Randomized Controlled Trial
Gabapentin does not improve multimodal analgesia outcomes for total knee arthroplasty: a randomized controlled trial.
This study assessed whether gabapentin given preoperatively and for two days postoperatively (in addition to patient-controlled analgesia [PCA] morphine, acetaminophen, and ketorolac) is effective in reducing morphine requirements and moderating pain scores when compared with placebo for primary total knee arthroplasty. ⋯ Gabapentin 600 mg po given preoperatively followed by 200 mg po every eight hours for two days has no effect on postoperative morphine consumption, pain scores, patient satisfaction, or length of hospital stay. This trial is registered at ClinicalTrials.gov NCT01307202.

This study is a feasibility assessment to determine the ability of novice users to utilize an infrared (IR) sensor stylet as a guide to position the tip of the endotracheal tube (ETT) 40 mm proximal to the carina in the swine trachea. ⋯ The IR sensor stylet system can facilitate correct positioning of the ETT tip at an appropriate depth above the carina in the swine trachea. Evaluation of the IR sensor stylet methodology in human subjects is warranted.

Randomized Controlled Trial
The use of an online three-dimensional model improves performance in ultrasound scanning of the spine: a randomized trial.
The use of ultrasound for neuraxial blockade is a new application of technology that is rapidly becoming accepted as a standard of care. This new skill has shown to improve success, but it is a challenge to teach. To assist with teaching the use of ultrasound in regional anesthesia of the lumbar spine, we have developed an interactive educational model ( http://pie.med.utoronto.ca/vspine or http://www.usra.ca/vspine.php ). In this study, we aimed to determine whether use of this model for a two-week period would improve the performance of novice operators in determining defined landmarks during real-time ultrasound imaging of the lumbar spine. ⋯ Our results show superior performance by the residents who had access to both components of the module, indicating that access to the interactive ultrasound spine module improves knowledge and skills prior to clinical care.

Randomized Controlled Trial Comparative Study
Comparison of the Truview PCD™ and the GlideScope(®) video laryngoscopes with direct laryngoscopy in pediatric patients: a randomized trial.
The GlideScope(®) video laryngoscope has a 60° angled blade and the blade of the Truview PCD™ video laryngoscope has an optical lens that provides a 46° refraction of the viewing angle. Despite successful results using the GlideScope in adults, few studies have been published regarding its use in pediatric patients. We therefore tested our joint primary hypothesis that the GlideScope and the Truview PCD video laryngoscopes provide superior visualization to direct laryngoscopy and are non-inferior regarding time to intubation. ⋯ The Cormack-Lehane views attained using the GlideScope and the Truview PCD video laryngoscopes were not superior to views attained using direct laryngoscopy. Visualization with the GlideScope was significantly worse than with direct laryngoscopy. Use of the GlideScope and Truview PCD systems should be restricted to patients with specific indications.
