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
Celecoxib pharmacogenetics and pediatric adenotonsillectomy: a double-blinded randomized controlled study.
Pediatric adenotonsillectomy (A&T) is associated with prolonged pain and functional limitation. Celecoxib is an effective analgesic in adult surgery patients; however, its analgesic efficacy on pain and functional recovery in pediatric A&T patients is unknown. ⋯ A three-day course of oral celecoxib reduces early pain and co-analgesic consumption; however, an increase in dose, dose frequency, and duration of dose may be required for sustained pain relief in the pediatric setting. The CYP2C9*3 allele may influence recovery. This trial was registered at: ClinicalTrials.gov: NCT00849966.

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.

Observational Study
The impact of pneumoperitoneum and Trendelenburg positioning on respiratory system mechanics during laparoscopic pelvic surgery in children: a prospective observational study.
The aim of this study was to describe the changes in respiratory system compliance and other measures of respiratory mechanics associated with peritoneal insufflation (12 mmHg pressure) with carbon dioxide (PNP12) and 20° Trendelenburg positioning (TDG20) in pediatric patients undergoing laparoscopic surgery for abdominal cryptorchidism. ⋯ The PNP12 significantly decreases Cdyn/kg and VT/kg in pediatric patients. The use of TDG20 produces a relatively minor additional impact in respiratory mechanics. This study emphasizes the need to adjust ventilator settings to maintain normal gas exchange during this procedure.

Case Reports
Extracorporeal membrane oxygenation for blastomycosis-related acute respiratory distress syndrome: a case series.
Blastomyces dermatitidis is a dimorphic fungus endemic to North America capable of causing fatal respiratory failure. Acute respiratory distress syndrome (ARDS) complicates up to 10% of pulmonary blastomycosis in hospitalized patients and carries a mortality of 50-90%. This report describes the clinical course of four consecutive patients with blastomycosis-related ARDS treated with venovenous extracorporeal membrane oxygenation (ECMO) during 2009-2014. ⋯ This report describes the successful application of ECMO as rescue therapy in aid of four patients with refractory blastomycosis-associated ARDS. In addition to early appropriate antimicrobial therapy, transfer to an institution experienced with ECMO should be considered when caring for patients from endemic areas with rapidly progressive respiratory failure.
