Introduction: Ludwig's angina (LA) is a life-threatening infection that can affect the floor of the mouth and neck, potentially causing serious airway obstruction. In such cases, rescue airway management and oxygenation can be challenging due to swelling of the mouth floor, trismus, and limited mouth opening. The aim of this study was to assess the efficacy of the Trachway video-stylet (VS) and Pentax AWS hyperangulated videolaryngoscope with channel (HAVL-C) compared to the standard geometric video-laryngoscope (SGVL, Macintosh 3, Trachway) in simulating Ludwig's angina with cadavers.

Background: Pentax Airway Scope (AWS) is a recently developed videolaryngoscope for use in both normal and difficult airways, yet its use in paediatric patients has not been established. The purpose of this study was to evaluate the efficacy of the Pentax AWS regarding intubation time, laryngeal view and ease of intubation in paediatric patients with normal airway, compared to Macintosh laryngoscope.

Method: A total of 136 paediatric patients aged 1-10 with American Society of Anaesthesiologists physical status I or II undergoing general anaesthesia were randomly allocated into two groups: Macintosh laryngoscope (n = 68) and Pentax Airway Scope (n = 68).

Objective To determine whether intubation education using the Pentax Airway Scope (AWS) in normal airways is more useful than direct laryngoscopy (Macintosh laryngoscope) in novice personnel. Methods Eleven intern doctors without intubation experience performed 60 sequential intubations with each device on a manikin and 10 sequential intubations in adult patients. The time required for successful intubation, percentage of glottic opening (POGO) score, number of intubation attempts, and number of dental injuries were analyzed for each intubation technique.

Background: Tracheal intubation during cardiopulmonary resuscitation is a high-risk procedure. The aim of this study was to compare efficacy of intubation with the Pentax AWS, Airtraq, and McCoy laryngoscopes in patients with cervical spine immobilization during resuscitation in a randomized, controlled simulation trial.

Methods: We compared times to intubation, success rate, Cormack and Lehane grading, and ease of intubation when using Pentax AWS, Airtraq, and McCoy in randomized order.
