ReviewThe definition of block "success" in the contemporary literature: are we speaking the same language?
A successful nerve block is the common goal that shapes modern regional anesthesia practice and research, yet the meaning of block "success" can be open to interpretation. For this Special Article, we reviewed all applicable randomized controlled trials published over the last decade to determine the most commonly used definitions of block success. We also sought to uncover which relevant indicators of block success are routinely reported in the contemporary literature. ⋯ Surgeon- and hospital administrator-related indicators were not collected in any trial. We found that the definition of block success is highly variable in the contemporary regional anesthesia literature. Our findings underscore the clear and present need for a comprehensive definition of block success, whereas future research should endeavor to capture the indicators of block success that are important to all key perioperative stakeholders.

In the last 2 decades, a growing body of research aimed at investigating the health benefits of Tai Chi in various chronic health conditions has been recognized in the literature. This article reviewed the history, the philosophy, and the evidence for the role of Tai Chi in a few selected chronic pain conditions. The ancient health art of Tai Chi contributes to chronic pain management in 3 major areas: adaptive exercise, mind-body interaction, and meditation. ⋯ Only 5 pain conditions were reviewed: osteoarthritis, fibromyalgia, rheumatoid arthritis, low back pain, and headache. Of these, Tai Chi seems to be an effective intervention in osteoarthritis, low back pain, and fibromyalgia. The limitations of the Tai Chi study design and suggestions for the direction of future research are also discussed.

Peripheral nerve stimulation has a long history in regional anesthesia. Despite the advent of ultrasound-guided peripheral nerve blockade, nerve stimulation remains a popular technique used alone or, now, in combination with ultrasound-guided techniques. In light of this evolving utility of nerve stimulation, this is an appropriate time to review the basic concepts and knowledge base of this historically important tool. ⋯ However, current magnitude is neither 100% sensitive nor specific. Independent of technical ability, both the biological environment and the equipment used impact the current-distance relationship. Thus, successful electrical nerve stimulation is dependent on an anesthesiologist with a solid foundation in anatomy and a thorough understanding of electrophysiology.

ReviewPulsed radiofrequency in the treatment of persistent pain after inguinal herniotomy: a systematic review.
In the United States, it is estimated that between 6000 and 18,000 individuals each year present with disabling pain after inguinal hernia repair. Although surgical treatment with mesh removal is one of few options available, effective alternatives to nonsurgical management are needed. The use of pulsed radiofrequency (PFR), leading to nondestructive lesions of nerve structures, has been proposed as a treatment option. ⋯ Pain relief varied between 63% and 100%, the follow-up period was 3 to 9 months, and no adverse effects or complications were reported. In conclusion, the evidence base of PRF in persistent pain after inguinal herniotomy is fairly limited. Suggestions for improved research strategies are presented.

ReviewEpidural technique for postoperative pain: gold standard no more?
Epidural analgesia is a well-established technique that has commonly been regarded as the gold standard in postoperative pain management. However, newer, evidence-based outcome data show that the benefits of epidural analgesia are not as significant as previously believed. There are some benefits in a decrease in the incidence of cardiovascular and pulmonary complications, but these benefits are probably limited to high-risk patients undergoing major abdominal or thoracic surgery who receive thoracic epidural analgesia with local anaesthetic drugs only. ⋯ The number of indications for the use of epidural analgesia seems to be decreasing for a variety of reasons. The decision about whether to continue using epidural techniques should be guided by regular institutional audits and careful risk-benefit assessment rather than by tradition. For routine postoperative analgesia, epidural analgesia may no longer be considered the gold standard.
