Review Comparative StudyMethodological quality of randomized controlled trials of postoperative epidural analgesia: validation of the Epidural Analgesia Trial Checklist as a specific instrument to evaluate methodology.
The overall benefits of epidural analgesia are controversial, in part because of the varying quality of methodology in published randomized controlled trials (RCTs). We performed a systematic review of available RCTs to examine the methodological quality of epidural analgesia trials. Current instruments for evaluating the quality of methodology are generic; thus, we also developed a specific assessment tool named Epidural Analgesia Trial Checklist (EATC). ⋯ Methodology scores for epidural analgesia RCTs have improved over time. The EATC seems to correlate well with other commonly used generic assessments for methodological RCT quality and be useful for assessing methodological quality of epidural RCTs. Future epidural analgesia RCTs should focus on improving appropriate description/definition of adverse effects, proper presentation of VAS pain scores, and assessment of VAS pain both at rest and with activity.

ReviewBenefits, risks, and best practice in regional anesthesia: do we have the evidence we need?
For more than 25 years, regional anesthesia has challenged anesthesiologists to determine whether it offers real benefits in terms of patient outcome from major surgery, compared with general anesthesia. Although there is good evidence that regional analgesia offers superior pain relief to systemic opioid analgesia, evidence to support improved outcome from surgery remains elusive. ⋯ We are beginning to develop an evidence base for both the benefits and risks of regional anesthesia, when used for specific patient groups and for specific surgical procedures. This presentation looks at some of the evidence and examines how it can be used to develop guidelines for best practice.
