Interventional pain management has been growing by leaps and bounds with the introduction of an array of new CPT codes, the expansion of interventional techniques, and utilization. Interventional pain management dates back to the origin of neural blockade and regional analgesia, in 1884. Over the years, pain medicine and interventional pain management have taken many approaches, including biological, biopsychosocial, and psychosocial. ⋯ Overall, the utilization of various nerve blocks (excluding epidurals, disc injections, and facet joint blocks) in Medicare recipients from 1998 to 2003 were performed approximately 50% of the time by non-pain physicians. Interventional pain management is growing rapidly, under the watchful eye of the government, and third party payors. Establishing an algorithmic approach and following guidelines may improve compliance and quality of care without implications of abuse.

The purpose of this review is to present the most important recent studies into the clinical use of peripheral nerve blocks for anesthesia and postoperative analgesia of the lower limb surgery. ⋯ Introduction of new methods and techniques are increasing and improving the use of lower peripheral nerve blocks. These techniques are gaining interest after the important increase of the lower molecular weigh heparins.

Randomized Controlled Trial Comparative Study Clinical Trial
Analgesia and effectiveness of levobupivacaine compared with ropivacaine in patients undergoing an axillary brachial plexus block.
A common anesthetic technique for the upper extremity is local brachial plexus anesthesia using levobupivacaine and ropivacaine. To our knowledge, no study has been performed measuring differences in analgesic efficacy and latency when these local anesthetics are used for brachial plexus anesthesia. We enrolled 54 adults, assessed as ASA class I or II, into this double-blind, prospective investigation to receive 40 mL of 0.5% ropivacaine or levobupivacaine with 1:200,000 epinephrine. ⋯ Return of motor activity was significantly faster in the ropivacaine group (778 minutes) than in the levobupivacaine group (1,047 minutes; P = .001). No other significant differences were noted between the groups. When considering levobupivacaine and ropivacaine for brachial plexus anesthesia, levobupivacaine should be considered when postoperative analgesia is a concern but not when an early return of motor activity is required.
