BACKGROUND Optiscope™ is a newly developed video stylet device. This study evaluated and compared the hemodynamic changes observed after endotracheal intubation with video stylet and after conventional laryngoscopic endotracheal intubation. METHODS Fifty-eight adult patients with American Society of Anesthesiologists (ASA) physical status class 1 or 2, undergoing general anesthesia, were rand...

BACKGROUND Manual in-line stabilization (MILS) is recommended during direct laryngoscopy and intubation in patients with known or suspected cervical spine instability. Because MILS impairs glottic visualization, the authors hypothesized that anesthesiologists would apply greater pressure during intubations with MILS than without. METHODS Nine anesthetized and pharmacologically paralyzed patie...

Properly functioning equipment is critical during direct laryngoscopy for endotracheal intubation. When the light source on a laryngoscope fails, proper visualization of the glottic opening is then extremely difficult in the then dark vault of the oropharynx, and alternative endotracheal intubation techniques must often be employed in a time sensitive manor. Laryngoscopic light source failure m...

this study involved 154 anesthetized patients requiring endotracheal intubation, in whom the epiglottis was visible but not lifted, which restricted the view of the glottis. a simple stylet was used to lift the epiglottis, thus improving the view of the glottis with the glide scope®, allowing tracheal tubes to be inserted into the patients. the stylet easily resolved the difficulty of lifting t...

BACKGROUND McGrath MAC video laryngoscope offers excellent laryngosopic views and increases the success rate of orotracheal intubation in some cases. The aim of this study was to determine the usefulness of McGrath MAC for routine nasotracheal intubation by comparing McGrath MAC with Airway scope and Macintosh laryngoscope. METHODS A total of 60 adult patients with ASA physical status class 1...

OBJECTIVE Training students on simulators before allowing their direct contact with patients is well accepted. There is no clinical or manikin-based simulation study in the literature comparing tracheal intubation with Airtraq, laryngeal mask airway (LMA) CTrach and Macintosh laryngoscopes performed by medical students having no prior intubation experience. METHODS After obtaining written inf...

Visualization of the larynx by direct or indirect means is referred to as laryngoscopy and is the principal aim during airway management for passage of a tracheal tube. This paper presents a brief background regarding the development and practice of laryngoscopy and examines the equipment and techniques for both direct and indirect methods. Patient evaluation during the airway examination is di...

Background: This study assesses the effectiveness of the GlideScope Videolaryngoscope (GS) in comparison with the Macintosh laryngoscope in a simulated difficult airway with blood in the airway and restricted range of motion of the neck. 39 participants experienced with the GS and the Macintosh laryngoscope were used. Methods: This analysis is a prospective, randomized, crossover study. Our stu...
