Randomized Controlled Trial Clinical TrialThe addition of epinephrine increases intensity of sensory block during epidural anesthesia with lidocaine.
Little is known about the effect of adding epinephrine to local anesthetic solutions on the intensity of sensory block during epidural anesthesia. This study examined development of sensory block during lumbar epidural anesthesia using a cutaneous current perception threshold (CPT) quantitative sensory testing device. ⋯ These results suggest that lumbar epidural anesthesia using 10 mL 1% lidocaine with epinephrine produces a more intense block of both large and small diameter sensory nerve fibers than that with plain lidocaine. It appears, therefore, that the addition of epinephrine improves the quality of sensory block during epidural anesthesia with lidocaine.

Randomized Controlled Trial Clinical TrialDouble-injection method using peripheral nerve stimulator is superior to single injection in axillary plexus block.
Axillary block using a single-injection method does not always provide effective analgesia. This study examined whether a double axillary block injection technique is superior to a single injection axillary block. ⋯ A double-injection method in axillary block provides excellent analgesia and motor block compared with a single-injection method. Moreover, the need for supplemental nerve blocks is significantly decreased.

Randomized Controlled Trial Clinical Trial
Alkalinizing local anesthetic does not decrease pain during injection for dorsal penile nerve block.
To evaluate whether alkalizing local anesthetic with sodium bicarbonate reduces pain related to infiltration of local anesthetic during dorsal penile nerve block for circumcision. ⋯ Alkalinizing the acidic local anesthetic solution by sodium bicarbonate does not decrease pain related to infiltration during penile nerve block for circumcision.

Comparative Study Clinical Trial Controlled Clinical TrialUse of EMLA cream or alfentanil for analgesia during ophthalmic nerve blocks.
This prospective double-blind study compared the effectiveness of EMLA with alfentanil and placebo in reducing the overall pain during ophthalmic nerve blocks. Seventy-five patients scheduled for cataract surgery were divided into three groups. ⋯ Patients then received facial nerve blocks and retrobulbar block by the same surgeon. Pain scores by patients and independent observers were significantly lower in the EMLA and alfentanil groups compared to placebo (P < 0.005) with no significant difference between the EMLA and alfentanil groups.

In adults, peripheral nerve block provides an effective alternative to general anesthesia. In pediatric anesthesia practice, several factors may limit the use of such techniques. ⋯ Cervical plexus block was used to provide surgical anesthesia for superficial/deep lymph node biopsy and excision of a thyroid nodule. The technique for cervical plexus block and its possible application in the practice of pediatric anesthesia are reviewed.
