Randomized Controlled Trial
A randomized-controlled trial of high- or low-volume intravenous Plasma-Lyte(®) to prevent hypotension during sedation for colonoscopy.
The purpose of this study was to compare the incidence of hypotension during sedation in adults presenting for elective colonoscopy and randomized to intravenous Plasma-Lyte 148(®) at either 2 mL·kg(-1) (low volume) or 20 mL·kg(-1) (high volume). ⋯ This study does not support the routine use of 20 mL·kg(-1) of intravenous Plasma-Lyte 148 to prevent hypotension and other complications during sedation for elective colonoscopy in adult patients.

Randomized Controlled Trial Comparative Study
A deliberately restricted laryngeal view with the GlideScope® video laryngoscope is associated with faster and easier tracheal intubation when compared with a full glottic view: a randomized clinical trial.
During video laryngoscopy (VL) with angulated or hyper-curved blades, it is sometimes difficult to complete tracheal intubation despite a full view of the larynx. When using indirect VL, it has been suggested that it may be preferable to obtain a deliberately restricted view of the larynx to facilitate passage of the endotracheal tube. We used the GlideScope® GVL video laryngoscope (GVL) to test whether deliberately obtaining a restricted view would result in faster and easier tracheal intubation than with a full view of the larynx. ⋯ Using the GVL with a deliberately restricted view of the larynx resulted in faster and easier tracheal intubation than with a full view and with no additional complications. Our study suggests that obtaining a full or Cormack-Lehane grade 1 view may not be desirable when using the GVL. This trial was registered at ClinicalTrials.gov: NCT02144207.
