The Role of Ultrasonography in the Non Invasive management of Rh ISO-Immunization – A Review from Case Reports

These three cases were examples of rhesus iso immunisation. All three cases were managed successfully using current conservative guides in ultrasonography for rhesus iso-immunization. The use of Uitrasound doppler had helped us to decide the timing and immediate neonatal management. In an ideal situation detection of fetal anaemia less than 9g/dl is an indication for intra uterine transfusion guided through cordocentesis. The transfusion is done using O Rh negative leucocytes depleted washed irradiated red cells crossed matched for maternal blood. However we are in the process of arranging this facility through national blood bank. At present we adopt a policy of cordocentesis for fetal Hb in suspected cases of fetal anemia and timely delivery while arranging the neonatal backup for exchange transfusion. This article further discusses the important aspects like pathophysiology, role of different Ultrasound scan parameters and their limitations.
