Randomized Controlled TrialEarly Endotracheal Tube Insertion with the GlideScope: A Randomized Controlled Trial.
The GlideScope videolaryngoscope is an intubating device routinely used by anesthesiologists for tracheal intubation. It is occasionally difficult to advance the endotracheal tube (ETT) into the trachea, despite a good view of the glottis. One technique that may be used when difficulty is encountered is to remove the GlideScope from the pharynx and introduce the ETT into the pharynx first, leaving it in place posteriorly while the GlideScope is inserted. Frequently, when the GlideScope is subsequently inserted, the ETT tip will then be in good view, resting near the glottis, and will easily advance into the trachea. In this randomized, single-blinded trial, we assessed whether orotracheal intubation with the GlideScope is faster and/or easier with the ETT-first technique as a primary technique in elective patients. ⋯ In this study of GlideScope laryngoscopy, no statistically significant difference was observed in the time to intubate or the subjective ease of intubation whether the ETT or GlideScope was inserted into the oropharynx first.

Randomized Controlled Trial Multicenter Study Comparative StudyFirst-Attempt Intubation Success of Video Laryngoscopy in Patients with Anticipated Difficult Direct Laryngoscopy: A Multicenter Randomized Controlled Trial Comparing the C-MAC D-Blade Versus the GlideScope in a Mixed Provider and Diverse Patient Population.
Intubation success in patients with predicted difficult airways is improved by video laryngoscopy. In particular, acute-angle video laryngoscopes are now frequently chosen for endotracheal intubation in these patients. However, there is no evidence concerning whether different acute-angle video laryngoscopes can be used interchangeably in this scenario and would allow endotracheal intubation with the same success rate. We therefore tested whether first-attempt intubation success is similar when using a newly introduced acute-angle blade, that is an element of an extended airway management system (C-MAC D-Blade) compared with a well-established acute-angle video laryngoscope (GlideScope). ⋯ Head-to-head comparison in this large multicenter trial revealed that the newly introduced C-MAC D-Blade does not yield the same first-attempt intubation success as the GlideScope in patients with predicted difficult laryngoscopy except in the hands of attending anesthesiologists. Additional research would be necessary to identify potential causes for this difference. Intubation success rates were very high with both systems, indicating that acute-angle video laryngoscopy is an exceptionally successful strategy for the initial approach to endotracheal intubation in patients with predicted difficult laryngoscopy.

Randomized Controlled TrialSaline Flush After Rocuronium Bolus Reduces Onset Time and Prolongs Duration of Effect: A Randomized Clinical Trial.
Circulatory factors modify the onset time of neuromuscular-blocking drugs. Therefore, we hypothesized that infusion of a saline flush immediately after rocuronium administration would shorten the onset time without influencing the duration of the rocuronium effect. ⋯ Administering a 20-mL saline flush immediately after infusion of 0.6 mg/kg rocuronium in 10 mL normal saline shortened the onset time and prolonged the recovery phase of neuromuscular blockade.
