Manual, low-tech method for 2nd trimester abortions found safe and effective

01.10.2003


Useful in developing countries



A hand-held vacuum aspiration device works as well as a more expensive electrical one for ending second-trimester pregnancies, according to results of a study by Johns Hopkins obstetricians published in the October issue of the International Journal of Gynecology & Obstetrics.

"Now that we know the low-tech device is safe and effective, it can be taught to doctors in developing nations to help reduce the prevalence of unsafe abortions and complications," says Paul D. Blumenthal, M.D., M.P.H., senior author of the paper and an associate professor of gynecology and obstetrics at Johns Hopkins.


The more costly electrical devices and the electricity needed to power them often are not available in less developed parts of the world, but there had been questions about comparative quality of the two methods. The manual technique had been commonly used for first-trimester abortions, but never for second-trimester abortions.

The Hopkins investigators compared both techniques while performing second-trimester abortions on 110 women who came to the Johns Hopkins Bayview Medical Center for this service between January 1998 and September 2000. The patients’ average age was 23.4 years, with an average gestation of 16 weeks.

Doctors performed manual vacuum aspiration on 73 women and electric vacuum aspiration on 37 women. There were no significant differences in procedure time between the two groups, and no complications reported.

In vacuum aspiration, doctors use either a hand-held specially designed syringe or a hollow tube hooked up to an electrical pump to apply suction inside the cervix, removing the uterine contents. The manual instrument is approved by the U.S. Food and Drug Administration for first-trimester abortions but had not been tested for second-trimester abortions, which are usually performed using the electric-powered aspirator.

In the United States, only 12 percent of abortions are performed in the second trimester of pregnancy, Blumenthal says.

"Generally, women who request a second-trimester abortion are those who need it most -- either teenagers, who may deny the pregnancy at first or don’t know where to turn, or older women who have an unexpected pregnancy and other children to care for," he says.

Study coauthors were C.S. Todd, M.E. Soler, L. Castleman, and M.K. Rogers.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
