Types of abortion Spontaneous abortion Main write-up Miscarriage A complete spontaneous abortion at about six weeks from conception i e eight weeks from LMP Spontaneous abortion also identified as miscarriage is the expulsion of an embryo or fetus due to accidental trauma or natural causes ahead of approximately the 22nd week of gestation the definition by gestational age varies by nation Most miscarriages are due to incorrect replication of chromosomes they can also be brought on by environmental variables A pregnancy that ends ahe ad of 37 weeks of gestation resulting in a live born infant is identified as a premature birth When a fetus dies in utero following about 22 weeks or during delivery it is in most cases termed stillborn Premature births and stillbirths are frequently not regarded as to be miscarriages while usage of these terms can at times overlap Among 10 and 50 of pregnancies end in clinically apparent miscarriage depending upon the age and health of the pregnant woman Most miscarriages take place quite early in pregnancy in most instances they take place so early in the pregnancy that the woman is not even aware that she was pregnant One study testing hormones for ovulation and pregnancy discovered that 61 9 of conceptuses were lost prior to 12 weeks and 91 7 of these losses occurred subclinically with out the information of the when pregnant woman The danger of spontaneous abortion decreases sharply following the 10th week from the last menstrual period LMP One study of 232 pregnant fem ales showed virtually complete pregnancy loss by the end of the embryonic period 10 weeks LMP with a pregnancy loss rate of only two percent following 8 5 weeks LMP The most standard result in of spontaneous abortion during the first trimester is chromosomal abnormalities of the embryo fetus accounting for at least 50 of sampled early pregnancy losses Other causes incorporate vascular disease such as lupus diabetes other hormonal issues infection and abnormalities of the uterus Advancing maternal age and a patient history of earlier spontaneous abortions are the two top variables related with a higher danger of spontaneous abortion A spontaneous abortion can also be brought on by accidental trauma intentional trauma or pressure to result in miscarriage is regarded as induced abortion or feticide Induced abortion A pregnancy can be intentionally aborted in a variety of strategies The manner selected depends chiefly upon the gestational age of the embryo or fetus which increas es in size as it ages Precise procedures may perhaps also be selected due to legality regional availability and physician patient preference Causes for procuring induced abortions are usually characterized as either therapeutic or elective An abortion is medically referred to as therapeutic when it is performed to save the life of the pregnant woman preserve the woman s physical or mental health terminate pregnancy that would result in a youngster born with a congenital disorder that would be fatal or related with substantial morbidity or selectively lessen the quantity of fetuses to lessen health risks related with numerous pregnancy An abortion is referred to as elective when it is performed at the request of the woman for reasons other than maternal health or fetal disease Abortion strategies Gestational age may perhaps figure out which abortion strategies are practiced Medical Main write-up Medical abortion Medical abortions are non surgical abortions that use pharmaceut ical drugs and are only effective in the first trimester of pregnancy citation needed Medical abortions comprise 10 of all abortions in the United States and Europe citation needed Combined regimens incorporate methotrexate or mifepristone followed by a prostaglandin either misoprostol or gemeprost misoprostol is applied in the U S gemeprost is applied in the UK and Sweden When applied within 49 days gestation approximately 92 of females undergoing medical abortion with a combined regimen completed it with out surgical intervention Misoprostol can be applied alone but has a lower efficacy rate than combined regimens In instances of failure of medical abortion vacuum or manual aspiration is applied to complete the abortion surgically Surgical A vacuum aspiration abortion at eight weeks gestational age six weeks following fertilization 1 Amniotic sac two Embryo three Uterine lining four Speculum 5 Vacurette 6 Attached to a suction pump In the first 12 weeks suction aspiration or vacuum abortion is the most standard system Manual Vacuum aspiration MVA abortion consists of removing the fetus or embryo placenta and membranes by suction employing a manual syringe even though electric vacuum aspiration EVA abortion uses an electric pump These approaches are comparable and differ in the mechanism applied to apply suction how early in pregnancy they can be applied and if cervical dilation is necessary MVA also identified as mini suction and menstrual extraction can be applied in quite early pregnancy and does not need cervical dilation Surgical approaches are at times referred to as Suction or surgical Termination Of Pregnancy Quit From the 15th week until approximately the 26th dilation and evacuation D E is applied D E consists of opening the cervix of the uterus and emptying it employing surgical instruments and suction Dilation and curettage D C the second most standard system of abortion is a regular gynecological process performed for a range of r easons such as examination of the uterine lining for possible malignancy investigation of abnormal bleeding and abortion Curettage refers to cleaning the walls of the uterus with a curette The Globe Health Organization recommends this process also named sharp curettage only when MVA is unavailable The term D and C or at times suction curette is applied as a euphemism for the first trimester abortion process whichever the system applied Other approaches must be applied to induce abortion in the second trimester Premature delivery can be induced with prostaglandin this can be coupled with injecting the amniotic fluid with hypertonic solutions containing saline or urea Soon after the 16th week of gestation abortions can be induced by intact dilation and extraction IDX also named intrauterine cranial decompression which calls for surgical decompression of the fetus head ahead of evacuation IDX is at times named partial birth abortion which has been federally banned in the United States A hysterotomy abortion is a process comparable to a caesarean section and is performed beneath general anesthesia It calls for a smaller sized incision than a caesarean section and is applied during later stages of pregnancy From the 20th to 23rd week of gestation an injection to quit the fetal heart can be applied as the first phase of the surgical abortion process to guarantee that the fetus is not born alive Other strategies Bas relief at Angkor Wat Cambodia c 1150 depicting a demon inducing an abortion by pounding the abdomen of a pregnant woman with a pestle Historically a quantity of herbs reputed to possess abortifacient properties have been applied in folk medicine tansy pennyroyal black cohosh and the now extinct silphium see history of abortion The use of herbs in such a manner can result in seriousven lethalide effects such as numerous organ failure and is not advised by physicians Abortion is at times attempted by causing trauma to the abdomen The degree of force if severe can result in critical internal injuries with out necessarily succeeding in inducing miscarriage Both accidental and deliberate abortions of this type can be subject to criminal liability in a variety of nations In Southeast Asia there is an ancient tradition of attempting abortion by way of forceful abdominal massage One of the bas reliefs decorating the temple of Angkor Wat in Cambodia depicts a demon performing such an abortion upon a woman who has been sent to the underworld Reported strategies of unsafe self induced abortion incorporate misuse of misoprostol and insertion of non surgical implements such as knitting needles and clothes hangers into the uterus These strategies are rarely noticed in created nations exactly where surgical abortion is legal and available Health risks Early term surgical abortion is a straightforward process which is safer than childbirth when performed ahead of the 21st week Abortion strategies like most minimally invasive procedures carry a tiny prospective for critical complications The danger of complications can boost depending on how far pregnancy has progressed Girls usually expertise minor discomfort during first trimester abortion procedures In a 1979 study of two 299 patients 97 reported experiencing some degree of discomfort Patients rated the discomfort as getting much less than earache or toothache but additional than headache or backache Neighborhood and general anesthetics are applied during surgical procedures Mental health Main write-up Abortion and mental health The connection among induced abortion and mental health is an area of controversy No scientific analysis has demonstrated a direct causal connection among abortion and poor mental health though some studies have noted that there may perhaps be a statistical correlation Pre current variables in a woman s life such as emotional attachment to the pregnancy lack of social help pre current psychiatric illness and conservat ive views on abortion boost the likelihood of experiencing negative feelings following an abortion In a 1990 critique the American Psychological Association APA discovered that severe negative reactions following abortion are rare and are in line with those following other standard life stresses The APA revised and updated its findings in August 2008 to account for the accumulation of new evidence and again concluded that induced abortion did not lead to increased mental health issues A 2008 critique by a group from the Johns Hopkins Bloomberg School of Public Health concluded that the highest high quality studies discovered few if any mental health differences among females who had abortions and their comparison groups whereas studies with the most flaws reported negative mental health consequences of abortion As of August 2008 the United Kingdom Royal College of Psychiatrists is also performing a systematic critique of the medical literature to update their position statem ent on the subject Some proposed negative psychological effects of abortion have been referred to by pro life advocates as a separate condition named post abortion syndrome However the existence of post abortion syndrome is not recognized by any medical or psychological organization and some physicians and pro choice advocates have argued that the effort to popularize the idea of a post abortion syndrome is a tactic applied by pro life advocates for political purposes Incidence of induced abortion The incidence and reasons for induced abortion vary regionally It has been estimated that approximately 46 million abortions are performed worldwide every year Of these 26 million are mentioned to take place in places exactly where abortion is legal the other 20 million occur exactly where the process is illegal Some nations such as Belgium 11 two per 100 identified pregnancies and the Netherlands 10 6 per 100 have a low rate of induced abortion even though other people like Russia 62 6 per 100 and Vietnam 43 7 per 100 have a comparatively high rate The globe ratio is 26 induced abortions per 100 identified pregnancies By gestational age and system Histogram of abortions by gestational age in England and Wales during 2004 Average is 9 5 weeks Abortion in the United States by gestational age 2004 Data source Centers for Disease Manage and Prevention Abortion rates also vary depending on the stage of pregnancy and the system practiced In 2003 from data collected in those locations of the United States that sufficiently reported gestational age it was discovered that 88 two of abortions were conducted at or prior to 12 weeks 10 four from 13 to 20 weeks and 1 four at or following 21 weeks 90 9 of these were classified as getting been completed by curettage suction aspiration Dilation and curettage Dilation and evacuation 7 7 by medical means mifepristone four by intrauterine instillation saline or prostaglandin and 1 by other such as hysterotomy and hys terectomy The Guttmacher Institute estimated there were two 200 intact dilation and extraction procedures in the U S during 2000 this accounts for 17 of the total quantity of abortions performed that year Similarly in England and Wales in 2006 89 of terminations occurred at or beneath 12 weeks 9 among 13 to 19 weeks and 1 5 at or more than 20 weeks 64 of those reported were by vacuum aspiration 6 by D E and 30 were medical Later abortions are additional standard in China India and other creating nations than in created nations By personal and social variables A bar chart depicting selected data from the 1998 AGI meta study on the reasons females stated for getting an abortion A 1998 aggregated study from 27 nations on the reasons females seek to terminate their pregnancies concluded that standard variables cited to have influenced the abortion choice were desire to delay or end childbearing concern more than the interruption of work or education concerns of monetary or conn ection stability and perceived immaturity A 2004 study in which American females at clinics answered a questionnaire yielded comparable outcomes In Finland and the United States concern for the health risks posed by pregnancy in person instances was not a aspect normally given nonetheless in Bangladesh India and Kenya health concerns were cited by females additional frequently as reasons for getting an abortion 1 of females in the 2004 survey based U S study became pregnant as a result of rape and 5 as a result of incest Another American study in 2002 concluded that 54 of females who had an abortion were employing a form of contraception at the time of becoming pregnant even though 46 were not Inconsistent use was reported by 49 of those employing condoms and 76 of those employing the combined oral contraceptive pill 42 of those employing condoms reported failure by way of slipping or breakage The Guttmacher Institute estimated that most abortions in the United States are o btained by minority females simply because minority females have substantially greater
