Randomized Controlled Trial Clinical TrialEfficacy of EMLA cream prior to dorsal penile nerve block for circumcision in children.
While circumcision may be performed solely with dorsal penile nerve block (DPNB), some painful steps in its use are skin needle penetration and infiltration of the anesthetic product. The objective of this study was to evaluate the efficacy of EMLA cream, prior to DPNB for circumcision in children. ⋯ Since the dorsal penile nerves are located under the Buck's fascia, topical anesthesia may not reach them and other techniques may be necessary to anesthetize them. We found that although EMLA cream is efficient as a topical anesthesia during needle penetration for DPNB, it has no beneficial effect during infiltration.

Randomized Controlled Trial Comparative Study Clinical Trial
[Comparison of transarterial technique and paresthesia technique of axillary brachial plexus block].
Axillary brachial plexus blocks were established in 40 patients using transarterial technique (n = 20) or paresthesia technique (n = 20). Sensory and motor blockades of nerves supplying the upper extremity were compared at 10, 20 and 30 minutes after the injection of local anesthetics (1.5% plain mepivacaine 40 ml). Sensory blockades of the radial nerve and axillary nerve were significantly higher with transarterial technique than paresthesia technique. ⋯ Proximal and distal spreads of the local anesthetic-contrast medium mixture within the axillary neurovascular sheath were studied in 20 patients. No statistically significant difference was observed in the spread of contrast agent between the two techniques. Transarterial technique is a recommendable method for hand surgery and especially indicated for the surgery of the area supplied by the radial nerve.

The effects and side effects of interscalene brachial plexus block by posterior approach.
To investigate the use of interscalene block by posterior approach in upper extremity surgery and its effects on routine pulmonary function tests. ⋯ Interscalene block by posterior approach did not provide a satisfactory anesthesia for forearm and hand surgery. This method also caused hemidiaphragmetic paresis and a reduction in pulmonary function tests as in the lateral approach of Winnie. We believe limitations and relative contraindications for interscalene block by lateral approach are the same for posterior approach.

Comparative StudyHigh thoracic epidural block relieves acute herpetic pain involving the trigeminal and cervical regions: comparison with effects of stellate ganglion block.
Stellate ganglion block can promptly relieve acute herpetic pain (AHP) involving the trigeminal and cervical regions. However, repeated blocks are needed to maintain pain relief in most patients with severe AHP. Because continuous epidural block is easily performed using an indwelling catheter, we compared the effect of high thoracic epidural block with that of stellate ganglion block to relieve moderate-to-severe AHP involving these regions. ⋯ High thoracic epidural block was as effective as stellate ganglion block in relieving moderate-to-severe AHP involving the trigeminal and cervical regions.
