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...

SUMMARY Tracheal intubation using direct laryngoscopy has a high failure rate when performed by untrained medical personnel. This study compares tracheal intubation following direct laryngoscopy by inexperienced medical students when initially trained by using either the GlideScope, a video assisted laryngoscope, or a rigid (Macintosh) laryngoscope. Forty-two medical students with no previous e...

conclusions our study revealed weak correlation between pe/e-vc and cormack-lehane grade, with 87% sensitivity and 30% specificity. therefore, we concluded that sonographic measurement criteria are not accurate in airway evaluations before anesthesia. results it was observed that correlations between the pre-epiglottic space (pe) and cormack-lehane grades i, ii, and iii were weak. correlations ...

BACKGROUND Nasotracheal intubation typically comprises three distinct stages: (i) nasopharyngeal intubation; (ii) direct laryngoscopy to identify the vocal cords; and (iii) the passage of the tracheal tube into the trachea. The aim of this study was to identify and compare the cardiovascular responses associated with each of these stages. METHODS Seventy-five ASA I or II patients, aged 16-65 ...

BACKGROUND Tracheal intubation with conventional laryngoscopy requires many trials until beginners are sufficiently skilled in intubating patients safely. To facilitate intubation, the authors used retrograde light-guided laryngoscopy (RLGL) and compared its feasibility with conventional direct laryngoscopy (DL). METHODS Twenty operators participated in a prospective, randomized, open-label, ...

a varieties of medications have been suggested to prevent hemodynamic instabilities following laryngoscopy and endotracheal intubation. this study was conducted to determine the beneficial effects of gabapentin on preventing hemodynamic instabilities associated with intubation in patients who were a candidate for coronary artery bypass surgery (cabg). this double blinded randomized, parallel gr...

BACKGROUND The Berci-Kaplan video laryngoscope was developed to improve the visualization of the glottis and ease tracheal intubation. Whether this technique is also effective in patients with an expected difficult intubation is unclear. We have prospectively evaluated the conditions and success rate of tracheal intubation in patients with a Mallampati score of III or IV. METHODS Two hundred ...
