Emergency airway management in children is generally considered to be challenging, and endotracheal intubation requires a high level of personal skills and experience. Immobilization of the cervical spine is indicated in all patients with the risk of any cervical spine injury but significantly aggravates endotracheal intubation. The best airway device in this setting has not been established yet, although the use of videolaryngoscopes is generally promising. Seventy-five moderately experienced paramedics of the Emergency Medical Service of Poland performed endotracheal intubations in a pediatric manikin in three airway scenarios: (A) normal airway, (B) manual in-line cervical immobilization, and (C) cervical immobilization using a Patriot cervical extrication collar and using two airway techniques: (1) McGrath videolaryngoscope and (2) Macintosh blade in a randomized sequence...

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...

PURPOSE: Videolaryngoscopes may not be useful in the presence of vomitus due to blurred images on the monitor. The objective of our study is to compare the utility of gum-elastic bougie (GEB) application for tracheal intubation with the Macintosh laryngoscope (McL), which is a direct laryngoscope, with that of the Pentax-AWS Airwayscope® (AWS) and McGRATH® MAC (McGRATH) in simulated vomitus settings. METHODS: Sixteen novice doctors performed tracheal intubation on an adult manikin using McL, AWS, and McGRATH with or without GEB under normal and vomitus simulations...

Videolaryngoscopes improve the view of the entry to the larynx in morbidly obese patients. Super obesity is one of the risk factors for difficult mask ventilation as well as difficult intubation. Super obese patients should be intubated awake either with a fiber-optic scope or with a videolaryngoscope. The glottic view during video-intubation in super obese patients using different devices was compared. The McGrath MAC (MGM) was used in all patients and then compared to the King Vision (KV) in three patients, the APA videolaryngoscope in two patients and the Airtraq Avant with a video camera in four patients...

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...

We experienced a case of successful nasotracheal intubation using the X-Blade of the McGrath MAC in a 28-year-old woman with a 2.5-cm mouth opening. She had no teeth on the right side, her neck movement was limited, her mandibular protrusion was grade C, and her Mallampati could not be evaluated. Her tongue was fixed to the left wall during a previous surgery. We evaluated the awake glottic view using the McGrath MAC X-Blade and topical oral anesthesia. We obtained a Cormack-Lehane grade II view and then decided to administer general anesthesia...

BACKGROUND: Pre-hospital endotracheal intubation is challenging and repeated endotracheal intubation is associated with increased morbidity and mortality. We investigated whether the introduction of the McGrath MAC video laryngoscope as the primary device for pre-hospital endotracheal intubation could improve first-pass success rate in our anaesthesiologist-staffed pre-hospital critical care services. We also investigated the incidence of failed pre-hospital endotracheal intubation, the use of airway adjuncts and back-up devices and problems encountered using the McGrath MAC video laryngoscope...

We report the successful anesthetic management of video-assisted left upper lobectomy in a patient with ischemic heart disease using an intra-aortic balloon pump (IABP). An 81-year-old man with severe ischemic heart disease was scheduled for partial lobectomy for suspected lung cancer under general anesthesia. Although he had severe ischemic heart disease, coronary intervention such as percutaneous cardiac intervention or coronary artery bypass grafting was impossible due to severe coronary stenosis. IABP was instituted through the femoral artery before inducing anesthesia...

A patient with Klippel-Feil syndrome had difficulties in inserting and placing an endotracheal tube under general anesthesia. Klippel-Feil syndrome, characterized by cervical vertebral fusion, scoliosis and endocardiosis, is a rare disease. Anesthesiologists should pay attention to management of anesthesia in airway troubles. A 53-year-old woman diagnosed with Klippel-Feil syndrome was scheduled for general anesthesia with intubation. We tried to insert an endotracheal tube using McGRATH MAC, but it was difficult to insert and place the tube...

BACKGROUND: Hypertension often occurs after tracheal intubation using a Macintosh laryngoscope and may lead to rare but serious complications. The Macintosh laryngoscope may increase the incidence of hypertension because it requires forced alignment of the oral and pharyngeal axes in order to view the glottis. In contrast, the McGRATH MAC video laryngoscope does not require this manipulation. The objective of this study was to evaluate the incidence of hypertension after tracheal intubation using a McGRATH laryngoscope compared with a Macintosh laryngoscope...

INTRODUCTION: The performance of laryngoscopes that have been developed for difficult airways can vary widely. The aim of the study was to compare Macintosh, McCoy, McGrath MAC, and C-MAC laryngoscopes in cervical immobilization and tongue edema scenarios in a mannequin, primarily to evaluate the time to intubation. METHODS: In this randomized crossover study, 41 anesthesiology residents used 4 laryngoscopes in a mannequin (SimMan 3G) in 2 different scenarios. Intubation time (insertion of the blade between the teeth, to placement of the endotracheal tube into the trachea) longer than 120 seconds or inability to successfully place the endotracheal tube into the trachea after 5 or more attempts was defined as intubation failure...
