DRUG PREVENTS POSTPARTUM HEMORRHAGE IN RESOURCE POOR SETTINGS 
Advance Has Potential to Save Thousands of Lives 

The drug misoprostol provides a safe, convenient, and inexpensive means
to prevent postpartum hemorrhage, a major killer of women in developing
countries.  The study was conducted by researchers from the University
of Missouri, India's Jawaharlal Nehru Medical College, and the National
Institutes of Health.

Postpartum hemorrhage is excessive bleeding experienced by the mother
after giving birth.  The condition can result from failure of the uterus
to contract after detachment of the placenta or from ruptures or tears
in the uterus and other tissues.

The study, conducted with women in rural India, appeared in the October
7 "Lancet", and was funded by the Global Network for Women's and
Children's Health Research, a public-private partnership between NIH's
National Institute of Child Health and Human Development and the Bill
and Melinda Gates Foundation.   The NICHD Global Network for Women's and
Children's Health Research supports research based on sound scientific
evidence.  The Network supports research seeking to improve medical
treatments, procedures and preventive measures that will reduce death
and disability in women, infants, and children in resource
poor-countries.  Only interventions which are cost-effective and
appropriate for use in developing countries are evaluated by the
network.  The Global Network pairs U.S. and foreign investigators to
increase scientific capacity, research infrastructure, and
sustainability.

The study was conducted by researchers in the United States and India.
The American team, led by Richard J. Derman, M.D., M.P.H, of the
University of Missouri-Kansas City School of Medicine, also included
Nancy Moss, Ph.D. from NICHD.  The Indian authors of the study included
Bhalchandra S. Kodkany, M.D, and colleagues from the Jawaharlal Nehru
Medical College, Belgaum, Karnataka.

"The researchers showed that giving women misoprostol after birth is a
safe, inexpensive means to prevent postpartum hemorrhage from
occurring," said NIH Director Dr. Elias A. Zerhouni.  "This advance has
the potential to save thousands of lives each year."

In developed countries, where the majority of births occur in hospitals
and emergency care is available, deaths from postpartum hemorrhage are
rare.  However, the condition can be life-threatening in countries where
most births occur at home and emergency care is not always available.

The study authors noted that in rural India, 50 percent of births occur
at home or in facilities without a physician in attendance.  The
estimated maternal death rate in that country is 407 women for every
100,000 births.  The study authors also cited estimates that, worldwide,
about 500,000 maternal deaths occur during childbirth each year, with
postpartum hemorrhage accounting for about 30 percent of those deaths.
The comparable rate in the U.S. is about 10 maternal deaths per 100,000
births, with postpartum hemorrhage accounting for about 17 percent of
these deaths.

In developed countries, oxytocin is the standard drug used to prevent
postpartum hemorrhage, explained Nancy Moss, the NICHD author and
project officer for the study.  The drug stops bleeding in the uterus by
causing the uterus to contract.  But oxytocin should be kept cold, and
must be given by trained medical personnel -- conditions that make it
unsuitable for use in parts of the world where most births are at home
and refrigeration and skilled medical personnel are in short supply.

But the drug misoprostol, which also stops uterine bleeding by causing
the uterus to contract, does not require refrigeration.  It can be given
once after delivery as 3 oral tablets costing as little as $.14 each.
Its use does not require highly trained personnel and it can be given by
semi-skilled birth attendants.   

The researchers conducted the current study to determine if misoprostol
could provide an effective way to prevent postpartum hemorrhage in
countries where hospital services are in limited supply.  Between
September, 2002 and December 2005, Dr. Kodkany and colleagues from
Jawaharlal Nehru Medical College recruited 25 nurse midwives who serve
the rural villages of the Belgaum District in Karnataka State.  The
nurse midwives were instructed how to administer the 3 tablets of
misoprostol and how to measure blood loss following the birth.  To
provide an accurate measure of blood loss, the researchers developed a
calibrated plastic blood collection drape that measures blood loss.  The
drape was placed underneath the reclining woman after she had given
birth.

Women who volunteered to participate were randomized early in labor to
receive either 600 micrograms of misoprostol or an identical looking
placebo immediately after they gave birth.  Only women who did not have
any serious health problems were enrolled into the study.   Of the 1620
women who took part, 812 received misoprostol, and 808 received a
placebo.  Neither the nurse midwives nor the women knew who received
misoprostol and who received the placebo.

The study authors found that women who received misoprostol were less
likely to experience acute postpartum hemorrhage, which was defined as
the loss of from 500 milliliters to just under 1000 milliliters of blood
(slightly more than a pint to slightly more than a quart.)  "Only 6.4
percent of the women receiving misoprostol experienced acute postpartum
hemorrhage, compared with 12 percent in the placebo group," Dr. Moss
said.

Dr. Moss added that misoprostol also significantly reduced the average
blood loss of women who received the drug.

The women in the misoprostol group also had fewer occurrences of acute
severe postpartum hemorrhage -- the loss of 1000 milliliters or more of
blood.  Overall, the researchers reported that one case of postpartum
hemorrhage was prevented for every 18 women treated.

Side effects of the misoprostol treatment consisted of a modest increase
in shivering and fever, both common side effects of the drug.  Infants
of nursing mothers who took misoprostol showed no side effects.

"We now have proven that misoprostol is a convenient, inexpensive, safe,
and effective drug to lessen a major cause of death of women in the
developing world -- postpartum hemorrhage," Dr. Moss said.
