support (ALS) EMS agencies in a seven-county rural EMS system in Pennsylvania. ALS agencies were queried regarding basic demographic information as well as the number of surgical airways performed in the previous 10 years as well as the education and training of EMS providers in surgical airways. The survey was completed by 11 of 20 ALS EMS agencies in our region (55% rate of return). The content and frequency of training varied considerably among EMS agencies. Only four prehospital surgical airways were performed during the study period. One patient survived to hospital discharge to home. Surgical airways are an infrequently performed procedure in the rural prehospital setting.There is no universally accepted standard for teaching or evaluating the competency of this potentially life-saving procedure. Further efforts to establish a core educational curriculum appear warranted.
