  2. A simple method to estimate volume for fetal intravascular transfusions

    Fetal. Diagn. Ther. vol. 13(2) pp. 94-7

    A simple method to estimate volume for fetal intravascular transfusions.

    Giannina G, Moise KJ, Dorman K

    We derived a constant termed the transfusion coefficient to simplify the estimation of the fetal intravascular transfusion volume. The product of the estimated fetal weight (g) and 0.02 (transfusion coefficient), estimates the transfusion volume (ml) required to increase the fetal hematocrit by approximately 10 percentage points. Our estimation was comparable to Mandelbrot's technique and better than Plecas' method for estimating fetal transfusion volumes. Utilizing the transfusion coefficient to estimate the intravascular transfusion volume for an anemic fetus…

  3. Percutaneous umbilical transfusion in severe rhesus isoimmunization: resolution of fetal hydrops

    Am. J. Obstet. Gynecol. 1987 vol. 157(6) pp. 1369-75

    Percutaneous umbilical transfusion in severe rhesus isoimmunization: resolution of fetal hydrops.

    Socol ML, MacGregor SN, Pielet BW, Tamura RK, Sabbagha RE

    The rhesus-sensitized fetus with the worst prognosis is one with early onset of hydropic changes. Percutaneous umbilical blood sampling now enables access to the fetal circulation and thereby allows more precise evaluation of fetal anemia and direct intravascular transfusion. A variation of this technique was used in three pregnancies complicated by fetal pericardial effusion, scalp edema, and abdominal ascites before 26 weeks' gestation. Twelve ultrasound-guided percutaneous transfusions of 30 to…
