Randomized Controlled Trial Clinical Trial
Capacity of the clinical picture to characterize low back pain relieved by facet joint anesthesia. Proposed criteria to identify patients with painful facet joints.
Prospective randomized study to compare the efficacy of facet joint injection with lidocaine and facet joint injection with saline in two groups of patients with low back pain, with and without clinical criteria that were determined in a previous study to implicate the facet joint as the primary source of the pain. ⋯ A set of five clinical characteristics can be used in randomized studies to select lower back pain that will be well relieved by facet joint anesthesia. These characteristics should not, however, be considered as definite diagnostic criteria of lower back pain originating from facet joints.

Randomized Controlled Trial Comparative Study Clinical TrialThe paravertebral nerve root block for inguinal herniorrhaphy--a comparison with the field block approach.
Our objective was to evaluate the efficacy of the paravertebral block for inguinal herniorrhaphy by comparison with the well-established field block. ⋯ The paravertebral nerve root block proved to be superior to the field block, to be devoid of side effects, and was acceptable to the patients.

Randomized Controlled Trial Clinical TrialAnalgesic effect of interscalene block using low-dose bupivacaine for outpatient arthroscopic shoulder surgery.
Although interscalene brachial plexus block (ISBPB) is often used to provide anesthesia for arthroscopic shoulder surgery, its selective analgesic effect, provided by low-dose local anesthetic, has not been studied. We hypothesized that ISBPB using a low volume and low concentration of bupivacaine can provide effective postoperative analgesia for shoulder surgery without producing significant sensory or motor block elsewhere. ⋯ Interscalene brachial plexus block with low-dose bupivacaine is a useful and selective analgesic technique for outpatient shoulder arthroscopic surgery.
