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.

Randomized Controlled TrialEvaluation of the depth and duration of anesthesia from heated lidocaine/tetracaine (Synera) patches compared with placebo patches applied to healthy adult volunteers.
The heated lidocaine/tetracaine patch (Synera; ZARS Pharma, Inc, Salt Lake City, UT) is among the local topical anesthetic formulations used to prevent procedural pain. This study was conducted to determine the depth and duration of anesthesia provided by the patch and to evaluate safety and tolerability. ⋯ The heated lidocaine/tetracaine patch is well tolerated, and it provides favorable depth and duration of anesthesia without significant sensory loss for superficial venous access and minor dermatological procedures after a 30-min application.

Randomized Controlled Trial Comparative StudyA randomized comparison between ultrasound-guided and landmark-based superficial cervical plexus block.
This prospective, randomized, observer-blinded study compared ultrasound guidance and the conventional landmark-based technique for superficial cervical plexus blockade. ⋯ Ultrasound guidance does not increase the success rate of superficial cervical plexus block compared with a landmark-based technique. Additional confirmatory trials are required.
