Abstract

Ultrasound is the essential method for diagnosis in obstetrics and gynecology. The continuous increase in resolution of transducers allows a precise introduction of a needle in the amniotic cavity and the ultrasound-guided techniques are diagnostic and therapeutic safe procedures. In this category is included cordocentesis [(percutaneous umbilical blood sampling (PUBS)] that allows the access to the fetal blood vessels and the replacement of the initial fetoscopic monitoring. Usually, this method cordocentesis (PUBS) has become a largely used technique in order to obtain fetal blood and to perform fetal intrauterine transfusions. This chapter covers the indications of cordocentesis, technique of cordocentesis, and complications of cordocentesis. The technique of cordocentesis can be performed by one operator or with the help of an assistant (when one introduces the needle and the other one has to hold the transducer). The patient can be hospitalized or the procedure can be performed in an outpatient manner. Sedation, antibiotics, tocolysis or paralyzing medication for the fetus is not necessary.
