Randomized Controlled Trial Comparative Study
Computerized training system for ultrasound-guided lumbar puncture on abnormal spine models: a randomized controlled trial.
A randomized controlled trial was carried out to determine whether Perk Tutor, a computerized training platform that displays an ultrasound image and real-time needle position in a three-dimensional (3D) anatomical model, would benefit residents learning ultrasound-guided lumbar puncture (LP) in simulation phantoms with abnormal spinal anatomy. ⋯ Residents trained with augmented reality 3D visualization had better performance metrics on ultrasound-guided LP in pathological spine models.

Review Meta Analysis Comparative Study
Efficacy of dexmedetomidine on postoperative shivering: a meta-analysis of clinical trials.
Shivering is a frequent complication in the postoperative period. The aim of the current meta-analysis was to assess the efficacy of dexmedetomidine on postoperative shivering. ⋯ The present meta-analysis indicates that dexmedetomidine shows superiority over placebo, but not over other anti-shivering agents. Therefore, considering its high price and potential adverse events, dexmedetomidine may not be appropriate solely for the purpose of the prevention of postoperative shivering.

Randomized Controlled Trial Comparative Study
Intubation with VivaSight or conventional left-sided double-lumen tubes: a randomized trial.
Double-lumen endotracheal tubes (DLTs), which are commonly used for single-lung ventilation during surgery, are difficult to insert. In addition, they often move during surgical lung manipulation which can cause life-threatening complications. Flexible bronchoscopy is used routinely to establish and confirm proper DLT placement. The newly designed VivaSight DLT has an integrated camera, allowing continuous visualization of its position in the trachea. We hypothesized that the time to intubation using the VivaSight DLT would be faster than with a conventional DLT. ⋯ The VivaSight DLT camera allowed faster insertion and facilitated initial positioning. It also confirmed proper tube positioning intraoperatively and facilitated repositioning when necessary. This trial was registered at clinicaltrials.gov: NCT01807676.
