OBJECTIVES: Transesophageal echocardiography (TEE) probe insertion with the conventional blind insertion technique may be difficult in anesthetized and intubated patients. The use of a videolaryngoscope may facilitate the insertion of the TEE probe. The aim of this study was to compare the conventional technique with the use of the McGrath MAC videolaryngoscope for TEE probe insertion in terms of success rate, duration of insertion, and complications in patients undergoing cardiovascular surgery...

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...

BACKGROUND: Videolaryngoscopes are aggressively marketed, but independent evaluation in difficult airways is scarce. This multicentre, prospective randomized controlled trial evaluates six videolaryngoscopes in patients with a simulated difficult airway. METHODS: With ethics committee approval and written informed consent, 12 senior anaesthetists intubated the trachea of 720 patients. A cervical collar limited mouth opening and neck movement, making intubation difficult...

BACKGROUND: The McGrath MAC video laryngoscope can improve visualisation of the glottis compared with the Macintosh direct laryngoscope. However, good visualisation of the glottis does not guarantee rapid or successful intubation because of difficulty in handling the McGrath device. OBJECTIVE: We evaluated the effect of head elevation, aligning the positions of the external auditory meatus and sternal notch in the horizontal plane, on visualisation of the glottis and handling of the McGrath laryngoscope in paediatric patients...

Videolaryngoscopy is often reserved for 'anticipated' difficult airways, but thereby can result in a higher overall rate of complications. We observed 65 anaesthetists, 67 residents in anaesthesia, 56 paramedics and 65 medical students, intubating the trachea of a standardised manikin model with a normal airway using seven devices: Macintosh classic laryngoscope, Airtraq(®) , Storz C-MAC(®) , Coopdech VLP-100(®) , Storz C-MAC D-Blade(®) , GlideScope Cobalt(®) , McGrath Series5(®) and Pentax AWS(®) ) in random order...

We compared the performance of the McGrath® Series 5 videolaryngoscope with the Macintosh laryngoscope in 49 patients without suspected cervical spine pathology, whose cervical spine was immobilised using a semi-rigid collar. The primary outcome was the view obtained at laryngoscopy. Secondary outcomes included time to tracheal intubation, rates of successful intubation and incidence of complications. In all patients, the view was better (92%) or the same (8%) in the McGrath group versus the Macintosh group (p < 0...

Difficult and failed intubations account for the major causes of morbidity and mortality in current anesthetic practice. Several devices including McGrath Series 3 videolaryngoscope are available which may facilitate tracheal intubation by improving view of the larynx compared with Macintosh blade laryngoscopy. But no studies demonstrate whether McGrath Series 3 performs better than Macintosh laryngoscope in normal airway intubations by inexperienced anesthetists so far. We therefore designed this randomized controlled study to compare McGrath with Macintosh in routine tracheal intubation performed by inexperienced anesthetists...

INTRODUCTION: Critically ill patients with acute respiratory, neurological or cardiovascular failure requiring invasive mechanical ventilation are at high risk of difficult intubation and have organ dysfunctions associated with complications of intubation and anaesthesia such as hypotension and hypoxaemia. The complication rate increases with the number of intubation attempts. Videolaryngoscopy improves elective endotracheal intubation. McGRATH MAC is the lightest videolaryngoscope and the most similar to the Macintosh laryngoscope...

PURPOSE: The purpose of this study is to determine the educational suitability of the video-laryngoscope in teaching endotracheal intubation to students. METHODS: Medical students participated in a course on the use of a Macintosh direct laryngoscope and McGrath MAC videolaryngoscope for intubation. The course comprised a 1-hour lecture and 30 minutes of practice on a manikin. After the course, in each of the three simulated patient scenarios-normal airway, cervical spine fixation, and tongue edema-time to intubate, success rate, and chance of complications were measured...

BACKGROUND: Videolaryngoscopes may not be useful in the presence of hematemesis or vomitus. We compared the utility of the Macintosh laryngoscope (McL), which is a direct laryngoscope, with that of the Pentax-AWS Airwayscope (AWS) and McGRATH MAC (McGRATH), which are videolaryngoscopes, in simulated hematemesis and vomitus settings. METHODS: Seventeen anesthesiologists with more than 1 year of experience performed tracheal intubation on an adult manikin using McL, AWS, and McGRATH under normal, hematemesis, and vomitus simulations...

A 67-year-old woman suffering from hoarseness or dysphagia was diagnosed with motor neuron disease. She was scheduled for laparoscopic cholecystectomy under general anesthesia for suspected gallbladder cancer. She was concerned about the exacerbation of her hoarseness or dysphagia from tracheal intubation. We therefore decided to perform airway management by using supraglottic device air-Q blocker, through which a gastric tube could be inserted. We first passed the gastric tube through the outer blocker hole and inserted it into the esophagus using Magill forceps...

Here we report successful rapid-sequence inubation with the McGRATH MAC videolaryngscope (McGRATH) in the face to face sitting position for a patient with severe ileus and restricted mouse opening. A 46-year-old woman with advanced bladder cancer had developed ileus. Ileus tube and octreotide did not relieve her symptoms, and emergency colostomy was planned. Due to the invasion of cancer to the spine and interior of the pelvis, she could not keep supine position and always kept sitting position. We decided to perform rapid-sequence intubation in the sitting position...

We compared the McGrath MAC(®) videolaryngoscope when used as both a direct and an indirect laryngoscope with a standard Macintosh laryngoscope in patients without predictors of a difficult tracheal intubation. We found higher median Intubation Difficulty Scores with the McGrath MAC as a direct laryngoscope, 1 (0-3 [0-5]) than when using it as an indirect videolaryngoscope, 0 (0-1 [0-5]) or when using the Macintosh laryngoscope, 0 (0-1 [0-5]), p = 0.04. This was mirrored in the subjective user reporting, scored out of 10, of difficulty for each method 3...

Currently, there are plenty of videolaryngoscopes that appear on the market. They have different specifications. Some of these features favor the fact that they are more suited for educational purposes of future operators and others can be characterized with an excellent clinical use. In this study we compared four types of videolaryngoscopes. The aim of the study was to compare the technical specifications of the above-mentioned devices for usefulness in clinical practice and correlate these parameters with the subjective evaluation of these videolaryngoscopes usage performed in practice by an experienced medical staff...

We compared the McGrath® Series 5 videolaryngoscope with the Macintosh laryngoscope for double-lumen tracheal tube placement in patients with a predicted good glottic view on assessment of the airway. An initial laryngoscopy was performed using the Macintosh laryngoscope; 96 patients with Cormack and Lehane grade-1 or -2a views were randomly assigned to undergo intubation using either the McGrath or Macintosh device. Compared with the Macintosh laryngoscope, the McGrath videolaryngoscope provided more Cormack and Lehane grade-1 views (47 (97...
