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: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
