BACKGROUND Video-laryngoscopes have gained popularity in the recent years and have shown definite advantages over the conventional Macintosh direct laryngoscopes. However, there is still insufficient evidence comparing the C-MAC with the Macintosh for patients during manual inline stabilization (MILS). METHODS This prospective, randomized, single blind study was carried out to compare trachea...

The recent discoveries of algorithms for three dimensional reconstructions from projections (Cormack, 1963; De Rosier & Klug, 1968; Crowther, De Rosier & Klug, 1970; Vainshtein, 1970; Gordon, Bender & Herman, 1970; Berry & Gibbs, 1970; Ramachandran & Lakshminarayanan, 1971; Goitein, 1971; Matulka & Collins, 1971; Gilbert, 1972; Cormack, 1973; Sweeney & Vest, 1973; Smith,.Peters & Bates, 1973) a...

The laryngoscope should displace oral soft tissues forward out of the operator's vision. Therefore, the space in front of the view may be critical for determining the laryngoscopic view. The aim was to investigate the difference in the previsional space during difficult versus easy laryngoscopy (EL).Under general anesthesia, digital photographs of the lateral view of the head and neck were take...

The authors extend the classical Cormack–Jolly–Seber mark-recapture model to account for both temporal and spatial movement through a series of markers (e.g., dams). Survival rates are modeled as a function of (possibly) unobserved travel times. Because of the complex nature of the likelihood, they use a Bayesian approach based on the complete data likelihood, and integrate the posterior throug...

Copyright c Korean Society of Anesthesiologists, 2009 Background: Unanticipated difficulties during tracheal intubation are related to perioperative morbidity and mortality, but the success of direct laryngoscopic intubation depends largely on clinician’s experience and the upper airway anatomy. The lightwand was introduced as alternative intubation technique, but the indicators of difficult li...

We studied prospectively the reliability of clinical methods, end-tidal carbon dioxide (ETCO(2)) detection, and the esophageal detector device (EDD) for verifying tracheal intubation in 137 adult patients in the emergency department. Immediately after intubation, the tracheal tube position was tested by the EDD and ETCO(2) monitor, followed by auscultation of the chest. The views obtained at la...

BACKGROUND Failure to maintain a patent airway can result in brain damage or death. In patients with mandibular prognathism or retrognathism, intubation is generally thought to be difficult. We determined the degree of difficulty of airway management in patients with mandibular deformity using anatomic criteria to define and grade difficulty of endotracheal intubation with direct laryngoscopy. ...
