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: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
