Extraglottic device

PURPOSE: 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. METHODS: We included cases only from German hospitals with a minimum Abbreviated Injury Scale score ≥ 2 and age ≥ 16 years...

BACKGROUND: Tracheal intubation is the gold standard for airway management in emergency medicine, but more difficult to apply for inexperienced individuals than laryngeal mask airway (LMA). OBJECTIVE: The aim of our study was to investigate if inexperienced individuals are able to secure the airway with the help of LMA after a short introduction. A second aim was to evaluate Thiel-fixed specimens against unfixed ones. METHODS: In a body donor model, LMA application was evaluated between medical students without previous airway experience and anesthesiologists by comparing the sealing of the larynx using a water column applied to the esophagus...

BACKGROUND AND AIMS: A variety of extraglottic airway devices (EADs) are available. Main concerns with EADs are protection against aspiration and ability to ventilate patients with high airway pressures. Baska mask meets these criteria and is the only third-generation device available for clinical use. METHODS: After institutional ethics committee approval and informed consent were obtained, this prospective study was performed in 100 adult patients undergoing surface surgeries at a tertiary referral centre...

INTRODUCTION: Airway management is a critical component of the management of emergency department (ED) patients. The ED airway literature primarily focuses upon endotracheal intubation; relatively less is known about the ED use of extraglottic devices (EGDs). The goal of this study was to describe the frequency of use, success, and complications for EGDs among ED patients. METHODS: The National Emergency Airway Registry (NEAR) is a prospective, multi-center, observational registry...

BACKGROUND: Although airway management for paramedics has moved away from endotracheal intubation towards extraglottic airway devices in recent years, in the context of COVID-19, endotracheal intubation has seen a revival. Endotracheal intubation has been recommended again under the assumption that it provides better protection against aerosol liberation and infection risk for care providers than extraglottic airway devices accepting an increase in no-flow time and possibly worsen patient outcomes...

Cricothyrotomy represents the final approach to secure the airway, in the course of which less invasive measures have failed. It can also primarily be carried out to establish a secure airway. This is essential to protect the patient from a significant hypoxia. This is a cannot ventilate-cannot oxygenate (CVCO) situation, which presumably all colleagues in emergency intensive care medicine and anesthesia have already been confronted with. Evidence-based algorithms for the management of a difficult airway and CVCO have been established...

OBJECTIVE: Supraglottic airway devices are increasingly used during the resuscitation of out-of-hospital cardiac arrest (OHCA) patients in the United States and worldwide. In this study, we aimed to compare the neurologic outcomes of OHCA patients managed with the King Laryngeal Tube (King LT) to the neurologic outcomes of patients managed with the iGel. METHODS: We used the Cardiac Arrest Registry to Enhance Survival (CARES) public use research dataset for our analysis...

INTRODUCTION: Airway obstruction is the second leading cause of death on the battlefield. The harsh conditions of the military combat setting require that devices be able to withstand extreme circumstances. Military standards (MIL-STD) testing is necessary before devices are fielded. We sought to determine the ability of supraglottic airway (SGA) devices to withstand MIL-STD testing. METHODS: We tested 10 SGA models according to nine MIL-STD-810H test methods. We selected these tests by polling five military and civilian emergency-medicine subject matter experts (SMEs), who weighed the relevance of each test...

The Spritztube (ST) is an extraglottic airway device developed for humans. The aim of the study was to design an ST for rabbits and to evaluate its feasibility. The study was divided into two phases. Phase I: anatomical study on 12 rabbit cadavers to design 2 STs (8 and 10 Ch, external diameter) for rabbits. Phase II: fourteen privately owned rabbits were anaesthetised, and intubation was attempted using a ST. Tube size, the method for confirming the correct positioning, the number of attempts, the time needed for the correct positioning of the ST and complications were recorded...

INTRODUCTION: Airway obstruction is the second leading cause of potentially survivable death on the battlefield. The Committee on Tactical Combat Casualty Care (CoTCCC) has evolving recommendations for the optimal supraglottic airway (SGA) device for inclusion to the medics' aid bag. METHODS: We convened an expert consensus panel consisting of a mix of 8 prehospital specialists, emergency medicine experts, and experienced combat medics, with the intent to offer recommendations for optimal SGA selection...

Large-scale combat and multi-domain operations will pose unprecedented challenges to the military healthcare system. This scoping review examines the specific challenges related to the management of airway compromise, the second leading cause of potentially preventable death on the battlefield. Closing existing capability gaps will require a comprehensive approach across all components of the Joint Capabilities Integration Development System. In this, we present the case for a change in doctrine to selectively provide definitive airway management in prehospital settings to maximize the effectiveness of limited resources...

AIM OF THE WORK: To evaluate the practical implementation of the COVID-19 resuscitation guidelines in Germany one year after their publication. MATERIAL AND METHODS: In an online survey between April and May 2021 participants were asked about awareness of COVID-19 resuscitation guidelines, corresponding training, the resuscitation algorithm used and COVID-19 infections of emergency medicine personnel associated with COVID-19 resuscitation...

Spritztube® is a new supraglottic airway device that allows either extraglottic ventilation or orotracheal intubation with the same device. The aim of the present report is to provide the first radiologic images of the Spritztube in situ in a living human and to assess the depth of insertion and its anatomical relationships in vivo. We present the case of a 55-year-old man who was admitted to our centre to perform an interventional neuroradiological procedure. We obtained and analysed radiologic images of the head and neck of an adult patient to ascertain the position of the cuffs of the Spritztube relative to different anatomic structures...

Extraglottic devices (EGDs) are important tools for airway management in the prehospital and transport medicine environment. EGDs may be used as either a primary airway or rescue device depending on the provider skill level or patient circumstances. Although EGDs do not provide a definitive airway, they can facilitate oxygenation and ventilation in select patients. This is particularly important in the remote or austere environment when difficult airways are infrequently encountered. This case report details the prolonged use of an EGD during air medical transport from a rural Alaskan medical clinic to a large academic tertiary receiving facility, with the total time until definitive airway placement of approximately 9 hours...

BACKGROUND: The LMA Fastrach (LMA North America, Inc; hereafter termed the intubating laryngeal mask airway [ILMA]) is an extraglottic device designed to facilitate endotracheal intubation. After the endotracheal tube is placed through the lumen of the ILMA into the trachea, the ILMA is removed, using a proprietary stabilizer rod to hold the tube in place. DISCUSSION: The traditional method of ILMA removal is not optimized for the critically ill patient. It requires the use of unfamiliar equipment, exposes the patient to a significant period without ventilation, and risks tube dislodgement...

BACKGROUND: The administration of sedation and neuromuscular blockade to facilitate extraglottic device (EGD) placement is known as rapid sequence airway (RSA). In the emergency department (ED), EGDs are used largely as rescue devices. In select patients, there may be significant advantages to using EGDs over laryngoscopy as the primary airway device in the ED. OBJECTIVE: Our study sought to describe the practice of RSA in the ED, including rates of successful oxygenation, ventilation, and complications from EGD use...

Extraglottic airway devices (EAD) have revolutionized the perioperative airway management. The accuracy of clinical tests to identify malposition has been questioned by recent studies where fibreoptic evaluation identified various malpositions that were undiagnosed by a clinical test. Ultrasound (USG) has evolved to guide various airway interventions. However, USG is under-evaluated in the assessment of the EADs position. Our study aimed to compare clinical versus USG assessment of optimal placement of ProSeal laryngeal mask airway (PLMA)...

Compared to intubation with a cuffed endotracheal tube, extraglottic airway devices (EGDs), such as laryngeal mask airways, are considered less definitive ventilation conduit devices and are therefore often exchanged via endotracheal intubation (ETI) prior to obtaining CT images. With more widespread use and growing comfort among providers, reports have now described use of EGDs for up to 24 h including cases for which clinicians obtained CT scans with an EGD in situ. The term EGD encompasses a wide variety of devices with more complex structure and CT appearance compared to ETI...
