Intubation with glidescope in trauma

Potentially difficult airways warrant the use of airway adjuncts, which, if not used with caution, can cause trauma to the oral cavity. Although most operators are familiar with modern airway adjuncts, as they are not routinely used, adverse events can occur. Since its introduction, a video laryngoscope (VL) has been lauded as a necessary instrument for airway management in and out of the operating room. This case report highlights right tonsillar tissue perforation with a GlideScope® VL (Verathon Incorporated, Bothell, Washington, USA), requiring primary closure by an otolaryngologist...

BACKGROUND: Airway management can be challenging in neonates and infants. The Pierre Robin sequence (PRS) is a condition characterized by micrognathia, glossoptosis and airway obstruction. The airway management of these patients poses great challenges for anesthesiologists and pediatricians alike. To date, there has been no direct comparison of the hyperangulated GlideScope® Spectrum LoPro (GLP), the straight GlideScope® Spectrum Miller (GSM), a conventional Macintosh (MC) and a conventional Miller blade (ML) in patients with PRS...

BACKGROUND: Establishment of a secure airway is a critical part of neonatal resuscitation in the delivery room and the neonatal intensive care unit. Videolaryngoscopy has the potential to facilitate successful endotracheal intubation, and decrease adverse consequences of a delay in airway stabilization. Videolaryngoscopy may enhance visualization of the glottis and intubation success in neonates. This is an update of a review first published in 2015, and updated in 2018. OBJECTIVES: To determine the effectiveness and safety of videolaryngoscopy compared to direct laryngoscopy in decreasing the time and attempts required for endotracheal intubation and increasing the success rate on first intubation attempt in neonates (0 to 28 days of age)...

OBJECTIVES: To quantify dental forces during double-lumen tube intubations with different laryngoscopy techniques. DESIGN: Experimental biomechanical mannequin study. SETTING: Two German university hospitals. PARTICIPANTS: One hundred four anesthesiologists with varying levels of experience. INTERVENTIONS: Participants performed a sequence of intubations on a mannequin equipped with hidden forces sensors in the maxillary incisors...

Background: Video laryngoscopy has been associated with some orotracheal intubations and enhances the glottic view at time of laryngoscopy and the success rate of the intubation in patients from the emergency department and the intensive care unit. In usual cases, direct laryngoscopy is performed among the patients from the emergency department or the intensive care unit. In this systematic review and meta-analysis, we draw the comparison between the video laryngoscopy and direct laryngoscopy for the emergency orotracheal intubation...

BACKGROUND: Video laryngoscopy is an effective tool in the management of difficult pediatric airway. However, evidence to guide the choice of the most appropriate video laryngoscope (VL) for airway management in pediatric patients with Pierre Robin syndrome (PRS) is insufficient. Therefore, the aim of this study was to compare the efficacy of the Glidescope® Core™ with a hyperangulated blade, the C-MAC® with a nonangulated Miller blade (C-MAC® Miller) and a conventional Miller laryngoscope when used by anesthetists with limited and extensive experience in simulated Pierre Robin sequence...

BACKGROUND: Cervical spine immobilisation increases the difficulty of tracheal intubation. Many intubation devices have been evaluated in this setting, but their relative performance remains uncertain. METHODS: MEDLINE, EMBASE, and the Cochrane Library were searched to identify randomised trials comparing two or more intubation devices in adults with cervical spine immobilisation. After critical appraisal, a random-effects network meta-analysis was used to pool and compare device performance...

Videolaryngoscopes may improve intubating conditions in obese patients. A total of 110 patients with a body mass index > 35 kg∙m-2 were prospectively randomized to tracheal intubation using non-channeled Glidescope Titanium or channeled King Vision videolaryngoscope. The primary outcome was the time to tracheal intubation. Secondary outcomes included: total success rate, number of attempts, the quality of visualization, peri-procedural and post-proceduralcomplications. Time to the first effective breath was shorter with the King Vision (median; 95% CI)-36; 34-39 s vs...

PURPOSE: Intubation-associated trauma with the GlideScope is rare, but when it occurs, it is likely due to advancing the endotracheal tube (ETT) blindly between the direct view of the oropharynx and the video view of the glottis. It is also occasionally difficult to advance the ETT to the glottic aperture despite a good view of the glottis on the monitor. One technique to potentially address both issues is to introduce the ETT en bloc with the GlideScope, thus visualizing the ETT tip throughout its entire path...

BACKGROUND: Double-lumen tube (DLT) intubation is necessary for thoracic surgery and other operations with the need for lung separation. However, DLT insertion is complex and might result in airway trauma. A new videolaryngoscopy (GVL) with a thin blade might improve the intubation time and reduce complexity as well as iatrogenic airway complications compared to conventional direct laryngoscopy (DL) for DLT intubation. METHODS: A randomised, controlled trial was conducted in 70 patients undergoing elective thoracic surgery using DLT for lung separation...

BACKGROUND: The double lumen endotracheal tube (DLT) is the most widely-used device for single lung ventilation in current thoracic anesthesia practice. In recent years, the routine application of the videolaryngoscope for single lumen endotracheal intubation has increased; nevertheless there are few studies of the use of the videolaryngoscope for DLT. We wondered whether there were benefits to using the videolaryngoscope for DLT placement in patients with predicted normal airways. Therefore, this study was designed to compare the performances of the GlideScope®, the C-MAC®(D) videolaryngoscope and the Macintosh laryngoscope in DLT intubation...

Dental trauma is a common complication of tracheal intubation. As existing evidence is insufficient to validly assess the impact of different laryngoscopy techniques on the incidence of dental trauma, the force exerted onto dental structures during tracheal intubation was investigated. An intubation manikin was equipped with hidden force sensors in all maxillary incisors. Dental force was measured while 104 anaesthetists performed a series of tracheal intubations using direct laryngoscopy with a Macintosh blade, and videolaryngoscopy with a C-MAC® , or the hyperangulated GlideScope® or KingVision® laryngoscopes in both normal and difficult airway conditions...

Videolaryngoscopy (VL) may improve the success of orotracheal intubation compared with direct laryngoscopy (DL). We performed a systematic search of PubMed, Embase, and CENTRAL databases for studies comparing VL and DL for emergency orotracheal intubations outside the operating room. The primary outcome was rate of first-pass intubation, with subgroup analyses by location, device used, clinician experience, and clinical scenario. The secondary outcome was complication rates. Data are presented as [odds ratio (95% confidence intervals); P-values]...

OBJECTIVES: To test the hypothesis that laryngoscopy using the Airtraq (Prodol Limited, Viscaya, Spain) or King Vision laryngoscope (KVL) (Ambu A/S, Ballerup, Denmark) would result in a shorter time for successful double-lumen endobronchial tube (DLT) intubation by users with mixed experience than the time required using the Macintosh or GlideScope (Verathon Inc., Bothell, WA) laryngoscopes. DESIGN: A randomized, prospective, blind study. SETTING: A single university hospital...

Background: We analysed data from the Paediatric Difficult Intubation Registry examining the use of direct laryngoscopy and GlideScope® videolaryngoscopy. Methods: Data collected by a multicentre, paediatric difficult intubation registry from 1295 patients were analysed. Rates of success and complications between direct laryngoscopy and GlideScope videolaryngoscopy were analysed. Results: Initial (464/877 = 53% vs 33/828 = 4%, Z-test = 22...

PURPOSE: The GlideScope® video laryngoscope (GVL) is widely used for nasotracheal intubation in dental and facial plastic surgery. The angle of the Magill forceps is different from that of the GVL blade, which suggests that the Magill forceps are not the ideal forceps for use with the GVL. The purpose of this study was to compare the effectiveness of the Magill forceps vs vascular forceps for nasotracheal intubation using the GVL. METHODS: This study included 60 patients scheduled to undergo elective surgery requiring nasotracheal intubation...

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: 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...

BACKGROUND/AIM: Intubation must be rapidly performed with the utmost care in cervical trauma patients. We present the first comparison of GlideScope and an intubating laryngeal mask airway (ILMA) regarding insertion and intubation times, intubation success rates, mucosal damage, need for optimization maneuvers, effects on hemodynamic changes, and postoperative minor complications in a simulated cervical injury with a Philadelphia cervical collar. MATERIALS AND METHODS: Ethics committee approval and patient consent were obtained and 94 American Society of Anesthesiology physical status I or II patients were enrolled in this study...

The GlideScope (GVL; Saturn Biomedical Systems, Burnaby, British Columbia, Canada) is a rigid indirect video laryngoscope device that facilitates exposure of the larynx for placement of the endotracheal tube. This blade also reduces the requirement for anterior displacement of the tongue. A unique feature is the acutely angled blade which provides an improved glottic view. Herein, we present 2 instances of soft palate trauma, a rare oropharyngeal complication linked to GlideScope use. In the first case, the GlideScope was used for pedagogical purposes for intubation in a knee surgery...
