“…In other manikin and clinical studies, a video laryngoscope provided a good laryngeal view or high POGO score. 13,14 In the present study, the IS had a mean POGO score of 75% AE 23%, similar to other videolaryngoscopes.…”

Comparison between video-lighted stylet (Intular Scope™) and direct laryngoscope for endotracheal intubation in patients with normal airway

Objective The Intular Scope™ (Medical Park, South Korea) (IS) is a video-lighted stylet that can be used for endotracheal intubation with excellent visualization by adding a camera to its end. We compared the efficacy of a direct laryngoscope (DL) with that of the IS based on hemodynamic changes, ease of intubation, and postoperative airway morbidities. Methods Seventy patients with expected normal airways were randomized for intubation using an IS (n = 35) or DL (n = 35). The primary outcome was the mean arterial pressure during intubation. The secondary outcomes were the time to intubation (TTI), percentage of glottic opening (POGO) score, and number of intubation attempts. The incidence and severity of bleeding, hoarseness, and sore throat after intubation were also recorded. Results Hemodynamic changes during intubation were not significantly different between the groups. The TTI was longer in the IS than DL group. The POGO score was higher in the IS than DL group. Hoarseness and sore throat were significantly less severe in the IS than DL group. Conclusions Using the IS did not significantly improve hemodynamics and resulted in a longer TTI. However, the IS was associated with less severe postoperative airway morbidities compared with the DL.

“…Therefore, an observer effect might have occurred during the performance of intubation and affected the hemodynamic responses. 13 Third, because we only compared the IS and DL, further studies comparing the IS with other lighted stylets or videolaryngoscopes might produce different results.…”

“…Einige SR deuten auf ein erhöhtes Risiko einer verlängerten Intubationszeit und einer erfolglosen Intubation mit Videolaryngoskopie hin [ 192 – 194 ]. Neuere RCT- und Beobachtungsstudien deuten auf einen Vorteil hin, aber die Evidenzen bleiben widersprüchlich [ 195 – 202 ]. Wichtig ist, dass ein solcher Vorteil stark davon abhängt, wer die Intubation durchführt, welche Technik und welches Gerät für welche Indikation verwendet werden.…”

“…Relevant paediatric intubation study reported an intubation time of a mean 27.5 seconds with a standard deviation of 8.9 seconds. 15 The minimum number of patients for each group resulted in 62, and considering the 10% dropout rate, we planned to enroll 68 patients for each group (α = 0.05, β = 0.2).…”

Funding informationDepartmental source. Background: Pentax Airway Scope (AWS) is a recently developed videolaryngoscopefor use in both normal and difficult airways, yet its use in paediatric patients has not been established. The purpose of this study was to evaluate the efficacy of the Pentax AWS regarding intubation time, laryngeal view and ease of intubation in paediatric patients with normal airway, compared to Macintosh laryngoscope.Method: A total of 136 paediatric patients aged 1-10 with American Society of Anaesthesiologists physical status I or II undergoing general anaesthesia were randomly allocated into two groups: Macintosh laryngoscope (n = 68) and Pentax Airway Scope (n = 68). Primary outcome was intubation time. Cormack-Lehane laryngeal view grade, application of optimal laryngeal external manipulation, intubation difficulty scale, intubation failure rate and adverse events were also measured.Result: No significant difference was observed between the two groups regarding intubation time (P = 0.713). As for the laryngeal view grade, the Pentax group resulted in lower graded cases compared to the Macintosh group (P = 0.000). No optimal laryngeal external manipulation application was required in the Pentax group.Intubation difficulty scale resulted in lower values for Pentax group (P = 0.001).Failure rate was not different between the two groups (P = 0.619). There were significantly more teeth injury cases in the Pentax group than Macintosh group (P = 0.042).Conclusion: Pentax Airway Scope provided similar intubation time and success rate, while improving laryngeal view, compared to Macintosh laryngoscopy in children with normal airway. When using Pentax AWS in children, however, the risk of teeth injury may increase.
