Pain relief could be easy with a simple injection

19.11.2004


A recent study, published in the journal Pain Practice, identified situations in which injections of local anesthetic would be the best treatment for pain and reduce unnecessary risk and procedural costs.

While the use of sympathetic blocks (injections) is controversial, in this study, 20 patients suffering from complex regional pain syndrome (CRPS) were given injections to examine the method’s contribution "as prospective predictors of outcome."

The patients, who exhibited allodynia, or pain with light touch, were given an initial "diagnostic" injection after which results were analyzed to determine if further treatments would be advantageous. This treatment consists of injections into the sympathetic nerves that run along the front side of the spinal column.



Those who showed at least a 50% improvement were treated with subsequent blocks. Patients who did show initial improvement were considered to have "sympathetically maintained pain" (SMP) and were also more likely to experience greater long-term improvement as well. Cases in which patients did not have significant improvement were considered to have "sympathetically independent pain" (SIP) and no further treatment was given.

Previous studies by Cepeda et al showed that less than one-third of CRPS patients are likely to respond to this type of procedure. "Reserving these invasive procedures for patients who will receive the greatest benefit could have significant value by reducing unnecessary risk for adverse events, as well as significant economic benefit by limiting the costs associated with unnecessary procedures," states lead researcher, Dr. Craig T. Hartrick.

Although this study was not randomized and was not placebo-controlled, it "speaks to the rational use of sympathetic block" and suggests that this procedure is especially useful when allodynia is present.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
