Lumbar facet arthropathy is an important cause of low back pain and sciatica. Intra-articular facet block can confirm symptomatic facet joint disease. Good understanding of the anatomy of the joint and fluoroscopic control are essential for intra-articular placement of anesthetics and steroids.

Comparative Study[Histomorphologic assessment of the effectiveness of anesthesia during tooth preparation].
The efficacy of conduction anesthesia with 2% solutions of novocain, celnovocain, trimecain, lidocain during the preparation of teeth for metal crowns was studied in experiments on 16 dogs by neurohistological and histochemical examination of the Gasserian and superior cervical ganglions, the nodose ganglion, teeth and pericoronal tissues. It was established that in terms of the degree of anesthesia efficacy increase, the test anesthetics can be arranged as follows: novocain, celnovocain, trimecain, lidocain.

Age and the spread of local anesthetic solutions in the epidural space.
Sensory level of anesthesia following the injection of 20 ml of 1.5% lidocaine with epinephrine (1:200,000) in 238 adult males averaged T7.7, T5.6, and T5.1 at 10, 20, and 30 minutes, respectively. Patient age had no significant effect on local anesthetic requirements per spinal segment per unit height until age 40 years, which age the calculated amount of local anesthetic decreased significantly to 0.62 ml from 0.69 ml/segment/meter of height. ⋯ Patient height was inversely related to sensory level (p < 0.001). Time required for anesthesia ro recede to T12 averaged 164 minutes and was slightly but significantly (p < 0.05) prolonged with advancing age.

The use of inflammable anesthetics in the United States has been debated widely over the past several years. Those in favor of continued use of these agents argue for educational use, professional freedom, pharmacologic safety, and the need to retain an option. Those in favor of a ban on such agents cite the lack of demonstrated pharmacologic advantage, diminishing physician expertise, risk of fire, and cost. ⋯ As their use declines further, the cost per patient increases because most of the costs are fixed. We advocate a ban on inflammable anesthetics. Without definitive action on the part of policy makers, the use of these agents is likely to continue at a very low, and hence a relatively expensive, rate.
