This study aims to compare the hemodynamic responses to endotracheal intubation performed with direct and video laryngoscope in patients scheduled for cardiac surgery and to assess the airway and laryngoscopic characteristics. One hundred ten patients were equally allocated to either direct Macintosh laryngoscope (n = 55) or indirect Macintosh C-MAC video laryngoscope (n = 55). Systolic, diasto...

BACKGROUND AND OBJECTIVES The concern of facing difficult airways brought the need of developing predictive testing for difficult intubation. Those tests were developed primarily for adult populations. In pediatric patients studies always focus on patients with congenital malformation, polytraumatized, and newborns. The objective of the present study was to determine the applicability of the pr...

PURPOSE To evaluate a comprehensive scoring system which combines clinical manifestations of Pierre Robin Sequence (PRS) including severity of breathing difficulties, body weight and preoperative Cormack-Lehane grade, for its correlation with perioperative PRS airway management decision. DESIGN Forty PRS children were retrospectively recruited after surgery. Specialists examined all subjects ...

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...

BACKGROUND The hyomental distance ratio is defined as the ratio of the hyomental distances in neutral position and at head extension. The aim of the study was to establish the diagnostic utility as predictor of difficult intubation. METHODS In a cross-sectional study, the assessment of the airway was performed in 70 patients (35 male and 35 female, 15-75 years old) undergoing general anesthes...

OBJECTIVE Recently, to further enhance the potential in the management of difficult airways, the highly angulated D-Blade was added to the C-MAC system. The purpose of this study was to investigate the laryngoscopic view and intubation parameters using the new C-MAC D-Blade in comparison to the conventional C-MAC video laryngoscope and Macintosh direct laryngoscope in simulated easy and difficu...

A formalism will be presented in this paper which makes it possible to realise the idea of assigning only one scope-ambiguous representation to a sentence that is ambiguous with regard to quantif ier scope. The scope de te rmina t ion resul ts in ex tending this representat ion with addit ional context and world knowledge conditions. If there is no scope determining information, the formalism c...
