Randomized Controlled Trial Comparative Study Clinical TrialPain relief after arthroscopic shoulder surgery: a comparison of intraarticular analgesia, suprascapular nerve block, and interscalene brachial plexus block.
In this prospective, randomized, blinded study, we assessed the analgesic efficacy of interscalene brachial plexus block (ISB), suprascapular nerve block (SSB), and intraarticular local anesthetic (IA) after arthroscopic acromioplasty. One-hundred-twenty patients were divided into 4 groups of 30. In Group SSB, the block was performed with 10 mL of 0.25% bupivacaine. ⋯ When compared with controls, a significant reduction in morphine consumption and a better satisfaction score were noted only in Group ISB. We conclude that ISB is the most efficient analgesic technique after arthroscopic acromioplasty. SSN block would be a clinically appropriate alternative.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of 3 different methods of anesthesia before transrectal prostate biopsy: a prospective randomized trial.
Periprostatic nerve block (PNB) is the most common anesthesia technique used before prostate biopsy. However, needle punctures for anesthetic infiltration may be painful and cause higher infectious complications. We assessed whether addition of rectal lidocaine gel would improve its efficacy. We also investigated the efficacy and safety of tramadol, a codeine derivative, as a noninvasive method. ⋯ Any form of analgesia/anesthesia was superior to none. The combination of PNB plus gel provided significantly better analgesia compared to PNB alone or tramadol. If this can be duplicated in other trials, the combination may be accepted as the new gold standard of anesthesia for prostate biopsy. The efficacy of tramadol was similar to that of PNB, and was free of complications. Therefore, tramadol may have a role before prostate biopsy, which needs to be explored.
