Breech birth in the context of "Caesarean sections"

Caesarean section, also known as C-section, cesarean, or caesarean delivery, is the surgical procedure by which one or more babies are 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, 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 C-section typically takes between 45 minutes to an hour to complete. It may be done with a spinal block, where the woman is awake, or under general anesthesia. A urinary catheter is used to drain the bladder, and the skin of the abdomen is then cleaned with an antiseptic. An incision of about 15 cm (5.9 in) is then typically made through the mother's lower abdomen. The uterus is then opened with a second incision and the baby delivered. The incisions are then stitched closed. A woman can typically begin breastfeeding as soon as she is out of the operating room and awake. Often, several days are required in the hospital to recover sufficiently to return home.

A midwife (pl.: midwives) is a health professional who cares for mothers and newborns around childbirth, a specialisation known as midwifery.

The education and training for a midwife concentrates extensively on the care of women throughout their lifespan; concentrating on being experts in what is normal and identifying conditions that need further evaluation. In most countries, midwives are recognised as skilled healthcare providers. Midwives are trained to recognise variations from the normal progress of labour and understand how to deal with deviations from normal. They may intervene in high risk situations such as breech births, twin births, using non-invasive techniques. For complications related to pregnancy and birth that are beyond the midwife's scope of practice, including surgical and instrumental deliveries, they refer their patients to physicians or surgeons. In many parts of the world, these professions work in tandem to provide care to childbearing women. In others, only the midwife is available to provide care, and in yet other countries, many women elect to use obstetricians primarily over midwives.

In obstetrics, a shoulder presentation is a malpresentation at childbirth where the baby is in a transverse lie (its vertebral column is perpendicular to that of the mother), thus the leading part (the part that first enters the birth canal) 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.

In arthropod and vertebrate anatomy, the vertex (or cranial vertex) is the highest point of the head.

In humans, the vertex is formed by four bones of the skull: the frontal bone, the two parietal bones, and the occipital bone. These bones are connected by the coronal suture between the frontal and parietal bones, the sagittal suture between the two parietal bones, and the lambdoid suture between the parietal and occipital bones. Vertex baldness refers to a form of male pattern baldness in which the baldness is limited to the vertex, resembling a tonsure. In childbirth, vertex birth refers to the common head-first presentation of the baby, as opposed to the buttocks-first position of a breech birth.
