To extract experimental data of importance for the understanding of neurotoxicity of local anesthetics, with special reference to continuous spinal anesthesia. ⋯ Correctly administered LAs of clinical concentration are safe, but animal data indicate that all LAs are potentially neurotoxic. The neurotoxicity seems to be a function of the concentration of the LA and the time of exposure of the nervous tissue to the LA. Concomitant neural trauma, ischemia, or both, may potentiate the neurotoxic effect of the LA.

Comparative StudyComparison of the clinical efficacy of three perivascular techniques for axillary brachial plexus block.
This study compared the efficacy of three perivascular techniques of axillary block. ⋯ There was no significant difference in the number of patients requiring supplementation, with five patients in the back group (25%), three patients in the front group (15%), and one patient in the half and half group (5%) requiring supplementation for the surgical procedure.

Medial branch blocks are specific for the diagnosis of cervical zygapophyseal joint pain.
To determine the specificity of cervical medial branch blocks for the diagnosis of cervical zygapophyseal joint pain by ascertaining the disposition of the local anesthetic after injection of the medial branches of the cervical dorsal rami. ⋯ Local anesthetic blocks of the cervical medial branches are a specific test for the diagnosis of cervical zygapophyseal joint pain. The local anesthetic always reaches the target nerve and does not affect any other diagnostically important structures.
