Cervical spine motion during tracheal intubation with King Vision™ video laryngoscopy and conventional laryngoscopy: a crossover randomized study.

Background: The King Vision™ (KVL) videolaryngoscope with a wide field of view could potentially reduce cervical spine motion during intubation. We aimed to compare the extent of cervical spine movement during laryngoscopy using the KVL and Macintosh laryngoscopes.

Methods: Following ethical approval, 29 patients with a normal cervical spine requiring general anesthesia and tracheal intubation were randomly subjected to both KVL and Macintosh laryngoscopy in a crossover.

Comparison of three videolaryngoscopes for double-lumen tubes intubation in simulated easy and difficult airways: a randomized trial.

Background: The King Vision™ (KVL) and Airtraq® videolaryngoscopes may reduce the time to double lumen tube (DLT) intubation compared to the GlideScope® and MacIntosh in simulated easy and difficult airways.

Methods: Twenty-one staff anesthesiologists with limited prior experience in using videolaryngoscopes for DLT intubation were assigned randomly to insert a DLT using the MacIntosh, GlideScope®, Airtraq® and KVL videolaryngoscopes on easy and difficult airway simulators in a randomized crossover order. Time to DLT intubation, laryngoscopic view, intubation difficulty, optimizing manoeuvers and failure to intubation - defined as an attempt taking longer than 150 s - were recorded.

Comparison of the Macintosh, GlideScope®, Airtraq®, and King Vision™ laryngoscopes in routine airway management.

Background: We hypothesized that the use of the channeled King Vision™ and Airtraq® would shorten the time for tracheal intubation compared with the Macintosh or GlideScope® laryngoscopes in patients with normal airways.

Methods: Eighty-six patients were randomly assigned to intubate the trachea using either the Macintosh (N.=22), Glidescope® (N.

Is sealing cuff pressure, easy, reliable and safe technique for endotracheal tube cuff inflation?: A comparative study.

Objective: To compare the three common methods of endotracheal tube cuff inflation (sealing pressure, precise standard pressure or finger estimation) regarding the effective tracheal seal and the incidence of post-intubation airway complications.

Methods: Seventy-five adult patients scheduled for N(2) O free general anesthesia were enrolled in this study. After induction of anesthesia, endotracheal tubes size 7.

Electives during medical internship.

Objective: The purpose of the study was to find out the reasons for selecting elective rotations during a rotating medical internship.

Methods: One hundred and seventy-eight medical interns in the College of Medicine, King Faisal University, Dammam, Kingdom of Saudi Arabia during the period March 2001 to August 2002 completed a questionnaire for their selection reasons with responses on a scale of 1-5.

Results: The study comprised 60% males and 98.

Successful separation of thoracopagus conjoined twins.

The first successful separation of thoracopagus conjoined twins in Eastern Saudi Arabia with 2-year follow up is presented. Physical examination and radiographic studies revealed a conjunction that extended from midsternum to a common umbilicus. The shared internal organs included liver and pericardium.
