Re: US markers for fetal anemia

Hi,

Cordocentesis is not difficult. My first, in a hydropic fetus that would otherwise die, was successful on the fourth attempt and I was the third physician to try. Since then they have become much easier. However it does carry a small but definite risk for loss of about 1% or so. One of my former fellows lost a baby who kicked the needle during transfusion and bled out (Bottom line - paralyze the baby as soon as you get in for a transfusion, be ready to go, draw your initial, do the transfusion, draw the final & get out).

The vena cava findings of pulsatility and reversed flow with atrial kick may precede hydrops and I would act on this - especially if the change extended into the UV.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
