Randomized Controlled Trial Comparative StudyPostoperative analgesic efficacy of peripheral levobupivacaine and ropivacaine: a prospective, randomized double-blind trial in patients after total knee arthroplasty.
Several previous trials have characterized the intra- and postoperative effects of the recently introduced local anesthetics, levobupivacaine and ropivacaine, for a variety of continuous peripheral nerve blocks. ⋯ Both levobupivacaine 0.125% and ropivacaine 0.2% provide similar analgesia after total knee arthroplasty with the latter being less potent.

Randomized Controlled TrialUltrasound guidance improves the success of sciatic nerve block at the popliteal fossa.
Real time ultrasound guidance is a recent development in the area of peripheral nerve blockade. There are limited data from prospective randomized trials comparing its efficacy to that of traditional nerve localization techniques. In the present study, we tested the hypothesis that ultrasound guidance improves the success rate of sciatic nerve block at the popliteal fossa when compared with a nerve stimulator-guided technique. ⋯ Ultrasound guidance enhances the quality of popliteal sciatic nerve block compared with single injection, nerve stimulator-guided block using either a tibial or peroneal endpoint. Ultrasound guidance resulted in higher success, faster onset, and progression of sensorimotor block, without an increase in block procedure time, or complications.

Randomized Controlled Trial Controlled Clinical TrialValue of diagnostic lumbar selective nerve root block: a prospective controlled study.
Although diagnostic lumbar selective nerve root blocks are often used to confirm the pain-generating nerve root level, the reported accuracy of these blocks has been variable and their usefulness is controversial. The purpose of this study was to evaluate the accuracy of diagnostic lumbar selective nerve root blocks to analyze potential causes of false results in a prospective, controlled, single-blinded manner. ⋯ The accuracy of diagnostic lumbar selective nerve root blocks is only moderate. To improve the accuracy, great care should be taken to avoid inadequate blocks and overflow, and to precisely interpret spot radiographs.

Randomized Controlled Trial Comparative StudyUltrasonographic guidance improves the success rate of interscalene brachial plexus blockade.
The use of ultrasonography in regional anesthetic blocks has rapidly evolved over the past few years. It has been speculated that ultrasound guidance might increase success rates and reduce complications. The aim of our study is to compare the success rate and quality of interscalene brachial plexus blocks performed either with direct ultrasound visualization or with the aid of nerve stimulation to guide needle placement. ⋯ The use of ultrasound to guide needle placement and monitor the spread of local anesthetic improves the success rate of interscalene brachial plexus block.

Randomized Controlled Trial Comparative Study
Topical prilocaine-lidocaine cream combined with peripheral nerve block improves pain control in prostatic biopsy: results from a prospective randomized trial.
To compare pain control results between periprostatic nerve block alone and combined with topical prilocaine-lidocaine cream as local anesthesia of prostate biopsy. ⋯ Combined prilocaine-lidocaine cream topically placed with PNB is superior to PNB alone and may be of maximum benefit for younger patients.
