Comparative Study
[Analgesic alternatives for the control of postoperatory pain in radical mastectomy].
The purpose of preventive analgesia based on regional blocks with local anesthetics is to avoid sharp and hard-to-control pain in the anterior side of thorax and axilla secondary to radical mastectomy. ⋯ Preventive analgesia by direct transoperational block on nerves turned out to be an effective alternative with low level of systemic morbidity, which must be considered to prevent moderate and severe pain syndromes that are difficult to control in thoracic oncological surgery.

Randomized Controlled Trial Comparative Study Clinical TrialLumbar segmental nerve blocks with local anesthetics, pain relief, and motor function: a prospective double-blind study between lidocaine and ropivacaine.
Selective segmental nerve blocks with local anesthetics are applied for diagnostic purposes in patients with chronic back pain to determine the segmental level of the pain. We performed this study to establish myotomal motor effects after L4 spinal nerve blocks by lidocaine and ropivacaine and to evaluate the relationship with pain. Therefore, 20 patients, of which 19 finished the complete protocol, with chronic lumbosacral radicular pain without neurological deficits underwent segmental nerve blocks at L4 with both lidocaine and ropivacaine. ⋯ A difference in effect on MVMF was found for affected versus control side (P = 0.016; Tukey test). Multiple regression revealed a significant negative correlation for change in VNRS score versus change in median MVMF (Spearman R = -0.48: P = 0.00001). This study demonstrates that in patients with unilateral chronic low back pain radiating to the leg, pain reduction induced by local anesthetic segmental nerve (L4) block is associated with increased quadriceps femoris and tibialis anterior MVMF, without differences for lidocaine and ropivacaine.

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.
