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
Supraglottic airway (SGA) devices provide effective conduits for oxygenation and ventilation and may offer protection from gastric aspiration. SGA devices are widely used by EMS clinicians as both rescue and primary airway management devices. While in common use for more than four decades, major developments in SGA education, science, and technology have influenced clinical strategies of SGA insertion and use in prehospital airway management for patients of all ages. NAEMSP recommends:SGAs have utility as a primary or secondary EMS airway intervention. EMS agencies should select SGA strategies that best suit available resources and local clinician skillset, as well as the nature of their clinical practice setting.EMS agencies that perform endotracheal intubation must also equip their clinicians with SGA devices and ensure adequate training and competence.In select situations, drug-assisted airway management may be used by properly credentialed EMS clinicians to facilitate SGA insertion.Confirmation of initial and continuous SGA placement using waveform capnography is strongly encouraged as a best practice.When it is functioning properly, EMS clinicians should refrain from converting an SGA to an endotracheal tube. The decision to convert an SGA to an endotracheal tube must consider the patient's condition, the effectiveness of SGA ventilations, and the clinical context and course of initial SGA insertionSGA training, competency, and clinical use must be continuously evaluated by EMS agencies using focused quality management programs.

Abstract
OBJECTIVE Respiratory Therapists (RTs) are some of the first staff to arrive at in-hospital incidents where cardiopulmonary resuscitation (CPR) is needed, yet at some facilities, their ability to intubate is limited by hospital scope of practice. During the intubation process, CPR is often interrupted which could potentially increase the likelihood of adverse patient outcomes. Training RTs to secure the airway using non-intubation methods may reduce or eliminate time for CPR interruptions and allow for earlier continuous/uninterrupted chest compressions. DESIGN A pilot study was developed to assess the effectiveness of a new policy for RT scope of practice. METHODS RTs were trained for supraglottic airway device placement prior to procedure initiation. After each device insertion event, RTs completed a written survey. Time between cardiac arrest and device insertion, number of insertion attempts, ease of placement, technical specifications of the device, complications, and survival were compiled and compared between supraglottic airway device and endotracheal tube (ETT) placement. RESULTS Procedural information from 23 patients who received a supraglottic airway device during the trial was compared to retrospective data of CPR events requiring intubation from the previous year. Time between initiation of cardiac arrest and advanced airway placement decreased significantly (p < 0.0001) when RTs placed the supraglottic airway device (4.7 min) versus ETT at CPR events the previous year (8.6 min). Device-associated complications were minimal and patient mortality was the same regardless of device. CONCLUSION We propose that more RTs should be trained to insert supraglottic airway devices during inpatient CPR events.

Abstract
OBJECTIVES We aimed to compare the procedural success and intervention durations regarding various airway access skills in moving and stationary ambulance simulations. MATERIAL AND METHODS An ambulance simulator was used to simulate the moving ambulance environment, and a standard manikin was used for airway simulation. The study included 38 paramedics and paramedic students. In stationary and moving environments, a classical endotracheal intubation with a stylet, an intubation with a gum elastic bougie (GEB), a laryngeal mask airway (LMA), and a laryngeal tube (LT) were applied randomly. The cuff inflation duration, the duration until the first ventilation, and the intubation success were assessed. RESULTS There was no difference in terms of success and intubation durations of the four methods in moving and stationary environments. In both environments, the LT and LMA were inserted most rapidly (p < 0.001). There was no difference in the intubation duration and the success among the supraglottic methods. In moving and stationary environments, the intubation with a classic stylet was faster than the intubation with a GEB. The use of a GEB did not increase the intubation success. CONCLUSIONS In this simulation study, the moving environment did not affect the duration or success of the endotracheal intubation. Supraglottic methods were applied more quickly in both moving and stationary environments. A GEB was used successfully by practioners with no previous experience; however, the duration of the intubation was longer.

Abstract
INTRODUCTION This study compared first-attempt placement success rates of the King LTS-D as a primary airway for patients requiring medication-assisted airway management (MAAM) against historical controls. SETTING Rotor-wing division of a single critical care transportation company METHODS 53 providers (RNs/EMT-P) consented to participation and were trained in the use of the King LTS-D. All patients in need of MAAM per agency treatment guidelines were screened for inclusion and exclusion criteria. After each placement attempt, providers completed data collection via telephone. The primary endpoint was comparison of first-attempt placement success rate between the King LTS-D and historical control endotracheal intubation (ETI) MAAM patients. Overall placement success, time to placement, pre- and post-placement SaO2, ETCO2 at 2 minutes after placement, and complications were also analyzed. RESULTS 38 patients received rapid sequence intubation with the King LTS-D by 23 of 58 consented providers. First-attempt success rate was 76% (29/38), with an overall success rate of 84% (32/38). The primary endpoint analysis showed no difference in first-attempt success rate between historical control ETI MAAM data and King LTS-D (71% vs 76%; OR = 0.1.34 [95% CI Intubation time to insertion was 26 seconds (IQR = 12-46). Pre- and post-insertion SaO(1)2 values were 88.9 ± 12.6% and 92.1 ± 12.7%, respectively. Mean ETCO2 at 2 minutes after placement was 34.8 ± 4.0. Vomit in the patient's airway was the most frequently reported complication (46%). CONCLUSION Success rates with the King LTS-D were not significantly different from historical control ETI data. Time to placement was comparable to previous reports.

Abstract
Six different supraglottic airway devices: Combitube™, laryngeal mask airway, intubating laryngeal mask airway (Fastrach™), i-gel™, Laryngeal Tube™ and Pro-Seal™ laryngeal mask airway were assessed by 58 paramedic students for speed and ease of insertion in a manikin, whilst wearing either chemical, biological, radiation, nuclear-personal protective equipment (CBRN-PPE) or a standard uniform. All devices took significantly longer to insert when wearing CBRN-PPE compared with standard uniform (p < 0.001). In standard uniform, insertion time was shorter than 45 s in 90% of attempts for all devices except the Combitube, for which 90% of attempts were completed by 53 s. Whilst wearing CBRN-PPE the i-gel was the fastest device to insert with a mean (SD (95% CI)) insertion time of 19 (8 (17-21))s, p < 0.001, with the Combitube the slowest with mean (65 (23 (59-71))s. Wearing of CBRN-PPE has a negative impact on supraglottic airway insertion time.

Abstract
OBJECTIVE To determine whether prehospital providers can successfully place a pediatric King laryngeal tube (LT-D) and ventilate a Laerdal SimBaby pediatric simulator during a respiratory arrest simulation. METHODS We studied the ability of 45 paramedics and flight nurses to place the pediatric King LT-D in a SimBaby manikin. For the purposes of this study, paramedics and flight nurses were considered equivalent, because in this air medical system they have the same scope of practice in regard to airway skills. Because the participants had previous training and field experience with the adult King LT-D, we limited pediatric King LT-D training to our standard adult training plus selecting the correct size and inflation volumes for the device. Outcomes included rate of successful pediatric King LT-D placement, number of attempts to correctly place the tube, and time to first adequate ventilation. The subjects were evaluated on airway management using an 11-point skill test. A score of 8 or greater (≥ 73%) was considered passing. The subjects indicated their perceptions and preferences for the pediatric King LT-D using a five-point Likert scale. Data were analyzed using descriptive statistics. RESULTS Crew members successfully placed the pediatric King LT-D 95.5% (43/45) of the time. The median number of attempts was one. Four subjects required a second attempt; two of these subjects failed at placement. Mean time to placement was 34 seconds (95% confidence interval [CI]: 26.4-67.3 sec). Ninety percent of the participants (40/45) successfully completed the skill test, with a mean score of 78.2% (95% CI: 73.6-82.7). The subjects strongly agreed that their previous training on the adult King LT-D and using it in the field had adequately prepared them to use the pediatric King LT-D. The subjects agreed that the pediatric King LT-D was easier to place than a pediatric endotracheal tube; they strongly agreed that they would use the pediatric King LT-D as an alternative airway. The participants disagreed that they would prefer the pediatric King LT-D as a primary means of securing pediatric airways. CONCLUSIONS The pediatric King LT-D was quickly and reliably placed. Providers perceived the pediatric King LT-D to be easier to use than pediatric endotracheal intubation in this setting.

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
PURPOSE OF REVIEW This review will analyze and comment on selected recent literature pertaining to airway management and initial fluid resuscitation in the trauma patient. It will also review airway devices currently being used in the trauma setting. RECENT FINDINGS Although a recent study has questioned the efficacy of manual inline immobilization, this technique continues to be endorsed by trauma guidelines and is safely used in most trauma centers. Clinicians have also incorporated the use of videolaryngoscopy and other adjuncts for difficult airway management in trauma patients. However, no single airway management tool has proven to be superior in this setting. Crystalloid solutions remain frontline therapy for the initial resuscitation of the hemorrhagic trauma patient, as studies with hypertonic saline and vasopressors have not shown superior results. Conversely, increased amounts of fresh frozen plasma and fibrinogen have been reported to increase survival in trauma patients. SUMMARY As trauma continues to be a major cause of morbidity and mortality worldwide, the use of newer airway adjuncts needs to be specifically investigated in trauma patients, as this population frequently has airway management difficulties. Further research is also required to elucidate the type and amount of fluid that will provide an adequate organ perfusion without increasing nonsurgical bleeding.
