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.

Randomized Controlled Trial Clinical TrialEffects of epidural bupivacaine after thoracotomy.
Combinations of bupivacaine and fentanyl are popular for postoperative epidural analgesia. However, there are little data from which to select a rational dose of bupivacaine. The study examined the effects of increasing amounts of epidural bupivacaine on postoperative analgesia, epidural fentanyl consumption, and side effects after thoracotomy. ⋯ The results demonstrate improved analgesia with physiotherapy and significant opioid sparing when 10 and 5 mg/h doses of bupivacaine are used. However, the incidence of orthostasis may be increased with the use of 10 mg/h. Thus, 5 mg/h of epidural bupivacaine (.05% at 10 mL/h) improved analgesia, decreased opioid requirements, and did not have detectable hemodynamic effects.
