Randomized Controlled Trial Clinical TrialAnalgesic effect of interscalene block using low-dose bupivacaine for outpatient arthroscopic shoulder surgery.
Although interscalene brachial plexus block (ISBPB) is often used to provide anesthesia for arthroscopic shoulder surgery, its selective analgesic effect, provided by low-dose local anesthetic, has not been studied. We hypothesized that ISBPB using a low volume and low concentration of bupivacaine can provide effective postoperative analgesia for shoulder surgery without producing significant sensory or motor block elsewhere. ⋯ Interscalene brachial plexus block with low-dose bupivacaine is a useful and selective analgesic technique for outpatient shoulder arthroscopic surgery.

Case ReportsContinuous sciatic nerve infusion: expanded case report describing a new approach.
Severe pain following extensive reconstructive foot surgery is difficult to manage effectively. Sciatic nerve block provides excellent analgesia for a limited duration. I wanted to determine an approach to sciatic nerve block enabling an infusion of a local anesthetic for a prolonged period without loss of efficacy due to catheter displacement. ⋯ The described "in line" technique of continuous sciatic nerve infusion of a local anesthetic solution gives prolonged and effective analgesia following foot surgery.

Randomized Controlled Trial Comparative Study Clinical TrialThe paravertebral nerve root block for inguinal herniorrhaphy--a comparison with the field block approach.
Our objective was to evaluate the efficacy of the paravertebral block for inguinal herniorrhaphy by comparison with the well-established field block. ⋯ The paravertebral nerve root block proved to be superior to the field block, to be devoid of side effects, and was acceptable to the patients.

Randomized Controlled Trial Comparative Study Clinical Trial
A double-blind study of axillary brachial plexus block by 0.75% ropivacaine or 2% mepivacaine.
Axillary brachial plexus block using 20 mL of 0.75% ropivacaine or 2% mepivacaine was compared in a prospective, randomized, double-blind study of two groups of 15 patients. The times to onset of sensory and motor block and to resolution of motor block, as well as the time to onset and degree of post-operative pain were recorded by an observer blinded to the identity of drug. ⋯ Nine patients who received ropivacaine and two patients who received mepivacaine did not require further post-operative analgesia (P < 0.05). Ropivacaine is less toxic than other long-acting local anaesthetics, and 0.75% ropivacaine may be better for brachial plexus block when fast onset is required and prolonged pain relief is useful.
