Randomized Controlled Trial
Two methods for teaching basic upper airway sonography.
The purpose of this study was to evaluate and compare hands-on gel phantom versus instructional video teaching methods to improve anesthesia residents and staff members' ability to correctly identify airway structures using ultrasound on a human volunteer. ⋯ Use of either a low cost, airway gel phantom training model for hands-on training or a simple instructional teaching video can be used in a single training session to improve staff anesthesiologist and anesthesia resident knowledge and skills for ultrasound identification of upper airway anatomy.

Randomized Controlled Trial Comparative Study
The comparison of insertion depth for orotracheal intubation between standard polyvinyl chloride tracheal tubes and straight reinforced tracheal tubes.
To investigate whether these properties of reinforced tubes cause difference in insertion depth compared to standard polyvinyl chloride tracheal tubes. ⋯ The insertion depth of straight reinforced tracheal tubes can be shorter than that of standard polyvinyl chloride tracheal tubes due to different tube pathways in the upper airway.

Randomized Controlled Trial
Cardiovascular safety of hydroxypropyl-β-cyclodextrin-diclofenac in the management of acute postsurgical pain: a pooled analysis of 2 randomized, double-blind, placebo- and active comparator-controlled phase III clinical trials.
Long-term use of nonsteroidal anti-inflammatory drugs, including selective and nonselective cyclooxygenase inhibitors, has been suggested to be associated with cardiovascular (CV) safety risks. Data are limited regarding CV risks associated with short-term nonsteroidal anti-inflammatory drug use, including injectable formulations, although it has been suggested that even a single dose may increase CV adverse event (AE) risk. The objective of this study was to examine the CV safety of an injectable diclofenac formulation solubilized with hydroxypropyl-β-cyclodextrin (HPβCD) when given for ≤5days postoperatively. ⋯ Although a longer duration follow-up study in a larger patient population would expand our understanding of potential CV risks, the present analysis suggests that postoperative use of HPβCD-diclofenac does not present an added CV safety risk over placebo.

Randomized Controlled Trial
Do mask aperture bars of extraglottic airway devices prevent prolapse of epiglottis causing airway obstruction? A randomized crossover trial in anesthetized adult patients.
The study objective is to determine whether extraglottic airway devices (EADs) with or without mask aperture bars (MABs) result in similar anatomical positions in patients undergoing surgery. ⋯ This study demonstrated that the anatomical position of the four tested single-use EADs is similar with or without mask aperture bars. We therefore question whether MABs have a protective role in prevention of airway occlusion and whether MABs are essential components. In the overall majority of EADs with MABs, the latter did not prevent contact with the epiglottis. Contact and herniation of the laryngeal structures are seen more frequently when more than two MABs are present.

Randomized Controlled Trial Comparative Study
Comparison of three video laryngoscopy devices to direct laryngoscopy for intubating obese patients: a randomized controlled trial.
To compare three different video laryngoscope devices (VL) to standard direct laryngoscopy (DL) for tracheal intubation of obese patients undergoing bariatric surgery. ⋯ Video-Mac and GlideScope required fewer intubation attempts than standard DL and the McGrath device. The Video-Mac also significantly reduced the time needed to secure the airway and improved the glottic view compared to standard DL.
