Randomized Controlled Trial
Standard and flexible tip bougie for tracheal intubation using a non-channelled hyperangulated videolaryngoscope: a randomised comparison.
Bougie impingement during tracheal intubation can increases the likelihood of prolonged intubation time, failed intubation and airway trauma. A flexible tip bougie may overcome this problem, which can occur when using a non-channelled, hyperangulated videolaryngoscope with a standard bougie. This randomised controlled study compared standard and flexible tip bougies using a non-channelled videolaryngoscope (C-MAC® D-blade) in 160 patients. ⋯ There was no significant differences in laryngoscopy time, total tracheal intubation time, first attempt success rate and postoperative sore throat between the two groups. Both the flexible tip and standard bougies can be used with a high first attempt success rate for tracheal intubation using a C-MAC D-blade videolaryngoscope. The flexible tip bougie demonstrated a significantly better modified intubation difficulty scale score and lower incidence of bougie impingement.

Review Meta AnalysisVideolaryngoscopes versus direct laryngoscopes in children: ranking systematic review with network meta-analyses of randomized clinical trials.
Videolaryngoscopes improve tracheal intubation in adult patients, but we currently do not know whether they are similarly beneficial for children. We designed this ranking systematic review to compare individual video and direct laryngoscopes for efficacy and safety of orotracheal intubation in children. ⋯ Videolaryngoscopes reduce the risk of failed first intubation attempts and major complications in children compared to direct laryngoscopes. However, not all videolaryngoscopes have the same performance metrics, and more data is needed to clarify which device may be better in different clinical scenarios. Additionally, care must be taken while interpreting our results and rankings due to the available evidence's low or very low quality.

Observational StudyPredictors of difficult intubation when using a videolaryngoscope with an intermediate-angled blade during the first attempt: a prospective observational study.
The curvature of a videolaryngoscope blade has been diversified from the standard macintosh-type to the hyperacute-angle-type, resulting in different performances. We aimed to determine the intubation success rate and identify predictors of difficult intubation when using an intermediate-angled videolaryngoscope in the first attempt of intubation under routine anaesthesia settings. We enrolled 808 patients between 19 and 79 years of age, scheduled for elective surgeries under general anaesthesia with orotracheal intubation from July 2017 to November 2018; patients who were candidates for awake intubation were excluded. ⋯ The use of the UEScope demonstrated a 99.4% success rate for intubation; however, increased difficulties were observed in patients who were male, obese, had a short thyromental distance, limited mouth opening, and high upper-lip-bite test class. Despite the high intubation success rate using an intermediate-angled videolaryngoscope, we recommend preparing backup plans, considering the increased difficulty in patients with certain preoperative features.
