| version, foetal | The manual conversion of or changing of the polarity of the foetus with reference to the mother. (12 Dec 1998) |
|---|---|
| maternal-foetal exchange | Exchange of substances between the maternal blood and the foetal blood through the placental barrier. It excludes microbial or viral transmission. (12 Dec 1998) |
| persistent foetal circulation syndrome | <syndrome> A syndrome of persistent pulmonary hypertension in the newborn infant, without demonstrable cardiac disease. It is characterised by cyanosis and acidosis, severe pulmonary vasoconstriction, hypertrophy of pulmonary arterial muscle, and elevated pulmonary vascular resistance, with resultant right-to-left shunting of blood through a patent ductus arteriosus and at times a patent foramen ovale. (12 Dec 1998) |
| circulation, foetal | The blood circulation in the foetus (the unborn baby). Before birth, the blood from the heart that is destined (in the pulmonary artery) for the lungs is shunted away from the lungs and returned to the greatest of arteries (the aorta). The shunt is through a short vessel called the ductus arteriosus. When this shunt is open, it is said to be a patent (pronounced pá tent) ductus arteriosus (PDA). The PDA usually closes at or shortly after birth and blood is permitted to course freely to the lungs. (12 Dec 1998) |
| mild foetal bradycardia | A foetal heart rate less than 120 beats per minute. (05 Mar 2000) |
| mortality rate, foetal | The ratio of foetal deaths to the sum of the births (the live births + the foetal deaths) in that year. In the united states, the foetal mortality rate plummeted from 19.2 per 1,000 births in 1950 to 9.2 per 1,000 births in 1980. (12 Dec 1998) |
| heart rate, foetal | The heart rate of the foetus. The normal range at term is between 120 and 160 beats per minute. (12 Dec 1998) |
| hereditary persistence of foetal haemoglobin | <haematology> Hereditary persistence of foetal haemoglobin is a genetic condition where adult types of haemoglobin fail to develop and the types of haemoglobin the individual had as a foetus remains present well past the point when they would normally have stopped being produced. (09 Oct 1997) |
| hypoplastic foetal chondrodystrophy | A developmental error of the epiphyses characterised by severe deformities, epiphyses ossified from several discrete centres and with a stippled appearance, and thickened shafts of the long bones; congenital cataract and mental retardation are often present. There is an autosomal dominant form and an autosomal recessive form. Synonym: chondrodysplasia punctata, chondrodystrophia calcificans congenita, hypoplastic foetal chondrodystrophy, stippled epiphysis. (05 Mar 2000) |
| syndrome, foetal alcohol | The sum total of a person's problems caused by maternal alcohol intake during pregancy. (12 Dec 1998) |
| dystocia, foetal | Dystocia caused by the foetus due to its size (too big), shape or position in the uterus. (12 Dec 1998) |
| erythroblastosis, foetal | Haemolytic anaemia of the foetus or newborn infant, caused by the transplacental transmission of maternally formed antibody, usually secondary to an incompatibility between the blood group of the mother and that of her offspring. (12 Dec 1998) |
| foetal | Of or pertaining to a foetus, pertaining to in utero development after the embryonic period. (18 Nov 1997) |
| foetal adrenal cortex | An extensive area of the adrenal gland present in primates during foetal life and for a short period after birth; located between the definitive cortex and the medulla, it contains large steroid-secreting cells arranged in a reticular pattern; involution of this zone in humans is largely completed by three months after birth. Synonym: androgenic zone, foetal reticularis, foetal zone, provisional cortex. (05 Mar 2000) |
| foetal age | Age estimated by anatomic development since implantation, the degree of anatomic, physiologic, mental, and emotional maturation. Synonym: foetal age. (05 Mar 2000) |
