Randomized Controlled Trial Comparative Study Clinical TrialEffects of brachial plexus fentanyl on supraclavicular block. A randomized, double-blind study.
The study examined the effects of adding fentanyl to mepivacaine supraclavicular blocks on block characteristics and postoperative analgesia. ⋯ Adding fentanyl 75 micrograms to mepivacaine supraclavicular blocks has no significant effects on block characteristics. It may enhance postoperative analgesia, but the duration of this effect is too brief to be clinically useful.

Randomized Controlled Trial Clinical TrialCan pre-emptive interpleural block reduce perioperative anesthetic and analgesic requirements?
The hypothesis that preoperative interpleural block might reduce intraoperative anesthetic and analgesic requirements and modify the intensity of postoperative pain was examined in this double-blind, randomized, saline-controlled study. ⋯ Preoperative interpleural block, during a background isoflurane anesthetic, reduces the hemodynamic response to surgery and the intraoperative anesthetic and analgesic requirements. Preoperative interpleural block with plain bupivacaine results in significant reductions in mean arterial pressure and heart rate, probably related to unilateral sympathetic block and the concomitant use of isoflurane. The timing of interpleural block, that is, pre-emptive versus postoperative, does affect the intensity of postoperative pain or the request for supplementary analgesia.

Case ReportsSuprascapular nerve block by catheter for breakthrough shoulder cancer pain.
Incidental shoulder pain due to movement renders pain control difficult because it requires high basal dosages or additional doses of opioids. Shoulder pain can be alleviated by suprascapular nerve block, and the placement of a catheter can permit the injection of local anesthesia as needed. ⋯ Continuous suprascapular nerve block is safe and simple and has proven to be useful in avoiding extra doses of opioids.
