Pelvimetry is the measurement of the female pelvis. [1] It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. However, clinical evidence indicate that all pregnant women should be allowed a trial of labor regardless of pelvimetry ...
The same human pelvis, front imaged by X-ray (top), magnetic resonance imaging (middle), and 3-dimensional computed tomography (bottom). The pelvis (pl.: pelves or pelvises) is the lower part of an anatomical trunk, [1] between the abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton [2] (sometimes also called bony pelvis or pelvic skeleton).
A woman's breasts grow during pregnancy, typically 1 to 2 cup sizes. [10] A woman who wore a C cup bra prior to her pregnancy may need to buy an F cup or larger bra while nursing. [11] A woman's torso also grows and her bra band size may increase one or two sizes. [12]
The adoption of the non-lithotomy positions is also promoted by the natural childbirth movement. Being upright during labour and birth can increase the available space within the pelvis by 28–30% giving more room to the baby for rotation and descent.
The term, obstetrical dilemma, was coined in 1960, by Sherwood Larned Washburn, a prominent early American physical anthropologist, in order to describe the evolutionary development of the human pelvis and its relation to childbirth and pregnancy in hominids and non-human primates. [6]
The lithotomy position is a common position for surgical procedures and medical examinations involving the pelvis and lower abdomen, as well as a common position for childbirth in Western nations. The lithotomy position involves the positioning of an individual's feet above or at the same level as the hips (often in stirrups), with the perineum ...
[7] [8] This part of the book contains Brigitte Jordan's essay ("Authoritative Knowledge and Its Construction") along with context for the reader about the other essays in the book. [1] [6] [11] Brigitte Jordan elaborates on the theme of authoritative knowledge in her book Birth in Four Cultures: A Cross cultural Investigation of Childbirth in ...
[2] [5] Along with a concern for medical safety, Jordan also focuses on "maternal attitudes and participation in birth, the birth setting, and the mother's selection of birth attendants." [ 6 ] Jordan uses her observations in the field, alongside academic anthropological sources to analyze birth as it occurs in four different societies.
