Randomized Controlled Trial Comparative Study Clinical Trial
Clinical and radiological comparison of perivascular and transarterial techniques of axillary brachial plexus block.
The perivascular technique of axillary brachial plexus block results in incomplete block of radial and musculocutaneous nerves in 10-20% of patients. With the transarterial technique and a large dose of mepivacaine, success rates of 99% have been reported. We have compared the clinical efficacy of these techniques in 50 patients using 1% mepivacaine 45 ml with adrenaline. ⋯ There were no statistically significant differences in sensory or motor block between the groups at 20 min or in the plasma concentrations of mepivacaine measured 0-45 min after injection. In the CT scans, both proximal and distal spread of the contrast medium were more common after perivascular than after transarterial block. The distribution of the contrast medium was not related to the efficacy of the block.

Randomized Controlled Trial Clinical Trial
Improved postoperative analgesia with morphine added to axillary block solution.
To determine whether the addition of morphine to the axillary block local anesthetic solution provides improved or prolonged postoperative analgesia. ⋯ The addition of morphine 0.1 mg/kg to the local anesthetic axillary block solution provided improved postoperative analgesia without an increased frequency of side effects or major complications.

Randomized Controlled Trial Clinical Trial
The effects of streptomycin/lidocaine block on trigeminal neuralgia: a double blind crossover placebo controlled study.
This study investigated the long term effect of a peripheral sensory block using streptomycin sulphate on trigeminal neuralgia. A total of twenty subjects, thirteen with idiopathic trigeminal neuralgia (ITN) and seven with traumatic trigeminal neuralgia (TTN) were studied. A double-blind placebo controlled randomized design was used. ⋯ The sensory function of the treated nerves was also not affected. Side effects including facial swelling and pain were a common finding in the patients receiving streptomycin. This study demonstrated no beneficial effects of streptomycin blockade for idiopathic and traumatic trigeminal neuralgia.

Randomized Controlled Trial Clinical TrialThe effect of continuous interscalene brachial plexus block with 0.125% bupivacaine plus fentanyl on diaphragmatic motility and ventilatory function.
Continuous interscalene brachial plexus block with 0.25% bupivacaine decreases diaphragmatic motility and ventilatory function. The author studied the effects of 0.125% bupivacaine with and without fentanyl. ⋯ Use of 0.125% bupivacaine for continuous interscalene block did not prevent a deterioration of diaphragmatic motility and ventilatory function. Co-infusion of fentanyl did not significantly potentiate the block.

Randomized Controlled Trial Comparative Study Clinical Trial
Buffered versus plain lidocaine for digital nerve blocks.
To test whether buffered lidocaine is less painful to administer as a digital nerve block than plain lidocaine. ⋯ Because it causes less pain and is equally efficacious, buffered lidocaine is preferable to plain lidocaine for digital nerve blocks in adults.
