BACKGROUND AND OBJECTIVE: Early-stage diagnosis of laryngeal cancer is of primary importance to reduce patient morbidity. Narrow-band imaging (NBI) endoscopy is commonly used for screening purposes, reducing the risks linked to a biopsy but at the cost of some drawbacks, such as large amount of data to review to make the diagnosis. The purpose of this paper is to present a strategy to perform automatic selection of informative endoscopic video frames, which can reduce the amount of data to process and potentially increase diagnosis performance...

We herein report anesthetic management during aortic valve replacement for aortic valve regurgitation in a patient with adult mucopolysaccharidosis type II (MPS type 2) (Hunter syndrome). This disorder is rare and related to the accumulation of a mucopolysaccharide in lysosomes. It affects various organs, including the airways, heart, and central nerves. In children with MPS type 2, the risk of airway obstruction during anesthesia/sedation is high, and the degree of difficulty increases with aging. The patient described herein was a 33-year-old male without mental retardation...

Background: Tracheal intubation using the 2nd-generation video laryngoscope sometimes cannot be performed easily because there is no functional endotracheal tube (ETT) guide. Therefore, a rigid stylet is often required during tracheal intubation. The Endotrol® tracheal tube (Endotrol) is a single use ETT that whole tube can be bent and slide easily into the trachea. We studied the intubation ease of a combination of an Endtrol and the McGrath® video laryngoscope (McGrath), which is one of the 2nd-generation video laryngoscopes...

Mask ventilation, the first step in airway management, is a rescue technique when endotracheal intubation fails. Therefore, ordinary airway management for the induction of general anesthesia cannot be conducted in the situation of difficult mask ventilation (DMV). Here, we report a case of awake intubation in a patient with a huge orocutaneous fistula. A 58-year-old woman was scheduled to undergo a wide excision, reconstruction with a reconstruction plate, and supraomohyoid neck dissection on the left side and an anterolateral thigh flap due to a huge orocutaneous fistula that occurred after a previous mandibulectomy and flap surgery...

The major complications of paediatric airway management are uncommon, but the outcomes are often severe. Over the last decade, additions and advancements in the devices and technology have significantly improved our ability to manage difficult paediatric airways safely. Videolaryngoscopy involves the use of video and optical technology to facilitate indirect visualisation of the larynx during intubation and has been seen as an evolutionary step in intubation technology. Over the past few years, video laryngoscopes have been receiving plenty of attention as new airway devices for use in paediatric patients...
