Macintosh direct laryngoscope has been the most widely used device for tracheal intubation. GlideScope video laryngoscope (GVL) has been recently introduced as an alternative device for performing intubation; however, its validity in emergency settings has not been thoroughly evaluated. The aim of this study was to compare Macintosh direct laryngoscope versus GVL for emergency endotracheal intu...
The Airtraq Laryngoscope is a novel intubation device which allows visualisation of the vocal cords without alignment of the oral, pharyngeal and tracheal axes. We compared the Airtraq with the Macintosh laryngoscope in simulated easy and difficult laryngoscopy. Twenty-five anaesthetists were allowed up to three attempts to intubate the trachea in each of three laryngoscopy scenarios using a La...
OBJECTIVES/HYPOTHESIS Examination of tissue structures by optical coherence tomography (OCT) has been shown to be useful on mucous membranes of the vocal folds, but so far its application to the human larynx has been limited because it is technically cumbersome and usually needs to be performed with sedation. Here a newly developed, noninvasive combined laryngoscopy and OCT procedure is describ...
To the Editor: We thank Dr. Wang, et al.[1] for the comments in our article. With regard to the first comment point, we agreed with them that Cormack‐Lehane grades 3–4 with Macintosh laryngoscope should be defined as difficult laryngoscopy. The definition of difficult airway in our paper should be difficult laryngoscopy, not difficult airway.[1] The laryngeal classification (Macintosh 3–4 blade...
BACKGROUND Sympathetic response associated with laryngoscopy and endotracheal intubation is recognised as a potential cause for a number of complications especially in hypertensive patients. Various methods have been used to attenuate these haemodynamic responses; however most of the studies are in normotensive patients. The aim of our study was to compare the effect of oral clonidine and 1/V f...
Video laryngoscopy (VL) is still a relatively novel advancement in airway management that offers many potential benefits over direct laryngoscopy. These advantages include decreased time to intubation in difficulty airways, unique opportunities in teaching as the video screen allows for real time teaching points, increased first pass success, particularly with novice operators, and decreased ce...
BACKGROUND This was a prospective randomized single-blinded clinical trial comparing the glottic views obtained during direct laryngoscopy between the 'sniffing the morning air' position and simple head extension. METHODS A sample of 378 patients, aged 18 to 75 years old with ASA physical status I or II, scheduled for elective surgery under general anesthesia with endotracheal intubation, wer...
OBJECTIVE To compare the direct and indirect (video monitor) views of the glottic opening using a new Macintosh blade that is modified to provide a video image of airway structures during laryngoscopy. DESIGN Prospective multicenter trial. SETTING 11 university-affiliated hospitals. PATIENTS 867 adults undergoing elective surgery requiring general anesthesia and tracheal intubation. INT...
Laryngoscopy is a widely used technique in anaesthesia, in which a tube is inserted into the larynx of the patient to allow controlled ventilation of the lungs during an operation. The anaesthetist uses a special instrument, the laryngoscope, to push the tongue down and expose the vocal cords and larynx. In the majority of cases a clear view can be obtained and the tube can be inserted easily. ...
OBJECTIVES/HYPOTHESIS To describe a multidisciplinary approach to the treatment of airway vascular malformations (venous or lymphatic) with direct suspension rigid laryngoscopy and direct puncture transmucosal bleomycin sclerotherapy injected under road-mapping fluoroscopic monitoring, supplemented by Dyna-computed tomography utilization. STUDY DESIGN Case series. METHODS We performed a ret...
