A number of studies in the West have shown that heavy bleeding following childbirth has become more common in recent years. In her thesis, midwife and researcher Elisabeth Jangsten decided to look at how heavily women bleed after giving birth in Angola and Sweden following active and expectant management.
The study in Angola covered 1,590 women, while the Swedish study included 1,802. The Swedish study was conducted at two of the delivery units at Sahlgrenska University Hospital, which make use of both active and expectant management.Active management means that the umbilical cord is clamped straight after the baby is delivered, the midwife gives the mother medication to stimulate uterine contractions, presses a hand on the lower part of the uterus, and pulls gently on the umbilical cord while the mother pushes, so delivering the placenta. With an expectant approach, the umbilical cord is also clamped straight after the baby is delivered, but the midwife then waits for signals that the placenta has separated from the wall of the uterus before encouraging the mother to bear down and push out the placenta. Uterine stimulants are always given if the need arises.
“In Angola, 7.5% of women lost more than a litre of blood in the expectantly managed group, and only 1% in the actively managed group,” says Jangsten, a midwife at Sahlgrenska University Hospital/Östra Hospital and researcher at the Institute of Health and Care Sciences at the Sahlgrenska Academy. “In Sweden, the difference was bigger: almost 17% of women lost more than a litre in the expectantly managed group, and only 10% in the actively managed group.”The researchers did not find any difference between the two methods in terms of perceived afterpains in either Sweden or Angola. However, afterpains were more common the more children the women had had. They also found that first-time mothers in Sweden lost more blood and were more likely to require a blood transfusion than those who had given birth before. More women bled heavily in the Swedish study, which can be explained partly by all blood being measured carefully during the course of the study, but may also be down to other factors, such as excess weight, big babies and greater intervention during childbirth.
The recommendation in Sweden has been to give mothers uterine stimulants immediately after delivery.
“In the light of our results in this thesis, I think that active management should be the first choice for hospital deliveries. However, women should be informed about the different methods available so that they can be involved in decisions about the management of the third stage of labour if they so wish.”POSTPARTUM HAEMORRHAGE

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...

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...
