Summary Introduction:, Direct laryngoscopy can be challenging in infants and neonates. Even with an optimal line of sight to the glottic opening, the viewing angle has been measured at 15°. The STORZ DCI video laryngoscope (Karl Storz, Tuttlingen, Germany) incorporates a fiberoptic camera in the light source of a standard laryngoscope of variable sizes. The image is displayed on a screen with a viewing angle of 80°. We studied the effectiveness of the STORZ DCI as an airway tool compared to standard direct laryngoscopy in children with normal airway. Methods:, In this prospective, randomized study, 56 children (ages 4 years or younger) undergoing elective surgery with the need for endotracheal intubation were divided into two groups: children who underwent standard direct laryngoscopy using a Miller 1 or Macintosh 2 blade (DL) and children who underwent video laryngoscopy using the STORZ DCI video laryngoscope with a Miller 1 blade (VL). Time to best view (TTBV), time to intubate (TTI), Cormack,Lehane (CL), and percentage of glottis opening seen (POGO) score were recorded. Results:, TTBV in DL was 5.5 (4,8) s and 7 (4.2,9) s in VL. TTI in DL was 21 (17,29) s and in VL 27 (22,37) s (P = 0.006). The view as assessed by POGO score was 97.5% (60,100%) in DL and 100% (100,100%) in the VL (P = 0.003). Data are presented as median and interquartile range and analyzed using t -test. Discussion:, This study demonstrates that the STORZ DCI video laryngoscope provides an improved view to the glottis in children with normal airway anatomy, but requires a longer time for intubation.

Evaluation of the McGrath® Series 5 videolaryngoscope after failed direct laryngoscopy,

Summary Unanticipated difficulties during tracheal intubation and failure to intubate are among the leading causes of anaesthesia-related morbidity and mortality. Using the technique of video laryngoscopy, the alignment of the oral and pharyngeal axes to facilitate tracheal intubation is unnecessary. In this study we evaluated the McGrath® Series 5 videolaryngoscope for tracheal intubation in 61 patients who exhibited Cormack and Lehane grade 3 or 4 laryngoscopies with a Macintosh laryngoscope. Using the McGrath resulted in an improved glottic view, compared to Macintosh laryngoscope. Laryngoscopy was improved by one grade in 10%, by two grades in 80% and by three grades in 10% of cases (p < 0.0001). The success rate for intubation was 95% with the McGrath. These results suggest that the McGrath videolaryngoscope can be used with a high success rate to facilitate tracheal intubation in difficult intubation situations. [source]


A Comparison of GlideScope Video Laryngoscopy Versus Direct Laryngoscopy Intubation in the Emergency Department

ACADEMIC EMERGENCY MEDICINE, Issue 9 2009

Abstract Objectives:, The first-attempt success rate of intubation was compared using GlideScope video laryngoscopy and direct laryngoscopy in an emergency department (ED). Methods:, A prospective observational study was conducted of adult patients undergoing intubation in the ED of a Level 1 trauma center with an emergency medicine residency program. Patients were consecutively enrolled between August 2006 and February 2008. Data collected included indication for intubation, patient characteristics, device used, initial oxygen saturation, and resident postgraduate year. The primary outcome measure was success with first attempt. Secondary outcome measures included time to successful intubation, intubation failure, and lowest oxygen saturation levels. An attempt was defined as the introduction of the laryngoscope into the mouth. Failure was defined as an esophageal intubation, changing to a different device or physician, or inability to place the endotracheal tube after three attempts. Results:, A total of 280 patients were enrolled, of whom video laryngoscopy was used for the initial intubation attempt in 63 (22%) and direct laryngoscopy was used in 217 (78%). Reasons for intubation included altered mental status (64%), respiratory distress (47%), facial trauma (9%), and immobilization for imaging (9%). Overall, 233 (83%) intubations were successful on the first attempt, 26 (9%) failures occurred, and one patient received a cricothyrotomy. The first-attempt success rate was 51 of 63 (81%, 95% confidence interval [CI] = 70% to 89%) for video laryngoscopy versus 182 of 217 (84%, 95% CI = 79% to 88%) for direct laryngoscopy (p = 0.59). Median time to successful intubation was 42 seconds (range, 13 to 350 seconds) for video laryngoscopy versus 30 seconds (range, 11 to 600 seconds) for direct laryngoscopy (p < 0.01). Conclusions:, Rates of successful intubation on first attempt were not significantly different between video and direct laryngoscopy. However, intubation using video laryngoscopy required significantly more time to complete. [source]
