Review Meta AnalysisWound infiltration with local anesthetics for post-operative pain relief in lumbar spine surgery: a systematic review.
In this systematic review, we evaluated double-blind, randomized and controlled trials on the effect of wound infiltration with local anesthetics compared with the effect of placebo on post-operative pain after lumbar spine surgery. ⋯ Interpretation of the results was difficult because of diversity of the studies. However, clinical significance was in general questionable, with only a few trials showing a small or a modest reduction in pain intensity, which was observed mainly immediately after the operation. Similarly, although more frequently observed, only a minor and probably not clinically relevant reduction in opioid consumption was shown.

Review Meta AnalysisPercutaneous tracheostomy, a systematic review.
Percutaneous dilatational tracheostomy (PDT) is a common procedure in intensive care units and the identification of the best technique is very important. We performed a systematic review and meta-analysis of randomized studies comparing different PDT techniques in critically ill adult patients to investigate if one technique is superior to the others with regard to major and minor intraprocedural complications. ⋯ Among the six analyzed techniques, single-step dilatation technique appeared the most reliable in terms of safety and success rate. However, the number of available randomized trials was insufficient to confidently assess the best PDT technique.
