The researchers report a success rate of 100% for ultrasound-guided catheterisation of the internal jugular vein. They show that the method is less likely to result in blood stream infections or complications, such as puncture of an artery, than the normal catheterisation procedure.
Dimitrios Karakitsos, from the Intensive Care Unit of the General State Hospital of Athens in Greece (the echolabicu team), and colleagues from other institutions in Greece, The Netherlands and the USA, compared the outcome of internal jugular vein catheterisation in 450 patients for whom the procedure was guided by ultrasound and in 450 patients for whom physical landmarks were used for guidance. During the ultrasound-guided catheterisation, the physician is helped by ultrasound-generated, real-time, two-dimensional images of the jugular vein. The patients were matched between the two groups for age, gender, BMI and risk factors for complications following catheterisation.
Karakitsos et al.’s results show an overall success rate of 100% for ultrasound-guided catheterisation and a 94% success rate for the standard procedure. Very few cases of carotid puncture or hematoma, and no cases of hemothorax or pneumothorax, were reported following ultrasound-guided catheterisation. By contrast, hematoma occurred in 8.4% of patients who had a standard catheterization. Hemothorax occurred in 1.7% and carotid artery puncture occurred in 10.6% of the patients undergoing standard catheterisation. Karakitsos et al.’s results also show that 16% of patients who received the standard procedure had a central venous catheter associated blood stream infection, compared to 10.4% of patients who had the ultrasound-guided procedure. The time taken to insert the catheter and the number of attempts were also greatly reduced for patients who received the ultrasound-guided procedure.
The authors conclude: “Ultrasound imaging is a readily available technology and may be employed by inexperienced operators to facilitate the placement of a central venous catheter as well as by experienced operators in order to improve the safety of the procedure.”
In an accompanying commentary, Andrew Bodenham from Leeds General Infirmary in the UK adds: “In the past, it was possible to defend clinicians not using ultrasound on the basis that it was not yet routine practice but I think this position will become increasingly untenable in the future.”

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
