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 TrialUltrasound imaging for stellate ganglion block: direct visualization of puncture site and local anesthetic spread. A pilot study.
Stellate ganglion block (SGB) inhibits sympathetic innervation and is a common treatment for reflex sympathetic dystrophy. During the positioning of the needle, there is a risk of injury to the adjacent structures. The aim of the study was to develop an ultrasonographic imaging technique for the performance of SGB. ⋯ Ultrasonographic guided SGB may improve safety and allows the visualization of the local anesthetic depot. Studying the local anesthetic spread might allow the avoidance of side effects as well as typical complications of SGB.

Does the addition of morphine to brachial plexus block improve analgesia after shoulder surgery?
We have studied 40 patients undergoing elective shoulder surgery for chronically painful conditions. Patients were allocated randomly to two groups and received interscalene brachial plexus block with 0.5% bupivacaine and adrenaline 1/200,000 40 ml either alone or with the addition of morphine 5 mg. ⋯ The quality of the block, analgesic requirements and any complications or side effects were noted in the intraoperative period and during the 48 h after operation. No significant difference was seen in quality of analgesia or patient satisfaction between the two groups.

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.
