Caesarean delivery on maternal request (CDMR) is a caesarean section birth requested by the pregnant woman without a medical reason. [1]
The concept of "Caesarean delivery on maternal request" (CDMR) is not well-recognized in health care, and consequently, when it occurs there are no mechanisms in place for reporting it for research or distinguishing it in medical billing. [2]
Over the last century, delivery by Caesarean section (CS) has become increasingly safer; the medical reasons, therefore, for selecting a CS delivery over a vaginal birth are less likely to be those of necessity, and more likely to be motivated by other factors, such as considerations of pain in vaginal delivery and the effects of childbirth on vaginal muscle tone. Until recently,[ when? ] an elective caesarean section was done on the basis of medical grounds; however, the existence of CDMR makes the mother's preference the determining factor for the delivery mode.
An elective Caesarean will be agreed in advance. An elective Caesarean can be suggested by either the mother or her obstetrician, often as a result of a change in the medical status of the mother or baby. The term is used by the press and on the web in a number of different ways, but any Caesarean section which is not an emergency is classified as elective. The mother in essence has agreed to it but may not have chosen it.[ citation needed ]
The popular media suggest that many women are opting for Caesareans in the belief that it is a practical solution. [3] The ethical view that a woman has the right to make decisions regarding her body has empowered women to make a choice regarding the method of her childbirth. [4]
The movement for CDMR may have started in Brazil. [3] It has been estimated that possibly 4-18% of all CSs are done on maternal request; however, estimates are difficult to come by. [1] The global nature of the CDMR phenomenon was underlined by a study that showed that in southeast China about 20% of women chose this mode of delivery. [5]
Increasingly, caesarean sections are performed in the absence of obstetrical or medical necessity at the patient's request, and the term Caesarean delivery on maternal request has been used. [1] Another term that has been used is "planned elective cesarean section". [6] As of 2006 [update] , there is no ICD code, thus the extent of the use of this indication is difficult to determine. The mother is the only party who may request such an intervention without indication.[ citation needed ]
Caesarean sections are in some cases performed for reasons other than medical necessity. These can vary, with a key distinction being between hospital- or doctor-centric reasons and mother-centric reasons. Critics of doctor-ordered Caesareans worry that Caesareans are in some cases performed because they are profitable for the hospital, because a quick Caesarean is more convenient for an obstetrician than a lengthy vaginal birth, or because it is easier to perform surgery at a scheduled time than to respond to nature's schedule and deliver a baby at an hour that is not predetermined. [7] It is through these lenses that CDMR can sometimes be viewed as an example of unnecessary health care.
Non-medically indicated scheduling of childbirth before 39 weeks gestation brings "significant risks for the baby with no known benefit to the mother." Hospitals should institute strict monitoring of births to comply with full term (more than 39 weeks gestation) elective C-section guidelines. In review, three hospitals following policy guidelines brought elective early deliveries down 64%, 57%, and 80%. [8] The researchers found many benefits but "no adverse effects" in the health of the mothers and babies at those hospitals. [8] [9]
In this context, it is worth remembering many studies have shown operations performed out-of-hours tend to have more complications (both surgical and anaesthetic). [10] For this reason, if a Caesarean is anticipated to be likely to be needed for a woman, it may be preferable to perform this electively (or pre-emptively) during daylight operating hours, rather than wait for it to become an emergency with the increased risk of surgical and anaesthetic complications that can follow from emergency surgery.
Another contributing factor for doctor-ordered procedures may be fear of medical malpractice lawsuits. Italian gynaecologist Enrico Zupi, whose clinic in Rome, Mater Dei, was under media attention for carrying a record of Caesarian sections (90% over total birth), explained: "We shouldn't be blamed. Our approach must be understood. We doctors are often sued for events and complications that cannot be classified as malpractice. So we turn to defensive medicine. We will keep acting this way as long as medical mistakes are not depenalized. We are not martyrs. So if a pregnant woman is facing an even minimum risk, we suggest she gets a C-section". [11]
Studies of United States women have indicated married white women giving birth in private hospitals are more likely to have a Caesarean section than poorer women, although they are less likely to have complications that may lead to a Caesarean section being required. The women in these studies have indicated their preference for Caesarean section is more likely to be partly due to considerations of pain and vaginal tone. [12] In contrast, a 2004 study in the British Medical Journal retrospectively analysed a large number of Caesarean sections in England and stratified them by social class. Their finding was Caesarean sections are not more likely in women of higher social class than in women in other classes. [13] Some have suggested, due to the comparative risks of Caesarean section with an uncomplicated vaginal delivery, women should be discouraged or forbidden from choosing it. [14]
Some 42% of obstetricians[ clarification needed ] believe the media and women are responsible for the rising Caesarean section rates. [15] A study conducted in Sweden, however, concludes that relatively few women wish to deliver by Caesarean section. [16]
Requirements for a second opinion from an additional doctor before giving a caesarean section has a small effect on reducing the rate of unnecessary caesarean sections. [17] Communities of health care providers who peer review each other and come to agreement about the necessity of caesarean sections tend to use them less frequently. [17] When medical guidelines are shared by local community leaders which mothers trust, then those mothers are more likely to have vaginal delivery after having had a previous caesarean delivery. [17] When mothers have access to childbirth classes and relaxation classes mothers are more likely to use vaginal delivery when the pregnancy is otherwise low risk. [17]
A meeting of experts sponsored by the NIH in March, 2006 attempted to address the medical issues and found "insuffient evidence to evaluate fully the benefits and risks" of CDMR versus vaginal delivery, and thus was not able to come to a consensus about the general advisability of a cesarean delivery by demand. [1] The available evidence suggests certain differences as follows:
Proponents for CDMR point out that it facilitates the birth process by performing it at a scheduled time under controlled circumstances, with typically less bleeding, and less risk of trauma to the baby. [1] Furthermore, there is some evidence that urinary stress incontinence as a long-term result of damage to the pelvic floor is increased after vaginal birth. Opponents to CS feel that it is not natural, that the costs are higher, infection rates are higher, hospitalization longer, and rates for breastfeeding decrease. Also, once a CS has been done, subsequent deliveries will likely be also by CS, each time at a somewhat higher risk. Further, babies born after a vaginal delivery tend to be at a lower risk for the infant respiratory distress syndrome. [1]
Subsequent to the NIH report a large review from the USA of almost 6 million births was published that suggested that neonatal mortality is 184% higher in babies born by cesarean section. [18] This study was harshly criticized for excluding cases where unforeseen complications arose during labor from its cohort of vaginal deliveries, thereby retrospectively removing poor outcomes and artificially lowering the neonatal mortality rate in the vaginal delivery population, and for using birth certificate data instead of more reliable documentation, such as hospital discharge forms, to define cesarean sections with "no indicated risk", and thereby inappropriately including emergent cesarean sections in their "elective cesarean" cohort. [19] [20] [21] In response to this criticism, the authors published a second paper analyzing the same cohort, in which they did not systematically exclude vaginal deliveries in which unexpected complications arose, and concluded that the increased risk of neonatal mortality associated with cesarean section was 69%, rather than 184%. However, they did not address the inadequacies of their data set, and did not attempt to determine the degree of error introduced when identifying elective cesarean sections by birth certificate. [22] A study published in the February 13, 2007 issue of the Canadian Medical Association Journal found that between 1991 and 2005, women who had scheduled cesarean sections for breech birth had a 2.7% rate of severe morbidity, compared with 0.9% for women who had planned vaginal deliveries. [23]
Caesarean section, also known as C-section or caesarean delivery, is the surgical procedure by which one or more babies are delivered through an incision in the mother's abdomen, often performed because vaginal delivery would put the baby or mother at risk. Reasons for the operation include obstructed labor, twin pregnancy, 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 C-section may be possible. The World Health Organization recommends that caesarean section be performed only when medically necessary.
A multiple birth is the culmination of one multiple pregnancy, wherein the mother gives birth to two or more babies. A term most applicable to vertebrate species, multiple births occur in most kinds of mammals, with varying frequencies. Such births are often named according to the number of offspring, as in twins and triplets. In non-humans, the whole group may also be referred to as a litter, and multiple births may be more common than single births. Multiple births in humans are the exception and can be exceptionally rare in the largest mammals.
Childbirth, also known as labour, parturition and delivery, is the completion of pregnancy where one or more babies exits the internal environment of the mother via vaginal delivery or caesarean section. In 2019, there were about 140.11 million human births globally. In the developed countries, most deliveries occur in hospitals, while in the developing countries most are home births.
A home birth is a birth that takes place in a residence rather than in a hospital or a birthing center. They may be attended by a midwife, or lay attendant with experience in managing home births. Home birth was, until the advent of modern medicine, the de facto method of delivery. The term was coined in the middle of the 19th century as births began to take place in hospitals.
A breech birth is when a baby is born bottom first instead of head first, as is normal. Around 3–5% of pregnant women at term have a breech baby. Due to their higher than average rate of possible complications for the baby, breech births are generally considered higher risk. Breech births also occur in many other mammals such as dogs and horses, see veterinary obstetrics.
Placenta praevia is when the placenta attaches inside the uterus but in a position near or over the cervical opening. Symptoms include vaginal bleeding in the second half of pregnancy. The bleeding is bright red and tends not to be associated with pain. Complications may include placenta accreta, dangerously low blood pressure, or bleeding after delivery. Complications for the baby may include fetal growth restriction.
Labor induction is the process or treatment that stimulates childbirth and delivery. Inducing (starting) labor can be accomplished with pharmaceutical or non-pharmaceutical methods. In Western countries, it is estimated that one-quarter of pregnant women have their labor medically induced with drug treatment. Inductions are most often performed either with prostaglandin drug treatment alone, or with a combination of prostaglandin and intravenous oxytocin treatment.
Placental abruption is when the placenta separates early from the uterus, in other words separates before childbirth. It occurs most commonly around 25 weeks of pregnancy. Symptoms may include vaginal bleeding, lower abdominal pain, and dangerously low blood pressure. Complications for the mother can include disseminated intravascular coagulopathy and kidney failure. Complications for the baby can include fetal distress, low birthweight, preterm delivery, and stillbirth.
Complications of pregnancy are health problems that are related to, or arise during pregnancy. Complications that occur primarily during childbirth are termed obstetric labor complications, and problems that occur primarily after childbirth are termed puerperal disorders. While some complications improve or are fully resolved after pregnancy, some may lead to lasting effects, morbidity, or in the most severe cases, maternal or fetal mortality.
Fetal surgery also known as antenatal surgery, prenatal surgery, is a growing branch of maternal-fetal medicine that covers any of a broad range of surgical techniques that are used to treat congenital abnormalities in fetuses who are still in the pregnant uterus. There are three main types: open fetal surgery, which involves completely opening the uterus to operate on the fetus; minimally invasive fetoscopic surgery, which uses small incisions and is guided by fetoscopy and sonography; and percutaneous fetal therapy, which involves placing a catheter under continuous ultrasound guidance.
In case of a previous caesarean section a subsequent pregnancy can be planned beforehand to be delivered by either of the following two main methods:
A vaginal delivery is the birth of offspring in mammals through the vagina. It is the most common method of childbirth worldwide. It is considered the preferred method of delivery, with lower morbidity and mortality than Caesarean sections (C-sections).
An asynclitic birth or asynclitism are terms used in obstetrics to refer to childbirth in which there is malposition of the head of the fetus in the uterus, relative to the birth canal. Asynclitic presentation is different from a shoulder presentation, in which the shoulder is presenting first. Many babies enter the pelvis in an asynclitic presentation, and most asynclitism corrects spontaneously as part of the normal birthing process.
A shoulder presentation is a malpresentation at childbirth where the baby is in a transverse lie, thus the leading part is an arm, a shoulder, or the trunk. While a baby can be delivered vaginally when either the head or the feet/buttocks are the leading part, it usually cannot be expected to be delivered successfully with a shoulder presentation unless a cesarean section (C/S) is performed.
A cephalic presentation or head presentation or head-first presentation is a situation at childbirth where the fetus is in a longitudinal lie and the head enters the pelvis first; the most common form of cephalic presentation is the vertex presentation, where the occiput is the leading part. All other presentations are abnormal (malpresentations) and are either more difficult to deliver or not deliverable by natural means.
Psychiatric disorders of childbirth, as opposed to those of pregnancy or the postpartum period, are psychiatric complications that develop during or immediately following childbirth. Despite modern obstetrics and pain control, these disorders are still observed. Most often, psychiatric disorders of childbirth present as delirium, stupor, rage, acts of desperation, or neonaticide. These psychiatric complications are rarely seen in patients under modern medical supervision. However, care disparities between Europe, North America, Australia, Japan, and other countries with advanced medical care and the rest of the world persist. The wealthiest nations represent 10 million births each year out of the world's total of 135 million. These nations have a maternal mortality rate (MMR) of 6–20/100,000. Poorer nations with high birth rates can have an MMR more than 100 times higher. In Africa, India & South East Asia, as well as Latin America, these complications of parturition may still be as prevalent as they have been throughout human history.
Circumvallate placenta is a rare condition affecting about 1-2% of pregnancies, in which the amnion and chorion fetal membranes essentially "double back" on the fetal side around the edges of the placenta. After delivery, a circumvallate placenta has a thick ring of membranes on its fetal surface. Circumvallate placenta is a placental morphological abnormality associated with increased fetal morbidity and mortality due to the restricted availability of nutrients and oxygen to the developing fetus.
Vaginal seeding, also known as microbirthing, is a procedure whereby vaginal fluids are applied to a new-born child delivered by caesarean section. The idea of vaginal seeding was explored in 2015 after Maria Gloria Dominguez-Bello discovered that birth by caesarean section significantly altered the newborn child's microbiome compared to that of natural birth. The purpose of the technique is to recreate the natural transfer of bacteria that the baby gets during a vaginal birth. It involves placing swabs in the mother's vagina, and then wiping them onto the baby's face, mouth, eyes and skin. Due to the long-drawn nature of studying the impact of vaginal seeding, there are a limited number of studies available that support or refute its use. The evidence suggests that applying microbes from the mother's vaginal canal to the baby after cesarean section may aid in the partial restoration of the infant’s natural gut microbiome with an increased likelihood of pathogenic infection to the child via vertical transmission.
Nicholas M. Fisk is an Australian maternal-fetal medicine specialist, academic and researcher. As an obstetrician, Fisk is known for inventing the natural caesarean operation, also referred to as the family centred caesarean section.
Operative vaginal delivery, also known as assisted or instrumental vaginal delivery, is a vaginal delivery that is assisted by the use of forceps or a vacuum extractor.
