Magnesium sulfate therapy affects attention and working memory in patients undergoing preterm labor

Article Abstract:

Magnesium sulfate could affect a pregnant woman's mental processes, which could make it difficult to obtain informed consent for invasive procedures such as fetal blood sampling. Magnesium sulfate is often given to pregnant women in premature labor. It does not seem to affect long-term memory, however.

Randomized trial of McRoberts versus lithotomy positioning to decrease the force that is applied to the fetus during delivery

Article Abstract:

The objective of this study is to evaluate whether the delivery force in multiparous patients is reduced with the prophylactic McRoberts maneuver as compared with the lithotomy position under actual delivery conditions with the use of a force-measuring glove. In general the McRoberts' maneuver is considered safe, but there are anecdotal reports of maternal injuries that are associated with its extended use, so it may be wise to reserve the maneuver for clinical diagnosis of shoulder dystocia only.

Angiogenin: a marker for preterm delivery in midtrimester amniotic fluid

Article Abstract:

A marker for preterm delivery may be evident in midtrimester amniotic fluid. Researchers evaluated amniotic fluid obtained through midtrimester amniocentesis for levels of angiogenin, a substance that promotes development of new blood vessels. Angiogenin levels were much higher among the 11 women with spontaneous preterm deliveries compared to the levels of 33 women with term deliveries. The presence of angiogenin may indicate that the placenta supplies an insufficient amount of blood, since the body's response to lack of blood is to create new blood vessels.
