“…The 60° curvature of the Glide Scope blade with a light source and digital camera at the tip of it, enables intubation without the need to align the oral, pharyngeal and tracheal axes (25). It also needs less forceful laryngoscopy and results in less tissue trauma (15). It is rational to attribute less postoperative sore throat and hoarseness to less tissue trauma in the GVL group.…”

Background:The Glide Scope videolaryngoscope provides a suitable view for intubation, with less force required.Objectives:The present study was conducted, to compare postoperative sore throat and hoarseness after laryngoscopy and intubation, by Macintosh blade or Glide Scope video laryngoscope in normal airway patients.Patients and Methods:Three hundred patients were randomly allocated into two groups of 150: Macintosh blade laryngoscope or Glide Scope video laryngoscope. The patients were evaluated for 48 hours for sore throat and hoarseness by an interview.Results:The incidence and severity of sore throat in the Glide Scope group, at 6, 24 and 48 hours after the operation, were significantly lower than in the Macintosh laryngoscope group. In addition, the incidence of hoarseness in the Glide Scope group, at 6 and 24 hours after the operation, were significantly lower than in the Macintosh laryngoscope group. The incidence and severity of sore throat in men, at 6 and 24 hours after the operation, were significantly lower than in the women.Conclusions:The incidence and severity of sore throat and hoarseness after tracheal intubation by Glide Scope were lower than in the Macintosh laryngoscope. The incidence and severity of sore throat were increased by intubation and longer operation times.

“…[1][2][3] Video laryngoscopy has been demonstrated to improve first-pass and ultimate success and decrease iatrogenic airway trauma during endotracheal intubation in adults. [4][5][6] In addition to clinical benefit, the ability to review videos captured during laryngoscopy provides a unique opportunity to assess metrics related to procedural performance and quality of care. The C-MAC video laryngoscope blades (Karl Storz, Tuttlingen, Germany) are structurally similar to those of conventional laryngoscopes, but allow continuous recording of intubations.…”

Objectives: Using recordings of endotracheal intubation attempts obtained with a video-enabled laryngoscope with Miller and Macintosh blades, the authors sought to evaluate the association between laryngoscopic approach (right-sided vs. midline) and intubation success, as well as adverse event rates in the pediatric emergency department (ED).Methods: This was a retrospective cohort study of children younger than 21 years who underwent endotracheal intubation with a C-MAC video laryngoscope in a tertiary care ED between August 2009 and May 2013. The primary outcome was successful endotracheal intubation on the first attempt. The secondary outcomes included time to intubation, video-recorded adverse events (oropharyngeal mucosal injury and aspiration), and physiologic adverse events. Multivariate regression models were used to determine the relationship between laryngoscope blade position and outcome measures adjusted for patient and provider factors.Results: The cohort consisted of complete video recordings for 105 of 143 (73%) patient encounters with intubations. The first-pass success rate did not significantly differ based on laryngoscopic approach (adjusted odds ratio [aOR] = 0.76, 95% confidence interval [CI] = 0.29 to 2.0). Among patients successfully intubated on the first attempt, the median time to intubation was longer for the right-sided approach compared to the midline approach (42 seconds vs. 31.5 seconds; p < 0.05). The odds of mucosal injury and aspiration were higher among patients intubated using a right-sided approach compared to a midline approach (aOR = 4.1, 95% CI = 1.2 to 14.5; aOR = 7.7, 95% CI = 1.5 to 39.5, respectively). Rates of physiologic adverse events did not differ based on approach.Conclusions: First-pass success rate did not differ based upon laryngoscopic approach type; however, a right-sided approach was associated with a longer time to intubation, as well as higher rates of mucosal injury and aspiration among patients undergoing video-enabled intubation in a pediatric ED.

“…During the last 30 years, numerous investigators have studied the forces applied to manikins or the patient's airway during laryngoscopy [7][8][9][10][11][12][13], but only few researchers have focused on the operator's muscular activity and effort during the direct and indirect laryngoscopy [5,14].…”

Background: Successful endotracheal intubation requires mental activity and no less important physical activity from the anesthesiologist, so ergonomics of used devices is important. The aim of our study has been to compare 4 laryngoscopes regarding an operator's activity of selected muscles of the upper limb, an operator's satisfaction with used devices and an operator's fatigue during intubation attempts. Material and Methods: The study included 13 anesthesiologists of similar seniority. To measure muscle activity MyoPlus 2 with 2-channel surface ElectroMyoGraphy (sEMG) test device was used. Participant's satisfaction with studied devices was evaluated using Visual Analog Scale. An operator's fatigue during intubation efforts was evaluated by means of the modified Borg's scale. Results: The highest activity of all the studied muscles was observed for the Intubrite laryngoscope, followed by the Mackintosh, TruView Evo2 and the lowest one -for the King Vision video laryngoscope. A significant statistical difference was observed for the King Vision and the rest of laryngoscopes (p < 0.05). No significant statistical differences were observed between the Macintosh, TruView Evo2 and Intubrite laryngoscopes (p > 0.05). The shortest time of intubation was achieved using the standard Macintosh blade laryngoscope. The highest satisfaction was noted for the King Vision video laryngoscope, and the lowest for -the TruView Evo2. The Intubrite was the most demanding in terms of workload, in the opinion of the participants', and the least demanding was the King Vision video laryngoscope. Conclusions: Muscle activity, namely the force used for intubation, is the smallest when the King Vision video laryngoscope is used with the highest satisfaction and lowest workload, and the highest muscle activity was proven for the Intubrite laryngoscope with the highest workload.
