Randomized Controlled Trial Comparative StudyA prospective, randomized comparison between single- and double-injection ultrasound-guided infraclavicular brachial plexus block.
This prospective, randomized, observer-blinded study compared single- and double-injection ultrasound-guided infraclavicular brachial plexus block for upper extremity surgery. ⋯ The double-injection ultrasound-guided infraclavicular block provides no significant advantages compared with its single-injection counterpart.

Randomized Controlled TrialLong-lasting analgesic effects of intraoperative thoracic epidural with bupivacaine for liver resection.
Continuous epidural analgesia may be considered in liver resection but is often avoided because of possible coagulopathies and the risk of epidural hematoma in the postoperative period. On the other hand, there is no coagulation defect during the surgery. Effective prevention of postoperative pain may require continuous sensory ablation throughout the surgery event. ⋯ Intraoperative thoracic epidural infusion of bupivacaine, added to intrathecal morphine, decreased postoperative morphine consumption with better pain relief compared with the placebo.

Randomized Controlled TrialAnalgesic effectiveness of a continuous versus single-injection interscalene block for minor arthroscopic shoulder surgery.
The utility of continuous perineural infusions for lesser painful shoulder procedures is not well established. We hypothesized that the addition of a continuous interscalene ropivacaine infusion to a single-injection interscalene block would improve analgesia after minor arthroscopic shoulder surgery. ⋯ After minor arthroscopic shoulder surgery, the addition of a continuous interscalene ropivacaine infusion to a single-shot interscalene block reduces pain, especially with movement, during the first 24 hrs.

Randomized Controlled Trial Comparative StudyAxillary block by "selective" injections at the nerves involved in surgery using a peripheral nerve stimulator: a comparison with a "standard" triple-injection technique.
A triple-injection technique (injections at the median, musculocutaneous, and radial nerves) for axillary block affords a high incidence of complete block (all the nerves below the elbow). However, in certain surgeries, only 1 or 2 nerves are involved in the surgical field. The aim of this prospective randomized study was to test the effectiveness of surgical anesthesia of a "selective" approach in which only the nerves involved in surgery were electrically located and injected. ⋯ A standard triple-nerve stimulation technique seems to be preferable to the selective approach even when a limited number of nerves are involved in the surgical field.
