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
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 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.

Randomized Controlled Trial
A randomized placebo-controlled study of preoperative pregabalin for postoperative analgesia in patients with spinal surgery.
To determine whether single preoperative administration of 2 different doses of pregabalin (75 and 150 mg) could decrease postoperative pain intensity and opioid consumption following posterior lumbar interbody fusion surgery. ⋯ Single preoperative administration of 150 mg of pregabalin 2 hours prior to surgery reduced postoperative pain intensity and morphine consumption compared with 5 mg diazepam in patients who underwent posterior lumbar interbody fusion.

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.
