Midwifery


Midwifery is the health science and health profession that deals with pregnancy, childbirth, and the postpartum period, in addition to the sexual and reproductive health of women throughout their lives. In many countries, midwifery is a medical profession. A professional in midwifery is known as a midwife.
A 2015 Cochrane review concluded that "most women should be offered midwifery-led continuity models of care and women should be encouraged to ask for this option although caution should be exercised in applying this advice to women with substantial medical or obstetric complications." The review found that midwifery-led care was associated with a reduction in the use of epidurals, with fewer episiotomies or instrumental births, and a decreased risk of losing the baby before 24 weeks' gestation. However, midwifery-led care was also associated with a longer mean length of labor as measured in hours.

Main areas of midwifery

Pregnancy

First trimester

Trimester means "three months". A normal pregnancy lasts about nine months and has three trimesters.
First trimester screening varies by country. Women are typically offered urinalysis and blood tests including a complete blood count, blood typing, syphilis, hepatitis, HIV, and rubella testing. Additionally, women may have chlamydia testing via a urine sample, and women considered at high risk are screened for sickle cell disease and thalassemia. Women must consent to all tests before they are carried out. The woman's blood pressure, height and weight are measured. Her past pregnancies and family, social, and medical history are discussed. Women may have an ultrasound scan during the first trimester which may be used to help find the estimated due date. Some women may have genetic testing, such as screening for Down syndrome. Diet, exercise, and common disorders of pregnancy such as morning sickness are discussed.

Second trimester

The mother visits the midwife monthly or more often during the second trimester. The mother's partner and/or the birth companion may accompany her. The midwife will discuss pregnancy issues such as fatigue, heartburn, varicose veins, and other common problems such as back pain. Blood pressure and weight are monitored and the midwife measures the mother's abdomen to see if the baby is growing as expected. Lab tests such as a UA, CBC, and glucose tolerance test are done if clinically indicated.

Third trimester

In the third trimester the midwife will see the mother every two weeks until week 36 and every week after that. Weight, blood pressure, and abdominal measurements will continue to be done. Lab tests such as a CBC and UA may be done with additional testing done for at-risk pregnancies. The midwife palpates the woman's abdomen to establish the lie, presentation and position of the fetus and later, the engagement. A pelvic exam may be done to see if the mother's cervix is dilating. The midwife and the mother discuss birthing options and write a birth care plan.

Childbirth

Labor and delivery

Midwives are qualified to assist with a normal vaginal delivery while more complicated deliveries are handled by a health care provider who has had further training. Childbirth is divided into four stages.
Following the birth, if the mother had an episiotomy or a tearing of the perineum, it is sutured. The midwife does regular assessments for uterine contraction, fundal height, and vaginal bleeding. Throughout labor and delivery the mother's vital signs are closely monitored and her fluid intake and output are measured. The midwife also monitors the baby's pulse rate, palpates the mother's abdomen to monitor the baby's position, and does vaginal examinations as indicated. If the birth deviates from the norm at any stage, the midwife requests assistance from the multi-disciplinary team.

Birthing positions

Until the last century most women have used both the upright position and alternative positions to give birth. The lithotomy position was not used until the advent of forceps in the seventeenth century and since then childbirth has progressively moved from a woman supported experience in the home to a medical intervention within the hospital.
There are significant advantages to assuming an upright position in labor and birth, such as stronger and more efficient uterine contractions aiding cervical dilatation, increased pelvic inlet and outlet diameters and improved uterine contractility. Upright positions in the second stage include sitting, squatting, kneeling, and being on hands and knees.

Postpartum period

For women who have a hospital birth, the minimum hospital stay is six hours. Women who leave before this do so against medical advice. Women may choose when to leave the hospital. Full postnatal assessments are conducted daily whilst inpatient, or more frequently if needed. A postnatal assessment includes the woman's observations, general well-being, breasts, abdominal palpation to check for involution of the uterus, or a check of her caesarean wound, a check of her perineum, particularly if she tore or had stitches, reviewing her lochia, ensuring she has passed urine and had her bowels open and checking for signs and symptoms of a DVT. The baby is also checked for jaundice, signs of adequate feeding, or other concerns. The baby has a nursery exam between six and seventy two hours of birth to check for conditions such as heart defects, hip problems, or eye problems.
In the community, the community midwife sees the woman at least until day ten. This does not mean she sees the woman and baby daily, but she cannot discharge them from her care until day ten at the earliest. Postnatal checks include neonatal screening test around day five. The baby is weighed and the midwife plans visits according to the health and needs of mother and baby. They are discharged to the care of the health visitor.

Care of the newborn

At birth, the baby receives an Apgar score, at the least, one minute and five minutes of age. This is a score out of 10 that assesses the baby on five different areas—each worth between 0 and 2 points. These areas are: colour, respiratory effort, tone, heart rate, and response to stimuli. The midwife checks the baby for any obvious problems, weighs the baby, and measure head circumference. The midwife ensures the cord has been clamped securely and the baby has the appropriate name tags on. Babies lengths are not routinely measured. The midwife performs these checks as close to the mother as possible and returns the baby to the mother quickly. Skin-to-skin is encouraged, as this regulates the baby's heart rate, breathing, oxygen saturation, and temperature—and promotes bonding and breastfeeding.
In some countries, such as Chile, the midwife is the professional who can direct neonatal intensive care units. This is an advantage for these professionals, who can use the knowledge of perinatology to bring a high quality care of the newborn, with medical or surgical conditions.

Midwifery-led continuity of care

Midwifery-led continuity of care is where one or more midwives have the primary responsibility for the continuity of care for childbearing women, with a multidisciplinary network of consultation and referral with other health care providers. This is different from "medical-led care" where an obstetrician or family physician is primarily responsible. In "shared-care" models, responsibility may be shared between a midwife, an obstetrician and/or a family physician. The midwife is part of very intimate situations with the mother. For this reason, many say that the most important thing to look for in a midwife is comfort with them, as one will go to them with every question or problem.
According to a Cochrane review of public health systems in Australia, Canada, Ireland, New Zealand and the United Kingdom, "most women should be offered midwifery-led continuity models of care and women should be encouraged to ask for this option although caution should be exercised in applying this advice to women with substantial medical or obstetric complications." Midwifery-led care has effects including the following:
  • a reduction in the use of epidurals, with fewer episiotomies or instrumental births.
  • a longer mean length of labour as measured in hours
  • increased chances of being cared for in labour by a midwife known by the childbearing woman
  • increased chances of having a spontaneous vaginal birth
  • decreased risk of preterm birth
  • decreased risk of losing the baby before 24 weeks' gestation, although there appears to be no differences in the risk of losing the baby after 24 weeks or overall
There was no difference in the number of Caesarean sections. All trials in the Cochrane review included licensed midwives, and none included lay or traditional midwives. Also, no trial included out of hospital birth.
Compared to women in other care models, women in continuity models of midwifery care are more satisfied with their care. The updated version of the Cochrane review also shows a cost-saving effect in continuity models, compared to other midwifery models of care.
In continuity models of midwifery care, the midwife-woman relationship is developing over time. The deepened relationship has shown to be of great importance and is in a described as "the vehicle through which personalised care, trust and empowerment are achieved in the continuity of care midwifery model".
In some cultures, midwifery is the most traditional way of carrying out a pregnancy and childbirth, and it has been conducted for multiple generations. Child birthing women in these cultures, take Zimbabwe for example, feel that health facilities are not as comforting as cultural roots of care. Also, according to the World Health Organization, women should be able to have their children where ever they feel the most safe, so if having a midwife and proceeding with an at-home birth is what makes some women feel safe, then midwifery-led continuity of care might be the best option for them.
