  • Title: [Automated exchange transfusion in premature and newborn infants with hyperbilirubinemia using a peripheral arteriovenous vascular access device].

    Journal: Wien Klin Wochenschr; 1990 Aug 31; 102(16):471-5. PubMed ID: 2219940.
    Abstract:
    The technique of exchange transfusion using a plastic catheter in the umbilical vein developed by Diamond and modified by Allen was instrumental in decreasing the mortality and morbidity in newborn infants with jaundice. Allen et al. demonstrated that the development of kernicterus in infants with erythroblastosis with indirect hyperbilirubinemia could be prevented by this method. Since that time numerous modifications of this "single site, push pull technique" have been described to further reduce the risk of morbidity and mortality. On the basis of the successful use of percutaneous radial artery catheters for arterial blood gas monitoring, we developed a technique for exchange transfusion using a peripheral arterial catheter inserted in the radial artery for blood withdrawal and a peripheral venous catheter for replacement of heparinized compatible donor blood. For simultaneous withdrawal and replacement we used two volumetric infusion pumps, one aspirating patients' arterial blood, the other replacing equal volumes of donor blood at exactly the same time. We evaluated our new procedure in 19 newborn infants (group 1) with hyperbilirubinemia who required exchange transfusion. Retrospectively we analysed the data in 18 newborn infants (group 2) treated over a previous period by means of the conventional "one site, push pull" technique using the umbilical vein, and compared the data. Mean birth weights, gestational ages and Apgar scores were similar in both groups, as were volumes of blood used for exchange transfusions. The results were superior in group 1 infants, as reflected by the significantly greater percentage decreases in serum bilirubin concentration and fewer complications.
