Tracheal intubation is a critical step in securing the patient's airway in a variety of emergent and non-emergent settings. Difficulties and complications may arise with this procedure, and alternative laryngoscopes that use video technology have been designed to improve visibility when airway difficulty is predicted or encountered. These devices may be flexible or rigid in design for the purpose of assisting in intubations, especially expected difficult intubations. Video laryngoscopes have been advertised as being able to reduce difficulty, failure, trauma and other complications compared with direct laryngoscopy...

BACKGROUND: In patients with predictive features associated with easy direct laryngoscopy, videolaryngoscoy with the GlideScope has been shown to require less force when compared with Macintosh direct laryngoscopy. OBJECTIVE: The aim of this study was to compare forces applied with Glidescope vs. Macintosh laryngoscopes in patients with predictive features associated with difficult direct laryngoscopy. DESIGN: A prospective randomised study...

We herein report two expected difficult intubation cases that failed with an angulated-type video laryngoscope (C-MAC D-blade) and were rescued with a channelled-type Airtraq® device. The common signs and characteristics which indicated difficult ventilation and intubation in these patients were Mallampati 4 (with phonation), mandibular protrusion of B, obstructive sleep apnoea disorder, male gender, and thick neck (>46 cm). We had aids ready in the operating theatre for the anticipated difficult intubation...

During laryngoscopy, the laryngoscope blade sometimes comes in contact with the teeth, fracturing or dislocating them. However, no studies have compared the effects of newly marketed video laryngoscopes and the Macintosh laryngoscope (Mac) on teeth. In this study, we measured and compared the force exerted on the teeth of an intubating manikin by the Mac, the Airway Scope (Pentax), and the McGrath MAC (Covidien). The mean force exerted was 141.1 ± 15.7 kg by the Mac, 39.2 ± 10.3 kg by the Airway Scope, and 48...

BACKGROUND: In infants, securing the airway is time-critical because of anatomical and physiological differences related to airway management in children less than 1 year old. The aim of this study was to compare the time to ventilation using two different hyperangulated video laryngoscope blades with the time to ventilation via conventional direct laryngoscopy in a normal airway [NA] and in a simulated difficult airway [DA]. METHODS: This study was a comparative, bicentric, open-label, randomized controlled evaluation...

BACKGROUND: Novice clinicians who have little or no clinical experience in tracheal intubation occasionally need a long time to perform the procedure when using a large curved blade. They also have a lower tracheal intubation success rate, especially in emergency situations, such as cardiac arrest, than experienced practitioners. This study aimed to investigate whether the size of the curved laryngoscope blade affects the outcomes of tracheal intubation performed by incoming interns on a manikin model...

Introduction: Intubation can sometimes be difficult in patients with lesions in the mouth floor. Ameloblastoma is a frequently encountered tumor of the maxillofacial area. An extensive lesion might occupy the floor of the mouth, prevent displacement of the tongue, limiting the space for inserting a laryngoscope blade and resulting in difficult intubation even with fiberoptic bronchoscopy. Case presentation: A 66-year-old man (67 kg; 171 cm) with a mental swelling was diagnosed with ameloblastoma and scheduled for surgical resection...

BACKGROUND: In patients with an unstable cervical spine, maintenance of cervical immobilization during tracheal intubation is important. In McGrath videolaryngoscopic intubation, lifting of the blade to raise the epiglottis is needed to visualize the glottis, but in patients with an unstable cervical spine, this can cause cervical spine movement. By contrast, the Optiscope, a rigid video-stylet, does not require raising of the epiglottis during tracheal intubation. We therefore hypothesized that the Optiscope would produce less cervical spine movement than the McGrath videolaryngoscope during tracheal intubation...

Background: The goal of this study was to determine whether motion parameters during laryngoscopy in a manikin differed with experienced operators versus novice trainees and whether motion measurements would predict trainee outcomes when intubating patients. Methods: Motion, force, and duration of laryngoscopy on a manikin were compared in two separate experiments between beginning anesthesiology residents (CA1) and anesthesiologists with more than 24 months of anesthesiology training (CA3 or attendings)...

BACKGROUND: It is very rare but challenging to perform emergency airway management for accidental extubation in a patient whose head and neck are fixed in the prone position when urgently turning the patient to the supine position would be unsafe. The authors hypothesized that tracheal intubation with a videolaryngoscope would allow effective airway rescue in this situation compared with a supraglottic airway device and designed a randomized crossover manikin study to test this hypothesis...

STUDY OBJECTIVE: The C-MAC laryngoscope (C-MAC) is a videolaryngoscope that uses a modified Macintosh blade. Although several anecdotal reports exist, it remains unclear whether the C-MAC is superior to the Macintosh laryngoscope for tracheal intubation in the adult population. DESIGN: Systematic review, meta-analysis. SETTING: Operating room, intensive care unit. MEASUREMENTS: For inclusion in our analysis, studies had to be prospective randomised trials which compared the C-MAC with the Macintosh laryngoscope for tracheal intubation in the adult population...

Importance: The tracheal tube introducer, known as the bougie, is typically used to aid tracheal intubation in poor laryngoscopic views or after intubation attempts fail. The effect of routine bougie use on first-attempt intubation success is unclear. Objective: To compare first attempt intubation success facilitated by the bougie vs the endotracheal tube + stylet. Design, Setting, and Patients: The Bougie Use in Emergency Airway Management (BEAM) trial was a randomized clinical trial conducted from September 2016 through August 2017 in the emergency department at Hennepin County Medical Center, an urban, academic department in Minneapolis, Minnesota, where emergency physicians perform all endotracheal intubations...

Objective Insertion of a nasogastric tube (NGT) in patients who have been intubated with an endotracheal tube while under general anesthesia can cause difficulties and lead to complications, including hemorrhage. A visualization-aided modality was recently used to facilitate NGT insertion. Some studies have focused on the role of modified Magill forceps, which have angles similar to those of the GlideScope blade (Verathon, Bothell, WA, USA). Methods Seventy patients were divided into a control group (Group C) and an experimental group (GlideScope and modified Magill forceps, Group M)...

Background: The incidence of difficult intubation (DI) in obese patients may reach a two-digit figure. No studies have assessed the effect of primary use of special intubation devices on lowering the incidence of DI. We assessed the effect of primary selection of special intubation techniques on the incidence of DI in patients with a BMI of 35 kg/m2 or higher. Patients and methods: Data from 546 patients with a BMI of 35 kg/m2 or higher who underwent bariatric surgery at Wolfson Medical Center from 2010 through 2014 was retrospectively extracted and analyzed for demographics, predictors of DI and intubation techniques employed...

INTRODUCTION: Duchenne muscular dystrophy (DMD) is an x linked recessive disorder. Long term prognosis is ominous, with development of respiratory distress and cardiomyopathy in advanced stage of the disease and expected death in the teens-to-mid 20s due to respiratory or cardiac failure. Peri-operative management of this patients is challenging due to difficult airway anatomy (macroglossia, limited neck and mandibular mobility). Additionally, they are at risk of developing malignant hyperthermia, rhabdomyolysis and hyperkalemic cardiac arrest when exposed to halogenated inhalational anaesthetics and depolarizing muscle relaxants...

BACKGROUND: Epistaxis, or nasal bleeding, is a common complication after nasotracheal intubation (NTI). Because such bleeding is likely related to trauma during intubation, use of fiberoptic visualization and guidance rather than direct laryngoscopy may affect the incidence and severity of epistaxis. We compared the incidence of epistaxis after NTI using a fiberoptic versus a direct laryngoscopy approach. METHODS: Seventy patients who were able to breathe easily through unobstructed nostrils and required NTI as part of their anesthetic management were recruited...

Head and neck position is one of the factors which can be associated with difficult videolaryngoscopy and tracheal intubation. This prospective randomised clinical trial compared 'sniffing' and neutral positions using a channelled (KingVision® ) and a non-channelled (C-MAC® D-blade) videolaryngoscope in 200 adult patients randomly allocated into four groups (KingVision 'sniffing', KingVision neutral, C-MAC 'sniffing' and C-MAC neutral). The primary outcome was the ease of tracheal intubation using the modified intubation difficulty scale (mIDS) score...

Background: Although videolaryngoscopes improve glottic visualization, their actual usefulness in intubation is not yet established. Aims: The primary objective was to compare the ease of oral intubation with the use of 60° angled styletted endotracheal tube versus that performed over bougie inserted under videolaryngoscopic guidance. The secondary objectives were assessment of incidence of airway loss, hemodynamic changes, and time and number of attempts at intubation...
