The intravascular transfusion of red cells to a hydropic fetus in such cases has notably improved survival. Nonimmune hydrops fetalis due to maternal parvovirus infection has also been treated successfully with the intravascular transfusion of red cells, whereas fetomaternal hemorrhage has not proved amenable to such therapy. Red blood cell (RBC) transfusions should usually be given only to restore or maintain oxygen delivery to vital organs and tissues. Medical history has clearly documented the importance of blood transfusion in saving lives threatened by acute haemorrhage or severe anaemia. In the formula, a is the amount of donor RBC Hb transfused, b is the estimated fetal body weight, and c is the interval in days from the time of transfusion to the time of donor Hb estimation.

Treatment includes intrauterine blood transfusion before birth or early induction of labor if pulmonary maturity has been established, fetal distress occurs or when the pregnancy reaches 35 to 37 weeks of gestation. Intrauterine exchange transfusion is another approach that might help reduce volume overload, obtain a more stable hematocrit, and increase the interval between transfusions. With this technique, small volumes of blood of the anemic fetus are slowly withdrawn and replaced with the same volume of packed red blood cells [49] .

  1. There are two methods of fetal transfusion: Intrauterine intravascular transfusion (IVT) Intrauetrine intra peritoneal transfusion (IPT) Fetal Transfusion. In 1963, first intraperitoneal transfusion (IPT) was done by Liley. He though that Transfused RBCs will be getting in to venous circulation by sub diaphragmatic lymphatic channels.

Fluid shift during intrauterine transfusion Introduction During intrauterine red cell transfusion, a considerable volume of donor blood is administered in a short period of time. The transfused volume is up to 20 to 60% of initial fetoplacental blood volume, while transfusion-times are merely 10 to 30 minutes. Umbilical cord vessel transfusion is the preferred method, because it permits better absorption of blood and has a higher survival rate than does transfusion through the abdomen. footnote 1 . An intrauterine fetal blood transfusion is done in the hospital. The mother may have to stay overnight after the procedure. Hence for 15 mL of PRBC/kg, a pre-transfusion hct of 32% should rise to approximately 47% when checked several hours after transfusing. Transfuse using irradiated (only infants with birth weights <1.5 kg) filtered to reduce CMV risk, packed red blood cells (Hct ≈ 85%). 7.22: Red Cells for Intrauterine Transfusion (IUT), Leucocyte Depleted.

Conclusions Exposure to transfusion in previous 2 days was an independent risk factor for NEC. After controlling for confounders, no significant differences in mortality and morbidities were observed between infants who had transfusion-associated NEC and those with NEC not associated with transfusion. While the practice of transfusion of blood products to neonatal and pediatric recipients has much in common with the transfusion of blood products to adults, there are several important differences and special circumstances. This chapter highlights the most common considerations that are unique to this group of patients. The centrifugal force of each control volume [[??].sub.c] can be calculated by the following formula: Study of the Effect of Centrifugal Force on Rotor Blade Icing Process The centrifugal microfluidic system uses the centrifugal force to drive and control the microfluids through a variety of burst frequencies. Our methods for treatment of severe fetal alloimmune anemia with intrauterine transfusion have been described previously 8. In short, a pretransfusion sample is taken to measure the hemoglobin concentration and hematocrit. The required amount of donor blood is determined by the formula proposed by Rodeck et al. 9: Intrauterine transfusion for fetal anemia due to red blood cell alloimmunization: 14 years experience in Leuven S.A.

In this report fetal outcome after intravascular transfusion was evaluated in a national single‐center cohort, representing the results of intrauterine treatment for red‐cell alloimmunization in the Netherlands. Red‐cell alloimmunization affects up to 0.6% of all live births, and can be successfully treated with intrauterine fetal blood transfusion (IUT). Doppler measurement of fetal middle cerebral artery (MCA) peak systolic velocity (PSV) is a non‐invasive test that can identify fetuses at risk of anemia and in need of IUT 1 .

Anti-D should be given within 72 hours after birth to reduce the risk of RhD complications in rhesus-negative women who have given birth to a rhesus-positive child. A partial exchange transfusion (PET) aims to decrease the hematocrit to a target packed cell volume of 55%. Following partial exchange transfusion, symptoms like jitteriness may persist for 1-2 days despite the hematocrit being lowered to physiological ranges. The volume of blood to be exchanged is given by the formula shown in the box.
