endotracheal supraglottic

Supraglottic airway devices (SADs) have become an essential tool in airway management. Over the past three decades, these devices have been increasingly adopted as an alternative to face mask ventilation and/or endotracheal intubation. The range of proposed uses and features have increased significantly. They are used in pre- and in-hospital settings, elective and emergency anesthesia, in spontaneously breathing and ventilated patients, as conduits for intubation, as a bridge to extubation and for airway rescue...

BACKGROUND: While guidelines mentioned supraglottic airway management in the case of out-of- hospital cardiac arrest, robust data of their impact on the patient outcome remain scare and results are inconclusive. METHODS: To assess the impact of the airway strategy on the patient outcome we prospectively enrolled 2224 individuals suffering cardiac arrest who were treated by the Viennese municipal emergency medical service. To control for potential confounders, propensity score matching was performed...

BACKGROUND: Prehospital airway management increasingly involves supraglottic airway insertion and a paucity of data evaluates outcomes in trauma populations. We aim to describe definitive airway management in traumatically injured patients who necessitated prehospital supraglottic airway insertion. METHODS: We performed a single institution retrospective review of multisystem injured patients (≥15years) that received prehospital supraglottic airway insertion during 2009 to 2016...

BACKGROUND: The forced oscillation technique (FOT) is a non-invasive means of measuring respiratory resistance and reactance. We tested our hypothesis that endotracheal intubation would cause more substantial preoperative increases in FOT parameters than a supraglottic airway device (SGD). METHODS: Forty patients requiring general anesthesia and mechanical ventilation for transurethral bladder tumor resection underwent spirometry the day before surgery. Forced oscillation was measured using a MostGraph-01 device the day before surgery and immediately after removal of the airway adjunct...

BACKGROUND: Although human and equipment resources, proper training, and the verification of endotracheal intubation are vital elements of difficult airway management (DAM), their availability in Japanese emergency departments (EDs) has not been determined. How ED type and patient volume affect DAM preparation is also unclear. We conducted the present survey to address this knowledge gaps. METHODS: This nationwide cross-sectional study was conducted from April to September 2016...

BACKGROUND AND AIMS: Ambu(®) AuraGain™ (AG) (Ambu, Ballerup, Denmark) is a supraglottic device which has a design facilitating its use as a conduit for intubation. We designed this prospective observational study to assess the ease of AG placement in paralysed patients, determine its position and alignment to the glottis and assess its utility as a conduit for intubation. METHODS: One hundred patients, aged 18-60 years, American Society of Anesthesiologists physical status I-II, undergoing elective surgery under general anaesthesia were included in the study...

BACKGROUND: An obstructive neck lesion presents an airway challenge for any emergency physician. Retrograde intubation is an infrequently used airway alternative that can be employed in the difficult airway algorithm that requires little training and is less invasive than surgical cricothyrotomy. CASE REPORT: We report a case of a 31-year-old male patient who presented with respiratory distress progressing to respiratory failure from upper airway obstruction. The patient had significant tracheal thickening at the level of the thyroid gland based on a computed tomography report from 3 weeks prior to his presentation...

OBJECTIVE: To compare odds of survival to hospital discharge among pediatric out-of-hospital cardiac arrest (OHCA) patients receiving either bag-valve-mask ventilation (BVM), supraglottic airway (SGA) or endotracheal intubation (ETI), after adjusting for the propensity to receive a given airway intervention. METHODS: Retrospective cohort study using the Cardiac Arrest Registry to Enhance Survival (CARES) database from January 1 201-December 31, 2015. The CARES registry includes data on cardiac arrests from 17 statewide registries and approximately 55 additional US cities...

OBJECTIVES: Although endotracheal intubation, surgical crossfield intubation, and jet ventilation are standard techniques for airway management in tracheal resections, there are also reports of new approaches, ranging from regional anesthesia to extracorporeal support. The objective was to outline the entire spectrum of new airway techniques. DESIGN: The literature databases PubMed/Medline and the Cochrane Library were searched systematically for prospective and retrospective trials as well as case reports on tracheal resections...

OBJECTIVE: Airway management during endoscopic surgical treatment of supraglottic and pharyngeal stenosis is often challenging and can be accomplished by various means, including tracheostomy, jet ventilation, or direct laryngoscopy. We describe CO2 laser excision of supraglottic-pharyngeal stenosis using intubationless Optiflow high-flow nasal cannula (HFNC). METHODS: A 55-year-old male presented with dyspnea and dysphagia secondary to severe supraglottic-pharyngeal stenosis in the setting of previous chemoradiation for a T0N2aM0 squamous cell carcinoma...

BACKGROUND: 911 Emergency Medical Services (EMS) systems utilize supraglottic devices for either primary advanced airway management, or for airway rescue following failed attempts at direct laryngoscopy endotracheal intubation. There is, however, limited data on objective confirmation of supraglottic airway placement in the prehospital environment. Furthermore, the ability of EMS field providers to recognize a misplaced airway is unknown. METHODS: Retrospective review of patients who underwent airway management using the King LTS-D supraglottic airway in a large urban EMS system, between 3/1/15-9/30/2015...

BACKGROUND: The aim of this study was to examine the application of the Eschmann tracheal tube introducer (ETTI) with 4 types of supraglottic airway devices (SADs) using a child-manikin. METHODS: A total of 79 paramedics were asked to exchange the 4 SADs for an endotracheal tube with the ETTI in 3 different scenarios using a randomized crossover study format: normal airway without chest compression; normal airway with uninterrupted chest compression; and difficult airway with uninterrupted chest compression...

BACKGROUND: Transoral videolaryngoscopic surgery (TOVS) was developed as a new distinct surgical procedure for hypopharyngeal cancer (HPC) and supraglottic cancer (SGC) staged at up to T3. However, long-term treatment outcomes of TOVS remain to be validated. METHODS: Under a straight broad intraluminal view provided by combined use of a distending laryngoscope and a videolaryngoscope, we performed en bloc tumor resection via direct bimanual handling of the ready-made straight-form surgical instruments and devices...

BACKGROUND: The EasyTube (EzT) is a supraglottic airway device that is used for emergency airway situations. Ventilation during general anesthesia should also be feasible, but literature on the EzT is scarce. We evaluated the EzT in comparison with the endotracheal tube (ETT) in its use during general anesthesia in a comparative study. METHODS: A total of 400 patients with American Society of Anesthesiologists (ASA) physical status I to II scheduled for minor surgery in 4 centers were randomized for ventilation via the ETT or EzT...

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...

INTRODUCTION: Endotracheal intubation (ETI) in the prehospital setting poses unique challenges where multiple ETI attempts are associated with adverse patient outcomes. Early identification of difficult ETI cases will allow providers to tailor airway-management efforts to minimize complications associated with ETI. We sought to derive and validate a prehospital difficult airway identification tool based on predictors of difficult ETI in other settings. METHODS: We prospectively collected patient and airway data on all airway attempts from 16 Advanced Life Support (ALS) ground emergency medical services (EMS) agencies from January 2011 to October 2014...

BACKGROUND: The EasyTube® (EzT) is a supraglottic airway device (SAD) enabling ventilation irrespective of its placement into the esophagus or trachea. Data obtained on SADs from multicenter studies, performed in highly specialized centers cannot always be transferred to other sites. However, data on comparability of different sites are scarce. This study focused on inter-site variability of ventilatory and safety parameters during general anesthesia with the EzT. METHODS: 400 patients with ASA physical status I-II undergoing general anesthesia for elective surgery in four medical centers (EzT group (n = 200), ETT group (n = 200))...

BACKGROUND: Supraglottic airway devices commonly are used for securing the airway during general anesthesia. Occasionally, intubation with an endotracheal tube through a supraglottic airway is indicated. Reported success rates for blind intubation range from 15 to 97%. The authors thus investigated as their primary outcome the fraction of patients who could be intubated blindly with an Air-Qsp supraglottic airway device (Mercury Medical, USA). Second, the authors investigated the influence of muscle relaxation on air leakage pressure, predictors for failed blind intubation, and associated complications of using the supraglottic airway device...

This is a rare presentation of a morbidly obese male with a massive retropharyngeal goiter causing laryngeal compressive symptoms and unique airway management challenges. Flexible laryngoscopy revealed a retropharyngeal mass circumferentially compressing the oropharynx and supraglottis and preventing the visualization of the glottis. Awake tracheostomy was performed before total thyroidectomy. Airway compression from a goiter typically results from substernal extension, which usually does not cause difficulty with endotracheal intubation...

OBJECTIVE: To compare airway management during induction of anaesthesia, spontaneous ventilation (SV) and controlled mechanical ventilation (CMV), using an endotracheal tube (ETT), laryngeal mask (LM), rabbit-specific supraglottic airway device (v-gel) or facemask (FM). STUDY DESIGN: Prospective randomized crossover experiment. ANIMALS: Ten New Zealand White rabbits. METHODS: After premedication, rabbits were randomly allocated to four groups: 1) ETT; 2) LM; 3) v-gel or 4) FM...
