Effect of superficial and deep parasternal blocks on recovery after cardiac surgery: study protocol for a randomized controlled trial.

Background: Pain is frequent after cardiac surgery and source of multiple complications that can impair postoperative recovery. Regional anesthesia seems to be an interesting technique to reduce the pain in this context, but its effectiveness in improving recovery has been poorly studied so far. The objective of this study is to compare the effectiveness of two of the most studied chest wall blocks in cardiac surgery, i.

Spin and fragility in randomised controlled trials in the anaesthesia literature: a systematic review.

Background: Given variable frequency of misleading reports and the potential for spin (a way of describing results that can mislead readers) to influence interpretation of randomised controlled trials (RCTs), we have undertaken a spin reassessment. We evaluated the quality of recent literature in anaesthesia journals by assessing the presence of spin and calculating the fragility index.

Methods: This systematic review of randomised trials was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.
