BACKGROUND: During McGrath videolaryngoscope (VL) intubation, a styletted endotracheal tube maintaining an upward distal tip angle is recommended by some manufacturers. However, a styletted endotracheal tube can elicit rare but potentially serious complications. The purpose of this study was to demonstrate that a nonstyletted tube with exaggerated curvature would be noninferior to a styletted tube for orotracheal intubation using McGrath VL in patients with expected normal airway, by comparing the time to intubation and ease of intubation...

A predicted difficult airway is sometimes considered a contra-indication to rapid sequence induction of general anaesthesia, even in an urgent case such as a category-1 caesarean section for fetal distress. However, formally assessing the risk is difficult because of the rarity and urgency of such cases. We have used decision analysis to quantify the time taken to establish anaesthesia, and probability of failure, of three possible anaesthetic methods, based on a systematic review of the literature. We considered rapid sequence induction of general anaesthesia with videolaryngoscopy, awake fibreoptic intubation and rapid spinal anaesthesia...

BACKGROUND: Noninvasive ventilation (NIV) titration may be difficult when dynamic airway obstruction episodes persist, even with high expiratory positive airway pressure (EPAP). We aimed to determine the usefulness of videolaryngoscopy during NIV for identifying mechanisms and sites of obstruction and for providing a guide for their resolution in difficult-to-titrate subjects. METHODS: When obstructions during NIV were present in the built-in software, EPAP was raised to 12cm H2O...

Lingual tonsils are lymphatic tissues located at the base of the tongue that may hypertrophy causing difficulty and sometimes inability to ventilate or intubate during anesthesia. Routine airway assessment fails to diagnose lingual tonsil hypertrophy. There is limited experience with use of videolaryngoscopy in cases of lingual tonsil hypertrophy. We present a case of difficult airway due to unanticipated lingual tonsil hypertrophy successfully managed by atypical video laryngoscope positioning.

BACKGROUND: Successful tracheal intubation during general anaesthesia traditionally requires a line of sight to the larynx attained by positioning the head and neck and using a laryngoscope to retract the tongue and soft tissues of the floor of the mouth. Difficulties with intubation commonly arise, and alternative laryngoscopes that use digital and/or fibreoptic technology have been designed to improve visibility when airway difficulty is predicted or encountered. Among these devices, a rigid videolaryngoscope (VLS) uses a blade to retract the soft tissues and transmits a lighted video image to a screen...

INTRODUCTION: The use of videolaryngoscopy continues to play a larger role in the approach to patients with airway pathology. Looking specifically at patients with potential difficulty in ventilation and intubation due to thyroid goiter, video laryngoscopy may provide a faster and easier technique to secure the airway compared to direct laryngoscopy. PRESENTATION OF CASE: In the case we will present to you, a 60-year-old female with a large goiter presented to a community hospital emergency room where she was found to be in respiratory distress with increased work of breathing...

BACKGROUND: Airway management in the emergency room can be challenging when patients suffer from life-threatening conditions. Mental stress, ignorance of the patient's medical history, potential cervical injury or immobilisation and the presence of vomit and/or blood may also contribute to a difficult airway. Videolaryngoscopes have been introduced into clinical practice to visualise the airway and ultimately increase the success rate of airway management. OBJECTIVE: The aim of this study was to test the hypothesis that the C-MAC videolaryngoscope improves first-attempt intubation success rate compared with direct laryngoscopy in patients undergoing emergency rapid sequence intubation in the emergency room setting...

BACKGROUND: Reinke's edema is a benign lesion of the vocal folds that affects chronic smokers, especially women. The voice becomes hoarse and virilized, and the treatment is microsurgery. However, even after surgery and smoking cessation, many patients remain with a deep and hoarse voice. OBJECTIVES: The aim of the present study was to compare pre- and postoperative acoustic and perceptual-auditory vocal analyses of women with Reinke's edema and of women in the control group, who were non-smokers...

OBJECTIVE: Currently, various tools have been introduced for the assessment of vocal fold vibration: laryngeal videolaryngoscopy (LV), videokymography (VKG), high speed videoendoscopy (HSV), digital videokymography (DKG), and 2D scanning videokymography (2D VKG). Among these, the authors have recently designed a dual modality examination system using LV and 2D VKG for more detailed information regarding the vibrations of the vocal folds. The clinical availability of this hybrid system offers medical imaging departments a range of potential advantages in the evaluation of vocal fold vibration...

OBJECTIVES: To compare clinicians' ratings of videolaryngoscopy (VLS) and high-speed videoendoscopy (HSV) and assess confidence of ratings with VLS and HSV in patients with supraglottic phonation. METHODS: The VLS and HSV video samples were taken from 11 adolescents post airway reconstruction who use supraglottic tissues for voice. The 22 recordings were randomized and presented to 4 clinicians: 2 speech-language pathologists and 2 pediatric otolaryngologists. Additionally, a 5-point Likert scale was used to rate level of confidence of ratings...

OBJECTIVES: Opportunities to learn advanced airway management skills on pediatric patients in the emergency department are limited. Current strategies have focused largely on traditional didactics coupled with procedural skills training using simulation. However, these approaches are limited in their exposure to anatomic variation and realism. Here, we describe the development and assessment of an advanced airway curriculum that integrates videolaryngoscopic recordings obtained during actual patient intubations into a series of interactive educational sessions...

OBJECTIVES: Reports of patient injuries associated with videolaryngoscopy are increasing in the literature. There are a wide variety of opinions regarding both safe use of the device and patient care following aerodigestive tract injury. We have seen an increase in videolaryngoscopy-associated injuries in recent years at our institution. Because of this, we wanted to determine if video-assisted laryngoscopy presents a greater risk of injury compared with direct laryngoscopy. Furthermore, we wanted to determine if there were patient and/or surgical factors that could contribute to patient injuries following videolaryngoscopy...

BACKGROUND: Tracheal intubation using acute-angle videolaryngoscopy achieves high success rates, but is not without difficulty. We aimed to determine predictors of 'difficult videolaryngoscopy'. METHODS: We performed a secondary analysis of a data set (n=1100) gathered from a multicentre prospective randomized controlled trial of patients for whom difficult direct laryngoscopy was anticipated and who were intubated with one of two videolaryngoscopy devices (GlideScope(®) or C-MAC(®) with D-blade)...

BACKGROUND: The Scandinavian society of anaesthesiology and intensive care medicine task force on pre-hospital airway management was asked to formulate recommendations following standards for trustworthy clinical practice guidelines. METHODS: The literature was systematically reviewed and the grading of recommendations assessment, development and evaluation (GRADE) system was applied to move from evidence to recommendations. RESULTS: We recommend that all emergency medical service (EMS) providers consider to: apply basic airway manoeuvres and airway adjuncts (good practice recommendation); turn unconscious non-trauma patients into the recovery position when advanced airway management is unavailable (good practice recommendation); turn unconscious trauma patients to the lateral trauma position while maintaining spinal alignment when advanced airway management is unavailable [strong recommendation, low quality of evidence (QoE)]...
