Step-by-step explanation:
The Branch of Medicine for Perinatal Care
The branch of medicine that deals with perinatal care is obstetrics. This field specializes in the care of pregnant women, the unborn baby, labor, delivery, as well as the immediate period following birth. By contrast, gynecology deals with the health of the female reproductive systems, neonatology focuses on newborn infants, particularly the ill or premature, and pediatrics involves medical care for children and adolescents. Obstetrics is vital for ensuring the health and safety of both mother and child during the course of pregnancy, childbirth, and the postnatal period. Obstetricians monitor the health of the mother and fetus throughout pregnancy.
During the neonatal period, which spans from birth to the eersteindeatht day, infants experience significant physiological adjustments. The new environment challenges their developing systems, necessitating specialized medical support from perinatal healthcare providers. Reproductive endocrinologists, who have completed training in obstetrics, offer prenatal care which is essential for the reduction of risk during pregnancy and childbirth.
