Percutaneous umbilical cord blood sampling prepared with an anticoagulant, which helps to reduce the risk of clot formation. During the procedure, the first step is to locate a relatively stable segment of the umbilical cord. A typical sampling site would be where the segment of the umbilical cord is closest to the placenta. However, there is a risk of maternal blood contamination at this site. Blood sampling may be achieved with more ease if the placenta is in the anterior position. However, if the placenta is in the posterior position, the fetus might block direct access to the umbilical cord. Once the umbilical cord is
Souffle (heart sound) the rush of blood through the dilated vessels of the uterus. On auscultation, uterine souffle may often be confused with funic souffle, which is a sharp, whistling sound that is synchronous with the pulse of the foetus. Therefore, the maternal pulse must be palpated simultaneously in order to confirm uterine souffle. Uterine souffle is considered as a probable objective sign of pregnancy. Funic souffle (also known as funicular or fetal souffle), is a blowing sound heard in synch with fetal heart sounds, and may originate from the umbilical cord. It has also been described as a sharp, whistling sound that
