Obstretic medicine: interdisciplinary care for pregnancy and for women wishing to conceive.

The concept of 'obstetrical medicine' was established in the late 19th century, but overshadowed during most of the 20th century by dramatic improvements in surgical, anesthetic, antimicrobial therapeutics, and obstetrical methods and practice. During the last quarter of the 20th century the causes of maternal morbidity and mortality increasingly became pre-existing hereditable and acquired medical disorders and treatable or preventable medical complications of pregnancy. The role of obstetric medicine re-emerged because of surgical, therapeutic, and medical success. New professional associations have been formed to support, through education and research, the growth in numbers of clinicians from many specialties concerned with the medical care of the pregnant patient.
