| foetal calf serum | <cell culture> The serum originating from embryonic calves and an expensive component of standard culture media for many types of animal tissue cells. It is used as an important part of growth media for promoting the growth of tissue cultures. It provides a source of growth hormones and other growth factors. (11 Nov 1997) |
| foetal circulation | The blood circulation in the foetus before birth. Before birth, the blood from the heart headed for the lungs in the aptly named pulmonary artery is shunted away from the lungs and returned to the greatest of arteries, the aorta. This arterial shunting occurs through a short vessel called the ductus arteriosus. When the shunt is open, it is said to be patent (pronounced pá tent). The ductus arteriosus usually tourniquets itself off at or shortly after birth. After closure of the ductus, blood is permitted from that time on to course freely to the lungs. Sometimes, however, the patent ductus arteriosus (PDA) persists and simply will not close by itself. Surgery is then done to ligate (tie off) the ductus PDA ligation is a closed-heart operation. Historically, it was one of the earliest surgical procedures performed in children with cardiovascular disease. (12 Dec 1998) |
| foetal cotyledon | A unit of the foetal placenta supplied by the vessels of a stem villus; several such cotyledon's may occur between two placental septa; traditionally called embryologists' cotyledon. (05 Mar 2000) |
| foetal death | <radiology> No foetal movement, no foetal heart movement, scalp oedema, Spalding's sign, hyperextended spine, thrombus within heart (12 Dec 1998) |
| foetal death rate | The number of foetal deaths divided by the sum of live births and foetal deaths occurring in the same population during the same time period. Synonym: stillbirth rate. (05 Mar 2000) |
| foetal development | Morphologic and physiologic growth and development of the mammalian embryo or foetus. (12 Dec 1998) |
| foetal distress | Compromise of the foetus during the antepartum period (before labour) or intrapartum period (birth process). (12 Dec 1998) |
| foetal doppler study | <radiology> Non-stress test (NST), external monitoring for 20 minutes; poor specificity, greater than4 foetal heart accelerations (greater than15 bpm over baseline for 15 seconds) following foetal movement in foetus greater than34 weeks, no heart accelerations in immaturity, sleep, maternal sedation contraction stress test (CST), external monitoring after oxytocin or maternal breast stimulation, greater than 3 uterine contraction in 10 minutes; 50% specificity uterine and umbilical artery waveform, elevated systolic:diastolic ratio = increased vascular resistance foetal aortic flow volume, 185-246 ml/kg/min see also: biophysical profile, intrauterine growth retardation (IUGR) (12 Dec 1998) |
| foetal dystocia | Difficult labour and delivery caused by the foetus' size (too big), shape or position. Dystocia comes from the Greek dys meaning difficult, painful, disordered, abnormal + tokos meaning birth. (12 Dec 1998) |
| foetal electrocardiography | Recording the electrocardiogram of the foetus in utero. (05 Mar 2000) |
| foetal erythroblastosis | <haematology> A condition which develops in the foetus due to an incompatibility between the mother's blood type (RH factor) and the baby's. Maternal antibodies, which enter the foetal circulation during delivery attack the baby's red blood cells leading to haemolysis (rupture of the cells). Symptoms include an infant with an enlarged liver and spleen, swelling, jaundice and anaemia. (27 Sep 1997) |
| foetal face syndrome | <syndrome> A syndrome of facies resembling an early foetus with short forearms, and genital hypoplasia at birth, but without evidence of achondroplasia; leads to dwarfism without mental retardation. Synonym: Robinow's syndrome. (05 Mar 2000) |
| foetal fracture | A fracture of one or more bones of a foetus occurring before birth. Synonym: foetal fracture. (05 Mar 2000) |
| foetal gigantism | Excessive foetal or newborn size, e.g., cerebral gigantism and infants of diabetic mothers. (05 Mar 2000) |
