The non-pneumatic anti-shock garment (NASG) is a low-technology first-aid device used to treat hypovolemic shock. Its efficacy for reducing maternal deaths due to obstetrical hemorrhage is being researched. Obstetrical hemorrhage is heavy bleeding of a woman during or shortly after a pregnancy. Current estimates suggest over 300,000 women die every year, of which 99% occurs in developing countries, most of which are preventable. Many women in resource-poor settings deliver far from health-care facilities. Once hemorrhage has been identified, many women die before reaching or receiving adequate treatment. The NASG can be used to keep women alive until they can get the treatment they need. ==Background== Every year, an estimated 342,900 women die from complications of pregnancy and childbirth, 99% of these deaths occur in developing countries.〔 Worldwide, for every 100,000 live births, about 251 women die. In some industrialized countries such as the U.S, this is 13 deaths for every 100,000 live babies born with American women having a lifetime risk of 1 in 2,100 of dying from childbirth related complications. However, in some countries, such as Afghanistan up to 1,600 women die for every 100,000 live births and women have a 1 in 11 lifetime risk of maternal death.〔UNICEF. Information by Country - Statistics - Women's Health. Accessed August 29, 2011 from http://www.unicef.org/infobycountry/index.html; 2010.〕 For every woman who dies, there are 30 women who suffer a disability as a result of pregnancy or childbirth related complications (a maternal morbidity) and 10 who experience a ‘near miss mortality’ (a life-threatening obstetric complication).〔WHO. Beyond the Numbers: Reviewing Maternal Deaths and Complications to Make Preganancy Safer. Geneva: WHO; 2004.〕 Morbidities can be serious, lifelong ailments which compromise a woman's health, productivity, quality of life, family health and ability to participate in community life. If a mother dies after childbirth, the newborn is ten times more likely to die before the age of two, other children are more likely to suffer from decreased nutrition and decreased schooling. Many motherless families find it difficult to survive, often with older children having to drop out of school in order to work to help support the family or being sent to live with a relatives intact family. In addition to this, maternal and newborn deaths are estimated to cost the world $15 billion in lost productivity annually, with maternal health proven to support a country's economic growth and cut poverty.〔(【引用サイトリンク】title=2004 Policy Budget: Program Highlights )〕 Maternal death and disability is a human rights issue. It also means hardships and loss of productivity for families, communities and nations. This is of such great concern that in 2000, world leaders decided that improving maternal health should be one of the 8 Millennium Development Goals for the international community. The leading cause of maternal mortality (deaths from pregnancy and childbirth related complications) is obstetric hemorrhage in which a woman bleeds heavily, most often immediately after giving birth.〔WHO, UNICEF, UNFPA. Maternal mortality in 2000: Estimates developed by WHO, UNICEF and UNFPA; 2004.〕 A woman dies every 4 minutes from this kind of complication. A woman can bleed to death in two hours or less, and in rural areas, where hospitals may be days away, this leaves little hope for women suffering from hemorrhage.〔Maine D. Safe Motherhood Programs: Options and Issues. New York, NY: Center for Population and Family Health, Columbia University; 1993.〕 Also, in areas that have limited resources, clinics and hospitals might not have the staff or supplies needed to save a woman's life. Women die waiting for treatment.〔AMDD. Workbook: Using the UN Process Indicators of Emergency Obstetric Services. Questions and Answers.: The Averting Maternal Death and Disability Program (AMDD); 2003 May.〕 There are some emerging technologies which are currently being researched and implemented that seek to prevent these unnecessary deaths.〔Tsu VD, Shane B. New and underutilized technologies to reduce maternal mortality: call to action from a Bellagio workshop. Int J Gynaecol Obstet. 2004 Jun;85 Suppl 1:S83-93〕 One of these is the NASG which is a low-technology first-aid device that can be placed around the lower body of a woman who has gone into shock from obstetric bleeding. This garment decreases blood loss, recovers women from shock and keeps them alive while they are traveling to a hospital or awaiting treatment.〔Miller S, Ojengbede A, Turan JM, Ojengbede O, Butrick E, Hensleigh P.
