Percutaneous Umbilical Cord Blood Sampling
=Introduction=Draft
Percutaneous Umbilical Blood Sampling (PUBS) is a pre-natal diagnostic procedure performed during the second trimester (between week 18 to 22) where doctor extract a sample of fetal blood from the vein in the umbilical cord via a fine needle through the abdomen of the mother. The extracted blood can then be used to detect certain anomalies such as chromosome abnormalities such as Down syndrome, Blood Disorders such as Anaemia and certain infections, growth retardation, some birth defects as well as some metabolic disorders. PUBS is usually used when other diagnostic test such as Ultrasound, Amniocentesis, Chorionic Villus Sampling do not yield conclusive result requiring further testing. This pre-natal diagnostic technique is also used to deliver certain therapies such as medicine and blood to the fetus.
Percutaneous Umbilical Blood Sampling (PUBS) is an invasive procedure and although it is a very useful technique in diagnosing several complications it has a long list of potential side effects such as blood loss from the puncture and premature rupture of the membranes. Miscarriage may also occur with the chance of this occurring is 1 to 2 times out of every 100 procedures.
Yet the benefits of PUBS as opposed to other pre-natal diagnostic techniques such as Amniocentesis or Chorionic Villus Sampling (CVS) is that genetic information also known as Karyotypes is available much sooner after the procedure.
