Abstract:

Introduction: Aerosol box is a usefull tools to prevent aerosol and droplet contaminations during laryngoscopy and intubation in COVID-19 pandemic. Video laryngoscope is recommended during this era to increase the operator and patient’s distance during the procedure. However, many anesthesiologists still use direct laryngoscopes due to their availability and familiarity. This study aims to compare endotracheal tube intubation with video laryngoscope compared to direct laryngoscope in elective surgery patients. Methods: This study was a quasi-experimental study.

Abstract:

IntroductionThe direct laryngoscopy technique using a Macintosh blade is the first choice globally for most anaesthetists. In case of an unanticipated difficult airway, the complication rate increases with the number of intubation attempts. Recently, McGrath MAC (McGrath) video laryngoscopy has become a widely accepted method for securing an airway by tracheal intubation because it allows the visualisation of the glottis without a direct line of sight. Several studies and case reports have highlighted the benefit of the video laryngoscope in the visualisation of the glottis and found it to be

Abstract:

The rare and potentially fatal complication of asystole during direct laryngoscopy is linked to direct vagal stimulation. This case describes asystole in an 85-year-old female who underwent suspension microlaryngoscopy with tracheal dilation for subglottic stenosis. Quick recognition of this rare event with immediate cessation of laryngoscopy resulted in the return of normal sinus rhythm. This incident emphasizes the implications of continued vigilance during laryngoscopy and the importance of communication between the anesthesia and surgical staff to identify and treat this rare complication.

Background: Iatrogenic dental injury is the most common complication of conventional laryngoscopy during orotracheal intubation.

The aim of this pilot study was to introduce and test a novel, reusable low-budget device not only providing contactless dental protection during direct laryngoscopy for endotracheal intubation, but also enabling, in contrast to established tooth protectors, active levering with conventional laryngoscopes for easier visualization of the glottis.

Abstract:

Uvular injuries are uncommon after general anesthesia and can result from direct trauma to the posterior part of the soft palate or compression and restriction of blood flow to the uvula caused by the inadvertent placement of the airway or suction devices in the oral cavity. There have been cases of inflammation and ulceration occurring in the midline oropharyngeal structures such as the uvula after general anesthesia with a tube or laryngeal mask airway, even in the absence of direct trauma or infection, presumably due to compression ischemia.

At our institution, the otolaryngology department has incorporated the use of the endotracheal tube cuff-leak test and bedside direct laryngoscopy to aid in timing for extubation of angioedema patients. Prospective data collection of patients presenting to the emergency department with angioedema was performed. Of 76 patients with angioedema, 9 required fiberoptic intubation.

Abstract:

Minimally invasive surfactant therapy (MIST) has emerged as a preferred method of surfactant delivery. Pioneers of this technique have described the use of direct laryngoscopy (DL) for MIST. With the increasing application of video laryngoscopy (VL) for neonatal airway management, it is speculated that MIST techniques can be adapted for use with VL. Objective: To compare procedural success, operator ease of use, and complication of MIST using VL vs. MIST using DL. Methods: This was a retrospective, observational cohort study conducted at a tertiary-level neonatal intensive care unit after obta

Abstract:

Introduction: Intubation is one of the highest-risk procedures performed in the ED. Few Canadian centres monitor intubation frequency, indications, methods used, success, and/or complication rates. An airway registry that tracks patient outcomes and variation in practice would be a valuable quality improvement (QI) tool. We describe the development of the BC-Airway Registry for Emergencies (BCARE) network, an emergency intubation database at two tertiary-care and one community hospital.

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.

Steven-Johnson syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are severe drug allergic reactions characterized by skin and mucosal membrane detachments. Most of the literature focuses only on the skin and ocular mucosal damage, but more severe and life-threatening mucosal damage may actually occur in the respiratory tract. This airway involvement may cause an acute complication, e.g. acute respiratory failure, and chronic complications, e.g. bronchiolitis organizing pneumonia, bronchiectasis, and restrictive bronchiolitis.

IntroductionAmong critically ill patients undergoing orotracheal intubation in the emergency department (ED) or intensive care unit (ICU), failure to visualise the vocal cords and intubate the trachea on the first attempt is associated with an increased risk of complications.

Abstract:

Masseter spasm after induction of anaesthesia can be generally defined as a marked difficulty in manual mouth opening that interferes and impedes direct laryngoscopy and tracheal intubation without the presence of temporomandibular joint dysfunction. Several factors have been implicated in the literatures responsible for causing masseter spasm including use of non-depolarizing muscle relaxants, selective serotonin reuptake inhibitor and anxiety. Our case is the first to report masseter spasms with the use of Cis-atracurium in a patient on antidepressant depressant treatment with sertraline and

Dysphagia after anterior cervical discectomy and fusion (ACDF) is common, with a prevalence ranging between 28% and 57% of cases.

A review of literature reveals a paucity of case reports detailing work-up and successful management options.
