Postpartum Bleeding
Postpartum bleeding or postpartum hemorrhage (PPH) is often defined as the loss of more than 500 ml or 1,000 ml of blood following childbirth. Some have added the requirement that there also be signs or symptoms of low blood volume for the condition to exist. Signs and symptoms may initially include: an increased heart rate, feeling faint upon standing, and an increased breathing rate. As more blood is lost, the patient may feel cold, blood pressure may drop, and they may become restless or unconscious. In severe cases circulatory collapse, disseminated intravascular coagulation and death can occur. The condition can occur up to twelve weeks following delivery in the secondary form. The most common cause is poor contraction of the uterus following childbirth. Not all of the placenta being delivered, a tear of the uterus, or poor blood clotting are other possible causes. It occurs more commonly in those who already have a low amount of red blood, are Asian, have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-pneumatic Anti-shock Garment
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 from obstetrical hemorrhage every year with 99% of cases occurring in developing countries; many of these deaths 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 su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sub-Saharan Africa
Sub-Saharan Africa is the area and regions of the continent of Africa that lie south of the Sahara. These include Central Africa, East Africa, Southern Africa, and West Africa. Geopolitically, in addition to the list of sovereign states and dependent territories in Africa, African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations geoscheme for Africa, United Nations (UN). This is considered a non-standardised geographical region with the number of countries included varying from 46 to 48 depending on the organisation describing the region (e.g. United Nations, UN, World Health Organization, WHO, World Bank, etc.). The Regions of the African Union, African Union (AU) uses a different regional breakdown, recognising all 55 member states on the continent—grouping them into five distinct and standard regions.

Developing World
A developing country is a sovereign state with a less-developed industrial base and a lower Human Development Index (HDI) relative to developed countries. However, this definition is not universally agreed upon. There is also no clear agreement on which countries fit this category. The terms low-and middle-income country (LMIC) and newly emerging economy (NEE) are often used interchangeably but they refer only to the economy of the countries. The World Bank classifies the world's economies into four groups, based on gross national income per capita: high-, upper-middle-, lower-middle-, and low-income countries. Least developed countries, landlocked developing countries, and small island developing states are all sub-groupings of developing countries. Countries on the other end of the spectrum are usually referred to as high-income countries or developed countries. There are controversies over the terms' use, as some feel that it perpetuates an outdated concept of "us" and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tranexamic Acid
Tranexamic acid is a medication used to treat or prevent excessive blood loss from major trauma, postpartum bleeding, surgery, tooth removal, nosebleeds, and heavy menstruation. It is also used for hereditary angioedema. It is taken either by mouth, injection into a vein, or by intramuscular injection. Tranexamic acid is a synthetic analog of the amino acid lysine. It serves as an antifibrinolytic by reversibly binding four to five lysine receptor sites on plasminogen. This decreases the conversion of plasminogen to plasmin, preventing fibrin degradation and preserving the framework of fibrin's matrix structure. Tranexamic acid has roughly eight times the antifibrinolytic activity of an older analogue, ε-aminocaproic acid. Tranexamic acid also directly inhibits the activity of plasmin with weak potency ( IC50 = 87 mM), and it can block the active-site of urokinase plasminogen activator (uPA) with high specificity ( Ki = 2 mM), one of the highest among all the serine ...

Aorta
The aorta ( ; : aortas or aortae) is the main and largest artery in the human body, originating from the Ventricle (heart), left ventricle of the heart, branching upwards immediately after, and extending down to the abdomen, where it splits at the aortic bifurcation into two smaller arteries (the common iliac artery, common iliac arteries). The aorta distributes Oxygen saturation (medicine), oxygenated blood to all parts of the body through the systemic circulation. Structure Sections In anatomical sources, the aorta is usually divided into sections. One way of classifying a part of the aorta is by anatomical compartment, where the thoracic aorta (or thoracic portion of the aorta) runs from the heart to the thoracic diaphragm, diaphragm. The aorta then continues downward as the abdominal aorta (or abdominal portion of the aorta) from the diaphragm to the aortic bifurcation. Another system divides the aorta with respect to its course and the direction of blood flow. In this s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Misoprostol
Misoprostol is a synthetic prostaglandin medication used to prevent and treat stomach and duodenal ulcers, induce labor, cause an abortion, and treat postpartum bleeding due to poor contraction of the uterus. It is taken by mouth when used to prevent gastric ulcers in people taking nonsteroidal anti-inflammatory drugs (NSAID). For abortions it is typically used in conjunction with mifepristone or methotrexate, but can be used alone. By itself, effectiveness for abortion is between 82% and 100%. Its efficacy with mifepristone is higher, but varies based on gestational age. The misoprostol-only abortion regimen is typically recommended only when mifepristone is not available. For labor induction or abortion, it is taken by mouth, dissolved in the mouth, or placed in the vagina. For postpartum bleeding it may also be used rectally. Common side effects include diarrhea and abdominal pain. It is in pregnancy category X, meaning that it is known to result in negative outcomes f ...

Oxytocin
Oxytocin is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. Present in animals since early stages of evolution, in humans it plays roles in behavior that include Human bonding, social bonding, love, reproduction, childbirth, and the Postpartum period, period after childbirth. Oxytocin is released into the bloodstream as a hormone in response to Human sexual activity, sexual activity and during childbirth. It is also available in Oxytocin (medication), pharmaceutical form. In either form, oxytocin stimulates uterine contractions to speed up the process of childbirth. In its natural form, it also plays a role in maternal bonding and lactation, milk production. Production and secretion of oxytocin is controlled by a positive feedback mechanism, where its initial release stimulates production and release of further oxytocin. For example, when oxytocin is released during a contraction of the uterus at the start of c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Episiotomy
Episiotomy, also known as perineotomy, is a surgical incision of the perineum and the posterior vaginal wall generally done by an obstetrician. This is usually performed during the second stage of labor to quickly enlarge the aperture, allowing the baby to pass through. The incision, which can be done from the posterior midline of the vulva straight toward the anus or at an angle to the right or left (medio-lateral episiotomy), is performed under local anesthetic ( pudendal anesthesia), and is sutured after delivery. Its routine use is no longer recommended, as perineal massage applied to the vaginal opening, is an alternative to enlarge the orifice for the baby. It was once one of the most common surgical procedures specific to women. In the United States, as of 2012, it was performed in 12% of vaginal births. It is also widely practiced in many parts of the world, including Korea, Japan, Taiwan, China, and Spain in the early 2000s. Uses Vaginal tears can occur during c ...

Forceps In Childbirth
Obstetrical forceps are a medical instrument used in childbirth. Their use can serve as an alternative to the ventouse (vacuum extraction) method. Medical uses Forceps births, like all assisted births, should be undertaken only to help promote the health of the mother or baby. In general, a forceps birth is likely to be safer for both the mother and baby than the alternatives – either a ventouse birth or a caesarean section – although caveats such as operator skill apply. Advantages of forceps use include avoidance of caesarean section (and the short and long-term complications that accompany this), reduction of delivery time, and general applicability with cephalic presentation (head presentation). Common complications include the possibility of bruising the baby and causing more severe vaginal tears (perineal laceration) than would otherwise be the case. Severe and rare complications (occurring less frequently than 1 in 200) include nerve damage, Descemet's membrane r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caesarean Sections
Caesarean section, also known as C-section, cesarean, or caesarean delivery, is the Surgery, surgical procedure by which one or more babies are Childbirth, delivered through an incision in the mother's abdomen. It is often performed because vaginal delivery would put the mother or child at risk (of paralysis or even death). Reasons for the operation include, but are not limited to, obstructed labor, twin pregnancy, pre-eclampsia, high blood pressure in the mother, breech birth, shoulder presentation, and problems with the placenta or umbilical cord. A caesarean delivery may be performed based upon the shape of the mother's pelvis or history of a previous C-section. A trial of Vaginal birth after previous C-section, vaginal birth after C-section may be possible. The World Health Organization recommends that caesarean section be performed only when medically necessary. A C-section typically takes 45 minutes to an hour. It may be done with a spinal block, where the woman is awake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obese
Obesity is a medical condition, considered by multiple organizations to be a disease, in which excess body fat has accumulated to such an extent that it can potentially have negative effects on health. People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over ; the range is defined as overweight. Some East Asian countries use lower values to calculate obesity. Obesity is a major cause of disability and is correlated with various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity has individual, socioeconomic, and environmental causes. Some known causes are diet, low physical activity, automation, urbanization, genetic susceptibility, medications, mental disorders, economic policies, endocrine disorders, and exposure to endocrine-disrupting chemicals.
