INTRODUCTION: Airway management and tracheal intubation are routinely performed in paediatric anaesthesia and yet are associated with preventable adverse events. The McGrath(®) MAC is a video laryngoscope with a curved blade similar to the Macintosh blade, which has not been previously described in first intention paediatric tracheal intubation. We aimed to compare direct laryngoscopy to the McGrath(®) MAC video laryngoscope among novice laryngoscopists. METHODS: Six paediatric anaesthesia residents with novice skills in paediatric laryngoscopy were randomly assigned to perform tracheal intubation using either direct Macintosh laryngoscopy (DL) or the McGrath(®) MAC video laryngoscope (MM) as the first attempted device in children weighing between 10 and 20kg without difficult intubation...

There is a need for a validated endotracheal intubation trainer that has variable difficulty settings for the training and assessment of medical practitioners. In this study three anatomical modifications were retrofitted to a commercial manikin and then validated. These modifications included restricted movements of the mandible as well as changes to the upper incisors. A total of 130 participants comprising specialists, trainees and medical students volunteered for this study. Validity was tested using randomised between-groups comparison of the time taken to intubate the manikin on all settings...

INTRODUCTION: In the difficult airway, the intubation skills are critically important. In selected cases, particularly in airway edema, laryngeal or tongue edema, endotracheal intubation can turn out very difficult, and repeated attempts may even worsen the airway edema, causing trauma and bleeding, and finally leading to complete airway obstruction and inability to ventilate the patient. AIM OF THE STUDY: The aim of the study was to compare the efficacy of endotracheal intubation performed by novice physicians using a standard Macintosh laryngoscope and an Intubrite videolaryngoscope...

PURPOSE: Skill acquisition in direct laryngoscopy (DL) and tracheal intubation is complex. This pilot study aims to assess feasibility and determine sample size for a subsequent trial comparing DL instruction using a Macintosh-style video laryngoscope (MacVL), with and without video recordings, with conventional DL instruction. METHODS: Medical students with no prior laryngoscopy experience were recruited during their two-week anesthesia rotation. During the first (TRAINING) week, students were randomized into three groups: Control (Macintosh direct laryngoscope), VL-1 (MacVL with real-time feedback), and VL-2 (MacVL with real-time feedback plus video recordings of laryngoscopies)...

BACKGROUND: Dacryocystorhinostomy (DCR) can be performed via an external or endoscopic approach. The use of ultrasonic or piezosurgery has been well described for endoscopic DCRs but is lacking for external DCRs. This study presents a case series of external DCRs performed using piezosurgery evaluating results and complications. METHODS: Prospective, consecutive case series of patients undergoing primary external DCR for lacrimal drainage insufficiency. A standard external DCR technique was used using 1 of 2 piezosurgery systems for all bone incision...

We hypothesized that the McGRATH MAC would decrease the time of intubation compared to C-MAC for novices. Thirty-nine medical students who had used the Macintosh blade to intubate a manikin fewer than 3 times were recruited. The participants performed sequential intubations on the manikin in two simulated settings that included a normal airway and a difficult airway (tongue edema). The intubation time, success rate of intubation, Cormack-Lehane grade at laryngoscopy, and difficulty using the device were recorded...

In addition to being effective and easy to learn how to use, the ideal laryngoscope should be associated with minimal reduction in skill performance during gaps in practice over time. We compared the time taken to intubate the trachea of a manikin by novice medical students immediately after training, and then after 1 month, with no intervening practice. We designed a two-period, four-group, randomised, cross-over trial to compare the Macintosh, Venner(™) A.P. Advance(™) with difficult airway blade, C-MAC(®) with D-Blade and Airtraq(®) with wireless video-viewer...

Despite the lack of uniformity and the need of further investigation, video laryngoscopy continues to gain popularity both inside and outside the operating room. It has quickly become a first line strategy for potential and/or encountered difficult intubation. It is well established that video laryngoscope improves laryngeal view as compared with direct laryngoscopy in patients with suspected difficult intubation and simulated difficult airway scenarios. For novices and experienced anesthesiologists alike, video laryngoscopy is easy to use and the skills involved are easy to master...
